A 600+ two day trip up in the CA mountains. She did great but it wen super lean once I reached 5000ft elevation and lost a ton of power. Ah the idiosyncrasies of carburetors.Andrea Mariottihttp://www.blogger.com/profile/01039837607601417017noreply@blogger.com0tag:blogger.com,1999:blog-9009918972487020482.post-41479910546028588902015-05-31T07:48:00.004-07:002015-05-31T08:10:14.621-07:00Head rebuildIf you know anything about the Loop Frame Guzzi community, you know that Patrick Hayes has been advocating for years that 30K miles is pretty much the limit of the valve guides.<br />
<br />
I am here to tell you he is right.<br />
<br />
Mine were all shot, with tolerances in the single digit millimeters range as opposed to 0.05mm to 0.09mm. That's two orders of magnitude off. No wonder I could not keep valve clearance stable and the bike was burning oil and pinging under heavy load.<br />
<br />
Disclaimer: I rebuild my first engine at fourteen. My dad is a mechanical engineer. I have two degrees in engineering. I have replaced the IMS bearing of my Porsche and while at it, I replaced the clutch too. I can do a valve tune up on a Ducati Testastretta engine with my eyes closed. I would advice that you read this for entertainment only and do not attempt it unless you have a similar level of skills. You can do a lot of damage if a valve gets stuck due to improper clearances.<br />
<br />
Tips I learned in this project:<br />
1) To remove the old guides, I tapped them at the top, screwed in a suitable screw and drove them out with a hammer and a rod that fit inside the guide from underneath. This way the blow from the strike would go through the screw and the guide and nothing else. Note: I used a heat gun to heat up the area around the guide for about two minutes before driving the guide out.<br />
2) I measured everything several times and had some sanity check with an expert and replaced one of the valves (see photo, the shiniest one is new). The stem can wear so be sure to measure them too. Ironically the one I replaced is not the one from the worst guide so do not assume anything and just measure and measure again.<br />
3) To install, I froze the new guides overnight and heated the area again with the heat gun. I put some assembly lube on the guide and drove them in. It took about if not more effort than to remove them and that sounds about right since it is an interference fit.<br />
4) If you decide to ream by yourself, do it by hand and make sure you have a lot of patience. Forget those clowns on Youtube that use a power drill, you will never get it right and the guide will be blown in a few thousand miles. Unless you have access (and experience) to a high precision drill press, either pay someone to do it or do it by hand if you are an advanced amateur mechanic. I own a drill press but I do not consider it a high precision one so I did it by hand. The drill press needs to be accurate to within fraction of a degree! One of my guides was an oversize that required a lot of reaming, it took easily more than an hour and many dozen runs cleaning, oiling, reaming and repeat.<br />
5) Lapping can be fun and very useful to assess if you succeeded or it is time to take it all to a machine shop. After you lap the valves, you will see a ring around the head of the valve, that ring needs to be close to the edge and about the same size for all valves and all around. Any deviation from it is a sign that the seat/valve combination is off and it is time to kiss some money goodbye and hire a machinist. The actual values depends on the engine, I got 2 to 3 millimeters seal ring less than a millimeter from the edge. Sorry I do not have photos, I wrote this after I reassembled everything. Oh and yes, she runs fabulous, see video below. This was after a short test ride. I have since put about 100 miles.<br />
<br />
One more take away: before the valve job, the bike would easily loose 400rpm at idle when hot, to the point that it would die at stop light. Now it idles at near the same rpm at all engine temperatures and it stays on and start right up. You can hear her start in the video after a severe hill climb (very hot engine).<br />

This is long overdue. This 30 seconds slideshow covers virtually six months of progress working weekends and some time at night. She is now fully operational and I put few hundreds miles on her. She is a lovely ride for as long as you remember, you are riding a vintage motorcycle so take it easy :-)<br />

I purchased a universal car brake switch, built a simple bracket using anodized aluminum scrap and connected the spring to the lever via the spring that came with the switch. Instead of trying to hide it, I choose to just lay it bare, a functional/industrial look. The bracket was bent 90 degree to receive the switch and then bolted on the mirror clamp. I reckon you could also reverse it and attach the bracket to the lever itself, effectively hiding the switch behind the handlebar while you ride; but again, I did not mind the look so I did not even bothered.<br />
Cost? about $20 total.<br />

No matter how hard and carefully you clean a vintage fuel tank, some crud will still continue to come out. Some is coming from the fuel itself, some, like in my case initially, was just 20 years worth of deposits from sitting in a barn for too long.<br />
Long story short, I have decided to put a massive, non fuel pump, fuel filter before the carbs, especially since my vintage Mikuni do not have filters. Wow, I cannot believe I just write that, who makes carburetors without filters, arg!<br />
<br />
So I purchased a very fine filter (see <a href="http://amzn.com/B000C9WJ8K" target="_blank">Wix 33001</a>
) and a couple of T couplings and put it in the middle of the flow coming from either the main line or the reserve.<br />
The trick is to make sure it stays above the float bowl of the carburetors or, Archimedes will tell you, you are not going to get any fuel. I achieved this by making it rest atop the air filters and carefully routing the fuel lines. Done. It works like a charm and my carbs no longer require cleaning every 5 minutes ;-)<br />
Oh and yes, the dark stuff you see it is crud, the paper filter is actually white. Sold yet?<br />

Thanks to the good people of Norcal Guzzi Owner Group, I have found a fellow Guzzista who had a etxra one in excellent condition considering it is a 40 year old tank!<br />
Here are some shots of the tank and a bunch of other parts I sand blasted and powder coated. Enjoy!<br />

I have been doing business with them and considering my vintage VM28s are nearly one of a kind, they were a life saver! Chad spent time figuring out what parts would fit and he treated me like I was ordering hundreds of dollars of parts when in fact my orders have been very small. A big thank you, Ms Elly would not be alive and soon back on the road without their help!
If you need help with tuning or understanding how VM28s works, there is no better resource than the <a href="http://kawtriple.com/mraxl/">Kawasaki Triple</a> site since these were OEM on these two strokes bikes.Andrea Mariottihttp://www.blogger.com/profile/01039837607601417017noreply@blogger.com0tag:blogger.com,1999:blog-9009918972487020482.post-65692168071407602372014-07-14T19:45:00.000-07:002014-07-14T19:57:10.852-07:00Ms Elly, mostly clothedEngine operational, all electrical work is done, lights and turn signals functional, I am starting to see the light at the end of the tunnel and she looks amazing!<br />

First engine start in probably 20 yearsAfter resolving most of the issues in my previous post, she still would not start. As it turned out, all she needed was a few minutes to fill up the carbs. What you see here is the very first start after my previous attempt a few minutes earlier did not succeed and I decided to let her sit for a minute.<br />

I was so tuned to listen for a loud twin cylinder rumble (like my Ducati) that I nearly missed it. At first it just sounded like the starter picked up revs but I could barely tell the engine was running! In this video the revs are already north of 2000 rpm as the idle speed was way off and so was the air fuel mixture. Still, she is alive! Now the tuning can start.<br />

<li style="text-align: left;">If you clean the carburetors except the main jet because "everything else looked clean, the main jet must be clean too" you are not done. See photo of the main jet finally removed for cleaning and covered in 20 years of crud. I initially decided to leave them alone be since they would not come out. Well I should have known better and to go after them <i>precisely</i> because they would not budge! Lesson learned. Not to give away the ending but after cleaning the main jet, she started right up.</li>
<li style="text-align: left;">You cannot bench test a generator (I said generator, not an alternator). Well you can but you need to provide current to the electromagnet shields or nothing will happen since the rotor needs to actually cross a magnetic field in order to generate current. If you forgot your high school physics, you will disassemble and clean the generator three times looking for a problem that is not there. Ask me how I know.</li>
<li style="text-align: left;">The shift linkage can be installed either outward or inwards, towards the center of the bike. If you install it towards the pegs (outward), the shift pattern is reversed so when you think you are in 1st, you are actually in 5th and so on. Sooooo when you think you are in neutral, you are actually between 4th and 5th in an accidental neutral......Face palm!</li>
<li style="text-align: left;">Timing is everything. Especially if you want to start a 4-stroke engine but your distributor is incorrectly lined up to spark at the exhaust open cycle, two cycles off. Oops.</li>

So I scrapped the idea of top end assembly and first start this weekend. Bummer.<br />
I was however able to finish:<br />
- headlight bucket de-rust, priming and painting<br />
- rear fender and electrical pre-assembly<br />
- Mikuni VM28 re-assembly<br />
- custom made throttle cables<br />
Here is the end result, with the tank and the seat gently dry-fitter for effect :-)<br />

<br />
I received the missing parts from Harper Guzzi, including the brand new half bearings. All squared off, the pistons are exactly the same weight, the connecting rods are within 1g from one another, off they go back into the crankcase.<br />
Then I finally put the transmission on and sure enough I forgot the clutch rod plunger so I had to do it again. Sigh. All well what ends well. I dry fit the top end and realized that it makes the engine assembly too heavy for the upcoming "marriage" back to the frame so I took them off. This is after I was actually contempt to wait another week with the engine sitting on the workbench since since it was the end of a long day and the workweek was looming. Thanks to my wife however, aka my very own tool girl, we did put the engine back on the frame. It was her idea, she knew it meant a lot to me to make progress. What a gal! My wife. The bike too I guess.<br />
But I digress, I then put the new lower cylinder gaskets on, the o-rings on the short studs and dry fit the cylinders again (see photo). This is mostly so I can keep dust from going into the crankcase and on the pistons that I carefully coated with assembly oil.<br />
I then fill up the engine oil and gave it some hand cranks to make sure we start priming the pump and we keep the crankshaft covered in oil. She is in good shape to sit and wait for more progress this weekend. Next, carb rebuild and custom lower throttle cables. Stay tuned.<br />

The fuel tank is looking better now that is all stripped to the metal and that I have removed a ton of rust and paint from it but it has 40 years worth of dings and dents. It will take several rounds of lightly applied filler and sanding to bring it back to life but it will live another day. The good news is that the original petcocks are in good shape, they just need disassemble and cleaning.<br />
The fenders looked pretty good once primed but there are a few spots that need more work so I am spot sanding them and going back until they are perfect. Hopefully I can post the final product soon.Andrea Mariottihttp://www.blogger.com/profile/01039837607601417017noreply@blogger.com0tag:blogger.com,1999:blog-9009918972487020482.post-85633825952687765842014-04-26T08:33:00.001-07:002014-04-26T08:33:19.114-07:00Clutch back on the engine<div class="separator" style="clear: both; text-align: center;">

Special thanks to Patrick H. from Norcal Guzzisti who patiently waited two weeks for me to finish the job to get his clutch centering tool back! I am telling you, Guzzisti are some of the nicest most enjoyable people you will ever meet.

Straight from Mandello Del Lario (Italy), how cool is that? Meanwhile the parts needed for bottom end and top end rebuild are painfully in back order. Sigh. I guess body work and clutch is next while I wait for them.</div>

I took them apart and clean them thoroughly. I have decided that I am going for a patina restoration to keep the character of the bike. It took her 40 years to land here and earn that patina, I think she deserve to show it with pride. So I only re-painted the parts that absolutely needed protection. You can see what I mean on the starter, only the body was repainted to protect it from further decay.<br />
<br />
Breather box and tail light bracket also could use some new paint after removing all the rust and they are now ready for final assembly.<br />

Here is the entrance to Paradise <a href="http://www.thisoldtractor.com/moto_guzzi_loopframe.html">http://www.thisoldtractor.com/moto_guzzi_loopframe.html</a><br />
Thanks to Gregory I found the clearance numbers I was looking for for the connecting rods and the crankshaft and soon I will know if I need to replace the bearings.

Well it works indeed, the molasses bond with the rust releasing sulfuric acid and the parts come out clean. I have been soaking a few parts for a week now and I am amazed. The air box, for example, was dark red it was covered with so much rust. I just checked it today and it is almost metal gray, most of the rust was eaten away by the bath. Love it.<br />

Today I have also started soda blasting some of the engine parts like the push-rods and the heads. They just have crud and some surface rust so soda blasting works great. Here some before and after photos, enjoy. More soon, I just cracked the engine open, stay tuned!<br />
