Here's a link to a photo album I created for a customer's V700 drivetrain rebuild project. Captions are below each photo. It will be added to as the project progresses.

Charlie,
Really interesting! Thanks much for posting. Helps us "less mechanically inclined" learn a lot.

Thanks for sharing! How many miles were on this motor? I'm curious why the valves were so eroded.

I'm not sure how many miles were on it. I think water in the cylinder may have been involved in corroding/eroding the valves.

Great photo essay Charlie. Really appreciate the captions with their information and evaluation of the condition of parts - usable or not.
Thanks!
-
Fantastic photo log, that drive line sure looked tired but it looks like new now!

great pictures

Hi Charlie,
The pictures look really good, nice walk-through of the process.
Did you get the crank balanced for the new pistons, or is the 15 gram difference not enough to warrant a rebalancing?
What is the purpose of the intake reducers? Increase intake velocity?
Thanks for posting the album :)

A different piston pin brought the piston assembly up to weight.
Guzzi made the ports way too big on the early heads, the reducers are to correct that and maintain proper intake charge velocity. They run like crap without them. Been there, tried that, didn't work. :wink:
-
Ah okay, I was wondering if it wouldn't be a problem if you didn't match the weight of the old pistons.
Makes sense with the reducers if the heads have a too large bore to keep velocity up.
Thanks for clearing it up

Lots of photos added recently, getting pretty close to the end of this project.

Thanks Charlie, I enjoyed this one. Great job!

Fantastic job, and pictures, Charlie! I love to see stuff like this. What did you use as a "cushion" between the generator, and the engine case "saddle", was that a bearing shell with a hole drilled in it?
Thanks for posting this!

Aluminum sheet of the appropriate thickness, cut, drilled and curved to fit.

Nice job :thumb:
I tried the alu sheet but it desintagrated . Switched to stainless steel sheet . It has worked a treat for years.

With the generator bracket on this engine "Beefed up" let's hope the damage causing vibration is curtailed and that the erosion to the front mating surface is relieved. Time, of course, will tell.

Exactly. If vibration is destroying the aluminum shim, then parts are still moving around that shouldn't be.

Charlie, that was a beautiful build.

Thanks. Hoping to eventually make my own V700 drivetrain just as nice.

Hi Charlie, just looked through your album again, looks really nice. Well done.
Every time I see the generator arrangement I think about, how do you adjust the belt tension? Do you shim the two sides of the bottom pulley?

Yes, there are shims that go between the two halves of the bottom pulley.

I want to thank Charlie for this superb rebuild of my V700. As you all can see from his photo diary of his work that he made many improvements and his attention to tiny detail is amazing. He kept those elements that were in excellent condition and replaced and/or improved upon the parts to make this a solid stock drivetrain. On my end? Nearing the point of getting this beauty out of the basement and on to the highway. Charlie rocks!

Great stuff a usual, thanks for posting :bow: :bow: :bow:

Well she's been sitting idle in my basement for quite a while. Once in a blue moon I'd add a cable or some minor last minute detail, but hasn't been a high priority since last post. Today I muscled her up the basement stairs and to the garage. Ready to add some petrol to the tank and fire her up! Best riding season, no bugs, no sweaty helmet, just have to watch for ice later on.

Great photos ! There's something so satisfying about the before and after photos of various parts then seeing it all reassembled and knowing the end result is vastly superior to when it came off the production line.

Though, it's Charlie's thread,..it's my bike and to follow-up,..and to conclude..
After the first start up once I brought her out of my basement, the bike ran poorly and so with return to Charlie for "sorting"( I couldn't figure it out myself)

he found the new condenser to be defective, so Now,..starts easy, runs great and she's being gradually broken in back home in Southern Maryland.
Again I'm fortunate to have such a great mechanic to have helped to bring this old Gal back to life, Thanks, Charlie!

Congrats on beautyful build. Great with The reference photo album. Now get it out, break it in and enjoy it! Well earned.
I'm beefing up my dynamo bracket as well, broke it and limped 400 km back to Milan. Sounded like a hammerdrill.. But no serious damage done!
I just wondered if You (Charlie ) used a square to determine the thickness of the inlay between dynamo and block or just allowed the alu strip to wedge down with the tightening of the saddle bracket?
And thanks for the good advice on my gearbox rebuild, held up and shifted good all through Sardinia and Corsica.
Best regards
Mads

To determine the thickness needed, I use "feeler gauges" slipped in between the generator and saddle of the engine case.
