Stimied a bit by pistons. I bought a new Gilardoni nikasil kit that was supposedly applicable to the 93 1000S, but it came with lower-compression pistons a la the 30mm-carb, small-valve square and round-fin 949 motors. The 93 1000S and Cal III and SP III had 36mm carbs and mid-sized valves.



No one seems to be able to source the mid-domed slugs, so I will be re-using the ones that came out of the bike after 92,000 miles, with new rings and new nicasil cylinders. I don't want to dull the thing down, and in fact have swapped the OEM cam with a B-10.

Otherwise it's coming along. Frame is welded back together, forks and wheels are done, trans is back from Charley, and Mike Rich has the heads.

F_Sahms I think I know what you are saying here about the crown being shorter and different than the previous factory part but what about the wrist pin location? If that is moved at all then they could have "done the math" to create the same or different compression ratios. Maybe the crown of the piston was changed to enhance combustion or something...just sayin'

I wish. The pin-to-ring and pin-to-flat-top dimensions are the same, so the lower-dome pistons would give lower compression ratio. The pistons in the kit are identical to G5, SP1000, Cal II, etc. slugs.

Right on, just thought I would point it out. Never know if someone is knows these things. If you speak good Italian you could call and ask why
Good luck with the build bro!

Dead Right There

I'm done until further notice. The tranny munched itself in the first 2000 miles.


It was the only unit I didn't rebuild...

So as I seem to be getting to grips with the problems on my Guzzi, and the list of things to do gets ever smaller My thoughts turn to improving things a little... I know, I know! I can hear you telling me to leave it alone from here



Now, one of the things that needs, or could use improving is the front suspension, it makes quite a clunk when you hit a pot hole or drain cover, also it is not the most stable bike I have ridden? and tracks with the road surface. So back when I pulled the forks apart to replace the bushes, I was surprised at how similar they were to BSA forks, in fact they are almost identical to those fitted to the A10 and M33/B33 range of bikes. Well this got me to thinking, back when I had my M33 I had the same issue with the front suspension, and I overcame the problem by fitting BSA Goldstar damper rods inside the fork stanchions. So I am going to do the same on the Guzzi, this is not a big job on any of these bikes, as they just screw into the fork top nut, and hang down inside the stanchion.

You can see the damper rods here...

Very interesting! Please post details when you do this, lots of other Loopers would be interested in doing the same. Looks quite simple - something I could whip up on the lathe in no time.

DaneDG....

Real sorry to hear about the tranny going south. Did it make horrible noises, or just go into some neutral stage?When you decide what you're gonna do, would appreciate you posting about it.

I'm debugging my T3 now, I'm actually surprised a bit by how rough it seems to ride, the mirrors vibrate pretty badly, and I don't have it tuned well enough to feel confident going very far. And the clutch isn't engaging very well, cable needs replacing. Plus it gets hotter than I expected. I may end up wanting an airhead next...

not to stomp on the guzzi thread at all but I think that a lot of Guzzi riders have airheads as well! LOVE THEM BOTH!

It just sort of quietly let loose, didn't lock up and I can't shift it. It is in "the Neutral Zone"... with lots of shavings on the magnetic plug.
It's out of the bike already and I'm ready to start taking some pics...

Hey danedg, I'm sure you already know this but there are special tools used to disassemble our Guzzi trannys. When you decide to have it fixed you can pull it from the bike and send it to Charles Cole in NY. He does most of them and is SUPER knowledgeable on this subject as well as the rear drives...If you need contact info. just let me know.
