Hi All,
Recently bought a very nice '75 850T with 22k miles. Sat a lot, and I knew about the chrome barrels issue, and lo-and-behold, the left side is flaking at the very top of the jug, above where the top ring lands. I pulled the sump and screen, everything was clear. Next, I'll pull the rods and check for damage on the shells. I very much do not want to pull the crank. If the rod shells/crank is damage free, I may just deal with the top end, and run it. (I'm hoping that the chrome bits exited out the exhaust)
I have a lead on a 1000 top end with iron bores. I'm considering it over the Gilardoni kit. I hear the heavier 88mm pistons may introduce vibration. I've also heard that the 88mm pistons can be lightened to be close to the weight of 850 pistons. Has anyone done this? ( I know I'll have to turn down the spigots on the jugs to fit the block) (or I could run the entire engine)
I have a fair amount of experience with airheads and some home-garage balancing on the top ends.
Thoughts?
Thanks
