Will PreGen fork tube fit NextGen lower??
Just picked up a 96 and 09 donor bikes. The 09 is destined to be re-engined with a RD400F motor, with about 70+hp.

Having seen what you have accomplished, well done.
My guess is the "gunk" under the valves was the culprit.

I swapped, but the other way
I went the other way.
I traded sides on all the pedal bikes I have owned. It's an easy swap and the levers/perches don't care that they are both "upside down".
Drove me nuts to grab a big handful...

Squidly does not understand physics...
Squidly was doomed from the beginning. There was no way he stood a chance. It was over before it started.
A 60 c.i. short throw engine can't develop the torque the the 100 c.i. long throw can.

More info from inside...
Yep, you got a mess, but not necessarily a done motor. I looks like you still had lots of coolant left inside. Any left is always better than none.
Is there any coolant in the oil? If there is, it...

Really cheap...
I don't time on track days. That's for checking gearing, etc.
If you really need to know, take a buddy with you: pencil, clipboard and watch. It helps them get into the action.

With a 100 psi start and a 25% drop in diff pressure, the air should be audible somewhere. Set the tester up again and hold a smoke up in front of the carb inlet then the exhaust outlet. See the...

Thanks for the info.
How many miles? Do you have access to a smoke generator tester?
