Problem, is it intake reversion?

just a little bit by hand with the rotary cutter.

after we found the 17mm pin was the same then the piston height WOW we have a match!!


a set of worn out 1015 bores honed right up

I was thinking the same thing. I think I HAVE a set of Yamaha 1100 pistons around here...I love Frankenstein motors.

You shoulda seen my last low buck Ford stroker motor, before I got out of cars.

I believe it's just the carbs. I bought a set of those from Wired George and he warned me that they do exactly that, stumble at WOT. I live with it because once it's done stumbling, I'M GONE!!!

Try some different carbs if you have them. May be easier than pulling it all apart again.

Good luck!

I would never buy a set of carbs if from someone that told me they would not work properly. After much tinkering I got it tuned out. A stumble is unacceptable to me. If that's the case while you are stumbling someone with well tuned STOCK carbs just ate your lunch!

This needs to be seen and read again
