It's on my list of things to do. This week is finishing getting the carb sorted and replacing the 25 year old worn out shocks with some Progressive 422s. Harley handgrips are driving me nuts with the cheap chrome plastic rattling around so changing out those. Probably do gearing this coming winter.

 

Other thing I was thinking of is to convert to 6 speed this winter so good time to get the hearing sorted out.

 

So I think the .76 main and .31 intermediate was the ticket. At high RPM this bike is screaming. The only time I was able to get it to stutter was cruising in high gear and then going full throttle without downshifting.

 

Glad to hear.. be safe...

 

Back to the drawing board. Still cutting out. Now it started happening under acceleration from slow speed. Judging by black smoke when choking I am way to rich. Bought a rebuild kit for the carb, new backing plate as the old ones mounting tab was broke at the breather bolt. Also ordered a conversion kit to convert older style rebreather system to new style. Any other suggestions?

 

Do a compression test.
A healthy 80" will give you something like 160 psi.
If you have something bigger you will get something like 180 or 200ish psi.
If you have to run a 31 and 76 on an 80" motor then you are masking another problem.
Not sure what it is but no 80" needs a 31 or 76 to run correctly.

 

Yeah I don't think the jets helped. Gonna pop the original jets back in or even the leaner ones you originally suggested. Give the carb a good cleaning and change out all the gaskets. Will try to borrow gauge to do compression check. Could an intake leak possibly cause it?

 

Easy enough to check without buying parts or going through the effort of installing the parts only to find that they didn't fix your problem.
