Hi Ed,

I assume you are currently running the stock Keihin carb.

Have you purchased a flat side carb yet?

Make sure you get a Mikuni TM28ss carb, from a Suzuki RM80, this is what works the best on CR80’s.

Don’t know what altitude or what air filter configuration you are running. I run a K&N style filter at about 1,000 ft above sea level, running 37.5 pilot jet, 195 main jet. This should get you in the ballpark as far as jetting goes.

CR80’s do not like to be rich, if they are too rich, when backing off the throttle after a long straight it will bog when you hit the gas coming out of corners.

Hope this helps
