Ok I have an 86 250r it has LRD adjustable pipe LRD silencer, Boyseen RAD valve air box eliminator with K&N stock carb reed spacer, think its like .020-.040, (been awhile),shaved head with around 190-200 compression if I remember correctly run Amsoil Dominator 32:1 w 93octane. -1 Roll Design swingarm no link, It seems to run in my head I have 158 jet in there, it starts good idles great even seems to have the low end chug to get thru tight trails. When I first start start it and run it for a few seems to really throw thr blue smoke but unless I really really try its hard to pull the front wheels, and in trails sometimes really needed. And with thr -1 swing I would think it would be easier yet. Seems like my jetting is off somewhere what are suggestions if any, thanks everyone

you might try asking over on 250r.org .clutch slipping could cause your problem.

What gears are you running? What size tires? Do you have any port work? Has it always ran like this?
