hi i got a 86 lt250 and im trying to get a micuni carb rebuilt.can anyone tell me what size main jet should be in it?.ive got a 42 in it and a friend told me he thought it was to small.
thanks

 

I have an 86 lt250r and on the stock card I had a 190 main with an K&N and FMF fatty. Try a search in these forums. I found a ton of info on 250r jetting for our bikes.

i dont know if that is my trouble or not,the bike runs good,it idles pretty good but has no power.any suggestions would be appreciated.

 

Well if you have a 42 main in there. I would change that in a hurry.
