i bought my 89 lt from a buddy who said it had some electric problems, after taking it out i figured out there were wires arcing on the frame fixed that then found it was runnin very lean with a 190 did a few plug chops and now i have a 260 in it, still a lil lean but better and thats with stock pipe, dg silencer and and uni air filter but i keep up with my buddys 03 shee till around 5th

a 240 main is what they come with stock in 88. you would be crazy to run a 190. say goodbuy to your top end. for some reson they changed the jetting on the lt250's allmost every year. have a look at the jetting by year section in this pdf manual.

in 91 they had a 270 and 92 a 260. pilot jet changes were made as well.
