have a LT250R '88. The stock main jet is 240. I have a FMF pipe, bored .030. I recently bought, a 250,260,270,280, and a 290 jet. I dont know what to put in it. It is about 30-40 degrees here. THANX
The clmer manuel says a 250 jet for the temp, but i dont know to configure the exhaust and the bore size.
