A few CR250 questions
I have a 91 CR250 and just got a Clymer manual for it. It says runs a BR8EG, and I have been running br8es plugs, does it really Matter that much? Also been running 40:1 and it is recommending 20:1 which sounds way to rich to me. Last thing is it says run 1040 and I was told at the bike shop to run 80 weight. So what is better what I have been doing or what the clymer manual say?
