There was a thread on the old board (I think) about someone looking for the champion plugs and a discussion ensued about which is best. Might be worth reading. My RS uses the A55V, which are the surface discharge plugs. I couldn't stop them from fouling and switched to Denso Iridium race plugs, which work very well for me. It's certainly worth checking the plugs to make sure the are soiund and have a proper gap, as Shazaam suggests. But, I remain skeptical about that being your problem, Chillo. My advise, as others, bring it to John Hackett. He is THE expert. If he can't sort, you need to get a replacement bike. |
