SP2 with Smoking Habit
Hello all, new member first post.
I've done a search within the forums for a similar problem but it revealed no results. I have an '03 SP2 with the PAIR and flapper mods done, full Yosh system, and 4800 KMs (Canadian, sorry metric sysytem). I've put very few miles on the bike this season with the full system (fist season with the exhaust) without a Power Commander, it was running lean but the temps stayed low, but it started burning oil. It smokes under idle only, once it has reached operating temperature. It will smoke slowly under idle, but when you blip the throttle quite a bit of smoke will blow out, if you continue to twist the throttle the smoke dissipates. I've had the bike serviced and the techs are stumped. The problem has been narrowed to the rear cylinder (as theres no residue on the front cylinder),rear exhaust valve guide and seal replaced and machined, rear cylinder piston rings replaced, cylinder honed, and abreviated break in done...and it STILL SMOKES!
I'm mechanically inclined and have ruled out a number of possibilities, as have the technicians who have worked on the bike, but I'm at a complete loss.
If anyone has had a similar experience, I'd very much like to hear from them.
Thanks in advance.
