Hey, this is my first post on this forum,I would appreciate any advice on a "problem" that I'm having with my bike('03fxstsi) I have found some similar problems on this forum already
but would still like some input. My Samson pipes are glowing orange. I probably would have never noticed but I ride my bike into work on the freeway at 2:00 in the morning.
I just had it on the dyno again for this problem.I've had a few people tell me that this means that it is running too lean and that I'm gonna fry my valves,heads,pistons,etc.
the AFM is almost a perfectly straight line all the way across that runs between 13 and 14. The pipes are still glowing but the bike runs great. I am scared to ride it because I don't
have the money for a new top end of my motor. I have a SE air cleaner and Samson "rip saws"(no baffles) and a power commander111r. If I put the baffles in it without re-tuning it,
that should richen it up,right? I can also change the mixture manually on the power commander but the last dyno tune got me to 68h.p. and 78lbs. of
at 4300r.p.m. with a
A/F ratio that I've been told is right on the money. So the bottom line is that I don't want to %#*&@ with it if there isn't a problem. I just wanna ride. [:@]

 

If your AF #s are correct than Id recheck your timing.Glowing pipe with no restriction isnt good.

 

I would put tha baffles in and see what happens. You need backpressure to run right. Do you have any exhause gasket leaks?

 

Thanks for the response,I'll check out the timing and see if the baffles make a difference.
