I put cobra strights on my bike and now its poping through the pipes


it will always POP,, because you have no more back pressure and hot exhaust gases come out quicker and burn in your exhaust pipe.

Will not reach top hp exhaust cherry red


Your carb is in a lean codition which causes the exhaust to glow. I would recommend having repair shop rebuild carb .This way you get it set properly and should have to make only minor adjusments .I also recommened running a fuel stabilizer all the time .

My 2001 softail pops very load out the exhaust on decel.... but if i pull the enricher out that fixes the poping...no poping at all then....i have V&H side shots exhaust on my bike....


Your carb is jetted too lean. You can go up on the slow speed jet to the next size and try that. It's probably got a #45 jet in the carb, go to a #48 or #50.

Good Luck

03 beartraker engine pipe getting cherry red and backfiring it also is only running only at full or partial choke


You need to disassemble and clean your carburetor. Make sure the jets and carb body passageways are clean and clear. Unburned fuel from running the cycle on choke is burning in your exhaust pipe.

What would cause a 2003 yamaha raptor 350 to backfire through the carb at an idle and through the exhaust at a higher rpm? and within 5-10min the pipe turns cherry red. i have already cleaned the carb and...


Either way too lean, or air intake leak, or the cam timing is out.
Does it help with the choke on?

Not certain of the timing on that model, but at top dead centre there should be some marks on the cam sprockets that will line up with the rocker gasket surface. The previous owner may have changed the timing by a tooth or two to try for more performance .

I have cub cadet 129 with 12 hp kohler cast iron engine when it runs for about 5 minuts the muffler gets cherry red does any one know why?


This would most likely indicate an air leak in the intake tract. Another possibility would be a partially clogged main jet in the carb. Either problem results in a lean running engine with VERY high exhaust temps. Bad news if not corrected.

Hope this helps,

YAMAHA TTR 250 cherry red exhaust


Because the timing is off. If the timing is too advanced, or too retarded, it will make your exhaust pipe cherry red.
