I have power loss and a red hot glowing exhaust pipe on my 2006 Triumph Scrambler (only the top pipe). I'm bright enough to know that's bad, not new enough to have little to no idea my it happened. It's my first bike and I've had it just over a year. Here's the tale: - nice ride of Thursday afternoon and stopped for gas part way along. Made the noob mistake of buying the ethanol blend - everything was running sweet and about 70 km later we got near our destination and stopped to check a map for the last short stretch - after checking the directions I had a bit of trouble turning it over and once it was running the power was way low and things got louder - only had about 2 km to go so I powered through. Let her cool down for about 20-30 minutes and decided it may be the ethanol blend causing carb issues. - got rolling again and rode about 4 km to Canadian tire with the bike seeming to run better. Bought a gas can and siphon and replaced the ethanol blend with premium. - started heading home and everything seemed good again, but about 60-70 km into the ride there was a sudden power loss again. - at this point it was late, cold and we had 60 km to go so I had to limp it home and it got to the point that the top exhaust pipe was literally glowing red hot. I stopped repeatedly to let it cool off a bit and managed to get it home. It's at the shop this morning and I thought I'd see what you guys thought so I don't get taken for a ride. Based on my description the guy at the shop (without looking at it yet) said probably the worst case scenario is a blown ring that would probably end up in the neighborhood of $2000 to fix. Any thoughts on what the problem may be? I'll update the post once the shop has had a look and gives me their theory. No word from the shop, but here is a pic for your viewing pleasure: Thanks for all the tips folks! Awesome how quick people respond to this kind of thing. The gas was 10% ethanol and 89 octane if that helps. A muffler fault sounds good to me in this case. The fella I bought the bike from sold it with two extra sets of pipes (Triumph TORS and Thunderbike pipes). I put the stock ones on so I didn't piss of the neighbors in my townhouse block. Still no word from the garage though. They looked pretty busy pulling bikes from storage when I dropped mine off so I guess I'll cut them some slack on that.
