Can be an air leak in the exhaust. Check with a candle around the header and muffler connections.
Quote:For example, the bike died on the road once when slowing down from 50 to turn off the highway, and once more when coming to a stop at a red light. (Also coming from going about 50). I figured I might have messed up shifting the first time, as I had no problem starting back up again. And the second time proved troublesome so I switched to reserve at which point she started and got me home (another 15 minutes on the freeway).
Can be a low idle speed setting, adjust it up a little.
Quote:Over the next few weeks, I took her out twice to experience some heightened backfiring, sputtering, loss of power, and even a couple of shut offs while on the freeway. Some light research on the forum led me to believe the petc0ck was at fault. I pulled the vacuum hose to find it had ripped on the carb end… I thought I found my answer, but even after trimming it and retightening I was experiencing the same issues :'( Next step, prime & cap. After setting to prime and capping/clamping the hose shut I could barely go around my neighborhood before the engine failed in a flurry of backfires.
Most likely petcock and/or vacuum hose. the petcock is 10 years old and that's when they go bad.
Quote:In her current state, she runs fine cold, no backfires, no stuttering. But as soon as she warms up, I can’t even turn the throttle a quarter of the way before the engine cuts out and won’t start up again. I’m forced to wait ~10 minutes for her to cool down enough to start back up.
Try not to run it too long at a standstill and put a block under the sidestand so it's nearly vertical. Otherwise to starve half the cam for oil. Sometimes a piece of 2x4 is good sometimes you need a little more. You want it tall enough to minimize the lean, but not so much that the wind will blow it over. You can use the block while you're checking the oil too.
I've got a 2008 that is experiencing weird symptons. It will only run properly with the petcock on reserve. What goes bad in this assembly, anyway? Easier to replace entire unit? How to access the unit? It began acting up last fall before I put it away. Thank you!
