I'm working on a an old blast that probably hasn't been run in at least 10 years. It has just under 3500mi on it. I've cleaned the carb with solution and a sonic cleaner. Modified the auto choke to a manual configuration. Any time the throttle is bliped, the bike stops running and exhaust is backfired through the carb. Best chance of hearing it wind up is when it is cold, but typically as soon as you left off it dies and backfire. Any recommendations would be appreciated! |

Here are some video links of it This was after it was warm and quit on me several times, you'll hear it hang before RPMs finally increase. Two seconds later the 2nd video happened when I gave it throttle. Which is what seems to happen when it warms up, it dies, or usually it also backfires through the carbs when it dies. https://www.dropbox.com/s/yjucd1tss59l6bz/2017-08- 03%2009.08.21.mp4?dl=0 https://www.dropbox.com/s/1v5rywss2q5sg5u/2017-08- 03%2009.09.36.mp4?dl=0 (Message edited by marc85 on August 03, 2017) |

Rubber intake manifolds dry rot and crack. Causes this lean bogging condition. If carb is otherwise working well I made a new one out of gas tank filler hose of the correct size. |
