Hey everyone, I'm new here, love my 2004 P3 but it makes a variety of noises that I'm pretty sure shouldn't be there. I just changed the drive sprocket and belt because under a light - heavy take off load, there is a squeal/squeak. It almost like a squealing tire sound.
The next problem is a lot of pops that come out of the exhaust pipe during deceleration. someone mentioned it being a typical v-h characteristic but I don't know what that means
I think this next one might be my primary chain tension but I want to be sure. When I'm stopped, and letting the clutch out, there is a rapid series of snaps that come out of the left side, and the bikes acceleration is a little jerky.
There questions may have been addressed before, but anything you guys can tell me, I would greatly appreciate it!

So you changed the drive sprocket and belt because of the squealing noise. Does it still make the noise?
Maybe check/adjust rear shock preload to ensure there is nothing rubbing the belt?
Exhaust burbling/popping can happen for two main reasons: One the bike is running overly rich and the hot exhaust header ignites unburned fuel and/or the exhaust gasket between header and cylinder head exhaust port is leaking allowing the same to occur for even a normal air/fuel mixture. An aftermarket exhaust can definitely exhibit the popping/burbling under decelleration.
I think you are accurate in your assessment of the need for a primary chain tension adjustment. |

The Blast has no rear pre-load adjustment.
I had a blast for 8,000 miles. Never heard of anybody having a squeeling noise like that. You need to go to the Thumper forum and take to EZ and ErikO.
The V&H will cause decel popping if you do not re-jet your carb because it flows so much better than the stocker. The proper jetting for that mod is listed in the Thumper area.
I agree too that it sounds like your primary chain is WAY out of whack. I wouldn't doubt if this is also the cause of your "squeeling" thing even if it doesn't seem to be coming from the same place. Do not ride it like that. You should definatly pull the primary case and inspect for damage. If there is none, then make the proper adjustment. With that kind of description, I'd guess your adjuster shoe is toast and there may be other problems too. |

Yes, after the new belt and sprocket, it still squeels. I'm not sure where the squeel is coming from, I originally thought clutch, but then moved to the drive belt because it has 8000miles on it and its possible its the original belt. I never made any performance mods, and I believe the carb hasn't been jetted, but I can't be sure. |

8000 miles is nothing for the belt. They are good for 20,000 at least - people have gotten double that out of them.
Like I said, I suggest you get the bike fixed before you ride it anymore. |

Welcome to Badweb!
It almost like a squealing tire sound.
Are you sure it isn't a squealing tire? It's very easy to spin the rear of the Blast when pulling out, particularly when the tires are cold.
lot of pops that come out of the exhaust pipe during deceleration.
Mine does that, even with the stock exhaust. I think it's normal.
I think this next one might be my primary chain tension but I want to be sure.
The easiest way to tell is to adjust the primary chain tension and see if the problem goes away. It is fairly easy to adjust. There are instructions for doing it w/o a torque wrench floating around here somewhere. If you dig around you should be able to find it.
here is a rapid series of snaps that come out of the left side, and the bikes acceleration is a little jerky.
Perhaps your clutch is slipping?
There are 3 adjustments which affect the clutch. Primary chain tension, clutch cable, and ball ramp. They are all easy to do, and if you have an inclination to fix this yourself, you might as well go ahead and do them. It will take you 15 minutes. |

Well, my belt saw some bad times, the sproket was bent from the previous owner running over a curb or something. Im going to try to eliminate the tire squeel by jacking the rear wheel off the ground and holding on the rear brake while trying to accel. I adjusted the chain tensioner, it took out a good bit of noise but I didn't have a torque wrench and didn't want to over tighten it.
Thanks guys!
