? flywheel nut. See updated torque specs. | ||

How many miles are on the bike? The primary chain tends to go overly slack during the first few thousand miles and settles in sometime after that. Easy enough to check through the smaller inspection hole. Check the easy stuff first. | ||

okay Question. Is this going to be a warranted item? I mena the torque specs? I can't do this myself and will I have to pay the dealership the labor costs? I am jsut curious, thanks. Jerry W Des Moines, IA | ||

Yeah... I'd check the primary chain yourself before you take it in. IT's real easy. You just need an allen wrench of the right size (it goes in the bolt under the center of the primary), a crescent wrench and a T27 torx head (should have come in your tool pouch). Open the small inspection cover when the bike is cold and check the chain for tension. I like about 1/2". Too loose is WAY better than too tight. You can put the bike in neutral and bump the starter a few times in order to check a few spots on the chain. You want to try to find the tight spot and adjust there. As far as actually adjusting... Loosen the nut under the center of the primary with the crescent, put the allen in the bolt and turn the allen until you get the desired tension. Once you have that, tighten the nut back down while holding the bolt in place with the allen (otherwise it'll tighten the chain just a bit on you). It's really easy.... | ||

If it's the sprocket that has come loose it should be covered.. | ||

its the compensation nut coming loose. i almost bet anything! If that is the case, stop riding/starting the bike. You may just kill it. Look here! | ||

I have a noise I want to describe to see if someone may know what it may be. It’s a knocking or clicking sound coming from the top, right, front cylinder, possibly the gear case but it sounds higher than that. I’ve had the mechanics listen to it, but of course they had no answers. If you have experienced this please let me know what you discovered. The mechanic used a stethoscope and the only thing I remember is he ruled out the bottom end. He said to just ride it. The primary chain was adjusted about 1,000 miles ago and I checked it 100 miles ago, still have the noise. It does not change when I load the engine. Thanks | ||

Cowtown, Stock exhaust? Does the sound change at different RPM? It is probably valve train chatter. Is it most pronounced at 2700- 3000 RPM with the engine floating ( not under load just cruising)? I use a mechanics stethoscope and check the four lifters by putting it on the allen head bolts that hold the plastic push rod tubes in place. They should all sound the same, very noisy, but uniform noisy. | ||

I have a Drummer. It’s seems loudest at idle. | ||

Well it was my flywheel sprocket nut that had come loose. Luckily no damage, they just tightened it to the new torque specs. | ||

I've got an '03, well out of warranty and experiencing the same knocking type noise for quite a few miles now. I've got almost 11k miles on the bike. Is the compensator nut torque update a recall type update, or am I going to get stuck paying for the dealership to take a look at it and fix it? | ||
| Cowtown |
It’s not a recall. I’ve heard that if they find it loose, they will torque it at no charge. But if it’s not loose, then yeah you’ll have to pay them for their time. | ||

OK. Thanks. I wish there were others around my area with Buells. The knocking isn't that awful loud, and I think it may be just normal engine noise, but I'm not for certain. I don't really trust the local dealer here, and don't want to get milked of the money it would cost to have them check it out. My noise seems to get a little more pronounced when the bike warms up. |
