So I installed a 14 tooth front sprocket over the weekend, and when I got everything back together, the bike didn't ride right at all. There was a TON of vibration in the footpegs. I know the engine runs at higher RPMs at any given speed, but I'm not talking about that (and it should be marginal with only a 1 tooth difference, anyway, right?). I'm talking about intense vibrations anywhere from 4-8K (didn't go any higher than that) that seemed to be coming from somewhere around the back wheel. Also, when I pull in the clutch at speed (40+), the bike makes this crazy loud whining noise.... Any suggestions? I took it back home and checked everything out. Thought maybe I had tightened the rear axle nut too much, so I backed it off 2 holes. That seemed to help a little, but its still a lot louder than normal. The castle nut is still pretty tight, but I don't have a torque wrench to check it. For that matter, I don't even have a clue what its supposed to be tightened to anyway. Anybody know? I put the front sprocket on with an impact wrench and pretty much let it go until it wasn't tightening up anymore. Other stuff that might be relevant: When I replaced the rear caliper, I tightened those bolts TIGHT... pretty much as tight as I could get them, b/c it looked like there was some loctite on 'em when they came out the first time. Anyway, as soon as I noticed the vibrations, I pulled over and checked everything out. The rear disc was HOT, probably 2-3x as hot as the fronts, and I didn't even use it at all from what I remember. Funny thing is, the bike didn't seem to try to slow down any more than normal when I pulled in the clutch, so I'm can't imagine the rear pads are rubbing (plenty of pad left too...). Another thing: when I took the rear axle out, the spacer from between the wheel and the caliper bracket came out and landed on the garage floor... I checked it out pretty quick before I stuck it back it, and it looked fine. There was a little dirt on it, but I didn't wipe it all off b/c I didn't have any grease to re-coat it. Think it may have been a little too dirty, and thats where the noise is coming from? Crazy, i guess, but I'm just trying to cover all the bases. Unrelated, but the stock front sprocket had a little bit of oil on the back of it when I pulled it out too...Normal? Chain slack seems alright, maybe just a hair too tight, but it still slacks at least an inch. I could just be fooling myself on all this since I wasn't too sure about changing the sprocket myself, but it seemed pretty straightforward. Any suggestions?
Oh yeah, I dropped my bike for the first time last night too. [V] Just fell right over on the asphalt. No frame sliders, either. Nothing got broken, but it definitely put some scratches in my nice green paint, damnit.
