Well, when im riding along i hear an awful grinding noise coming from the area of the front sprocket. The faster i go the louder it gets, above 40mph its howling like a beast lol.
This did not come on suddenly, its been like that forever. If i loosen my chain it eases the problem and you cant really hear the noise so much, but then the chain is loose.
I think maybe the bearing on the front sprocket is shot, what do you guys think?
Cheers

Possible... but more likely, the chain is toast. A shot chain will make a grinding noise, too... and unless you've been running your chain too tight, far more likely.

counter shaft bearings known to go out on these things

i had a brand new chain and sprockets fitted last week, and ive only been out on it twice. The first time the chain was real slack and i didnt hear the noise really, and then i tightened the chain to correct tightness and went out again and the noise was loud again.
So the noise gets louder if you tighten the chain, is this a symptom of the counter shaft bearing being out? And where can i get a new one of these?
What is a counter shaft anyway :duh:
thanks for your help guys appreciate any replies

If the counter shaft bearing is causing misalignment can i just tighten the chain tensioner more on one side than on the other to pull the chain back into line?
Anyone know where i can get a new counter shaft bearing? :duh:

countershaft bearing is the main transmision bearing behind the front sprocket requires the bottom end of the motor to be rebuilt and a new bearing if available be pressed on better of to get a good used shaft but look for anything else it could be first

well i adjusted my chain and loosened it a slight bit, now the grinding has stopped but theres a whining whirring sort of noise which isnt that loud. Im not sure if its normal transmission whine or not cos i dont know what the normal sound would be. Do any of your b4's have transmission whine or are they quiet in that department?
-
My Bandit makes all kinds of noises....its hard to tell which are normal and which are bad! :duh: :lol:
Actually, I had a weird grinding noise too, after I removed both wheels, painted them and put them back on. I thought maybe something wasnt greased properly. Turns out my chains was way too tight, so I loosened it, also gave it a good cleaning and lubing. Now its nice and smooth! :D
-
yes they can have trans whine
-
ok well going from those two posts i think ill not be too worried, ill just make sure the chain aint too tight and not worry about the transmission whine
thanks guys
