hi, i have a problem starting my bike. it is a 93 cbr 900rri bought this bike in april of 07, it was crashed and needed a lot of work. well i finally got 97 percent of the parts to complete my project. when i try to start it the starter fires but the motor does not start it does not even crank.. is there a way to manually turn the crank to make sure that the motor is not locked up (seized)???
thanks, ron

 

If you look on the right side of your bike and just forward of the clutch cover there should be a circular cover with what I think is a 14mm bolt head on it. Use a socket to take that off and then behind there should be a bolt head attached to the crank that you can put a socket on and manually turn the engine over with.

 

If it's been sitting a while, you may want to take out the plugs and put a little bit ofliquid wrench in it overnight. Might free it up if the rings are seized. On a car you can just turn the crank by hand with a socket on the bottom crank pulley. Not sure if you can do that on a bike, but if you do, take the plugs out first.

 

hey,
thanks for the info. i will definatly try to find the bolt to turn it over. i will also try to put some liquid wrench in, i know that the bike was sitting for quite awhile.

 

Ty, thats what I'm referring to on the bike, its a bolt head that turns the crank instead of a pully. You can turn it over without taking out the plugs but it will be a lot easier to turn over with them out. If you suspect the engine is siezed, Ty's advice is good.

Here's a pic of what I'm talking about. Remove the cover the arrow is pointing to. then turn the bolt head underneath with a socket to turn the crank.

Cool, never tried it on a bike before, figured it had to be fairly similar. Good pic.

Ron, don't be scared to put some weight behind it ifat first itwon't budge.

 

WOW! thats great thanks alot for the picture it helps alot. and don't worry about me putting my weight into it ,i'm not known for my finesse i'm a bit of a bull. worst case sinareo what do you think it would cost to have the motor re-built? any idea? thanks again, ron
