Shouldn't be too hard. Dunno bout the GSXR but the R6 it was fairly simple. Take off bolt, replace sprocket, replace bolt. Just make friends with someone with a impact gun cause that bish is on there tight.

yes, impact gun is the best way...if you don't have one....it's a pain in the .

if you're ever in the northside, bring it by my shop, and i'll help you put it on....fo freezy.

if you're gonna do it yourself, take the sprocket cover off (usually 2 or 3 bolts)....and there will be one screw holding down your front sprocket....find a way to keep the rear wheel from spinning and loosen the bolt....replace sprocket, replace bolt....your done.

You'll probably need to loosen the rear axle and slide the rear wheel forward slightly to put some slack in the chain.

If you don't feel comfortable doing it yourself Dean you can come by my house this weekend and we'll get it done in about 20 minutes.

I just did this 3 weeks ago.
I learned the hard way. Keep the chain and rear wheel on. Have someone hold the rear wheel (not ur GF either).
Get a breaker bar and crank away. Took a lot of effort with a little bit of fear. That sucker is on tight!!!
Next time im going to someone who has an impact wrench...

Don't take the wheel and chain off just yet. Use a 2X4 and jam the wheel spoke to the swing arm. Take the cover off, don't lose the long pin, use the allen wrench to loosen the lock bolt. Use the socket to take the nut off (Use cheater bar if it's too tight). Pry the sprocket off... the rest is easy. You do change the rear sprocket and chain too, right?

u need to change the rear sprocket front and chain all at once. or all the parts u put on will make the old ones where out faster and be a waste of money.

Like others said, leave the chain on. 2x4 through rear wheel spokes works, but having someone stand on the rear brake pedal is just as good without risking scratching things up. I would not do this with the bike in gear.

Cheater plus a large friend is all you need. (that didn't sound right) You can buy a hammer driven impact wrench to tap the front sprocket nut loose.

I'm gonna have to call myself a dumbass on this one. After some research, there is potential to mess up some transmission parts while removing the front sprocket nut with the bike in gear.

Ive got an 06 gsxr 600 and I did the -1 front sprocket change about a month ago.. it's simple! took me about 30 min. I also put a speedo healer on it, my speedo was off about 12.5% no changes to the rear, stock chain.. im happy.
