I have a 1990 GSXR1100. Anyone got any tips on removing the front sprocket nut? Mine is REALLY tight and so just thought I'd ask b4 I take the grinder to it :cursing - or any tips for grinding the nut off :scared

Mark, If you havent taken off your chain already, you can put a piece of wood(2x4)through the rear wheel spokes and run the wheel around so the wood is agianst the swingarm. To remove the nut the wood should be agianst the top of the arm. Then put the bike in gear and tourque on the nut. The nut usually has like 80lbs of tourqe on it if I remember correctly. Good Luck
Good tip - I'll give it a try. Thank you.
Use an impact driver. Much better than grinding it.

Tried that!:)
. . . although I should give the impact driver another bash . . . the one I had self-destructed. I'll get one from work.

I won't damage anything by bashing it will I?
unless the previous owner f-upped, it should easily come off with a breaker bar with the chain in place. you can have someone else use the rear brake.

Put the bike in neutral and hold the sprocket with the rear brake. If you leave it in gear, you're hammering on the gear faces with that impact wrench - not good.

Otherwise, it should work fine.

Thanks for the tips guys. I did try a ~4 foot breaking bar to no avail (believe it or not)

No great rush tho' - I have gotten used to heady acceleration and high revs :biggrin ( I am down 2 teeth on front sprocket - previous owner)
Sounds like he used the wrong Locktite.....may have to use heat:sad. What does -2 equal for you?
:eek:hmy HEAT! - I think I'd prefer to grind it off, knowing me I'll set the bike on fire or at least cook any seals in the area.

Sorry Ragnar - you lost me there. Waddaya mean?
Haaaa....yeah you would have to be careful.....I replaced the countershaft seal while I was in there anyway......

.....Oh, I was just wondering how many teeth you had left:p
Lol - unlucky 13 at last count
Ahh, if your not Catholic (or a Knight Templar!) your fine........I'm running 13 too:D. Works well on a 1052, if yours is an 1127 it's pretty steep......different tranny ratio.
