Default Front sprocket

So I'll hide it down here in the Saloon, where you guys won't make me look too silly.

That front drive sprocket nut; it's not a left hand thread is it?

Tried to get mine off tonight and it was just not playing nice.

Before I break anything, I thought I'd just check.

Maybe I just need to bring a bigger gun to the party and buy a 14mm 1/2" drive socket?

I'm thinking that it's probably the first time it's been off in 26 years, and is actually quite attached to where it lives??

As I recall it's a standard right hand thread.
Put the bike in gear and use enough spanner Teeks
(They do get tight after awhile though - mine was too)

Wait till you see how much muck has collected down there in 26 years...........Mmmmmmm

No hiding in the Saloon, Teeks. LoL

A bit of CRC for an overnight soak; new 14mm socket and a borrowed 400mm power bar.



And it just made that delightful click, that tells you it's actually coming undone (and not snapping off deep in the output shaft, what the hell would you do if that happened???)


So; lesson learned. Subscribe to the Zen Theory of Motorcycle Maintenance; not everything has to be done in your time frame, sometimes you just have to wait until the motorcycle decides that the time is right.

TK, I can't believe you haven't needed a front sprocket in 26 years!

A lifetime average of about 800 miles a year, it does take a little bit of time to wear out a chain and sprockets at that rate.
