problems in gaining access to the primary sprocket on my 500K2
« on: November 27, 2006, 11:27:08 PM »
I am having a hell of a tough time getting the side cases off so I can get to the front sprocket. I need to change out my chain, and the bolts are not cooperating. I am afraid that if push it, I might end up stripping the heads. Short of buyinga set of impact tools, how can I get past this problem?

I swear by PB Blaster. Think of it as WD40 on steroids. This stuff breaks loose just about ANYTHING!!


Here's what I'd do:
1) PB Blaster
2) Impact driver (attach a socket and hit the other end with a hammer)
3) remove the bolt
4) be happy

Agree.

Impact driver should be the first tool in any SOHC toolbox!

The only ANSWER  is an Impact driver

You definitely want to be able to get your covers off, so put an impact driver on your holiday list!

But, if you are desperate to get the new chain on NOW, you can simply pull the master link off your old chain, connect the new chain to it, then thread the new chain over the drive sprocket by pulling it through with the old chain.
Can I have a motorcycle when I get old enough?
If you take care of it.
What do you have to do?
Lot’s of things. You’ve been watching me.
Will you show me all of them?
Sure.
Is it hard?
Not if you have the right attitudes. It’s having the right attitudes that’s hard.
