Hi, thanks to the help of some of the guys on the forum I have placed a clunking in the engine to a need to de-coke it. I've stripped it all down and indeed it needed some work! All done now and ready to go back on. The problem is seating the cylinder over the 2 piston rings. I'm sure their is a tool for this to squeeze them in, but any tricks to make it easy??!

Thanks

Alan

It really should be quite easy make sure you have the rings in the correct place with locating pin in the gap

have the piston at BDC you should be able too get the barrel over the first one then check the second ones position squeeze with finger and thumb and barrel on?

I assume here that you took the rings off the piston and cleaned all the crap out from the ring slots?

Thanks for the reply- I did clen it all out but as I squeeze them together they want to spring back and hard to slide on. I will try BDC and take rings off to clean all crap out completely.

I was thinking of a big fat zip tie around them. As you slide barrel down it would slide on and you could just nip the ties off?

Hi mil,

Check out page 27 of the following top end maintenance manual from Sherco for one possible way of doing it (be patient as the manual is something like 1.5 megs and may take a little while to load):

Good luck,

Thanks for the help Brian.

Got it all buttoned up today- the problem was that I hadn't located the rings with the split either side of the small 'notch' in the groove. This stopped them compressing completely. I only realised this when I took the rings off and cleaned the grooves out etc...!The only problem now is getting one of the manifold bolts in as you need a ball ended allen key as the header pipe runs right over the top of it! Keeps wanting to cross thread but I'll get there.

Cheers fellas for the help. But snow for 3 days solid here means it'll stay in the garage for a while!!

should be able (just) too start that one off with your fingers, can't remember exactley how I did mine but may of been that I started with that one first? just too start it?

Then as you say a ball ended allen key is essential
