KR-1S.co.uk Forum

a few of you may remember my quest to find a "basket case" to restore but as that seach wasn't yielding many results I ended up doing a deal with a breaker on this KR1S



It needs a few bits and bobs doing but I'll be happy just to get out on it.

Looks great,green wheels are the way to go.

My favourite colour 1S.
Enjoy .

That looks good, certainly too good to break, or did he just have the bike to sell as a whole?

the guy i bought it off bought it in to sell on.

unfortunately my "new bike" happiness has been taken a battering as whilst warming the KR1S up this morning, the engine developed a very nasty rattle. stopped and appears to have shat itself

I'll strip it next weekend and see how bad the damage is. How much is a piston kit?

Yep, but that is the beauty of owning an old stroker

I effing hate these Kr1s at times bloody things!
Nothing but trouble, expensive bloody trouble..........

But then, when its all working sweetly & the sun is out & the bike clings to the road & handles like nothing else, not even modern tackle.........

You remember why you bought one.

Wouldn't be without mine

Stick with it SFSR they are worth it

left hand pipe removed today, this little lot fell out:

yes thats part of the ring

a quick look up the barrel revealed one badly marked piston and a big gap where the top ring should have been. apologies for the quality of the next pic, i was lying on my shed floor using my phone to take the pictures:


so that's a bit of a minor set back. once there's a bit more space in the workshop I'll drop the motor out and strip it down and get it sorted.
I suppose it's more of a project now so when i have something else to report i'll start a new thread in there.

one final thing though, I've never seen this done before:

lot of effort there to save a few grams

I had a 400S3 triple many years ago, it was very reliable until setting off for work one morning it sort of fired for half a second and then just stopped.When I stripped it down it had bent a conrod............

Bad luck At least after you've rebuilt the motor you'll know it's right.

I would respectfully suggest that whoever drilled your footrest hanger 7u<k3d it good and proper

I'm sure someone will have a pair, although they can be hard to get hold of.

I might have a set in the garage if you want to replace them

yes please.

Me again,
just had a look at the spare ones I have, one side has been repaired, so it's not perfect.

Keep your eye on ebay etc, you'll find better ones there.

fair enough, thanks for looking.

Hi TOP TIP just looking at the chain i take it someone had a death wish using a link in a bike like this, always use linkless chains, at least this link was on correctly cheers wayne

I always used to avoid split links but have used them last few times and not had any problems

I don't see them being any more dangerous than a badly fitted rivet link - if you buy a bike with an endless chain you don't how it was fitted
