Grenade ?

If it snags a ring in that port do you really think its going to explode ?

Maybe the universe will implode Geoff.

ok so did this work out? I have an 84 that really needs a piston. and if a 86 piston will work I am on it!

One day, hopefully sooner than later, AdamN is going to ride that KDX with the funny 86 piston. I was beginning to think that he might do it while we are still able bodied but my hope is slowly fading.

Have you got a nikasil cylinder or sleeved? I got my sleeved cylinder out today and have to take a look at the nikasil one I have to take off a spare motor before I see which way I will be going with my next one.

If you're trying to keep an old bike running for occasional use, there's always the option of a thou or two coating on your old piston skirts to take up some clearance.

If you've got a sleeved barrel a light hone to square things up a bit (but not too far as to impact ring end gap) with a coated piston to get your clearance right and away you go

This one is for an '87. Easy enough to get a piston for but l dont mind trying out new things for future reference. Its a rough one but coated and cylinder honed to suit it feels ok. I'll see how it sounds when l get it running. $33 Australian plus local postage is all it cost.



This is the bike running with the piston on the left before l pulled it down.

I would be concerned about metal fatigue on that.

Ah now that would be a good alternative for Mrs KDXs bike there Geoff, where, who and what is that coating?? tell me more.

It doesn’t get ridden very hard at all and would do nicely to keep it healthy without using the big dollar parts up.

Easy to deal with too Brian

I ran a hone through the barrel and then got the piston coated to suit. I think l ended up with about 5 thou clearance after the piston was coated without an excessive ring end gap.

I've bought complete running bikes for this sort of money !

Well, there's a pic of the piston ring pin locations.
