125-200cc Where to buy 144cc piston kit?

Is there enough material on the top of the piston to just lathe it flat? That would put the height the same as the husky?

Yes, it's enough, and i thought about it. BUT i was told that you can't hold piston in lathe, because it will probably broke.

It will not.

I machine custom pistons (lot's of them) all the time. Wrap them in a thin tape, like electrical tape to protect the finish, and you'll be fine. That's my plan if the oem piston becomes a problem.

Could likely stand the piston up on a vertical mill bed and hold it through the pin boss then use a fly cutter to take the top down too??

That would work too. That's how I cut the valve reliefs. Everything else I do on the lathe.

If a piston's going to break from clamping it in a 3 jaw chuck, I'm not sure I'd want that in my motor.

I thought about this last night and did a bit of research. Eric Gorr might have an option as well. He sells a number of 144 pistons, and apparently one of them has a lower compression height.

Another issue is - you want to hold piston in jaw chuck centered, but piston at his head and skirt has different diameters. So you won't be able to hold it evenly

It's not a problem with a small piston like that. I do larger ones as well, and indicate them with a dial indicator while chucking to make sure they're true.

The piston taper should be fairly minimal, plus there's the possibility of chucking it from the inside that might be an option - plus any marks left from the jaws wouldn't matter..

Was thinking, if anybody is having a hard time finding a piston and wants to send me one of the alternatives, I can do the fit-up and machining no charge. Just to verify that we have a legit option without having to mod the head.

Pistons are readily available.

It was a very low production bike. I'm now expecting to see them become unavailable.

The stock one is available, I checked and could get one from my supplier. I have had good life from OEM pistons as well so I didn't try looking for a different one.

As far as I know the other Canadian guy still doesn't have his. $200 in USD, converted to CDN, plus shipping and tax will be close to $350 for a piston. The last one I bought was less than $200 CDN including the top end gasket set.
Considering the extremely low production of this bike, I wouldn't be surprised to see the manufacturers stop making them. Just preparing for either eventuality. What happens if I need one mid-season? I can't wait 6 weeks, or even 2-3 weeks from the States at $350. It doesn't hurt to be prepared.

you could be right...but wossner makes a piston for all the 70s and up swedes still...

I can see why it might seem an odd thing for me to offer, but we've been going through this with the cars I've driven and raced for the last 20 years, and they were sold in pretty large quantity.
Maybe I jumped the gun, maybe not.

I'm still waiting for my wossner.......working with Rob Lang who is keeping me posted on status...got so impatient and concerned re parts availability of this bike...I bought a 2017 TX 300...problem solved....but still want the 144 as another "buddy" or spare bike.

Keep us posted. I won't need one for my bike for at least a year, but I'd like to at least know if they're available.
