Here comes Jonny!

Watch the corners on the left side of that exhaust port. I would try to get them a little more rounded

I didn't actually cut in there yet. I wanted to see where it's at before I widen or raise... Just biggering the outside for now.

 

[RIDE-RED 350r]

Roger that, carry on my good man.

 

[Wagnerwerks]

I'm looking for a usable 51.4mm 372xpw or 375k cylinder. Or.... I have a piston for someone at $84 shipped.

Not for this saw....

 

[RIDE-RED 350r]

I hope you find a "W" cylinder.. I love mine!

 

[Wagnerwerks]

Ok... So I'm back..

Here's the hlsupply haul. I got a 268 piston on and checked squish the cheating way with just one long piece of solder through the plug hole. It hits with one base gasket, but with 2 it's fine. Squish with 2 is a nice .019". Each gasket measures .016 so that was simple.

 

[Wagnerwerks]

So here's a stock piston...

And here's a 268 slug. Do I need to source a different bearing? Anyone have a 268-272 bearing they can measure?

 

[Wagnerwerks]

Okay so I actually have a bearing that takes up the slack in the piston pin. I did come up with one Oddity. One of the two Pistons that I got for my Black Friday deal has the pin drilled crooked. I thought it was just my eyes or maybe an odd casting but after measuring it's about 1.5mm off. Think it will be ok?

 

[RIDE-RED 350r]

I would not use it myself. May be nothing to worry about but I wouldn't chance it

 

[Wagnerwerks]

Stock bearing...


Bearing I found in my box... I wish I knew what it was from....

 

[Duane(Pa)]

Not worth the risk in my book...

 

[RIDE-RED 350r]

Clutch bearing perhaps??

 

[Dub11]

Since its drilled off center won't it try to rock the piston?

 

[Wagnerwerks]

Kinda what I was thinking. I hate to complain about it but I may have to give them a call. Hls is truly one of the best businesses I've ever had to call up though so I'm sure it will be fine.

 

[Wagnerwerks]

Since its drilled off center won't it try to rock the piston?

I think it might but it's actually like the skirt will be turned a bit. Not a big deal till I put a new piston in it someday and the ports are off. Lol.

 

[RIDE-RED 350r]

I'm sure they will take care of you and I think you would be wise to not run it. I can't imagine anything good happening with that wristpin offset like that

 

[RIDE-RED 350r]

Wait a sec, both sides are not offset? Can the pin even be installed?? I'm thinking not if the other side is centered

 

[Wagnerwerks]

Clutch bearing perhaps??

Maybe... Not sure. It is in very good shape for that as it is used. It's a rediculously small amount too wide. I'm thinking a single stroke of a file on each side of the inside of the piston and it's perfect.

 

[Wagnerwerks]

Wait a sec, both sides are not offset? Can the pin even be installed?? I'm thinking not

Pin fits right in. It's like it was rotated a tiny bit too far when drilled and the piston skirt sits to one side of the port a little over 1mm more than the other side.

I got two. One for me and one for my buddy. The other is spot on and if I didn't have it, I'd have thought this one was normal.

 

[RIDE-RED 350r]

Gotcha...still a no-go in my book

 

[Wolverine]

Damm china bs. Ain't worth it.
