[trx250rider]

i got some more pics of the cylinder and piston for you all to look at.

C-LEIGH....i took a pic of the front.i think your right and this is most likely the same cast as the powervalve,just not machined.i also took a pic of the piston for you.i wonder if you send it back later, would they machine the power valve in for you.

I think Neil probably wanted to see the intake side of the piston.

I don't know about E1, but the C7 might be the porting. Did you get TRX 7 porting or TRX9. If you got 9, then who knows.

trx 7

Well, not realy, what I was wanting the see was the machined area around the wrist pin hole & I can see its the same as the older pistons.
I can see enough of the intake side to see the cutaway on the skirt is like a late model CR pistons, squaire & not round.

I can see on the cylinder, the exhaust flange mount is thicker than the Pro-x & shaped different at the bottom. On the left outside, the ESR cylinder dont have the round bosses cast into the sides. On the Pro-x cylinders, thats the first things that are machined on the casting so it can be alined & mounted to the CNC machine for machining.


Called Monday to ESR, after all these years dealing with them, first time I talked direct to Eddie himself.
Hes interested in getting this new cylinder perfect as can be & willing to listen if any problems & to correct them. We talked for a good while, & in that time, I could see hes not going to kick the 250R to the side, maybe the 4 strokes but not the 2 strokes.
Willing as he is, we as 250R owners need to keep that in mind & lets not mess that up.
We dont need to throw LA Sleeve or CT Racing away either because they are still devoted to the old R as well.
Got to support who supports you, we all need to stick together.

In the same spirit, Arlan Lehman (founder of LRD) has branched out and created a new shop called LED Performance, and word has it that he's excited about rekindling his love for the 250r.

Have you talked to Arlan much Wilkins, has he changed up any from when he was on MacDizzy or still the same Arlan we all remember.
PM me a number where I can call him please.
