so i was looking thru e-bay and notice a 720 kit which didn't mean much until i looked a little more, and noticed every thing wrapped in j@e wrapping which is the piston place that a certain builder went to work for (samcoe) so there is a new cheaper kit, some of you should research it and then call the ninja[img]i/expressions/face-icon-small-smile.gif[/img]

Its the stock JE 105 piston and sleve with gasket.

That's right! JE offers 105 piston AND 105 sleeve for stock cylinder, so AL bore would be thicker without 105 sleeve. Starting bid at $350 and $175 to install. Not a bad option with steel sleeve and standard quality JE piston for a wide range of uses. Another Excellent alternative. Good find SandMan.

AZ, lolol. Stacking them deep and selling them cheap. I wonder if he consulted NUT yet. Nut paid $2K+, and hypes for free around the clock. Hee Hee.

 

so what do you think jacket is this a good kit? or just another choice?

 

Thats not entirely true Yjacket. I paid $1699 and I pay to be able to hype!,lol[img]i/expressions/face-icon-small-wink.gif[/img] And I would do it all the same all over again because it's worth it[img]i/expressions/face-icon-small-happy.gif[/img]...........

 

don't forget the headwork that will need to be done to match the cylinder to the head, the entire perimeter of the head
will need to be opened up 2.5mm with a gentle taper to push the fuel/air mixture towards the plugs more efficiently.

 

Are you talking about the Pami custom fit pistons? Or breaking the flat edge. I haven't seen the slope yet, but no one had discussed it yet commercially or otherwise until you. That would be an optimal flow method, and I may not have noticed until assembly if then.


Thanks!

 

Would you be able to put that head back on the stock bore and still have enough surface area for head gasket seal?

PCP OFF ROAD Is definetly a good shop they have not gained notariety in the ds market but i know of several ds's they have built and they do good work they built Squatchers new bike build and he seemed very happy last time we spoke. they did him a HPR 730

 

Sandman,

Yes, JE is a high quality product. I'm not going to investigate this option; but for a single type configured piston, at least its a wide range use and not confined to a specific type racing. So it should be robust for a wide range of users, but there are many details to consider. Write the expert on ebay, and tell us what he has to say if you are interested. AZSAND's approval speaks volumes to me, since he is very knowledgable and an honest contributor.

 

I did find out the only reason JE has 105mm Bombardier sleeves, is its the same sleeve as Yamaha Raptor (with an R(aptor) at end of PN instead of a B(ombardier)).

Too bad more parts aren't in common.
