Ok, but not sure if you can buy the set. It is hard to find some reliable info, so just for curiosity, question 12 http://www.wiseco.com/FAQs.aspx Good info there, looks like the same rings for a cast bore are also used with nikasil from what they said. There are companies that make custom cast iro...

Got the PM, need a minimum number of posts to respond.
Sounds good to me though. pm me a way to contact you, Ill let you know details.

In case of chrome cylinders, will you have suitable rings too? Before you mentioned sp rings designed for nikasil, i believe these can be used in cast iron sleeves. Another point is for different pin diameter on other pistons. If diameter is smaller than on vtr rods, you can make new bushings. Pric...

I did contact 2 companies about nikasil after the machine shop incident. Both said it doesnt adhere to cast iron liners. Haven't looked into it much since.. Not saying it cant be done, but I couldnt find anyone who does it on iron here in Canada. In the US and Canada Millennium Technologies LLC Mil...

Im fairly sure they will have ring options available for any size piston. They could cut the ring lands to fit which ever ring set is suitable. I could also go up to 100mm, and use sp rings. but as it was mentioned, they are likely designed for a nikasil bore JE will contact me tomorrow..Ill let you...

I am still waiting to hear back from JE, but im assuming that they will provide the proper rings, if not I think that 98.5mm rings would likley be sufficient?? Or would tge end gaps be too large? I talked to them on the phone last week, they did mention that those rings may not be available in that ...

Well I recived my pistons from being coated. The crown coating was chiped around the edges out of the box, piston skirts had pitted spots from bubbles, and sagging in the coating. He was supposed to add .004 .. but there was an extra 0.007 When I called back to see wtf happened, he informed me that ...

I looked through alot of catalogs... the closest pistons I found were an xr600 big bore kit, xl600 & xr650L. They all have a 24mm wrist pin, you can get a 100mm bore, compression height is 1.15" (I measured the stock storm at 1.19") So the stock 650 piston would work.. but would be aro...

Thanks Stephan, So far ive tried wiesco, and je. Havent heard of woesner though, ill give that a try.

You mentioned possobility of big bore in future, now it is coming serious. Especially if second bore will be for free. I would sell the pistons and found new oem (maybe worn) ones from other bikes. Just check piston to valve gap or before final assembly. What about 100mm from vtr sp? Or other bikes...

I just picked up my block from the machine shop, they made an error when measuring piston to bore clearence... He thought that clearence should be measured with .003 on each side of the piston. Its now .006 instead of .003.. :wtf: completely f'd up the build. $750 later and I'm back where I started....

Yeah, I did consider doing that.. It does seem like a good option. Would be good for heat transfer, its claimed to last longer(but that's not always true) , could be used with a tighter clearence with a aluminum piston. I personally would worry too much about the structural integrity of an aluminum ...

Yes its made of ductile iron, I heard because iron doesnt conduct heat as well as aluminum..it will run hotter. it's much thicker than the oem sleeve.
I cant see it being a issue at all though.

Now if i ever rebuild again, I can fit some big bore pistons
