Hey Brad, how does the RG piston and sleeve stack up against the stock sleeve? Any real performance difference positive or negative?

I will take the first engine if I can shoot you payment over Sunday!
 
Hi Brandon,
Never did much testing with a standard p/l. Wouldnt expect any performance gains, liked being able to flow the RG sleeves, and found they ran strong for much longer.

No rush on payment.

Hi, the case on these engines have been bored out so the the RG sleeves fit without needing to modify or reduce the thickness of the RG sleeve.
The stock sleeves wont fit these engines.
I will be listing my entire OS inventory including NIP pistons/sleeves.
I also have new RZ piston liners which will fit these engines, they gave pipe timed exhaust port which will work great with a tune pipe.

Brad I didn't.realize the case had been bored I'm going to pass on the engine.

No problem, I actually forgot i set these engines up this way. Will update the first post.
Best way to go if you intend on running the ABC RG sleeves, If you intend to run the standard ABN sleeves a standatd case would be needed.
 
Brad if engine 2 still available I'll take it. Do you have an extra air cooled head you want to part with?
