turbowrenchhead Posted August 14, 2012 Report Share Posted August 14, 2012 I'm getting close to having to decide what kind of pistons to run. Looking for ppl's input. I have my jugs ported to make at least 65 hp. I'm going to run a noss head with probably a 21cc dome for pump gas. Cast pistons don't expand as fast as forged so I'm leaning towards a cast piston.

bansheesandrider Posted August 14, 2012 Report Share Posted August 14, 2012 Definetly go with Wiseco Pro Lites. Yes they are a forged piston, but that is the type of piston used in EVERY true high performance motor from NHRA, NASCAR, and most other motorsports. Your qualified and expierenced machinist will bore your cylinders so that you have the proper piston clearance when the motor is at temperature. All you will need to worry about is breaking it in properly and letting it warm up correctly before every ride. Quote Link to comment Share on other sites More sharing options...
shanYE west Posted August 14, 2012 Report Share Posted August 14, 2012 WSM is my preference for forged. I'm going to try wossner next. I've used Pro-x cast pistons in my PTR national ported motor with 19cc domes for years with zero issue. Quote Link to comment Share on other sites More sharing options...
Coupelx Posted August 14, 2012 Report Share Posted August 14, 2012 WSM is my preference for forged. I'm going to try wossner next. I've used Pro-x cast pistons in my PTR national ported motor with 19cc domes for years with zero issue. Traditionally I've used wiseco for availability reasons but I've had my shit apart a couple times over the last 2 years and they are showing alot of wear. I'm not impressed. I am going to be trying wossner or wsm out next and for sure wossner in my 68x54 cheetah. If it was a lightly ported play bike I would run pro x pistons for sure. Why cast? Properly setup a cast will give a far superior service life, better resistance to scuffing and wear. Most OEMs use them for these reasons. Most people that say wiseco are just passing on information with no idea why. And for the person that will try to say 'well my wisecos work fine'. Indeed they do bit there are other options too. Edit: if you use a cast piston the clearances must be set to their specs. You hog that bitch out for a forged piston and then drop a cast in there it will fail in short order.

ATVridinMaNiAc Posted August 14, 2012 Report Share Posted August 14, 2012 I always thought JE made some good pistons but seems like they only make 4 poke pistons Quote Link to comment Share on other sites More sharing options...
dajogejr Posted August 15, 2012 Report Share Posted August 15, 2012 I liked the Vito's pistons I had in my cub. I know that's not the motor you're asking about...but they were thicker on the intake side than the Wiseco. See if they make one for your size motor.
