blowit Posted February 13, 2009 Report Posted February 13, 2009 We are doing a small study on pistons right now. Mostly because we are seeing several piston mfgs now and Wiseco is towards the top of the price war and not necessarily any better performance wise. We are comparing designs as well as metallurgical compositions, hardness, etc. Just curious what you guys have had good or bad luck with outside the normal Wiseco breed? Two stroke and four stroke pistons included. Quote
BSHEE400 Posted February 13, 2009 Report Posted February 13, 2009 i've had good luck with "wossner" pistons Quote

Two stroke and four stroke pistons included. I have always gone wiseco just because they are a big name... And trusted I am very interested to read your results and see what company is putting out comparable product... What are your findings thus far? Are you looking into the coated pistons at all? Namura is one company I'm curious about Quote
SAVAGE420 Posted February 13, 2009 Report Posted February 13, 2009 (edited) Well i ran the same OEM pistons on the stock bore from 01-07. Then just honed my jugs and popped in wiseco's just because from 07-now. .20 over here in a bit cause it's time for a first bore and on wiseco's again. :thumbsup: Edited February 13, 2009 by savage420 Quote
NYUK Posted February 13, 2009 Report Posted February 13, 2009 bad luck with pro x in semi high strung bike. terrible luck with l.a. sleeve pistons. shattered one at 111mph on a quarter mile run. i run wiseco only. Quote

And trusted I am very interested to read your results and see what company is putting out comparable product... What are your findings thus far? Are you looking into the coated pistons at all? Namura is one company I'm curious about We are more or less looking at the substrate, grain, weight, ring quality, structural design, etc. IMO, every piston in the market should have a coating so comparing coating and no coating is like comparing a model with undies on and a model without undies. One is good, but the other, just better :biggrin: Moly coatings are ok and more seen in production stuff. We have been coating engines with synthetic lubes and heat barrier coatings for years and they do even better. Brandon Quote

I'll be sure to steer clear Lucky you didnt get a chunk of rotating assembly in the leg at 111mph :ohmy: Quote
