Wiseco pistons for racing?
I had intended using Wiseco's in the TR500 replica I'm building up, but have got a couple of opinions that they are not great pistons these days. Anyone got experience with them in a race motor?

Re: Wiseco pistons for racing?
They are still better than oem pistons.
A lot of racers are now using these.

Re: Wiseco pistons for racing?
it rather depends on how hard your going to go with the engine, I use mitaka pistons for any development and these days use wossner pistons as they are better than wiseco these days, had a few problems with ring pins retracting on wiseco and rings popping into ports as a result, quite messy.

Mmm, that sounds a bit worrying! Wiseco have actually now come on board as a part sponsor of the team and are making up a special batch of different design pistons for us so hopefully they will be OK

It's USA, where our design engineer is based. Pistons have different ring configuration, skirt height and boost port.Pete O'Dell wrote:whats the difference out of interest chris, is this wiseco USA or Holland?

Hi Chris
I have a T500 / TR replica which I run in the Spanish classic Championship,(5 race weekends per season plus training etc) I have run the same Wiseco prisons for 2 seasons without any problem.
I run ELF 909 oil premix only at 3% and have no issues, on the one faster track Catalunya (Barcelona) I run 4% as the straight is more than 1Km and there are a lot of 4th Gear corners. I have some race wins and other podiums. the engine rev`s to 9000rpm.
We will only strip the engine now as I am using a different bike for this season.
cheers
