Wondering what your thoughts on this top end kit from "Japan"?

My experience with that ebay supplier is that they sell good products at excellent prices. Not everyone agrees, but Iknow of several people who have drag raced with those pistons and run them up to 9000 revs. They are not intended for that application but they are way better than some would have you believe.

I'd have no hesitation in recommending them for any street bike.

I've bought some stuff for my GT550 from that seller and have been pleased with what I got.

Can't speak to those specific pistons.

I have heard good and bad regarding their pistons. I bought fork tubes, and they are fine so far. At that price, I might have to consider them.....

If you stroke it more than twice; you're playing with it.

Too many bikes, too much time, ENOUGH SPACE, FINALLY! Never enough money.........

I have bought many things from them, never any problems. I have been running their pistons in a Kawasaki H1, no drag racing but lots of trips up the tach to hear that great sound.

I have just had a set of the 05 oversize. No running time yet but did find when gapping the rings one set were fine a little over bottom tolerance so fine with no adjustment, but the second set were almost at the top end of the gap tolerance out of the box.

Little disappointed with that, and not sure if rings are available separately or Suzuki rings are compatible.

The issues have been quality control for one. Once you have a lot of time and money invested in your project, do you want to risk it?

I have a new set of his GT550 Pistons 1.0 mm, GT750s 1.0mm piston and T350 Carb kit. There were issues with all the above that disturbed me, others seam to be OK with and maybe the issues are minor... I was able to find NOS and went that route.
