What piston?
-
@Calum In fairness I've probably been too harsh. I've no experience of them in a 2 stroke, but I wouldn't use a forged piston as I said - the principle benefits of a forged piston are irrelevant in a 2T, and there are some downsides too, involving the metallurgy of the alloy amongst other things.
I've used Wossner car pistons many times at a former employer, (and bike 4T pistons once) and never been impressed with either consistency of size or finish, and quality of material. So I assume there is rollover in the way they produce bike & car product, making me sceptical. I ought to point out that I have been in motor race engineering for 35+ years and our standards are relatively high - maybe the Wossner product is fine, but when there's a better alternative...I take it.
As for their rods - there is a very good possibility they are much more than adequate, probably even great. I don't know, but these days you've got to be using some hick chinese producer to get a bad bike rod...and Wossner have a reputation so I'd bet they are ok for the forces generated by a DT. -
@SpookDog Taiwanese manufacturing often as good as found in Japan - in my experience. There is little evidence to support hard anodising of piston crowns when the piston is manufactured well in the 1st place. PVD coatings can be great, but unless designed in, and included in your bore finish & clearance allowances, a waste of time/money. It's very, very often just a sales gimmick as properly useful PVD coating is not cheap...

Wow! Hold yo horses! I’m only going on what I’ve heard. Like I said, I’m in the dark here. I know nothing about Taiwanese manufacturing. I only know Japanese and German are usually best...
Hence, I’m very interested in all opinions...
Please keep them coming. I need other people’s opinions to help me through this mine field... -

So Vertex or Mitaka seem the pistons of choice? (it was the PJME website that I saw the ‘cheaper made’ Taiwan Mitaka piston comment, by the by) I’m guessing I’m gonna go for the Vertex, if I can get it at the right price. Just for the guaranteed quality of nothing else.
I don’t see any point in a forged piston if I don’t have any other tuning, or the knowledge to make use of its potential. It’d just be ‘lipstick on a pig’
Cheers for yous opinions buds!... -
