[simon k]

with a shortage of asso piston's at AF due to the exchange rate, is there a suitable 72mm wiseco available?

Yes....i cant remember which one of the top of my head....but contact either David Blythe or FOXHAT on here and they'll tell you....they love all that stuff.

Also...Ben told me on Sat that the 72mm pistons are sitting in the factory waiting for delivery and they will ship as soon as the exchange rate hits €1.13 to the £. But if that doesnt happen in the next few weeks, then they may bite the bullit and ship anyway....but have to pass on the extra charge to the customer. They are resolving to do nothing for now, until a choice becomes clear.

I will say though......the new 72mm piston is unbelievable.....i've seen a couple, and they really are nice....VERY.

Cheers Shaun will follow those leads. i quite like the idea of carrying a spare in the toolbox when touring on this kit, so its nice to have some options. the 72mm asso is top notch you say? i look forward to seeing one in the flesh. if the customer does get lumped with it we are looking at the £130 mark!

Its Dan...not Sean....i'm the the good looking one.

Not sure of the benefit of carrying one in the tool box....if you get to the stage where you need to replace a piston....the scoot is better off in a van or on a trailer!

I was pleasantly surprised when i saw the piston....its as good as any Wiseco or MB piston that i've ever seen.

oops, sorry for the confusion
looking forward to going up to AF on saturday to pick mine up, albeit without said piston

Exhange rate is 1.14 and has been like this for a week

[drunkmunkey6969]

maybe he said 1.30????

Can't remember!

most early mx 250s have oversizes up to 72mm, but are single ring, although an it 250 piston is 2 rings, also most if not all are 18mm pin, dunno where the pegs would be on any given model but suffice to say that the single ringers have the peg centre of the piston directly opposite the exhaust port, you also gotta think of compression height, probably best waiting for the right piston

Wiseco 423M (from 71 to 73mm) - it has a 16mm pin, compr. high 32mm, 68mm long - you need a longer
conrod and have to check the inlet timing, the piston has no holes for reed-induction, pins are in the
middle of the boostport-side....cheers

thanks for the reply's. i was up at AF on saturday and lucky enough to bag the last asso
