A 66cc kit would be like a 46mm piston correct? Or are the 70cc kits actually just 66? Also where would on get such an exhaust? I'm not sure where my scoot is geared, it is a zx50 from kymco has 12 inch wheels and so I'm not sure how that plays into where they out the final gearing at...like if it is adjust for the wheel size or not.

44mm or 45mm kit

I don't know what gears are available for a zx50

Hmm...yeah, I suppose that I am not to worried about gearing, I live in Baltimore, so there is a fair amount of stop and go, I have a moped that does about mid 40's and that is a 1 speed, so I imagine on this dual variated setup I'll be fine.

Here ya go The complete package.

Saw that jingway jawn but I am pretty unimpressed with that exhaust, I think that doing something with a 28mm header woulde be better, that 26mm seem like it is more a stock replacement type of deal.

Greetings:

I haven't used that specific pipe, but it looks a lot like my Hot Surfaces exhaust from Tazland. If it works anything like mine, it's a lot better flowing than stock, although a bit louder too. It supports excellent torque down low and keeps breathing all the way through 8500-9000 RPM - that's with 86ccs' displacement and a ministroker.

If you find the exhaust wanting, you can sell it and use the proceeds for a PG Long or some Asian exotica - still keeping within your $400 budget.

An encouaging reply, you have any idea what that hot surface pipe has for a header diameter? The smaller 26 would point towards a lower end pipe. I could always wrap it and move the power band up a bit if necessary.

Can anyone speak to the parts that jingway is selling? Like the variator and all?

Greetings:

Next time I pop the Hot Surfaces pipe off I'll measure and post.

My first Flash 4.0 was one of JiangWayne's 51mm Bores. It did not end well, partly User Error to be sure. However the quality and precision of all the Taiwanese bores I've seen (3 to date... ) doesn't come close to that of the Italian Jobs and not even as good as the Nikasil 49 - also made in Taiwan.

Perhaps the cylinders aren't matched well to the pistons dimensionally. Maybe the casting and machining lacks precision - out of round or just too much part-to-part variation. Then again, possibly the quality of the metal used isn't up to snuff for the intended purpose.

Whatever the reason, the Taiwan bores I've installed aren't nearly as forgiving as the higher-priced options, and need careful attention to the break-in process, lubrication and jetting. That said, opinions have been put forth from Hawai'i that numerous success stories have started with inexpensive Tai bores, some without a clue about jetting. Maybe it's just bad luck on my part getting a couple of "clunkers". For the record, my Char-Mo 50 from VT Cycles has so far survived my tuning "skills" without a scratch, as has my Nikasil.

Doesn't the zx50 use a larger wrist pin? I think you need primaries if you are going to change the gear ratio.

Everything seems to point me in the direction that it is a 12mm pin, but shoot, I don't know, I am fairly certain I have a 2002 model if that is any use to any of y'all.

I have dealt with similar type bores on my moped and imagine Ill be alright, I expect to have to clean it up a bit before running it.

Greetings:

As promised, these are the header flange dimensions of the exhausts.

PG Long = 28.6mm. That's the diameter of the hole in the flange/mounting plate. The pipe welded to it is a bit larger than the flange.

Hot Surfaces (from Taz) = 29.0mm Pipe seems to be flush with the mount flange.

I suspected that a 26 would seem to be limiting, I imagine for the 4 bills I can pretty well replicate most of the jingway pack with stuff from daywot or the like, and after the freebies from scooter assassins.

So I think big things would be bore, pipe , and variator.
