I also wouldn't waste my money for a "Limited edition kit" the "regular" one looks pretty good for the price.....
in the not-so-distant past, there were some problems that only afflicted the powerking 'standard' kits (and i am in no way suggesting zoom had any of them. just a fact about powerking):
CABLES:
throttle and clutch cables too short. meaning, the length of the cable from the ferrule (metal end of cable housing) to end of either cable wasnt long enough. another trip to the bike shop to buy a brake cable to replace the clutch cable, and as far as the throttle cable....forget it.
TANK MOUNTING STUDS:
those also, were shorter. made it really tough to get a nut on. had to do alot of bending of brackets to work.
WARPED SPROCKETS:
imagine holding a frisbee in your hands. now, twist each hand just a little in the opposite direction from one another. yeah. that caused all kinds of people nightmares, because the chain would bind and tighten up on one side, and fall off completely on the other.
a remedy, was to file or grind down much of the teeth to take some of the width off.
now, those problems seem to have been remedied a couple months ago, but they never happened with the Limited kits.
Limited have chromed dished sprockets, chromed idler pulley brackets, and in-line fuel filters. standards do not.
in addition, the Limited kits have longer cables, so if you want to install apehangers they should work.
DAX has excellent motorkits for around the same price. there arent any surprises with him. A-1 product/service.
you're looking to go inexpensive, yeah?
