Best Speed Kit for Magnum MKII

Alright, I got a puch techno boss exhaust pipe, a bing 15mm carb, and a high flow performance air box all on a 1981 puch magnum mkII. I am still working on it right now, it doesn't wanna change gears on me but I think thats the tranny and should be an easy fix. Once I get it running up to par I wanna toss a speed kit on it. Any suggestions on which one and anything else I need?

ZA50 Tranny is NOT a easy fix, but it sounds like you dont have much torqe with that pipe, look for a new old stock 14mm intake manifold, my 79 MKII had a 12, i dunno about yours.

plausibe it doesent have enough ummmphh to get into 2nd gear.

Dan's right.

The Polini is simply the best smaller bore (under 80cc) speed kit made for the Puch engines.

A nice 19mm carb on there with a quad reed block and you got yourself a 50mph+ ped.

Um.....get that tranny working PERFECTLY before you kit that bitch or you will be buying a new engine!

Re: Best Speed Kit for Magnum MKII

Don't worry about the tranny, i have tango'd with one before in a similar fashion. I am just looking to the future, I am not gonna buy this kit for a while, not until I am sure everything on my bike is perfect and fantastic.
