well here's my problem, redid all of my 50 frame, suspension etc, and put it all back together but the stock motor that came with the bike has a couple issues, which would probably require a fair amount of motor work, resulting in the upgrade to an 88 kit while I'm at it..... now here's my question, since its been strictly a mod bike, should I spend all that money on the existing old motor, or just buy a complete chinese 88 motor??

also I just want a bolt in that doesn't require any modding, is this possible? and what size of motor? brand? would anyone reccomend? price estimates are welcome too....
Thanks...more power is a plus too though....

Most bang for the buck. I found the Lifan semi-auto to be very reliable. Have the 70cc & 90cc to be excellent.

If you what to kick it in the ass, go with 90cc. Put in a set of BBR clutch springs in the lifan clutch. That all you need there.

Pick up a lightened flywheel from T-Bolt.

Use the carb that comes with it or better yet get a TBparts 20mm. Put in a 92 main jet.

Have done this in quite a few Z's will great results. Run a 16t frt./ 34t rear sprocket.

With a 225lb rider - Radar proven - 45 mph top end. And still a good set for dirt too! You can just keep rollin on in 2 & 3rd gears.

Hope this helps. Just my opinion, others may disagree.
