Engine conversion
 

Hey...im new here but i have a single seater coolster... 150cc and im wondering if there is any manual bike or quad engine (250ninja or the like) that can fit with or without modification to the swing arm? Thanks... Conor

Here's one that BIG KID did:http://www.buggymasters.com/forum/showthread.php?t=1083

I take it reverse isn't a needed item with an engine mod?

Ahh nicee....any engines that fit nicely or do all need modification
and no reverse isnt needed

I've been using the Honda TRX200SX engine (with reverse!), they fit nicely. May not be as powerful as you're dreaming about but get's them around alot faster with more torque than the GY6. Whatever powerplant you decide on will require modification to the swingarm and will need brackets and mod's other places. Do you have tools & skills?
We can help as there are many wise and skilled members here. Good luck

Thats sounds awesome! i have welding skills and tools as doing a mechanics apprenticeship....is there a thread or pictures of your transplant or similar?

Here's a few:

This should give you some idea of what's involved.
