Everyone that knows about weight to power ratios knows that the lighter the frame you have, and the bigger the engine, the faster, and more responsive the quad. Well up here we've come up with a seemingly good Idea, stuff a 400cc single cylinder, into a 350 frame. But here's the problem, the frame is yamaha, the engine is suzuki. Does anyone see a problem here?

Oh well, we'll figure it out.

 

why not a 4cyclinder road bike engine like a gsx-r or a kawasaki kx500 dirt bike engine. Much faster and cooler. If you plan to do this you will have a bit of custom parts to make.

 

As long as you have a welder, some fabrication skills and some patience I think it is possible.

 

I've done this type of thing before, but I never had mixed brands before, so I think I'll be ok. The other engines would DEFINITLY be an improvement, but due to lack of funds, I can't quite get my hands on them, So I suppose this will have to do. Mabey some day later on.

 

put the motor in a 230 quadsport frame

 

I want to do someit like that as well but there is 2 things stopping me I don't have welder or money!!

 

The money can be a problem, thats why I usually pick up broken stuff, and combine working parts to make something that runs. The welders are different, I usually use my schools. Kinda handy being in highschool metal shop.

 

Is the 350 frame any lighter than the 400? If not you really ain't gonna see that much difference. Just my .02

 

i bet the 350 frame weighs more

 

That's kinda what I was thinking. If it's a warrior frame those things weigh a ton. Might be just slowing the motor down.
