Motorcycle engine or general purpose?

[ninjazoomer3]

Hi again, so for the go kart I'm building I'm having some trouble deciding what engine I should put on it. The 2 that I'm deciding on is a general purpose Chinese engine with 6.5hp. And a much faster new Chinese motorcycle engine. The 6.5hp engine will be about $200 with clutch and $270 with torque converter. The 250cc motorcycle engine will be about $450 with all components. I know that I will have a much higher top speed with motorcycle engine witch is why I might pay the extra buck. So I'm wondering what you guys would choose. Also I'm alittle confused about motorcycle engine, would you switch gears with a piece of metal connected to where the foot lever usually is? If I choose the general puprose engine is a torque converter worth the extra cash?

If you are getting the motor with TC, that is a good deal as the tc is worth about that new(Im assuming this is a new motor).
More importantly, what is this for?

The thing to remember here is the motorcycle engine will have more power than a Honda/clone, more than double (the 150cc are rated @13hp) so, not only will you have gears to get you moving & move faster, there's more power as well!

The downside is the bike engine is more involved & takes more work to set up but, once it's done, it should be a blast...

I have thought about this a lot myself. Besides gas and brakes, you gotta have a mechanism for clutch and shifter. 250CC is stupid powerful and fast for a motorcycle/dirt bike engine on a go kart. I wouldn't let a kid touch it with that engine on it.

A 6.5hp w/torque converter is a good balance of hill climbing power and gives a decent speed. All around less complicated to install and run.

For the motorcycle engine, like Fabroman says, you are going to have to be proficiant at fabrication

For my first build I think I try 6.5 HP engine with TC.

In new to this how do you do a quote?

 

[mckutzy]

There is a quote button right at the end of each dialog post box.

If that doesnt work, or dont want to quote but direct your comments to a specific person/people publicly, Just type there name(s) and your question..
