Well after some slacking off I finally got the go kart to the point where I could drive it still have some bugs to figure out, like a throttle cable and other small things but man this thing flys. If any of you guys dont know my build it's a rotax 399cc 2 stroke 2 cylinder snowmobile engine i custom fitted to a manco year go kart been building this thing for a while.

Daaang, that thing is 90% engine, 7% human, and 3% kart!!
Frankly sounds wicked dangerous, but that's why we do things like that and love it!

Yes man I never thought this thing would turn out how it did at all didn't expect it to look so good or for it to sound so crazy the exhaust I have on it rn was just temporary something I put together in a few minutes just to ride but it turned out so well. Will put mufflers on it though I have one rlv muffler for it and I need to get another for the second pipe

That thing is rad. And I like the exhaust. So, will she light the tires?

It probably would but theres only like 3 psi in the tires because it's been sitting lol so it has a lot of traction I should get more speed too once I air them up , since they wont be completely flat anymore

I have to watch the air pressure on my minibike. Sometimes it'll hold air for a month and other times it doesn't make it a day. But when the rear tire goes flat, it concaves, and has the tiniest contact patch. I've laid the bike down 3 times because of that.

But I do have a manco that looses 10 psi in 5 hours.

Yeah its just been sitting for a while that's why just needa some air and it will hold

Picture of how the exhaust with the rlv muffler will look just have to get 9ne more for the other pipe

Is that water on the floor or do you have the world's biggest carburetor leak????
How's it handle with that big ol' engine back there? It looks like it would understeer, but then again, 2 strokes are lighter. How much does the engine weigh?

No that was water had to clean the dust in the garage and wash the floor . Also it does understeer mostly with me on it and as I remember the engine only weights 65 to 70 pounds

No wheelies yet maybe soon kinda feels like it does want to pick the wheels up at times madmybe if it hit wot from a stand still but probably wont go that high to hit the cvt driven lol ,I guess me putting the motor so far in worked didn't want it hanging off the rear because I wanted it to be stable

 

[rushking19]

Just got my new ignition coil in the mail today and also decided I needed new plug wires was bout to order some,but then I had a bright I idea to make my own. So I used some wire from my old nology plug wires that was on my car and cut it apart and use the wire and the connectors and it worked perfectly even used the end of the end if the spark plug wire for the end of this spark plug wire
