the is the frame after being cut to extend it about 15 inches in total this is a block i made on the lathe to extend the axle from 34 inches to 41 inches wide. i will also be making wheel spacers

Yes. The kart will weigh roughly 250lbs-350lbs and I want to have enough power to drift around corners etc. as i will mainly be using for off road. The last thing i want is to put all this work into something (not that i dont enjoy it) and be ultimately disappointed with the performance. Ill...

Its all theory of course. Only thing is when i was driving the bikes i took the engines out of, once in a while you would miss a gear accelerating and release the clutch in 3rd thinking you were in fourth and all that happened is there was a slight jump as the engine was brought back up to rpm...

thanks for the advice never thought of that and better to air on the side of caution. Actually regarding your earlier point about major damage being done if one engine upshifted while the other not shifting. Im not sure I understand why it will be so dramatic. Lets say im accelerating and am at...

I dont have them with me Ill take some more tomorrow and put them up. Im not exactly sure what you mean with 2 seperate clutches on the live axle. Are you talking about centrifugal clutches and if so how would they work attached to the live axle?

Ok thanks for the advice. I can see what your saying. I'll connect the two shifters with a solid bar running the with of buggy and weld brackets onto either end to attach to the splined shifter shafts at the engines side. This should be rigid enough to make sure one tranny shifts with the other...

Hi, Ive run into a problem with my engine setup. Ive two 125cc 4 stroke pit bike engines. Their off two chinese pit bikes me and my brother owned. There made by zongshen are produce about 8-9hp each and there 4 speed with manual clutches. There going to go on my mini buggy that I've just started...

ya thats the one....I'd say i'd get tired of a 5 hp engine fairly quickly and I kinda want something with a manual clutch and gearbox.....and about the Akermann geometry, I moved the pitman arm closer to the back of the kart so it is not on line with the spindles. when i turn left the tie rod...

Thanks for the quick replies. I'm wondering am i better off getting an 250cc 4 stroke dirtbike engine rather than an engine from a roadbike. I understand there are a lot of electronics involved in a roadbike (sensors, altenator, starter motor etc.), rather than a dirtbike engine which would be...

This is the most recent picture I have. I have the steering setup, rear swingarm, and front wheels attached since I took this pic.....

big difference between 125 2 stroke and 4 stroke.....

Hi i'm building my 1st kart/buggy. I need a few suggestions on what size engine will give me wheel spinning acceleration(on dirt) and about 50+mph top speed. I have a 125cc 4stroke pit bike engine that has 10hp and a 4 speed gearbox. The bikes top speed is around 55mph. I originally planned...

you could use the dirt devil plans. they are easy to follow and are fairly detailed. If you are going to use these i would advise that you add a few inches to the length of the frame to give yourself plenty of room. on the website there are a few pictures of people who built them but over sized...

ya i can see what your saying, it would reduce the lateral movement but still would it solve the problem?
