rd shifter kart idea

Its gotta start with the the kick starter so its gonna have to stay there but im gonna have to come up with more room somehow
 
You could make an aluminum shield from down at the seat and over the cylinders. It will shield you form the heat and give you an arm rest. Plus direct the air over the engine nicely. Get rid of that steering mount and use a single tube mount. You'll have more leg room. You might have to get creative with the pipes or run them forward and exit by the front wheel ala GP sidecars.
 
I have an 05 GSX-R600 engine if somebody wants her to make a cart with. It has about 3,500 miles on it. Has harness, ECU, injectors, radiator/fan, and the right side controls. I'd let her go pretty cheap, it's just sitting in my garage, taking up space.

Brother I love karts so I do not know how I missed this thread! Our family has a long kart racing history, I used to run speedways and still have a couple of our karts here at the shop!

Your kart looks like an older road course kart which has the seat and steering in the middle of the kart to help keep the left to right weight ratios close, oval speedway karts are offset to the left side for more left side weight however it is very easy to convert a road coarse style kart to a speedway design as all you really have to do is cut the steering shafts supports from the frame as well as the seat mounts, move them over to the left side of the frame, and weld them back on.

Running a motorcycle engine on a kart can be difficult to gear due to the small size of the tires so you will most likely need to run a very small gear on the axle, most of the older karts have a one inch axle however if you convert it to a modern one and a quarter inch axle a small block chevy crankshaft timing chain gear will fit right on the axle and is a 35 chain! The modern axles also have a keyway the length of the axle so you can simply slide the gear from left to right to align the gear with the engines drive gear.

The last motorcycle engine we ran on a kart was a RM125, for the shifter we just turned the foot shifter straight up and welded a bar to it so it is right next to you when you sit in the seat and we mounted the stock motorcycle clutch lever to the handlebars! You are going to need to run a fuel pump however that is easy as well, get a vacuum operated pump from a riding lawn mower as it just has one vacuum fitting that you can connect to your intake on the engine and then it has regular in and out fittings for the fuel line. If you get a racing kart fuel tank for a limited modified or two stroke racing kart they bolt right to the floor pan of the kart below the steering.

This is one of the karts that we used to race and I am currently restoring it now, it was originally a road course style kart that we modified for speedway racing. I just mounted this newer style speedway body on the chassis and I am getting ready to paint it now however you can see how it is offset as well. Brother if you build your kart speedway style you will have a lot of room for the engine and to have the shifter next to you!

Gone but not forgotten - a set ot RD/TD/TZ kart pipes for inspiration

Or a very beastly peak. OK for a 250 motor. Where they join the barrels is really restrictive though as they change direction too abruptly. Kart motors use a different approach to powerband though.
 
I swear I remember seeing a factory Yamaha 250 kart back in the '70s. Yellow with the black and white checkerboard stripe motorcycle fuel tank between you legs. Searched on Google with not much success, found RC100S but not what I was looking for. Thought it was in a Hot Rod magazine (yes, Hot Rod used to do karts, and boats)
