600cc engine on racing kart frame

[KlaudioP]

Could anyone help me identify a go kart chassis because it has a double bars on both sides at the back and I have looked around and I found its code and it is LRGC2428 (what is its value etc) and I have decided to put the car engine in a kart for later on because my school decided to back out of that one in favour of asking me to consider a side mounted 600cc motorbike and I said yes. They are yet to give me the money to buy the motorbike but they said it is coming soon. I was wondering if side mounting it is the best option and I have done my research and I am getting someone from STEM to help out with the welding and I am going with the usual setup with 5 point harness, front and rear brakes and I was wondering if I have a too high a gear ratio of 35 tooth on the axle and 17 tooth on the engine for a kawasaki zx6r (the motorbike in question) I will start posting pictures, if all goes to plan I should start posting pictures in a few weeks time.

No freakin way we are going through another 7 pages of that. Wow. I might have to subscribe to this

Sounds like everyone likes to feed this guy!

Alright can anyone help me identify the go kart chassis I have which has bars on both sides at the back of the go kart.

give us some pics and then maybe we can help you.

This is the go kart and what I had in mind on sketchup. The lines indicate the engine mounts the engine will have. Hope this helps.

What's the motor again......????


And why do you want to wreck a perfectly fine gokart????

I would think that, after your previous attempt, there will be very few who will want to help you; hopefully, you left your attitude at the door this time...

If I see any sign of animosity from you, YOU WILL BE BANNED!

Oh & BTW, since this subject has nothing to do with the previous subject, I have split the threads...

This has been done a few times. Look on YouTube. People have put 1000cc engines on the back of karts before. If you are serious you need to get the engine with the transmission exhaust and the carbs. If there are any wishbone mounts or removable mounts get those also. You are talking about a good 100+ man hours if you want anything safe or reliable.There would be tons of design and fab just to mount the engine. If you want it to handle at all you should stretch the frame. And you are talking about someone else doing the welding? Thats hours more of consulting back and forth about fitment and materials. You also mention gear ratio? How many teeth are on the bike sproket? What is the difference in size of the rear tire diameter? If you match the final drive ratio of the bike you could expect a top speed around 150 MPH. You should look into something more like what is in the pics below. Also if you look at the bottom pic on the right you can see the custom billet aluminum mounts and the torque struts that went into mounting this 600.

That is the funniest thing I have seen this month. I luv it.

I'm with denny, I don't need a vacation, and I can see one coming if I try to help this guy again...

See this is why we need the poboy here! Lol

When you have the bike, and you actually show that you're serious I may help.

Either way you won't break any land speed records still.

I wont believe any pics or posts unless i see pics with a DIY sign and something like a ketchup bottle.
For proof purposes, until then pfffft !

I completely understand and I am going to get an answer from my school. Thanks anyway for getting me the specs. We are being given welder from STEM and hopefully a motorbike engineer. Anyway we talked to the welder and we think that we should put the engine next to the driver with the driver's seat slanted and there will be some kind of firewall protection between the engine and driver. We are going to match the frame's tubing when it comes to the extra framework and engine mounts. We are going to beef up the go kart chassis by putting x bars in the rear and middle of the chassis and we will put a rectangle behind the engine and driver and then have a bar coming from that the rectangle on each side right behind the stubs axles. Also putting the engine next to the driver/ slightly behind the driver would make it easier to implement the shifter because it comes out from the left side of the engine, on the same side as the chain and then I want to put the clutch pedal of the shifter stick and only have a 2 pedals, front brake on the left and throttle on the right and then have a handbrake style rod that is hand operated for the rear brake. Also I think if it was longer, there is a higher chance that the middle of the kart will flex and scrape the ground. The go kart that was posted by x5050160 is mad but we want to keep as simple as possible and this is for an engineering competition so we won't competitively race it, maybe go to santa pod with it also our welder guy won't have enough time to fab the whole chassis like that, he is going to do the strengthening and engine mouts and that's it and I haven't heard anyone get hurt in the simple gixxer karts. It is actually a side project where it will be used demonstrate the main part of the project. We've already finished the other part of the project so we have 5 months to make this go kart with around 800 pounds because we are getting the welder to do everything for free I bought the chassis from a guy who wanted it gone for 30 pounds so I got an absolute bargain with the go kart chassis. We will be using 11 inch rear tires and I think if I used the same ratio as on the bike, I would get a lower top speed because it has a bigger tire size so I thinking in the region of 30-40 on the axle and 15 on the engine. Eg 35 on the axle and 15 on the engine with a red line of 12000 gives me theoretical top speed of 168 mph which may rise or fall depending on the finish aerodynamics of the go kart. We will be using all the aero we can get with the pods and stuff and I think I will around a hundred bhp at the wheel. Any other suggestions within my budget.

[/COLOR]Forgot to say I will be using a 1997 ZX6R engine and I will be using the bike's front calipers 6 piston each for the front brakes on the go kart

My advice is: document every step of the build process with photos or video. You will need this for insurance purposes later.
