GSXR kart build help [Archive]

Working on designing a GSXR kart and honestly Im a bit stuck on the mounting of the engine to the kart frame. Im concerned with chain tension and how to solve the issue. Ive noticed some threads discussing rolling chain tensioners but the general opinion on that seems to be they dont last and rob power. I considered a mount where the engine tilts pulling the chain tight. However, not only does that leave room for the engine to move around, it seems like the wrong way to solve the issue. Also the motor is an 02 gsxr 600 and they seems somewhat popular with the fsae crew so I thought this would be the best place to come for help. Another issue is creating a sprocket that will work with the bikes 520 chain and mount up to the karts live axle. Any suggestions and/or tips would be great. Thanks

Thats actually where I got the idea from. However , not only is that an older engine with different mounts he didnt even seem to address chain tension and I cant tell what kind of sprocket that was used. Also Ill be going for a center mounted engine to balance out the kart better. Let me know if you have any other ideas.

i think your only option is to have the rear drive shaft move in a similar way to that used on FSAE cars, enabling you to tension the chain. i think shimming the axle bearings rearward is your only option, and the most sensible/safe. chain tensioners are dangerous in my opinion, not to mention noisy as all hell

And to think.... People call us crazy for putting 600cc sport bike engines in 400 lbd cars... Try a 250 lbd kart w/ no suspension.

I'd drive it.

On that note..
You could look into a square wheel bearing holder that rides in between two rails that would allow it to slide. You could tension the chain by sliding the entire axle/sprocket/brake (I hope you'll have some serious brakes) assy back using a pair of bolts w/ jam nuts.

You could also go for a swing type system in which one corner of the bearing is mounted, and the other mount can be pushed back to tension the chain, but with a system like this your ride height would be dependant on your chain length.

As for the sprocket, I'd go with a racing kart style quick change sprocket hub, and have the proper thickness AL cut. Durability may be a factor here, but I'd worry about actually putting enough power to the ground on kart tires to hurt the system (since we can barely do it on 20x6 Hoosiers)

:Edit:
Just watched the video. If you're gonna do this shit, wear a f'in neck brace, you know some safty equiptment. It will kill you, it wouldn't take much to flip one of those.

If Im understanding your method correctly wouldnt it be better to make just then engine tilt rather than the entire rear end?

Probably. Thats how it would be done on a "real" kart. Either method (of moving the axle) would affect your setup on a kart like that. Just be mindfull of your design there, because a cheeze design can really rear it's nasty head on a project like that.

Here's a couple of ideas:

1. You could mount the rear axle on some pillow blocks that have slotted bolt holes so you could slide the axle backward until the chain was properly tensioned, then tighten the bolts. You'd also have to slot the caliper mounting bracket so you could slide that back with the axle. Just make sure you have large enough bolts so you can clamp the pillow blocks down securely enough so the engine doesn't pull the axle forward under power.

2. You could slot the front engine mounts so the engine could rotate forward.

I'm not entirely convinced that rotating the engine will give you enough sprocket travel to tension the chain. The output sprocket looks to be 1/3-1/4 the distance from the rear mounts that the front ones are, giving you 1/3-1/4" of travel if the front mounts are pivoted 1". 1" is a lot to be rotating the front mounts for relatively little adjustment. I'd just make the axle movable.

With a center mounted engine your frame will have to be longer than normal.

So bolt the engine solidly to the rear of a standard frame, just behind the driver. Then make a separate sub-frame that carries the rear-axle and its bearings and drive sprocket, and the rear brake. Bolt this to the back of the main frame using spacers to adjust the chain tension (ie. have the mating surface vertical-transverse, and the bolts longitudinal).

The axle should probably have three bearings carrying it - two outer ones near the wheels, and a middle one as close as possible to the drive sprocket (to stop the chain tension bending the axle).

Oh, and it might be a good idea to mount a parachute somewhere... Make sure you get someone to video your first run, and put it in your will that they post that video here... http://fsae.com/groupee_common/emoticons/icon_biggrin.gif

To help keep the same basic dimensions as a regular 125cc shifter cart, one could use a V-twin engine instead of an inline 4-clyinder.

This would allow you to put the engine more forward toward the center of the kart, just to the side of the driver, since it is narrower then a regular inline 4-clinder.

I think thats a fairly good idea. I was going to cut and weld in another 12" or so pipe between to stretch the frame since it will need to be longer but if I can also solve the chain tension problem at the same time, even better. Do you think the center mounted engine is really the way to go btw? Ive seen several motorcycle powered karts and most have the motor mounted next to the driver, but then balance is a big issue correct?

Yes, I'd go for the center mounted engine. The extra wheelbase should make the kart more directionally stable - a bit like a dragster - which will make it easier to control. The more even lateral weight distribution will also help.

Your GSXR kart won't be any faster around corners than a normal kart, maybe worse braking performance because more weight, and acceleration off the line won't be much better because it will be traction limited. Your weight distribution will probably be around 50:50 F:R (like most FSAE cars). You will need more than 60% rear for really good acceleration off the line. But you will have much better acceleration out of medium and high speed corners, and much higher top speed, because of the extra power.

I guess the biggest advantage over a normal kart will be the fun factor - you should be able to smoke the rear tyres anywhere, anytime! http://fsae.com/groupee_common/emoticons/icon_smile.gif

just to add to the complexity, why not have 2 rear axles with 4 wheels, more grip for fast acceleration http://fsae.com/groupee_common/emoticons/icon_biggrin.gif

just watched the video, whats more disturbing:
- having the petrol tank snug against your crown jewels
- Having your elbow on the cylinder head
- or both of the above and deciding that a fire proof race suit is a waste of time!

Thats a crazy project!!! http://fsae.com/groupee_common/emoticons/icon_eek.gif
My best guess is that it will handle more like an AA fuel altered drag car than a go kart.
Just remember to put a good chain guard and two throttle return springs on.
Check out the 250 cc. superkarts sometime. They are very impressive.

I second what Bryan just said. Some type of failsafe design would be best. I coudnt imagine how scary it would be to have a stuck throttle on any vehicle let alone a kart with 1000cc engine.

Im starting to question really how important chain tension is. I mean if you have everything tight when you weld it how much will that big 520 chain really stretch? I like the shim idea and having it in two parts but thats a bit more complicated than I hoped for. Then again the projects middle name is "complicated"

Here's a picture of a pillow block bearing for the rear axle to use to move the axle and adjust chain tension.

The bearing is slotted, but I would slot the frame also. Chains do stretch, plus, many formula teams have learned the hard way about chain length. Chains are put together with and inside and outside link pair. So your chain will only fit together at even lengths...60, 62, 64, 66... There are things such as half links, but they do not make them for motorcycle chains such as a 520, 525, 530.

To answer help with a rear sprocket, http://www.sprocketspecialists.com will custom make any sprocket for you. You could even order a 2 piece sprocket so you don't have to remove the axle to change ratios.

Chains stretch a lot more than you would expect. We saw a half to 3/4 of a link...

They do make half links for the 520 chain. We get ours from hyper racing. I am not the drivetrain guy, but I am almost certain that we use a 520 chain.

seriously, shims!! those blocks will move no matter how tight you do the bolts. im sure they're fine for anything upto 125 but above that the torque will just rip them forwards in their mounts. that or the side closest to the drive sprocket will flex giving you a certain amount of rear wheel steer under hard acceleration. by all means use those bearings (if you have to), but mount them verticaly.

Okay guys I figured I would do an "update" as I got the tubing in today. Ive chosen to go with .095 1 1/8" chromoly tubing to extend my frame. Since Ive posted last Ive bought a 520 chain conversion and sprocket hub as well as the kart sprocket. Ive found a chain tensioner that is also used on similar type of racing karts. So it seems as though chain tension shouldnt be as big of an issue as I originally thought. I suppose what Im looking for is a rough idea as to where I should beef up the frame and how I should go about making it nearly 12" longer. Here is a picture of my current chassis.

You are very brave........

For your own safety (unless you are trying to help prove that whole darwin thing) at least put something in front of your feet. Even a hay bale or deflated tire would hurt real bad when you come into that curve a little too fast.

To be somewhat constructive, similar ideas of downshift actuating the clutch have been done with great success and simplicity. A really easy way would be fab up any sort of mechanism like you have pictured and hook up two shift cables from one of those polaris ranger / john deere gator. They are sturdy cables, typically quite long and work as push pull.

Good luck and I hope your wife has life insurance on you.......

Do this right and build the frame from scratch instead of super glueing a frame to an existing shifter kart....

Show us videos when you run it. </div></BLOCKQUOTE>
If I had fsae funds and resources available to me I would. I have talked to several of the people that have build these types of karts successfully before and not one of them have built the frame from scratch, not one.

600cc gokart, 600cc converted raptor,five other quads, Manx buggy and a 550 (replicar) with stuff stacked on the trunk lid and an SUV behind the 550. Spoiled kid or do you have rich boy hobbie problemshttp://fsae.com/groupee_common/emoticons/icon_smile.gif

the kart is the other guy's...the GSXRaptor and the orange 350R are mine, the other quads are for the family, and my dad and I are building the Shelby Cobra 427 replica, not a 550. The Manx is old and just for kicks.

I've worked my ass off to pay for these expensive hobbies

This makes me LOL!

Anyway, cool projects. I really dont know why, but I think I'd have more fun with the 600cc Raptor though. probably because I'm used to a 600cc FSAE car that can actually use that power...
