sportbike engine into quad - Tilted Forum Project Discussion Community

Knoweffects · 12-13-2004, 02:50 PM

im thinking of starting a cbr600/900 or gsx-r1000 swap into a quad. if anyone has any information, ESPECIALY on kits or frames id love input. i'd like to start with a frame that the engine would fit into with little accomadation and minimal welding. ive herd the lt500's and banshees are good foundations, and that ds-650's are even better.

Umm i've helped people do it with go karts...pretty much drop it in and line up the chain...the fabricate brackets.....i don't know of any kits, but any type of swap is possible.

Knoweffects · 12-13-2004, 08:18 PM

yea possible but ive talked to some people who've ended up spending 1k to put something like a 650 dirtbike engine into a 300ex or some crap like that, some swaps are easyer than others, just wondering if anyone has done a relatively easy one that turned out nicely~ pritty sure there arnt any actual kits, but hey, if there was~....

ok i've been seeing alot of pictures/storys about cbr600, 900, and 929s being put into DS-650's, and they do seem to have the space in there frame for the engine, i think this is what im going to try, if i decide to build it. once again any tips or tricks would be awesome

GetRdone · 12-15-2004, 08:07 PM

as far as i know, it should work with relative <<< key word) ease. Alot of quads share powerplants with others bikes from there respective manufacturer. I think it depends on a couple factors; 1. was the quad a 2 or 4 cylinder (i know some older sport bikes and motox bikes were 2cyl) 2. how much room do you have in the chassis. I also think some other things to consider would be that with all the added power, could the rest of the drivetrain hold up? Good luck, post pics if you get it to work

Knoweffects · 12-16-2004, 12:04 PM

err, 99% of quads are single cyl, and only an extremely small ammount are twin Vs, iv never herd of a i-4 quad, whereas the streetbike engine im planning on useing, ither a CBR 600 or 900, are both I-4's, this is the prob~ altho DS-650's have pritty big engine space in the chassis. drivetrain will hold up reasonably well altho i plan on getting a extended swingarm 3 or 4 in, and a stronger axel, because stock ones always bend to easy~

GetRdone · 12-16-2004, 12:15 PM

hmm i thought most quads had twins, and some had 4's, o well i stand corrected, my bad. I dont think puttin the 4 in there would be that hard tho, assuming there was room. Is the quad motor linear, or horizontaly opposed (ie if its a twin, is it front to back like most bikes, or is the motor horizontal more like cars)? Linear would be the most likely, and if so i think u could pull it off.

Knoweffects · 12-18-2004, 02:56 PM

ive never seen a HO quad, altho BMW has a street quad concept thats a HO engine, anyway what im swapping IN is a I-4, the engine thats comeing out is a single cyl. the positioning will be the same and i think its going to work, i just need to make a few brackets, shouldnt be toooo hard. err, most engines aren't HO, thats pritty exotic, i think you ment how alot of cars V engines have cyl's that are somewhat faceing the sides of the car instead of how say a bikes V is front and back. tho subaru and porche love them some HO engines, and the old VW's were all like that.

GetRdone · 12-23-2004, 02:42 PM

Not quite what i mean. Subaru motors are boxer motors, which i guess are technically horizontally opposed. What i really mean is; on a car like a 3 series bmw, the i-6 motor has the first piston towards the radiator and the last one by the fire wall (front to back). Cars with little 4cyl's like hondas mostly have horizontally mounted motors (ie left to right or vice versa). Thats all i meant, But i understand what u mean.

Weight is an issue. Where do you run? If you're in sand smaller tweaked engines seem to work better. It's been a while but I've seen two 900+cc conversions in Florence. Both sounded great, threw profuse sand clouds, but could hardly get out of their own way, let alone compete with the more nimble quads buzzing around them.

Are drags a big part of your riding?

Here ya go, not a kit or anything, but I took a lot of pictures while I was doing it. Have quite a few more not posted so if you want more email me.

Its a Warrior with a CBR600RR engine by the way.

The engine "fit" in the frame bone stock no modification. Had to modify the upper frame rails to fit the airbox though. If you dont want to have to do this I suggest a Carbed engine rather than FI since all FI engines have very large airboxes on top of them.
