R1 motor in 400 frame?

[pnut420]

I was thinking about doing a project quad for sand racing only and have found a few complete R1 motors with carb and everything for around $1,000.

I want to make sure I use a frame that is going to hold up with all this power and was thinking maybe a LT600 frame would be better to with than a 400ex. Is their any other frames that are tougher than a 400ex or LT600?

what is an LT600? you mean LT500?

Yeah LT500. I got mixed up because I saw one for sale called a LT600, it was just a LT500 with a CBR600 or something like that

R1's have carburetors? Are you sure they're not fuel injected? Personally, I think the 400EX frame is too weak for a motor with almost 200HP. Think about it.. The frame was designed for a 400cc 26HP motor.. Unless you do some serious gusseting or modification I wouldn't do it...

Here is a pic of my trx250r with a trubo kz1000. So I would say a 400ex frame could work ...

How long have you had that motor in that frame and it has held up fine?

A R1 motor is fuel injected and for $1,000 it included everything, it would probably take up to much space mounting the ECU and everything. I would probably go with a CBR600 or an older motor.

Shane didnt you have the 250r frame lengthened 12 inches and gussetted. Also how hard was it to mount the motor in there and setup the drivetrain and everything?

I have a cbr900 in an lt 500 frame. I choose the lt 500 because of the size of the frame. They have plenty of width, hieght and length for an easier conversion. I know where you can lighten and where you need to add metal to the lt. I'm sure you could do it with a 400ex or 250r frame the biggest trick is what can be added or removed.

I chose the cbr motor because it was still one of the carburated motors. The 929-954 are efi and I haven't had enough experiance with bike efi controls. Even with the carb motor their are alot of electronics and it takes a lot of time sorting through it all and then hiding it on the quad. I know people that have the r-1, hyabusa, gsx, motors in mini sand cars and they have figured it all out so it will work.

It also depends on what you want to do with it. If you want to just drag it or hillshoot or if you want to play ride it will make a difference how you set it up.

yea i bet u could do that. i would go wit a cbr 600 motor as well. but a 400 ex would be a great target to put a cbr motor in. good luck!

here's mine.

I lengthened the frame but did not gusset it ....

Iwould go with a turbo kz engine it is simple and powerfull....

a 600cc engine will not make enough power

mounting was easy ...

[shaneb]

I also have this one ...

zx9r engine

[Maxxed out]

My guess would be youre gonna crack the 400ex frame in a second!

[oldsandman]

shaneb where do you ride? I do disagree about the cbr600 I have built one and they do go!:D On the flats the cbr600 is very quick but up a hill the cbr900 pulls harder. But you are right bigger is better, their is no substitute for displacement.

[shaneb]

on the 600 it depends on your expectations ....

I think that the zx9 may be too slow .....

I ride at pismo glamis and dumont ..

I am going to sand mountain for labor day ...

Your bike looks nice oldMan !!!

The 400ex frame will be just fine !!!!

So how did you mount the motor, did use modify the pivot bolt on the rear and then have custom motor mounts made for the front? Also how do hook the chain up, did you have to have a sprocket made for the engine or did you have a custom sprocket made for the plus 10 inch swingarm you are running on the banshee. I dont want to have to lengthen the frame either, is their any way I could get away with a 10 inch arm and keep the frame the same length and just have it gussetted for strength?

Also do you have any pics on you working on either one while you were rebuilding it?

If I did a 600 I would plan on putting higher compression, bigger cam, maybe Nos and a few other things but then again by the time I get done with the 600 I might as well run a 900, its just alot easier to get a hold of a CBR600 for cheap.

[shaneb]

I how hold out and go big !!!

It would be nice to have a stock engine ...

It would be more reliabale ...

True. Im not going to do it for awhile and when I do build one Im going to make sure I have plenty of money and do it right the first time.

[oldsandman]

Go for the 900...like shane says it is better to keep it stock or mildly moded. You will have plenty of power anyway and your reliability will be excellent,

Yeah it would take awhile to get used to the power of a 600, let alone a 900. And it is better to stay near stock for reliabiluty anyday, this quad would be my low maintance race quad for the sand flats and uphill drags only

me n crazy casey are gonna be building a drag quad soon. its gonna be a warrior frame with a 4 cylinder motor but i'm not sure which one yet. how do you think a warrior frame will work for a 4 cylinder bike motor? its all we have so we have to make it work but i'd just like to know if you guys think its an ok frame. i think it would do good. its beefy and its fairly large too.

Yeah your warrior frame should be just as strong as a 250r or 400 Ex

Hey pnut, why dont you give him that piece of s**t you call a quad, you know, the one that you left at my house a.k.a the "blaster". I bet you think that frame would work well in this instance too. Sry, didnt relize you you were so knowledgable in this department.:p :rolleyes:

Ww see whos quad is a piece of s**t when I smoke you at Pismo and no Im not knowledgeable on this thats why Im asking Shane:rolleyes: Ill probably see yopu this weekend to pick up the blaster

Sprocket specialities makes front and rear sprockets for what you are doing.

Thats awesome, Ill check them out, I always thought that would be the hardest part. What about the motor mounts any ideas there?

[shaneb]

that is where I get my sprokets ..

motor mounts are easy just tabs welded to the frame ...
