What would be the best sport bike to swap a motor into. I kinda want to stay 2 stroke. But what would be a god frame and a good motor to put in it.

I was thinking (My First Mistake) What about a 300ex frame with a CR 500 motor



What would you guys suggest???????????

 

walsh frame with crf450 seem the way to go if your an MX'er

I would like to put my ds650 motor in a 250r frame![img]i/expressions/face-icon-small-happy.gif[/img]

 

Really wanting to know if a Shee motor will fit in a blaster frame.

And will it be a worth while swap.

 

If not that what about a Shee motor in a warrior frame I know it is a little heavy but with all that extra power it should jump and ride pretty good

 

Anyone have any ideas???????

 

as for the shee motor in a blaaster frame- the blaster front end is light enough that it comes up even with the weak power of the stock motor. so if you somehow managed to fit the shee motor in there you would not be able to keep the front end on the ground. and as for the warrior frame it is so much like the banshee frame that you would not be able to tell a difference. just my opinion

 

My personal fav would be the new TRX450 engine in my 85 250r trike chassis. Although, I still think that an 86-89 TRX250r with a hopped up CR500 engine is the baddest all around ATV you could have.

I have seen a blaster with a KX250 motor in it for sale in MI. It was in the Boat, Bike, RV Trader. You could probably look it up online. The prob with putting the shee motor in the blaster chassis is that the shee motor is a twin and I believe the blaster 200 is a single. That's why the KX250 (or 500) would be easier.

 

I really like the idea of CR 500 in 300ex frame but the CR 500 motor is very hard to find.

 

This might sound a little "far out" but what about a Banshee engine in a Banshee frame???? What on earth would you be gaining by putting a Banshee engine in a Warrior frame??

I'm doing the ultimate swap. YZ490 engine in a Blaster frame. It's the best [read easiest] because I get open class power, the engine slides right in with the motor mounts matching very closely and I don't have to worry about mounting a radiator and all the plumbing.

 

I knew a guy that put a cr 500 engine in his 250r. The thing vibrated so bad it wasnt really fun to ride. It was scary fast tho. If you are doing the ultimate engine thingy, why not get a rz350 motor and put it in a banshee frame or any other frame. That way you stay 2 stroke and have a very badass setup.
