Hey guys does anyone know if a 500 4 stroke will fit in the frame of a 400 2 stroke Scrambler without alot of hacking and choping.I know the part number for the frames are different but they do look the same.Has anyone done this swap before?Thanks for the help....Mike

 

Why would you want to swap motors? To make it work you would need more than just the motor.

 

I grenaded my 400 and broke just about everything.If i can get a wrecked 500 cheap enough i think i would prefer to run a 500 over a new 400 2stroke.If it will fit.

 

I would highly advise repairing the original engine . I understand that you are wanting to save money but it rarely is the case after it is all said and done .

If you want a 500, buy one in good condition and part out the 400 . Another thing to remember , when resale time comes around for an engine swapped machine you will lose again , no one wants a "spare parts mongrel" .

Just my 3 cents for free ~

my scrambler blew and i want to put the 500 in it also

 

You can find decent 400 motors on ebay pretty cheap.

 

i am rebilding the 400 and puting it in my lawnmower, but want the 500 in the scrambler

 

probably going to be alot of work but I wouldn't think impossible

take alot of notes and picture especially helpful if you have a digital camera
take alot of measurments of both your old machine and the donor
such as clutch offset clutch center to center tilt on the engine
anything else you can think of along the way

also post some pics of your progress and keep us up to date

if you don't want to attempt the swap sell the whle lot of parts to me I will try it
