search the internet for kx500 tecates.  I know there used to be people putting k5 motors in these frames.

I love my KX500 as much as anyone, but wouldnt it just be easier to paint a Quadzilla green ?   You would have a two stroke 500cc factory built quad, Paint it Green throw some Kawasaki stickers on it and spend your time riding.
 I am sure that I stepped on someones toes here, but no need to reinvent the wheel,because the end result already exists.

i have a 1987 quadzilla that stewart and me are planing to put a full mod. k5 motor in . not sure what color i will end up painting but a big frame like the zilla would look godie lime grenn . sorry but i am thinking black with lime green saran wrap and then clear coat . but when we get started we will keep everyone up to date .

Sooo many have tried this, its always a better idea than it turns out to be.  Without a counterbalancer the quad frame will not let the KX500 do its thing harmonicaly.  People seem to keep trying regardless though

I really like mine . I havent had it in the sand yet but I am sure it will do great When sitting and reving it it has a lot of vibes but they are not noticable when ridding it. eventually I will have Steward built me a crank and piston which should make it perfect.
Nothing else runs like a K5 they will eat a LT500 as far as putting one in a Lt500 they are so big and heavy its become a popular conversion to put the LT 500 engine into the Lt250 frame.
So in my opinion The Tecate is the perfect home for the K5.

It may seem like that for now, but go on just an average dune ride which will include a few passes up the hill and you will break/lose components.  The balancing of the motor trick has been tried by many also in the past with poor results. I would only build one if it was for a dragstrip.

I want one in a new kx 450 quad.  Now that would be one bad bike!

I have a k5 in an old lt250r. Im sending my motor to stewart, im confidant all the vibrations will be gone after that fixing this argument once and for all. I will keep you guys posted when i get it back.

My Dad put an 86 KX500 in a Tecate frame. It only lasted one trip to the dunes before it was dismantled and put back on the bike. One problem was he modded a factory kx pipe with pieces of a factory LT500 pipe and it didn't really work right. You had to rev it too much for power. Then, on the first ride, we lost at least three bolts in motor mounts. I also don't think a Tecate is a good platform anyway. The speed and power of the K5 easily exceeds the suspension capability of the Tecate. That's my .02 on that subject. As for the LT500, my Dad has one of those, and it is a sweet ride. FMF Gnarly, VForce reeds and Trinity porting = big grins. :-D

Ive had mine running for a full season now. I havent lost a single nut or bolt. the lt500 is a heavy pig in my opinion, you have to sink way to much money into it and it still dont have the power the kx puts out stock.Not to mention that its always breaking down too. Dont want to bash on anyone here but do the research and time and it turns out good.

I am positive this is in the wrong forum, but what is the difference between the LT500 frame and the LT250 frame?  And what is the balance problem that has not been solved with the conversion with 500 engine ?

The lt500 is very heavy, Its just a big wide bike. The k5 doesnt have a counter balance in it. They do vibrate, but stewart has the cure. The lt500 you have to sink ungodly amounts of money into to make that same power the k5 makes stock. It was i dog and was troublesome, blowing head gaskets and what not. Not trying to bash anyones bike, but its just something that didnt make sence for me to do anything with the suzuki motor.
