i was wondering if its possible to put an 87 jug on an 86 bottom end or if not does any one know if i can buy an engine and just put it on an 86 frame or a lt500 engine cause i need 6 gears

 

None of the jugs interchange. Putting in a later model motor will require frame modification. LT500 motors only have 5 gears. If you put one in though you would not "need" 6 gears.

BTW

Why is it that you need 6 gears?

 

thanks but isint the engine sizes the same so i would to cut the frame or just get new brakets and im really interested in a hibrid 250 frame with the 500 engine would you recomend an extened swingarm if i went through with the 250zilla

hello there why not just pick up an older triple cly snowmobile engine and slap that in.boy would that thing go like a bat from hell....

 

The 87 and later LT engine does not fit well in the 86 frame, but the zilla engine goes in with very little modification. You WILL need to extend the swingarm as well as the A-arms and the front shocks, but a properly built 250/500 hybrid is a very formidable weapon.

 

I'm running a 14 tooth front sprocket and I often find myself in 5th looking for another gear.

 

You can probably get a bigger front sprocket than a 14. A LT500 uses the same type front sprocket and comes stock with a 13 so I would expect they are made at least up to a 15 tooth. If not you could go to a smaller one on the rear. What all have you done to that 86 LT to spin a 14 tooth gear. Mine had the stock 12 tooth with smaller tires and just barely had respectable acceleration with that. It didn’t have too much done to it though. Just a FMF silencer, K+N filter and a shaved head.
