got my sprockets yesterday.... that was fast!

 

didnt even think of that. bb shows them. i had no idea i was missing those fender reenforcement. i guess thats another $25.

 

Well turns out running a quadsport, like many other machines, with a shredded oil pump is not good for the motor. Anyways my 87 quadsport is in perfect shape other than a seized crank and torn up case. I am looking to drop a new motor in it for cheap. I dont really care weather it is stock or not i just want it too move... The faster the better.

Any suggestions for a motor that pretty much drops into place?

 

what kind of riding? racing id say find a 2 stroke dirtbike engine or a 250r motor. if you trail a lot, a big 4stroke motor. but as far as i know, the only other engine thats a drop in is the lt250s engine. others have put in different engines but they had to modify them.

 

Mostly aggressive trail riding. I still wouldn't be turned off of a 2 stroke but 4 would be better. I can make new mounting brackets and some other modifications. I will keep looking for a nice 4 stroke and see if i cant jam it in some how.

 

i trail ride myself. id for sure look at a 4stroke of some kind. i hate water cooled engines so id be down in the 350-250 range but thats just me. good luck on your search. sounds like a fun project.

 

I agree I am an air cooled fan all the way. I like simplicity. I will see what i can find. Thanks for the help.

 

Drilled my sprocket



Removed 3 square inches of steel. Don't know what its worth, but its an edge

look and see what you can find for a honda 400ex engine. its air cooled too but best i can see, that bike is pretty heavy. maybe that big engine in the small 230 frame would be a monster.

that thing looks awesome. im curious to know what your 230 weighs. youve made a lot of weight cuts.

 

I think I had it down to 315 or so, but I'm sure its up now due to longer arms and swinger.

I weigh all the parts a long time ago.... I think the frame was around 20lbs and the engine around 30-40. Where does the other 250lbs come from? lol
