TRX 300 vs. 300 EX engine swap

A few years back the cam sprocket broke in half on my 300 ex and it has gathered dust in the back of the garage since.Recently I saw a motor for a 300 EX on Craigslist for a low price not to far from home and went to buy it thinking a quick swap has me riding again. When I got there it was out of a utility 300, and was shaft driven. Can I swap this over to sprocket easily until I can get my other motor looked at or should I just clean it up and sell it on E-Bay ? I also bought a gas tank from that same quad but it doesn’t fit right either. thanks guys.

Need Help

Hey guys I have a 2007 sportsman 500 H.O is just stopped working one day. The bike wouldn’t roll over, fuel pump wouldn’t cut in or the gauge lights wouldn’t light up. If you left the key ahead after a while it would light up and you could hear the pump cut in but it would roll. I took it to the dealer and they replaced the ECM and now it all works and the bike will roll and start for about 2 seconds and cut off again. Any suggestions?
