As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault! I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

I need a pair of front shocks for a Landpride Treker 4200NT, from 2005? Does anyone know of a good salvage yard - or another source?
The old shocks have "SEBAC 11685 12 3" stamped on them (or something very close - it's hard to read). I think SEBAC are (were?) an Italian company.
Is there a compatible shock I can use? I don't have easy access to a scrap yard where I can compare shocks etc.
Thanks,

I have a 2017 Intimidator XD4 800cc 4x4. It will run great and then it's like it goes into safe mode and only runs on 1 cylinder. It's not fouling out the plug when it happens. Some times when I stop and restart it, it works fine. First I thought it was a spark issue, then a fuel issue, but I feel like it's a short in the wiring some place.

I swapped out the Subaru motor for a Predator 670cc. If I remove the heat shield around the muffler, The stock muffler sits in there just fine with 1" to spare.
Only problem is the exhaust exit is toward the back seat instead of out the back.
Do you all think that the stock exhaust would be okay (just as effective) if cut a hole and welded a pipe on the reversed (opposite) end? Of course, plug the old exit end. Other option I thought of was to roll a tube 180° with a 7" center line radius and finish extention of 12" or so.
Any thoughts?
