Still trying to figure out my Coleman 550 start issues. I was looking at injectors and I see some with the same applications listed (Coleman Hisun 550) that have 2 holes and other have 4. I don't know which I have now, but does anyone know why this variation exists? At times it seems like I'm not getting enough fuel and I wonder if I'm supposed to have a 4 hole and have 2 hole or maybe the 2 hole has larger orifices to equal the same amount of fuel spray, something like that.

Anyone have any thoughts on this?

      2023 t-boss 550 belt slipping and found oil in belt housing
      By Cory J
      Belt started slipping when I used it in high gear. It works okay in low unless I'm trying to power it up a hill and then it slips.., Ordered a new belt and went to change it and found a good bit of oil in the belt housing. Has anyone experienced this? Belt looks fine. Only have 300 miles on this thing..

      Coleman UT 400 Garage?
      By Homeowner A
      I have a Coleman UTV 400 and looking for something to store it in.  Preferably something vinyl or plastic with its own base that can stand alone outside and house the UTV.  I think the dimensions of the UT400 are around 106" long 52" wide and 74" tall. 
      What should I consider that won't break the bank?

      T-Boss 550 aftermarket suspension suggestions
      By JSwearer
      Does anyone have any suggestions for aftermarket shocks.  I have a T-Boss 550 and took it riding in some rough trails and the stock suspension was uncomfortably rough.
      Thanks

      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.
