American Sportworks UTV, I swapped in a Predator 670 engine. I relocated the exhaust which was originally bolted to the side of the engine, to the rear of the buggy, via some flexible exhaust pipe. It runs like crap and I think maybe the reason is my exhaust is adding restriction. So I would need to put in smaller jets, right?
Also, the jets installed at the factory are two different sizes. The reason for that as I read somewhere, is that (with the muffler in the factory position) the exhaust gas path through the muffler is longer for one of the cylinders than for the other. I think my added section of pipe might negate that difference. So should both sides be jetted the same now?
Does anybody know where to get jets for this?
I have a Rural King version of the Hisun Sector 250 with about 75 miles and 15 hours on it. It just started being difficult to start and idle. But if I hold in on the gas a little it will start and run until I left off. It also runs good and will run good until I stop then it idles for a few seconds then quits. Its about 4 months out of warranty. Battery voltage is fine before, during, and after starting. Oil is clean and clear. Gas is fresh. I can hear the fuel pump spool up when I turn the key to actually start it, not when I turn it to the on position though like on most other UTV's I have owned. Its really odd and has me perplexed. The only other thing that I have noticed is that the engine temp indicator on the left side of the dash only indicates one bar regardless of how warm the engine is. Other than that, it runs great. Just hard to start and won't idle. Any suggestions? It has me perplexed.
Doing some much needed overdue maintenance on the Joyner T2. Believe mine is a 2011.
In need of :
- wheel bearings and seals (small and large)
Bearing 02.D650.03.01.0005 - 65x35x35
- Inner tie rod joints
- Upper and lower ball joints
and I'm sure I'll uncover a few others as I continue the tear down
What's the most reliable for parts now?
- Casey Ye from China, assuming shipping cost and time would be higher.
- Klung, China contact as well I believe.
- Is ordering from Joyner-USA working for folks?
Address: 1650 E Riverview Dr Ste 110, Phoenix, AZ 85034 Phone: (602) 253-0283 Don't want it torn apart in the shop for too long.
Is there a parts manual floating around for ordering the correct parts? I have a 2009 parts manual I believe, but there are definitely differences between that model and mine.
Hate to order the wrong stuff.
