Report your UTV rides here. Please post as much information, location, pictures, etc..as you can. Post Riding area inquiries. Find out where to ride that UTV!
Any info would be appreciated as to where around Midlothian TX DFW area that I could take my own UTV to ride. I’ve done some google searches but am coming up short. Thanks
Difficult to troubleshoot remotely. Things I might check. Take a look at the ignition system. When an engine is under load, the ignition system can breakdown. The fuel pressure dropping to 20psi makes me wonder why. It's an elecric pump and unless the voltage drops, it should maintain 50psi per the specs. That port may be a port to measure fuel rail pressure. But you could have a vacuum leak in the iintake manifold or the ductwork to the air filter.

Bit of background. First the machine would take for ever to start. So I adjusted the valve shims into spec and made sure the timing is correct. Starts perfectly now.
now it fluctuates on idle. Bogs down, Revs up, repeat. I noticed the fuel pressure drops from 60psi to 20psi while that happens. It also bogs down at the lower end of each gear, higher rpm seems to be fine. Seems to struggle under load. In neutral it revs up perfectly.
brand new fuel pump, fuel filter, gas. I noticed on the fuel pressure regulator there’s that vacuum nipple, it’s not attached to anything and I’m not sure where it would go. Possibly the problem?
Another issue is the tip off the end of the exhaust is broken off, sensor is still attached and connected. Could that cause these issues?
my next plan was to look into the pressure regulator and voltage to fuel pump while driving. Is there anything I’m missing or any ideas you guys have?
thanks!
Hey Joe,
Don't know if you like Bluegrass music. If you do, got a band and song you should check out.
Band is "Grandpa's Cough Medicine" song is "Brand New .22"
Grandpa's Cough Medicine is not your traditional bluegrass band. But I really like them. Also Pinebox Boys.
Later
Greg
