By HISUN Sector 750 EPS Failu
"Mrs. Smith" doesn't like how loud our Sector 750 is. On a HISUN forum someone said the same thing about his 750. I haven't given it much thought because I've been more focused on stuff that has broken.
So, I used my decibel meter to check ours out. 4000 RPM, Low gear, under 20 MPH . . . . 97 decibels. That's above most ordinances, even state boat noise limits.
AI Overview Ninety-seven (97) decibels is considered very loud and dangerous to hearing with prolonged exposure, roughly equivalent to a newspaper press, a loud nightclub, or a snowmobile. At this level, damage can occur after just 30 minutes, necessitating hearing protection -

I just bought an older (2008) Teryx 750 and am having some concerns. Hoping of course, that most are not too big. . . but more knowledgeable folks like yourselves will surely have some ideas. Thanks in advance.
-- about 2700 hrs, camo version
-- Starting: after not running much at the auction site, I tried it and it was tough to start but half of this was likely I did not quite know the tricks for how long to keep the choke on. However, once it started it was kind of hard to keep running until it warmed up(once warmed it starts perfectly every time with no choke). Now, back to running after the first ignition: I had to hold the RPM's up a bit to keep it running and when doing so it sounded as if a little gnome was inside the engine pounding on something at random intervals. Wondering if this could be detonation-- "knocking"? After warming, it disappeared completely. Maybe just need higher octane gas??
-- After starting and running a bit there was a pretty terrible smell, most "like" burning rubber or an electrical fire. No fire or resolution of this. Eventually this TOO went mostly away, but still basically present. Could it be adjustment needed for the main belt variable speed tranny?
-- When I move from neutral into either Lo or HIGH range forward gears, I get gear clashing. I did NOT put foot on brake and read in manual(just NOW) that you are supposed to do so. (I have NOT gotten back out to check and see if this matters. ) OR, could it be part of the drive system is mashed up??! Geez, hope not.
-- There is a big open hole allowing direct sight into the belt transmission on the back right side. This can't be normal, it must require some plastic cover. Right? Any rodent could get right into the transmission!
-- THere appears to be no muffler or spark arrestor unit. This "could " be the cause of some of the smell. . . ?? but that should not smell like burning rubber or electrical smell. . .
SO. That is all.
I sure would appreciate any insight on this issues and finally(!). . . if I was to take this into a local dealer what would you say are the top three issues I should have them address first?
thanks!

We bought a used American Landmaster TW450 with a Fuel Injected Kohler 440 on it. Today, I bought a Predator 459cc 15.8hp motor from Harbor Freight. But before we put the new motor in, it's pretty obvious, the stock throttle length is NOT long enough. The stock throttle cable from gas pedal to the end is only 32 inches!
We need at least another 10-12 inches to get to the throttle linkage on the new motor. What can we do??
Is there some way to modify the original throttle to add some length? Or do we have to buy a brand new cable?
