Had fire start in muffler due to failing fuel pump &/or fuel pressure regulator. Must I spend the $750+ for a new assembly from Arctic Cat?!? Here's what I've tried so far.
Replaced fuel pump & regulator - both from Quantum. PSI is 60 rather than the 42 the dealer advises it should be, so problem persists. I've now twice replaced the Quantum regulator & discussed w/ Quantum. They advise that they don't have an alternative regulator that would bring PSI down to 42. I've tried several in-line, adjustable pressure regulators but they either didn't work or I couldn't get a constant pressure from them. FYI, I've only tried the adjustable regulators for Fuel Injected engines however, it seems that they require vacuum to function properly. When I can temporarily get the PSI right, everything works great. Anyone else ever dealt with this problem, and, if so how did you fix it? Perhaps I should adapt the fuel system to include a gas tank return line?
Any insights are greatly appreciated, Don

I finally got around to working on the TRX, this has been an ongoing problem with this machine. This is a machine that we keep on my Fathers property, i dont see it that often, my brother haad it professionally repaired last year and year before same problem, the new starter gears and bypass gears last about a year and the machine is not used that often, he said he was done with it , so i thought i should go take a look. Sure enough the gears were all malled again.
IMG_4910.mov There is some slack in there but most is taken up by the gear cover,if anyone with history with these machines has had the same problem, let me know your findings. Where i am now im looking for finding replacement honda gears on Ebay and try those. I suspect the original was replaced with aftermarket gears years ago and they just worse quality as the years go by.

My grandaughter has a KXF 50 that has no spark. The starter also will not engage with button but works if straightwired. I have checked switches with meter. Does the starter circuit run through CDI box?

Okay, so I have a 2002 Rubicon 500…bought it last year and it sat for several months until I put a new rear axle in, FINALLY got that done and was super excited to finally have my wheeler going, just to notice a strong gas odor. Popped the seat off and sure enough, pouring gas from the carb overflow. Fast forward a few more weeks and get the new carb and get it in, no leak! Yay. Except now I have no spark. 😒 I’ve tried another plug and checked and am getting no power to the coil pack. I’ve read and read and mostly what I’ve found is ECU, which is fine…but I like to exhaust all avenues before buying the more expensive parts just because I don’t wanna spend the money and it have ended up being something simple that I overlooked because I was trying to rush. 😂 I don’t know if it’s relevant, but I read on another post that someone had similar issues with theirs and it was the sensor on the side of the carb, just a thought since this literally happened after I put the new carb on. It also displays “- -“ on the display screen where it should show the gear position.

So i bought a chinese carb and in messing around still trying to get it to run right i figured id pull the spark plug to see if it was running rich, well it was definitely but also i have a nasty mark on the strap (i think thats what its called) that looks like the piston has been smacking it. I never actually pulled the plug because i had it running for a second on starter fluid when i first bought it and was just stupid and figured whatever was in there was good. The part number on it is DPR7EA, which is similar to what is called out for in the manual but i assume the little bit off that the code is means it must be a bit longer or something. Unless the plugs are made like this, but i can pretty easily see that metal has been pushed away from the area of impact. What are the odds that my piston is trashed now you think? It does still run just not well due to carb issues but thats a whole other problem.
Actually i just took a second to google both plugs and it says the reach is the same its just different resistor values and gap size, so maybe the bigger gap is why its hitting. Either way the actual one for it is on the way and i hope it just didnt do to much damage. Wish i woulda just went over the whole thing like i normally do with this stuff.
