My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area.
Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

Hey all!
I recently acquired an 02 big bear 400 this past summer, carb on it was shot to sh** (pics attached) so my father recommended I just buy a new one off amazon. I purchased the first one that came up as compatible and once it came in, I bolted it in and it fired right up with no noticeable issues. Once I got to the trails with it I realized that on any un-level ground, there's little power output. I checked with 3 different local shops and they all refused to work on tuning up off brand carbs because of how terrible they are. One shop had a motorcycle in with an aftermarket carb and the mechanic said that that would be me if I brought my big bear in. Whoever owned the motorcycle and needed their aftermarket carb tuned up had racked up the bill to nearly $1500. Needless to say he made it clearly obvious that putting any amount of money into an aftermarket carb is not worth it. Now that I've learned all of this, I'm wishing I didn't toss the old carb for a $30 amazon one. In light of this minor f-up does anybody have any recommendations for high quality carbs for my vehicle? I've also attached pictures of the old carb and its condition for your curiosity, although its current condition is likely 6 feet under in a landfill somewhere.

I found this one on EBAY that advertises as a genuine OEM part for a fraction of the $650 that they're normally worth. Any help would be greatly appreciated, thanks!

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 have a 99 Yamaha bear tracker and I have converted the front brakes from drum to disc fairly easy but I cant figure out how to convert the rear with out hacking apart the rear arm. tried to use parts from a wolverine since the rear arms look similar but the caliper mount didn't line up on the bear tracker axle. Can anyone give me any clues or has anyone successfully converted the bear tracker rear brakes. I would even purchase a conversion kit if there is one. Any help on this would be greatly appreciated.
