new pipe, new problems

[danlt73]

ok i got me a wb e2 pipe, i also got a k&n, and i jetted the bike, well earlier today i was riding in a construction site behind my house, when i go up this hill in 2nd gear, the bike seems to lose all its power and wanna stall, i have to drop it to 1st and almost redline up the damn hill, it never seemed to have that problem before, also when i rev it in neutral, i push the throttle fast and the bike sounds like its choking, damn! im ready to give up

am i running too rich? too lean?

Sounds like it could be bogging down cause its to rich maybe... But what is it jetted at now? And pull the plug and tell us what you see.

im running a 150 dynojet, ahh im gonna have to take the plastic off to get to the plug

a simalar tthing happend to me and it was my main jet that fell out

[boricua]

why do you have to take your plastic off to get to the plug?

[Halter]

plug is pretty tough to get too...

The only thing that needs to be removed to remove the plug is the boot:p

I use a regular 18mm deepwell 3/8 drive socket and short extension. Fit the socket on the plug first, then add the extension and ratchet. Works everytime:D

its gonna be a tight fit, good thing i just bought 32 sockets from my local wal mart for only 3 bucks! damn i love it there, haha:D

ok, i took the carb out, (im bored), plus ima tweak the jetting a little, i removed the choke, now im pondering.......will polishing the carb's inside make a difference?

Your quad should have came with a spark plug socket in its little pouch in the canister by the battery. Pull off the plug wire, insert socket over plug, then use a screw driver or something thin and round and insert it thru the holes on the socket to turn the plug loose. The color of the plug determines how rich/lean it is. White means lean, dark black or wet black means rich. Your aiming for a nice brownish-gray color. If the quad bogs down, you're probably running rich. Too much fuel means no response. Now if you hit the throttle and it goes but feels like it's starving for gas, you're lean and you need to increase the jet size. Regardless, if you are only having problems while riding at speed, it's the main jet you need to focus on.

what an idiot, haha i totally forgot about those tools :cuss:


anyone have any thoughts about polishing the barrell of the carb?
