randytbo Posted October 17, 2009 Report Posted October 17, 2009 when im riding along with my shee slow with a steady throttle it will run smooth for a bit then it gets kinda rough. if i take it into the powerband and then back down its good again for a bit. is this a pilot problem, needle setting, or sync? my main is a size to big. my plug is dark brown. it also has a bog off idle. second question i wanna paint my rusty chrome headers black. how do i do that so it will last?

SAVAGE420 Posted October 17, 2009 Report Posted October 17, 2009 Well first off what carbs are you running, stock 26's right? Do you know what pilots are in there? 25, 27.5 or 30's? Know what position your clips on your needle are at? Temps, altitude, mods? Has it always run like this or just since its gotten cold out? I would start with at least eye ball syncing the carbs, and get it as close as you can. How do you know your main is right on? You do the proper plug chop? You richen up some now that its colder up here? With the pipes, i would sand blast them up real quick, then hit it with 2 coats of high heat paint or PC! Quote
randytbo Posted October 17, 2009 Author Report Posted October 17, 2009 it seems to work a bit better since its gotten cooler. i have 27.5 pilots,air screws 2 turns out, not sure about needle im gonna assume stock setting, 290 main a bit rick i think. plugs are dark brown after a ride. i have a trail port, shaved head, air box with lid and 8 1"holes in it, +4 timing, fmf gnarly with pc 2's stock carbs. it works awesome when i wanna go fast but slow is a diff story. 125psi on each cylinder Quote

I would start by just syncing your carbs and see if there out by a few mm and what not. Being colder out will lean your bike up some, making it seem better. But thats the thing, a motor always seems like its running the best and making the most power just before it melts down. IMO you should do a proper plug chop also. http://www.dfn.com/benkaren/plugchop.html Do every step to a "T" and don't miss any steps, or its kinda pointless. Also pull your slides and see where the clips are at. Quote
randytbo Posted October 17, 2009 Author Report Posted October 17, 2009 alright im headin out now to check it all out. what do u think my clip should be at? im just over 2000ft Quote
SAVAGE420 Posted October 17, 2009 Report Posted October 17, 2009 Yeah, just go make sure your carbs are pretty well synced. Then pull the tops of the carbs off and see what clip the needles are on. Here is a good lil clip to watch to sync by eye. Quote

SAVAGE420 Posted October 17, 2009 Report Posted October 17, 2009 got em apart and the clips are in the middle. should i stay there or go up one? I say go up one clip on the needles if you know your a lil rich on the mains. Go try now and check back man. Make sure everything is ok before getting on the gas hard. Quote
randytbo Posted October 18, 2009 Author Report Posted October 18, 2009 well i thaught i just about had it now when i touch the throttle sometimes its like i hit the kill switch off and on real quick. could this be a tors problem? im hardly hitting the trottle hard enough to move the slides. Quote
SAVAGE420 Posted October 18, 2009 Report Posted October 18, 2009 Are your tors hooked up? If so unhook it all anyways. So unplug them both (wires from the top of them) Unplug the lil black box under the tank on the left side then unbolt it and smash it on the ground. Unplug or cut out the wires from your throttle housing. Cut out the wires from your "E" brake. Done. See if thats your prop...... Quote
