06specialedition Posted August 5, 2011 Report Share Posted August 5, 2011 Okay guys I'm having an issue that is driving me crazy. I've been on the phone on and off all today with Brandon and Shay from Wildcard Racing trying to figure this out. I'm running stock carbs on my duner and the other day I took them off and cleaned them. Threw them back on and the left cylinder is barley running. After going through everything Brandon was thinking its maybe a pilot circuit problem. Maybe a clogged pilot jet? When I pull the choke half way out the bike runs normal like it should. But when I push the choke back in, the right cylinder runs normal and the left is barley running. I don't know what to think the fact that it runs better with it at half choke than not. Before taking these off and cleaning them the jetting was setup perfect for this motor. I haven't checked for a clogged pilot jet yet. But I'm willing to take ANY SUGGESTIONS at this point? Thanks!

Surfrjag Posted August 5, 2011 Report Share Posted August 5, 2011 well first i dont consider myself an expert, butt... take that problem carb off and reclean it asap. if pulling the choke helps it then it needs fuel and is likely a clogged pilot jet. it is possible that the float is getting stuck and not filling up all the way but unless you tweeked it removing and reinstalling the bowl then its unlikely.

06specialedition Posted August 5, 2011 Author Report Share Posted August 5, 2011 well man.. if it was running before no prob then cleaned the carbs and it started giving you problems... most things would point to your carbs... In m experience.. people that just spray some cleaner in there and call it good doesnt always do the trick. In some occations I have had to use something to pass through the jet or circuit to ensure its been cleaned. ive seen my fair share have clear white shit build up on the side walls. You could have cleaned the jets but ended up pushing gunk blocking the circuit passages somewhere. if the carbs are gunked up in the circuit and not the jet you may have to soak the carbs in a cleaner for a while then use a air gun to blow the crap out Ive had to do this on my snowmobile carbs in a few occations from having them sit over summer or for extended periods of time then cleaning the carbs and ending up blocking the circuit inside the carb preventing it to even run. just in my opinion man take the carbs apart clean them out very good not just jets but passages too... let the problem carb soak in a solvent if needed for a few hours atleast That is my next step. I need to get my compressor and make sure nothing is clogged. I'm thinking maybe thats exactly what I did, was probably push some sand in the pilot or something. I'm really hoping its something stupid like that. Quote Link to comment Share on other sites More sharing options...
camatv Posted August 5, 2011 Report Share Posted August 5, 2011 if you didnt use a compressor and a rubber tiped blow gun the carbs are not clean you also need to make sure the air jets in the intake bowl are clean and i'd completely disasemble them that is remove the dump tubes and everything. i also use carb cleaner and spray through all the passages and make sure they are clean and going where they need to.. hold the slow jets up to light and make sure you can see the light through them they can get varnish whick looks yellow, buit you can see light through them if blown out with compressed air they will be clean and clear. if a bike sits for more than 30 days with fuel in the tank its gone bad and has started to turn to crap. also you can remove the petcock and clean out the fuel filters.. check your float height and make sure thats correct when you put them back together Quote Link to comment Share on other sites More sharing options...
06specialedition Posted August 5, 2011 Author Report Share Posted August 5, 2011 Just pulled the pilot out of the left carb and couldn't see any light through it. I cleaned it out so now I can see light. I'm hoping that was the problem Quote Link to comment Share on other sites More sharing options...
shanYE west Posted August 5, 2011 Report Share Posted August 5, 2011 make sure the slides went back into the appropriate carbs? Dbl check the cut aways and make sure they're facing the rear. float bowls on the right carb? i'm sure its a simple fix. Quote Link to comment Share on other sites More sharing options...
06specialedition Posted August 5, 2011 Author Report Share Posted August 5, 2011 Looks like it was a clogged pilot jet on the left carb. While cleaning them some sand must have made its way in there. When I first took the pilot out I couldn't see daylight through it, cleaned it and blew it out and now I can see light. The bike seems to be running like it should now....so far so good atleast. DUNES HERE I COME Thanks guys, I'll let you know how it is running once I tear up the dunes this weekend! Quote Link to comment Share on other sites More sharing options...
Banshee Chad Posted August 5, 2011 Report Share Posted August 5, 2011 That's the crappy part about sand, its every where and only takes 1 grain to cause probs.. I like to blow my shit off with air compressor before I take anything carbs related off.. Quote Link to comment Share on other sites More sharing options...
