ginger Posted January 3, 2012 Report Posted January 3, 2012 So after a long stuggle, i had my shee finally jetted right and the thing was fasttt. i rode it a few times after and it still ran fine. last monday the 26th, it was breaking up a little, but not terrible and it would clear out. Well yesterday i went to go ride it, and it was rich as hell. The weird thing was, when i tuned it, it was around 50 degrees, and when i went to ride it yesterday, it was in the upper 30's. If the tempature did anything, it should have leaned it out. I didnt touch the carbs on it between the rides. Anyone have an idea on whats going on? Quote
Phelps Posted January 3, 2012 Report Posted January 3, 2012 dirty air filters, fouled plugs cause you might not have jetted it as close as you thought, breaking down ignition, or loss of compression from being jetted too lean and it's going down hill. Quote

Phelps Posted January 3, 2012 Report Posted January 3, 2012 maybe try trimming the plug wires back. what is our mods and elevation? Quote
ginger Posted January 3, 2012 Author Report Posted January 3, 2012 I trimmed one wire not the other, but i think its a carb issue. mods are: mild dune porting unknown who did it. cool head with 21cc domes bored to 65mm (not that it matters) toomey t5's k&n air filter, billet water pump impeller i have a timing plate but havent installed it yet. 180ft elevation temp is around 35 degrees.

Phelps Posted January 3, 2012 Report Posted January 3, 2012 jetting is probably pretty close then. only thing that could be happening is the float lvl set too high. jetted it on flat surface i assume and now that it's jetted you are riding in rough terrain and causing the floats to bounce and overfill the bowls. just merely a guess though.

ginger Posted January 3, 2012 Author Report Posted January 3, 2012 will my clymers tell me how to set the floats at the right height? Quote
Burke Posted January 3, 2012 Report Posted January 3, 2012 We went through this issue over and over again a couple years back at the dunes and it turned out that the corners of the reeds were rolling up. Quote
ginger Posted January 3, 2012 Author Report Posted January 3, 2012 could that happen on new reeds? i did reeds when i did the top end. Quote
Burke Posted January 3, 2012 Report Posted January 3, 2012 shouldn't happen on new reeds, but if you pull the carbs to clean them or anything, you could just shine a flashlight in there and take a peek to see if they are sealing all the way Quote
camatv Posted January 3, 2012 Report Posted January 3, 2012 to lean from to cold go to 320-350's/ Quote
ginger Posted January 3, 2012 Author Report Posted January 3, 2012 to lean from to cold go to 320-350's/ trust me not to lean, it smoked like a bitch. and wouldnt clear out Quote
Boone Posted February 5, 2012 Report Posted February 5, 2012 With my mods.... 30 pilots and 300 mains will take me down to about 15*f. If I have to install 310's... I stay home. Don't even know why I bought them Clean Everything check your floats, reeds, air filter, (outerwear if you got it... mine cause me run-ability issues all the time. Amazing how fast them bastards clog up), and move on down the line. You'll finger it... just takes a minute. Quote
