NooB need help. Common one cylinder misfire


Recommended Posts

i have checked everything possible and cant figure it out. just ordered new reeds to replace old ones not sealing well. any info would be great. yes i have searched this great site for all related issues. carbs super clean, both coil leads have strong spark. bike ran great then sat for 4 years. i just changed the carbs to another set of factory with the TORS eliminator cables. i have like to youtube video on my sig.

thx to all replies. i did un plug tors brain, i did swap plug wires and plugs same thing. today i took off cylinders to inspect them and pistons and rings. everything looks great hardly any wear and top end was done 6 years ago. i ordered new reeds. i strongly beleive that the right cylinder reed is leaking and flooding chamber. i did look at reeds today and i can see a gap on them not sealed closed. last but not least left cyl comp 120 psi and right 115 psi. let you all know when reeds arrive.

Hey, this may not be helpful towards your problem, but i had a similar thing happen to my banshee where i was getting spluttering coming out of 1 cyclinder, turns out all the problem was the woodruff key was a little loose and wasnt keeping the magneto spinning perfectly straight , may be worth a check maybe it corroded a bit after sitting thier for 4 years?

ok went thru carbs again and slides correct for each side. floats fine. did notice one jet wrong and also found out springs on idle screws too long. prevented idle screw from touching slide. got both cylinders firing and seems good. test drive. no powerband :). new reeds not in yet? suggestions.
