Hi All,
I was able to get my bike fired up yesterday for the first time in 11+yrs.
The first time she fired up I needed to use ether and a bunch of kick starting. After she was running awhile I was able to stablize her idle at around 1K rpm, on full and half choke. When I go below 1k she stalls, and when I go to no choke she wants to stall, unless I keep the rpms up and then runs really rough w/some backfire. After I got her warmed up she fired up w/a little blip of the starter switch or maybe a quater kick. I must have started her a dozen, or more, times, all afternoon and into the evening. Pulled the plugs and they had a
fluffy black carbon deposit. Today I expected to be able to just start it w/no problems and go on to other problems. Before I tried I pulled the plugs and cleaned them up just to get the best spark I could. I tried to use the starter and ran into a problem I've been having but thought it cleared up when I got everything loosend up after it's long slumber. Since the starter didn't work, I started to kick it...no luck. I then went right to the ether, Bang started right up.
Got her warmed up and everything stablized like yesterday. No problems starting it using the starter and the kickstart. Decided to do a higher rpm test. Cleaned the plugs and ran it a around 4K rpm for about 5 min and killed the power, got a little backfire. Pulled the plugs and they are still black but no fluffy deposit and looks cleaner, more burned than fouled. I haven't adjusted the cam tentioner nor have I done anything w/the valves. The petcock is working correctly. I've cleaned and rebuilt the, Mikuni BS34 carbs, all new jets, including the o-rings and the little screen baskets on the float valves. Stock pilot needle w/no adjustment slots. Floats are bench adjusted to 18.6 +-.2mm. Air/fuel is adjusted 2.5 out from needle seat. Replaced #115 or #112.5 stock main jets w/117.5 and stock #40 pilot jets. Intake/exhaust mods which might effect the system are Mac 2-1 pipes and K&N pods, including crankcase filter. Spark seems weak. I'm getting 12v at the battery when the ignition is turned on and 12.75 w/the ignition off. I'm getting 11.25v at the coil. Am I correct in believing that these reading would indicate that I'm not getting enough juice to the coil, for an efficient spark? WG, do you think your coil mod will help?
I'm so close to getting her back on the road I can taste it!
Any help would be greatly appriciated.
Thanks
