Haha i heard that i few times now.Well yesterday i did a new try to check the ignition timing ,but i could not get the timinglight to work on cyl 2-3 again .It works at idle ,but not when increasing rpm to check the advancemark.Not sure why ? maybe the picupcoil for 2-3 is defect ?

I adjusted the timingplate a little clockwice and the 1-4 is now spot on nr 2-3 is a little out on idle .Will try to check more today ,but not happy with letting the bike idle and maybe glacing the bores so i may just ride it more before more checking

I now have got the timing/strobe light to work on cyl 2-3 at 2500rpm. It was just to put the timinglight to the plugwire to cyl 2. I read somewhere that on this type of coils one ht lead is positive and the other negative so maybe that was the reason the light did not work on cyl 3 ht lead. I thaught the left pickupcoil needed a little adjustment since i adjusted it back in september when i used a test bulb to set the timing and just a day or 2 after that one coil melted.So the main timingplate is now turned clockwice back to the setting i used when a coil melted. After what i have understand the coilmelting has nothing to do with ignition timing??  So now both sides are spot on timingmark at 2500rpm.
Yesterday i was for a ride again and it was only about 3degree celsius so i had to have the choke on for the first 10-15 minutes  or else it almost stopped that is not good because it both sot down the plugs and may wash down oilfilm in the bores not what i want when running in the engine. The bike almost stopped at one time and i guess it was because of fouled plugs.
Later checked the plugs and they was sotty, but bike runs good. I then replaced the plugs .Im hoping for varmer weather so the bike dont need so much choke and i can take a look at the plugs again.After replaced the plugs an engine was fairly warm it started popping a little from exhaust .i knew cyl 2 downpipe was the hottest so i turned the micture screw on that out one quarter and after that the popping stopped. I think it is a little lean on all 4 now so will later try to adjust the mixturescrews a little more out. I had set the mixturescrews same as before  overhauled the carbs this winter,but
since  replaced them with new screws i think the settings dont match now , also did a valvejob so that also make things different i think.
