ben... i was wondering when you would chime in on this ha. you're bikes lookin sweet. good job on that tank.

i'm assuming that link was supposed to be to bdk's site. they have amazing stuff there. 98mph crazy!!! i emailed them actually when i was looking to get the 93cc kit, but their communication was iffy at best, and they have yet to return my last email about buying parts.

and yes shipping was insane. the kit was 67GBP ($110). shipping was more than the kit itself at 97GBP ($158). i hope this thing is worth it.

about the pipe. yeah i'm only looking to be able to actually PULL up to 70. dont want to have to wait all day to get there. so no need for a super high rpm pipe. i'll stick with this one for now.

i think i'm gonna repaint/powder the whole bike with a black and yellow paint scheme. i'm thinning my flock of bikes down, and going to keep three: the yellow/black garelli, the ar (soon to be yellow/black), and my tomos (also soon to be yellow/black). keeping it consistent.

ok cdi and timing explanation. it's kind of complicated and long, but here goes. back when i was bump starting it, i lost my spark. whether it was from the actual bump start and the jolting involved with that, or just vibrations from riding, i dont know, but the nut holding the flywheel came off. then one time when i tried to start it, it backfired and the spark was gone. i took the flywheel cover off and realized that the nut had fallen off, and the flywheel was spinning freely on the crankshaft = no spark = sheared woodruff key. so i took the flywheel off and realized i had sheared the woodruff key, which is really just a pin like on tomos crankshafts. not having a replacement handy, i eyeballed putting the flywheel back on. i tightened the nut down and found a mark on the flywheel that is supposed to line up with a little arrow on the case to indicate if your timing is right.

i got out the timing light and the two marks lined up perfectly with the strobe. i assumed all was kosher, put the flywheel cover on and rode off into the sunset. little did i realize at the time (in my early and seriously lacking timing skill and knowledge) that these marks would ALWAYS line up if i didnt change the position of the stator plate - even if i attach the flywheel 180 off. so in theory, if i put the flywheel on and line up the keyway in the flywheel on the OPPOSITE side of where the key would sit in the crankshaft (essentially 180 off on the crankshaft) the two marks on the flywheel and case would STILL line up at spark even though spark would be happening close to BDC. this is due to the sparking mechanism being independent of the crankshaft, and only depending on the position of the flywheel and stator plate.

i hope that makes sense.

so after i blew a hole in my piston, i realized my error. I checked the timing last night and it was set at about 3.8mm BTDC when stock is 2.3mm or 20 degrees. I set it to 2.3mm and she seems to like it there.
