just to follow up ...I sidegap my sp, open pipe (musashi long wit small elbow) the rest is stock, bike is at 2400km odometer,..now the fun part is that sometimes the rear tire drifts just slightly but gets back on track i guess at high speed & high revs passing uneven road, sometimes it does happen when i'm coming out of the turn(curve road), this never happened to me on stock cdi, but on namban often & can be sometimes scary cuz feels like loosing control of the bike, when i rev the throttle it is very responsive, it just kicks the bike forward. I also installed a switch tapping the fan & i turn it on when in traffic, I gain a lil 10kmph on my top speed, me plus my wife= 180 kilos + mags with 70-100-17 rear & 90-80-17 front used to go about 85-90 kmph now i can hit 100kmph, i want to try rextor or brt to enable the tps (wit the 2nd socket) & the carb accelerator pump maybe the ride will not be so rough, or maybe just plug in a bigger carb & forget the tps & see what happens...
but surely for the track & circuits this namban cdi is a must try..its a lot of fun...
