guys, by the next two weeks, me and my buddies will be having our 3rd annual out of town ride. it seems i'm being the slowest now..i ride a sniper ac..my mechanic suggested i upgrade my cdi and camshaft.. i already got an LHK 1st stage cam shaft and planning on buying a brt dualband cdi. will these be enough to increase my bike's power? the only upgrade i had before is an open pipe. currently my top speed is 110kph. i want to go up by 10kph more and increase acceleration.
what other upgrades can i do on my bike. by the way, i'm not into drag or circuit racing..i use my bike goin to work and some joyride..but still i wanna go fast. hehehe! thanks.
dagdagan mo pa ng vixion valve spring aabot ka ng 120 - 130 kph

Hi Masters, if I will use rextor cdi... do I still have to replace the stock valve spring with vixion valve spring or any rvalve spring to avoid valve float? What if I already have rcdi then with a stock valve spring? Is it still ok? or not? Please advise masters hihihihih ^_^

Thanks god bless

3 C's engine modifaction

C - carburetot ( Big Carb)

C - Camshaft (Racing cams, hi-lifts, low-lift)

C - CDI (RCDI BRT,REXTOR,API,ADRION,HI-SPEED, ETC.)

changing the stock valve springs to stiffer ones is much better to avoid valve floating.

namban user here 1 socket(no tps,heat temp)...color yellow, just got it last week, still under observation, but definetaly better than stock
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...

well that "drift" thing also happened to me during high speed ,,,tru, it was scary...so it was because because of the cdi?i thought i had problems with my rear tire...i also used namban cdi..,but sold it to purchase brt...i hope it performs better than namban....i'l give you an update..

btw, should i replace my stock valve spring to harder one when i change my stock CDI to unlimited CDI?
I heard that its not so important cos my stock engine won't run over 11.000 rpm. valve floating will not appear below that's rpm. is it right?

no need paps because the little chip is the limiter to 13.5k rpm...but if you remove it then literally no more limiter not unless your engine says it has...try to adjust the AF mixture of the carb and valve clearance....meaning tune up...WHY?different settings means different tune..happy and safe riding

thanks a lot paps..the clearance is 10 intake ang 15 exhaust..maybe i will replace my mainjet to 110..
there is a "sinok" on the carb when i rev quickly and remove the element filter..
