I would think so as long as its not in the red line. does your scoot have a tachometer?

[robb]

I think it matters what rpm you are at, at wide open throttle. Bone stock scooter probably can sustain WOT with restrictive airbox and muffler. If you add a bbk, performance camshaft, upjet, add a uni better cdi and exhaust you will be able to overcome more wind resistance increasing top speed and rpm of operation and heat produced. May be too much to ask of a china engine.

I did put the orange coil and cdi and an NGK plug
no RPM gauge

No, running a scooter at WOT will kill it faster than anything...they are designed to run at about 80% power max with rare exceptions up to 90%.

what doesw WOT refer to?

[royldoc]

wide open throttle.

I rode my 150 cc scoot all last summer,and fall for 20 miles one way and 20 miles back to work. I mostly traveled at speed of 40 to 55 mph (not WOT) the whole way, and never had any problems. my little 150 does 70 mph (according to the speedometer) at WOT, on level ground. I know because, on a empty, straightaway country road, I tried it out briefly. I was surprised that it went that fast. Only tried this once and only briefly to see what kind of speed I could get.

My Roketa MC23 150 speedometer is off by 5 MPH slower on the low end to about 30 and 8 MPH slower on the higher end. I can hit just over 65 on the speedo but GPS verified it's actually 57.

Yes, if you weigh 150 lbs and you can get it to 60 mph on GPS you are WOT...guaranteed

If you made all those mods WOT would not be needed.

What I am saying at wide open throttle you may stabilize at 7500 rpm with an unmodified scooter and it doesn't matter if the carb is wide open or not as that rpm shouldn't be destructive to the engine. If you mod it it may be able to reach and maintain 9500 which will probably eat it alive in a short amount of time. Throttle position isn't the operative factor. I've had cagers tell me they are at 100mph and still have half a pedal left. I ask them if they think that pedal on the floor equals 200 mph? Some of them say yes! ;)WOW! 200 mph stock ford escort.

Right on Robb! That is why these engines have a CDI rev limiter as a stock feature. They red line at about 7800 rpm. They don't do it to be mean, they do it so that the rider will get a couple of years of service from the engine...

Without out it, sure you may gain 5 mph more WOT but you reduce the service life of the engine considerably...

Like everything in life it is risk-benefit
