CDI I Bought Works!

[Cunni]

Well, after searching everywhere, I bought one.....

Revs out to 12000 now and im getting 49 on a flat and 56 downhill (so far)

It now picks up at 9000 revs and so im thinking, is this a bad thing? Will it break my engine if im getting it to 12000 revs a lot?

yes ,at 12,000rpm your stock crank will fail in short order.
 in fact anything over 10,000 is not really recommended
unless you have a racing crank.

How can I lower the revs? It revs from 0 to 9000 off the start now, I got the Dr Pulley Sliders in also and it accelerates quick, just got 58MPH (95 K/PH) Downhill, wondering, how can I get the revs down? Springs etc.?

[harry]

at 58 mph is your scoot  getting unstable ? squirrelly?
changing springs or dr.pulley's isn't going to lower
the rpms your motor makes.
all that stuff is down the line in the power train from the motor.
so for now be easy with the throttle and stay away from  WOT.

usually the speedo is inaccurate on speed on most scooters..
especially at higher speeds, and the higher you go the more
 inaccurate it reads.. at least thats the old cable & dial style.

also your motor will get hotter with more rpms so the plug color
is very important to know your not too lean!!!!
and the heat range of plug is important might be a good idea
to go with a cooler 8 or a 9 ~br8hs  if you have a 70cc  or if stock cylinder
bpr8hs.
                heat kills !!!!!!     

btw; there are adjustable cdi's like this

the blue square has a tiny screw for adjustment.
you could dial it down to 10,500 rpm

remember  when i told you  about changing the gear ratio?
that is really the best way to get more speed from your slightly
moded motor.
a variator with a bigger diameter  would do it too if there is one
for the tgbs

anyway you should ask your mechanic these questions  since your paying
him to do your work ,if he's any good he should know this stuff.
