Apparently WhiteBrothers make a replacement "Rev-Box" CDI unit for the little CRF, where can I get from?

Und so I take it the results are less than spectacular if we are not hearing about it?

#Power Up Needle
#132 Main Jet
#45 Pilot Jet

Honda part nommers:

16012-KPS-921 “ Needle (Includes Power up needle, Clip, and needle jet)
99113-GHB-1320 “ Main jet (Where 132 is the jet size)
99103-MT2-0450 “ Pilot jet (Where 45 is the pilot jet size)



Snafu how does bike run with the 132 main jet?
There seems to be some controversy on the net about which main jet to use.
Some people say use a 120 others say use a 132.

So I would very much like to hear your impressions.

The 132 is part of the Honda power up kit.
Like previously mentioned, i was not running the kit, but have ridden one with the 132, but unfortunately, cannot compare to 120.

Thanks for the link.

Here is what I picked up...
Quote
Tried a 45 pilot first and was still too lean (Popping on decel)
Tried a 132 main first and was too rich on top (Flattened out)

I am now using Mike Coe's dyno jetting recommendations and it is worlds better and as fast as my buddy's XR250! For those of you still running a 132 main, you're missing out on 1.8 HP, and that's about an 11% gain. Here is an excerpt from Mike's dyno work"

"It was worth more than 1.5 HP!! With the 132 the A/F mixture was @ 11.0:1 and the power would level out at 16HP. After going down to a 125 and then the 120, the engine pulled cleanly all the way to the rev limiter and 17.83HP. This was on a bone stock 230 with "power-up" mods. I could have gone even leaner and picked up a little more power, but decided to stay a little conservative."

So the suggestion seems to be a 120 main jet...

What exactly came with your power up kit?

I have also managed to find the following which is very interesting and should help others out there..

Quote
If any of you have any doubts about Mike Coe’s dyno work I suggest you line up against someone running his jetting recommendations and be prepared for a wicked beating. My 230 is now like a whole new bike and I am no longer being left behind the XR250s!
 
Spend the money and the time and go do it!
 
Final results: 48 pilot with 120 main and 03-05 needle at #4 at sea level. See the chart below for variations on Mike's jetting:
