Merci Emmanuel (Guyem) pour ta contribution !
Excellent links and information on your ignition and tuning !
Besides Guy on track footage, this U Tube link is an absolute "caviar" for the ears :

As far as Dynamohum pertinent question, correct me if I'm wrong, but I don't think you meant to write that the engine
was stock because obviously it is not after changing :
<< ignition , exhaust , suzuki bandit carbs , oil pressure , oil cooler , compression ratio , AAC (THESE MEANS CAMSHAFTS) >>
Did you mean to say that the stock displacement was left at the same bore ( CC ) but with higher compression pistons ?
The increase in power and RPM band is not surprising in view of what was done to this 1045 cc engine !
- I agree with many of your remarks in your web page, when you mention how sensitive ignition tuning is on the CBX, I know because I have experienced it too with my mechanic friend, and had to re-set completely after installation of a Dyna S module, and the timing was way off before.
- However, I don't know why keeping the stock coils which are NOT good and most often cracked with age... there are better options on the market now.
- You are also correct in pointing out how sensitive the 6 is with oil temp. ! It affects greatly the performance of the engine.
- As for the rest, it is a "no brainer" when you swap for better & bigger carbs tuned with the right exhaust...
As for the Brancquart bike, I had a chance to discuss it with Lionel Brancquart himself and his friends at the SRC a few weeks ago, and while it sounds farfetched to see a CBX engine reving between 18 & 20,000 rpm, I got to say that this engine only has the look and engine cases of a standard CBX... there are so many mods that it defies imagination ! Lionel and his Dad built this bike more as a challenge to push the envelope as far as possible... and they did ! I saw the bike up close and it is a master piece !
Great work !
