cafe racer fan.. ive got more in store.. bluetooth connectivity from the ecu to tablet, for autotuning fuel values while driving to get a baseline before the dyno.   also will do logging to my phone, and tuning from my phone if needed. :D

Fantastic. I need that on my dfi bike :)

Watch out with non-braked dynojet dynos.
I could run 1 bar boost on the dyno with stock timing and compression while on the road it pinged at 0.6 bar. 🙈

updated in the project forum. but might as well add the video here too :) 

Had the bike at Oslo Motorshow recently and won the "Best engineering" award :)


Also.. the bike fired up first attempt, and actually runs (even if it is not tuned properly yet).

IT WORKS!

The fabrication of the fuel injection system and supercharger are so impressive.  We are all cheering you on to get the bike tuned to see what it can do!

I'd say so. I think it still belongs to RC, Jr. and RCE.

I'm extremely impressed with this bike. Fuel injection builds always intrigue me and to add the supercharger really took this bike to a whole new level in my opinion. Thanks for sharing all the details along the way. While I don't think i'll ever try the supercharger aspect, I'm very interested in one day attempting the fuel injection conversion on one of my drag bikes. Your build is clean, nicely engineered and not cluttered. I can see how it would easily win an award and would be my first choice as well. Congratulations.

thanks
