This morning leaving from my mountain get-a-way on Angeles Crest Hwy I went past Newcombs Ranch and several miles down toward L.A. I caught up to and rode(er, pushed) an H2SE for several miles!!!!!!!! He turned right off Hwy 2 and I wanted to stop but I had to be somewhere else. He had the side bags on and also had the green stripes that you are waiting on.

Possibly the best $250 performance mod ever. ECU flash on 100% stock H2SX. Cool

Impressive to say the least. At a fairly sedate ( I assume sedate with this engine ) 11k rpm, that is a major boost even if you discount the top end increase. True seat of the pants improvement.  

Bring it to the Borscht Burn, I would enjoy wiping it down for you while you have a beer!  Wink

I was at my local dealer yesterday shopping a new ride and they had one of those Hyper st beauties on the floor. I really liked it, surprisingly comfy ergos even for my decrepit old a$$. I had to walk away before I bought it. Lol

No mortal can use any of these bikes to near their capabilities. I haven't done this ECU flash, but I might this winter. Lol

I’d need to know more about mileage impact before the flash. That could be a balancing act. Can you toggle between each map?  I doubt it ... That would be an ideal setup!  

Haven’t seen one yet.

Well, based on the dyno above (when in Full power mode) it will only drink a lot more gas on the top end. But the flash has a touring mode which is supposed to give the same or better mileage as stock ECU.

Riding normally, and only going crazy once in awhile, I currently get 40-42 mpg. The bike is tuned to give very good mileage when ridden tamely, cruising, etc. But gets very thirsty when ridden hard and the supercharger is drinking air like crazy and fuel injection is working hard to keep up.

I wonder why Kawi used a Supercharger instead of a Turbo for the H2 ?

Could be that you are correct.  

I guess you have to pick your poison.   A supercharger uses up some HP.

Turbo lag. There's no lag (or almost nil). The SC is driven off the crank, via gear and chain, then final planetary gear. The system steps up the crank RPM something like 9.1x, so at redline the supercharger impeller is rotating at ~120,000 RPM and pressuring a the airbox, which is made from aluminum and bolted to the throttle bodies, and has a blowoff valve.

The engineering is kind of amazing, since it all mostly fits in the same space as a normal 1000cc engine. The SC has no special maintenance either. You do one inspection every 7600 miles, that's it.

 Lol Don't even think about it. So smooth and quiet to be honest. Not as unruly as a regular H2.

I finally got my matching color panels that were backordered for almost 2 months. So why not a couple more pictures. Lol

Considering the Yoshimura Alpha slipon...mellow and not ridiculously loud. Shaves 8 lbs. This bike does not need a full system,  Crazy that money is better spent on an ECU re-flash if one is looking for bang for the buck performance.

It's certainly smaller and better looking than the stock pipe.  I'll never understand all the odd angles and extra layers on new Asian stock exhausts.

I'm still waiting on my green panels.  But, I've been enjoying riding so far.  I too am curious to experience the ECU flash.  Just because Smile
