Does any one know if there are or will be any fuel moduals availible for the CBR 250? Power Commander has "under development" in the CBR 250 category but when I contacted them to see when it may be availible, there response was "probably never".

We have fuel control and quick shift but it is just being put on the website today or tomorrow (cut can be ordered anyway). This PDF will show you all the details and charts. I am installing the Z-Fi QS tonight!

That look's impressive, anyone running yet? Torque down low looks good, was that dyno with pipe or without? Any other details and the shift package could I get more detials? Thanks

I would love a quick shifter on my CBR250R, but it seems more appropriate for a race/track bike. I'll put in pretty low on my list of things to do.

slip on alone

The power gains look pretty similar to what companies have posted for just changing the slip on muffler alone with no fuel manipulation. If their system includes a wideband O2 sensor at a decent price, I might still be interested.

Power bomb

I'll be interested to see how well a Power Bomb style header will work on this bike. The Thai full exhaust system which features an increasing expansion through out the length of the header, is getting bad reviews for poor performance. Guys have been trying these and taking them back off. Exhaust flow resonance tuning becomes less optimal with the larger header pipe?

That was with a slip on.

I installed a FMF full exhaust last week and ran if for a while. I just put on the Z-Fi QS this morning and only got to run it about 3 miles. The difference is certainly noticeable even though I stupidly selected the wrong map.

Now obviously I'm biased, but I'll have before/after charts as soon as the dyno is free. Might be a week or so though.
