Wow...I thought the 1000 would put out much more power...... They are twins though correct? And I doubt you remember me Brian....But we came out from Dayton one weekend long ago when you were first getting into this....Me on my Tribal 600, a Blue Kaw and a GSXR 1000 that you did a bit of tweaking on. You actually gave me a ride op to the Store in your CObra at the time....SO yeah...Its been a while. I need to come back up and re-dyno my bike....LAst time I had it on a Dyno...I got 111WHP out of it....Not too shabby for a 600.
