The results were pretty much as i expected. As detailed in my page on the CBR, I changed out my chain and sprocket sets to a 15/44 and a 520 chain. From a 16/42. So essentially I have substantially changed the gearing. lowering my top speed and top end power and adding brutal off the corner acceleration. My primary goal was to set it up for a gearing that would be most useful in track conditions, and lets face it, a trip to Izu is just a slower version of a trip to Motegi!
I really like the changes I have made. I lengthened the axle to swing arm length by about 1.7cm. Which will had the effect of changing the way the rear shock responds under load. A change in length will effectively jack the rear of the bike up a little. As a result I upped the rear preload by two notches on the stock showa unit. I would like to spend a bit of time adjusting that a little more once I get some new tyres on. I could do with a little more rebound damping to slow the shock down a little, It may reduce the “flickability” a little in fast transition corners but it means that when it gets there it will be more settled.
Anyway I really liked the results all over the bike. The front was nice and planted and the drive off the corners was phenomenal.
Very happy!!
