I will go with Webcam 70-681 with duration @ 0.050" :In: 256 ex:236 and valve lift: in: 0.400" ex: 0.340". 38 degrees overlap.what cams did you go with?
Actually I didn't. But the parts which were worn was: 5/6th gear on the countershaft and it's shiftfork, camchaintensioner-guide. Other than that, it was fine. I've replaced the crank and rod bearings as the crank has been at APE and have been lightened and balanced. They polished the crank journals a little bit.Did you measure it up for wear. I am interested to know how worn it was against the service manual specs.
Sorry for not updating enough. Have a ton to do at work, and a girlfriend (not the gixxer :biggrin) who needs her attention too.Any updates with the build Emil?
Thanks, no they are probably 20 year older than me. I'm 22 .Real nice work and good workshop. Did you make the engine stand?
Thank you! Yeah, maybe I'm, I felt it's was time for an updateAwesome Emil! You must be a mind reader bcuz I was just going to Emil you today to check on your progress. The Akrapovic will definitely help you free up some hp. Also, since your thinking of increasing the rev limiter, turn the rev limiter up to 13K.
12.8:1 AFR seems a little rich. Try leaning that out a bit and you will see the hp go up. Tune to the most hp, not sum magical AFR number that everybody seems to believe exist. GSXR's run better a little learner up top.
Good luck man!
