06 Daytona cams in 15 Street Triple - valve clearances?

Hello everyone! I am planning to install some 06 Daytona cams in my 15 ST, and have a question. In my Haynes Manual, the valve clearance on the exhaust cam for the earlier Daytona is 0.275mm to 0.325mm, but for my ST it's listed as 0.325 to 0.375mm. When I fit the cams, should I use the clearances for the Daytona, or for my bike?

Thank you!

The cam journal size is different between gen1 and future gen engines.


06 cam journal size 23.900mm
09+ cam journal size 23.950mm with a minimum size of 23.940mm


It might work, but it violates the service manual's specs.

Hi there, thanks for your response. I didn't actually see this in time, and I have now actually installed these in my bike. They were indeed 0.04MM smaller in journal size than the cams I removed.


The bike runs fine, aside from fueling issues. I hope the journal size difference will be OK.

Thanks again!
