Wait, i gave you the Valve sizes for the CRF50 heads. The 110 TB valves are 28/23 and the +R valves are 28.5/23.5 but its still a better head ask anyone that ran both.

i think the difference is in the CAM you can run with the +R head. Ports might be a little different but 4 strokes are all about the cam.

The difference is in the CAM.... The +R is the fastest out right now... But the TB head is the best bang for the buck

The roller rockers have less friction, yes, but it's the rollers that allow the cam profiles to be much steeper and open the valves much faster.....

I have had both the TB and the +R heads.....the +R is BY FAR AND AWAY BETTER, IMO. It revs super quick, but with my heavy piston and stroker crank it doesn't pull for too long. But I really like the +R.




thanks man i needed some first hand experiance info on both of these
