Stage 1 hot cam with new OEM rockers?

Recommended Posts

Hi guys

 

Just wanted to know if i can use new OEM rockers with a new hot cam?

Or is there a aftermarket rocker that is up to it?

 

What do you all think about the stage one cam with the 310cc kit?  Will I have more or less bottom end than the stock 250?

Also What do you think about the xr only header with this combo? If i use the header as well will i lose more bottom end?   

 

I Want to set this bike up for hard enduro so good bottom end is important to me.

 

 

Thanks for your help I am new to rebuilds.

If the XRs Only header i.d. is bigger than stock, then, yes, that usually means a loss of torque over that of stock.

 

You don't say whose cam, so I assume Hotcams. This is a link to the stage 1 for an XR250. It's says it's a midrange to top cam.

The 310cc may offset any low end loss, don't know. Will take someone that has done what you're considering to tell you for sure.
