Can I run a 16T countershaft w/ an XRs Only sprocket cover?

Recommended Posts

Correct me if I"m wrong but stock 2002 XR650R front sprocket is a 15th? that's what I have now. I'm wondering if I can run 1 tooth larger (16 tooth) than stock up front with the XRs Only sprocket cover?

I thought I heard somewhere that this aftermarket countershaft sprocket cover had some clearance issues? Or was it the case saver? Anyone set me straight?

You don't even say what kind of bike you own.

Here's what my post says: "Correct me if I"m wrong but stock 2002 XR650R front sprocket is a 15th? that's what I have now. I'm wondering if I can run 1 tooth larger (16 tooth) than stock up front with the XRs Only sprocket cover? "

A 15 will fit. I don't think a 16 will though. If I remember right, you are talking about the "case saver" made by XR's only. I had the same case saver on mine and a 15 fit fine.

One thing I will give you fair warning about, If you put a 15 on that bike, hang on tight! It will peel your eyeballs back in your head and your bike will do close to 105mph.

I am running a 16t right now but with the stock cover and saver. I did take the belt sander to the saver for it to fit, so I would say no. but I think they sell one for the 16t at xrsonly or have in the past.

What would be the reason to run a 16t? The bike does almost 100mph with the stock gearing.

It will not even hit the rev limiter with a 15t on the dry lake.

OOPS! My bad. I see your bike is a motard...

Where do you guys get a 16t for the R? I've searched and couldn't find one.

Me too. I have been told that there is no such thing as a 16 for the front. Strange.....

Hmmmmm.........I run 15/40 gearing on my street motarded XR-R.....if a 16 tooth will fit, this could get interesting.

I switch from dirt to motard but I want to use the same chain, so a 16t is an easy way to get a little more top end.

A little more top end? With a big bore kit, high compression piston, cam, and a little headwork, you will have the E ticket ride.:moon:
