Results of 13 tooth countershaft sprocket?

Has anyone changed the front to a 13 and left the rear stock? What was the net result?

I find myself between 1st & 2nd in the twight twisty rocky stuff and would prefer to remain in 2nd. Any Feedback (other than learning to ride faster)?



I run a 13/50 combination last summer and it worked well in the tight Michigan woods. 3rd gear is a blast ----

13/50 is what I ran on the xr6 and same on my kdx250

Seems to be a great gearing to pull 2nd all day long in

I found myself between 2nd/3rd too often on various desert trails, so I switched to 13/48 a and I really like it.

Thanks for everyone's input!

I'll be tying a 13 tooth this weekend...



I had the exact same problem- too much time in 1st gear in the slow stuff. I went to a 13T front sprocket with the stock 48 rear and solved the problem. Best part is that a front was $15, instead of paying $50+ for a new rear sprocket.

I have a XR650R with power up and I right tight north MI. trails I had a 14/50 loved it good power out of turns in 2nd then went to a 13/48 ok but I liked the 14/50 better doesnt seem to lug as well out of turns if i were to do it again I would do a 14/51.

I use a 13/50... it was the only way to get into second in the woods. So far, so good, no chain stretch or huge wear issues (but then I don't ride nearly enough!). If I pin the throttle in first gear on the pavement, I CAN'T keep the front wheel down. What a hoot!

Well gang, I rode with the 13 on Sunday and loved it in the tight stuff! I was able to run 3rd most of time and only dropped into 2nd in the real nasty areas. 3rd is a blast!

Thanks for everyone's feedback.

      Changing out my fork oil on a new to me 650l. What's generally recommended for stock springs and valving?

      So I don't seem to find my specific issue so here I am asking. 
      I have a 1997 Xr600r. It was recently re-jetted and has ran really well ever since until more recently it has begun to have this issue.
      Everything works fine. Kicks right away, nice and easy. Runs great, sounds great, purs. But when I'm downshifting and slowing down to a stop, if I let my hand off the throttle that's when it just dies. I found that I can counter this by lightly holding the throttle as I down shift (so I'm revving quite a bit during downshift).  But it hadn't done this before. 
      The only thing I've done that I suspect may have been an issue on my part was when I pulled out the engine to change the valve cover gasket and upon doing so perhaps when connecting the carb back to it, I may have missed something or made a crack in the boot? 
      Any ideas? Thanks

      Hello all,
      There's been a lot of talk about how to register a dirt bike in states that don't allow it.
      I just moved to North Carolina and for the first time in my life might be able to afford a bike. I've been dreaming about an XR650R for a long time, but they're not cheap. Plated bikes seem to be more expensive too. So here's my question, has anyone tried to plate a dirt bike by adding all the necessary features and having it inspected as a custom bike? Anyone know of another way I can plate an xr650 in NC?

      Hoping for some help before I throw in the towel and end it all!
      Engine starts fine, runs and idles well for +/- 10 minutes, but cuts out while riding once the engine warms up (175 - 185) and intermittently cuts out thereafter (any speed/gear). It will start up after 30 seconds or so (but won't run for long before dying again). No spurting or surging.. just dies.
      I've replaced CDI (twice), Spark plug, spark wire and coil, and most recently pulse generator. I do have a 41mm Flat side carb from a CRF (and it has more power than the old carb setup), breathing through a Uni filter. Also, sealed battery tender battery (hasn't shown low when trickle charged).
      What's next on the test/replace list? Stator maybe? Please help...
