Norm, theres a FAQ that deals with the picture thing. Basically, you need to upload your picture to a place like Flickr or photobucket. Then right click on the picture, select copy image location, and paste it between the img tags.

Quiet you - all this talk for Flickr techno voodoo bable  ;D .  Sheeees Bubble there you go being practical again.
-Throttle's on the right, so are the brakes.  Good luck.

Cool diagram, but what does it mean?  Should I NOT put a 14t sprocket on my bike?

hell if i know man. i was just helpin the guy post a pic.  ;D


FWIW, i put a 14T on my bike and love it.

Thanks for the help Bubble, I'm not the most computer literate guy around. We're in process of buying a CNC machine so get ready for a LOT more questions!!!
The 14T sprocket gives a different upper chain line & reduces some of your anti-squat (not very much tho). The biggest problem is that it puts the chain so close to the swingarm that you don't have much room to steepen your swingarm angle. Go the the text I posted above & draw some imaginary lines. There is no fixed number that is "the best" - different riders, different bikes, etc. BUT, if you don't try different set ups, you'll never know if your bike is properly set up for you.
Now, if you want to get really confusing, start a thread on chatter. ???

Except the swingarm pivot is not in front of the countershaft sprocket, it's behind it...

I'm not sure if I follow your question nakid, can you elaborate for me?

I'm running 15/43 and the bike is more managable in parking lots & such.  It takes a few MPH off the top speed, but I didn't buy a carbed, air-cooled, no aerodynamic plastic covered bike for top speed.  It works well IMO ~

Yeah, my S4RS has ALWAYS run out of road long before it ran out of power.

what is the point ahead of the countershaft sprocket in your picture?

I think the graphic illustrates the following:

The dot forward of the countershaft sprocket is an imaginary point where the lines of the top of the chain, and from the center of the axle and tangent to the tire meet.

When the swingarm is at the lowest point (squat?) the line of the chain comes closest to the sprocket swingarm pivot.  By going down a tooth (15t to 14t) the chain line (actually, the chain itself) comes closer to the swing arm pivot point.  If it comes too close, the chain can dig into the swingarm.

That's the only thing I can figure out from the diagram (assuming it is dimensionally accurate).

But, has anyone had this problem from installing a 14t sprocket?
