ruttly  I haven't smoked in years ,didn't you ever see the ratios normally used for chain conversions? 17/45 ,17/47 , 17/43etc. all having numbers not being able to be divided by 2 . Maybe you should read more and ride less ,and not pay good money for a custom 54 tooth gear.check out JOG's link above ,and you'll begin to understand the error of your ways!If your running an18 front your running ,I'm guessing ,plain chain ?If you go with the 17 you have room to run an o-ring chain that might not snap and hit you in the a$$.FB chain.com,"a sprocket with odd numbers of teeth will offer at least double the service life of a sprocket with an even number of teeth"-Peter Church-FB chain

Oh just havin some fun , thanks for the link , I will read it !

It is true.....you should avoid ratios that will run the same tooth on the same chain link repeatedly.  Porsche even has their boxer engine set up with a missing tooth in the primary cam gears and an extra one in the cam chain sprockets so that the gears and chain pulleys are always moving around to mesh with different teeth and links.....it evens out the wear.

automotive gearboxes have odd numbered gears for the same reason.

Ouch, justin. As someone who works in an academic library, I object. That attitude just makes it harder for me to earn a living. (just funnin' ya. The interwebs is awesome. Lots of chaff to sort through though).

Anyway, doesn't Yoshi have a chain conversion for sale? Why don't you buy that, cheapy? Be less than a new set. Oh and count me out for the custom 5th gear. My Cabbage only has 4. And it's just right.

I hear ya  

Ruttly,It keeps me dry in the rain! If you go to a 17 tooth you might look in to a geared idler bolted or welded to your swing arm might help with your clearance problem.or shorter/longer shock spring lengths depending on your tire to fender clearance.

Kris,fits just fine 18/52 is what RYCA says is closest to stock gearing.

Batman,With the 54 in rear gave me the clearance needed,17 won't change clearance that much. Was out riding it today noticed that rear shocks have 0 sag,springs to heavy,causes push when going into turns too fast,forks feel real good. Already had to fab chain tensioner due to swingarm angle caused by longer shocks. Lighter springs & 17 are next. Shawn's upgraded front brake is seating in & is bad ass what a great binder with great feel !

RUttly ,sounds like your taking care of business! I"d watch that rear sprocket being alum. it may wear a little faster than the front ,good luck ,ride safe .
