Hello, if one wanted to reduce their sprocket ratio (less torque/more top end), it can be done in two ways, one way is increase the tooth count on the front sprocket, and the other way is to reduce the tooth count on the rear sprocket. Is there any benefit in one method over the other if either change works out to be the same ratio? Thanks, Dennis...

Making the front sprocket larger will bend the chain around the sprocket less and should make the chain and/or sprockets last longer.  You also should be able to use the stock length chain by just changing the front sprocket.  If you change the rear sprocket more than a tooth or maybe two, you will have to adjust the chain length.  It all depends on how worn your chain and sprockets are.  It is also somewhat easier to change the front sprocket than the rear sprocket.  Fred www.arrowheadmotorsports.com     [b]From:[/b] bufbooth@...

Many of us like the 16T front sprocket for that purpose; reducing the revs a little on the fwy but still having enough torque for all but the most radical hill climbs. 16T works with the stock length chain. To get the same effect on the rear, you would go from 43T to 40T. It is less work esp. steps to change front sprocket although it is often hard to get the countershaft sprocket nut off. Jeffrey #3

#ygrps-yiv-569343503 p {margin:0;}I flip back and forth between 15 and 16 depending on what I'm doing.  The prevailing torque nut is a tremendous help if you do it frequently.  So is an impact wrench if you don't remove the nut all the time.  I can change mine with a standard ratchet in just a few minutes' time.  I put a little anti-seize on the splines and threads of the countershaft to make the changes go more smoothly.  I also have a puller I picked up for 15 bucks at Pep Boys that makes it a snap to remove sprokets that are stuck on the shaft.  I do a little shadetree wrenching for other people to increase my farkle budget and I got tired of fighting with sprockets and bought the proper tool.  It's amazing how much easier things become when you have good tools. It's also amazing how much easier it is to do things if you do your maintenance yourself, and do it frequently.  For instance, my messenger buddy with the KLR needed a set of tires installed.  Since I do my own maintenance on a regular basis it takes me no longer than 2 minutes to remove my front wheel.  Doing his, however, took 3 people the better part of an hour just to get the wheel off.  The crappy shop he had taken it to had installed the very soft pinch bolts to a torque that The Incredible Hulk would have been proud of.  Due to the particular alloys, lack of lube and the ridiculous torque the bolts were gaulled in place.  After much ado, we sent him on my bike to the store to get some nice high-grade bolts while we heated, drilled and hammered his old ones free.  After a touch of anti-seize and proper torquing, hopefully he won't have any more problems with that. -Jeff Khoury

Making the front sprocket bigger (at some point) WILL give clearance problems. Cheers, Ed

#ygrps-yiv-1830495027 p {margin:0;}Based upon experience, 16T will fit without modification, but will leave a rub mark on the cover. Based upon my research, 17T requires a little clearancing of the plastic cover.  14 and 13 fit fine, but some complain of excess wear on the chain with the 13.  Can't vouch for the "truthiness" of that though. Going up on the rear sprocket may require going to a 108-link chain according to my reading (Stock is 106). -Jeff Khoury

Running 14/45 with 106 chain perfectly.

I'm currently running Shinko E-705 TRAIL MASTER DS tires. Inexpensive and work fine for me (handle ACE on road!!!). Ed
