high winds and coasting issue

[bobm_dr350se]

<<>> Hi guys, it's just math. If you change from a 15T to a 16T, at the same RPM your speed will be 16/15 more. i.e. 59 X 16 / 15 = 62.93mph. Bob DR350 A15

[Fred Hink]

All the years I have been on this list I don't recall anyone posting a 10mph increase when going to the 16T sprocket. I do remember posts indicating about a 300-400 rpm drop at highway speeds when going up one tooth on the front sprocket. Maybe you had your hopes set too high? Fred www.arrowheadmotorsports.com

Hi Fred,- Interesting subject. I have a friend who owned a TW-200. The bike had a top speed of 65 with him on it. It was always a problem to go anywhere on the super highways. He could just keep up with the slowest traffic. Whenever I passed a car he could. We decided to go with a smaller rear sprocket. We went down 3 teeth. The result produced a top speed of 80 mph. But not consistently. If head wind was strong he would go down to 65 mph at times. The only way he could do a steady 70 - 75 mph was to position himself behind me or off to the side on crosswinds. He ended up selling the bike and bought a used DR 650.

I went the other way, to a 14t which helps off-roading tremendously, and makes it harder for me to get speeding tickets on the highway. The motor redlines at 97mph indicated. My $.02 on the 16t dilemma is no two of the stock speedos ever read exactly the same. Unless you're using a GPS or a stopwatch and mile markers, 2 or 3 mph differences with different bikes is below the % of error. Devon A15 Fred Hink wrote:

Someone on the list a few years ago wwas running a 16/40 setup on the klr and was pleased with the gas milage and RPM drop, I dont remember who it was. Mike

With so many people evidently disapointed in the 15 to 16tooth conversion (I haven't done it yet) it simply leaves me wondering if Fred can acquire a 17tooth since that should give almost exactly the 10mph drop. So what about it Fred? Anyone make such an animal for the KLR?

[Fred Hink]

I have been told and don't know from first hand knowledge that a 17T won't fit first and if it did the KLR wouldn't have enough "beans" to pull it. I can get you a 17T but comes without any guaranties. Fred www.arrowheadmotorsports.com

The problem is it won't fit, the 16t os very tight. John

Mike- There is not the clearance for a 17T sprocket... It would shred the stator wires. If you could reroute the stator wires and remove the section of the sprocket cover which shields them, then you might have enough room, but then you run the risk of the chain eating through your engine case. A 16T sprocket is dangerously close enough to doing this already, a 17T would definitely cause serious problems. If anything, I would go down in the back and down in the front, so that a 14T/4? would provide the same gearing as a stock 15T/45, a 15T/4? a 16T/45 and a 16T/4? a 17T/45... A 13T could be used to provide the same gearing as a stock 14T. I think the rear is 45T stock? Perhaps a 39T would do this? I'd have to sit down and calculate the ratios, but if I wanted better highway gearing this what I would look at. Your first gear would suck, but I find with the 16T it is easier to pop wheelies than with the 13T, it has me mystified. Z

That makes sense. I'm pretty happy with the range I'm pulling now though a hair less rpm at 70 would be good. Before I worry about playing with front sprockets I need that front fork brace, lowering link, and a non-tweeting exhaust! (probably the Laser) Somewhere in there would also fall the progressive front springs. If the 17T won't fit any chance that a 16T with a few less teeth on the rear (say 2?) make up the difference? Still seems that it would take a good bit of torque to move it.
