F800GS 15 Tooth CS Impressions & Questions - Page 4

DidYouSeeThat · 10-12-2009, 11:05 PM

I just ordered the 15T. I am looking forward to slowing down on the technical stuff (everything is technical for me

)

Dang, I hand is tire from pulling in the clutch. I have stalled because the 1st gear is just too tall. OK cry cry cry... ;)

Of course, I'm used to a KLX250 that has a granny first gear - that I Love.
I'm not a top speed guy anyways, I love the 10-30mph stuff off road.

I'll report back when the 15T is on!

If interested pm me with your email address and I will send it to you.

Here is a screen print -

If you want to send it over to me, I'll post it up on F800Riders.org for all to download.

Bushwackers's gearing worksheet is now available here:

No download, no excel required.

(sorry Wildman - momentary brainfart!)

Nothing to do with me.

From the factory the clutch friction point is WAY out there. I've adjusted the clutch cable (at the engine case) and have found moving the clutch engagement point closer to the grip has made low speed handling easier and given my left hand a break.

Hmmm Good to know. I'll try that.
Thanks

Seems that would just put more slack in the cable. No?

that is indeed what you are doing BUT by doing so you increase the amount the spring-loaded clutch cam needs to turn to engage. The cam is spring-loaded and takes up all the slack created. Hence, you move the friction point closer to the grip by increasing the amount the clutch lever needs to be pulled in to reach the friction point. For someone who uses two fingers on the clutch and brake, this made life much easier and made slow speed control easier.

As usual, YMMV.

Ah. On previous bike's I've owned you could only let out so much slack. I'll have to check that out.

I just did mine and took it for a ride it does work. The clutch is a firmer pull on the lever.

It would seem that at some point adding more slack would reduce the actual throw enough that the clutch would not completely disengage when the lever was pulled all the way making the tranny hard to shift ... is anybody seeing that problem?

Certainly a possible complication. A gradual adjustment should yield the desired results. There's a wide range of adjustment possible.

I stalled the 15T
Ohhhh I rode the BMW with the 15T. Wow, it is smoother… I don’t understand why, but this is how it should have come stock, this is nice.

I thought it would make it jerkier. The power comes on strong but more evenly. Snappy throttle is solved!

Anybody know why this works. Is there such thing as too big a gear on the front and that causes the snappy-ness...

I’d love to hear a physics type explanation if any body has that training.
Thanks

15T... I love it!

Where is everyone getting their 15t sprockets?
