MC tranny question

slipper clutches are used in racing. they do allow some off throttle slipping, but not complete freewheeling. i believe they are used smooth out high rpm downshifts so they rear tire doesn't break loose.

High IQ already knew that. He was just testing you. ;p

I cut and pasted this from my gs250 manual, the real trick is figuring out where to put the other neutral detent(s) slots on the drum.

I would suggest finding the mid point of the neutral you want to add (i.e. between top gear and top gear -1) by:
1. put it in neutral on center stand.
2. remove detent spring thingie, take a look in the hole while you are there.
3. locate the neutral you want to add by hand. Split the difference between the two gears where the dogs just touch (spinning the rear wheel might help), gently lift or push down on the shifter to adjust. Use the detent hole to help get your bearings.
4. put a dab of prussian blue or something on the tip of the detent ball tip and install it to mark where the new slot should go. Then remove it, all without disturbing the shifter drum. Mark the location more permanently with a sharpie or scribe or something. Hopefully this leaves a clean mark, might need to try something else if not.
5. cut a slot with similiar dimensions to the existing neutral slot at the new location.

5 is easier said than done If you can devise a way to do it through the hole (if your bike has a hole) then cool, otherwise it is disassembly.

did a little reading on slipper clutches and found they are adjustable, so perhaps they can be into actual freewheels.

^LOLZ!

Without fail, those who feel the need to point out how smart they think they are, aren't.

So, just to be clear, one would need to cut a grove similar to the one indicated by the circled 2 in the lower left hand picture between 5th and 6th gears? I can't ell by the picture, but I am assuming there is a slight grove between each gear, and it would just need to be deepened and widened?

Thanks,

Yes, that #2 is a groove across the drum that holds the whole drum at that location for neutral via the detent ball/spring. It is a big enough groove that you can feel it with your toe through your shoe, but not so big that the drum can wander around. And if there were a properly located groove between 5th and 6th then it should probably work as a neutral up there as well.

I'm not sure if the other gears have detents, maybe. If you get a look in the hole and shift through the gears you will know.

I deleted the content of one of the posts in this thread.

Guys, if you can't play nice, just put each other on your "ignore" lists.

thanks
