Power Shift

[fvincent]

Ill ask one more time. Is it possible folllowing all the recommendations on our site regurading transmission repair / fixes, to make the transmission on the XS1100G, reliable enough to powershift? New gears, Dremel, move the washer and additional washer, (Bob jones). Has it been done, and can you powershift?

Sure

A lot of ppl here shift without the clutch ,If thats what you mean, But you need to know your bike and understand what your doing. I never use the clutch on a truck once i get going but you can do some damage if your not on your game. You can bend shifting forks ,wear out sycs,damage teeth etc. so why it a big deal to use the clutch? Not being a smart ass just wondering .

Hey Floyd,

IF you mean shifting WITHOUT letting off of the throttle, not a good idea! Speed shifting without the clutch can be done as has been stated, but takes some deft timing with the throttle to be able to blip it just right to take the load off of the tranny to allow a quick shift before getting back into the throttle. It actually shifts fairly easily and quickly when in the upper rpms like that, but again helpful to reduce wear to dogs/slots by letting off of the throttle just split second to allow the shift, and then back to WOT if that's what you are wanting to do.

I did some power shifting for the few short runs I did a couple of years ago when I was running the 1/4 mile at the track, but other than that, I prefer the clutch!

I would not shift without letting off the throttle, but to repeat the obvious, I usually shift without the clutch. Its simple. Just put a pressure upwards on the shifter and let off the throttle like you normally would and the shifter will move automatically at the perfect time.

Shifting without the clutch is all about loading and unloading the trany. As pointed out if your smooth and FAST you can throw it up to the nest gear at the exact moment that you unload the trany. Down shifting is trickier but can also be done. I use my clutch but do so, so quickly it's hardly worth it to bother "power" shifting.

clutch?

I almost never use the clutch when shifting up and almost always when shifting down except when needing more power quick. Like hobbyman said, it's quick and nearly automatic. Racers use a device that cuts the ignition for the shifting sequence, saves dropping the throttle to do it.

If your question is, can you powershift this transmission with the idea of putting an air shifter on it? I would say no because the XS transmission is not truly automatic.

Its kind of like dancing. You have to use your mind to make both feet work in harmony. For a good clutchless upshift on an XS you need to just 'wrist' the throttle for a heartbeat to unload the drivetrain. Now comes the tricky part....while unloaded you have to shift FIRMLY into the next gear.

I have upshifted for many years without the clutch and have never had to touch my tranny. But, I dont do that all the time....I do use the clutch most of the time. IMHO, if you want to shift with a button then I think you would need to have an electric shifter or an air over electric shifter to do this.

Thanks People

I had a Kawasaki Mach1 3 CYL 2 stroke back in the mid 70s'. could dump the clutch, and shift through the next four gears full throttle by just blipping the clutch when shifting. Never ground a gear. If I remember correctly, 0-60 was around 3.6 seconds. The only stock, (and emphasize stock) vehicle that could beat me at the strip was a Bombardier TNT 900 running in the grass. Nice completely black bike. I needed the money and sold it. New owner reduced it to a ball of junk. Actually flipped it over backwards. Thanks for the input!
