I have a friend who wants to get a '15 F3 - S which is an SM6. He asked me of you can shift it without using the clutch. I have no idea because I have an SE6. But, both me and that old timer have slip shifted bikes without the clutch for decades. Take it up the the proper RPM and close the throttle, shift up, open the throttle. My CAN-AM shop is closed because of COVID so I can't check it out.
Can slip shifting be done on an SM6?
Yes, and if done CORRECTLY can be done smoothly .... However the SM has a clutch for a REASON .... Annnnnnnnnnnnnd if He / She is planning to shift this way they should also plan on Early Tranny issues. My question is - if they haven't bought the Spyder yet why are they not getting the SE ..????? ... jmho .... Mike :thumbup:Quote:

And VERY GOOD technique... One should lightly preload the shifter in advance and time the upshift perfectly with the throttle blip or it will be jerky... DO NOT DOWNSHIFT using this technique!Quote:

" so not true " .... please explain to me the difference between " properly " and " correctly " and as to the " black lettering " .... I have met some people who can't shift ... USING THE CLUTCH .... so I'm not about to assume " everyone " can shift PROPERLY without the clutch .... jmho .... Mike :thumbup:Quote:

No doubt it can be done, and will find the next gear. Will it damage or harm the gearbox, likely no, but it will cause increased wear and rounding of the gearbox drive dogs.
To reduce wear and add longevity, it is best to at a minimum unload the gearbox with even a partial pull of the clutch.
As a kid racing dirtbikes in the 1970s, it was common to upshift, even downshift without using the clutch. When you open a gearbox up and see the rounded dogs, which requires replacement of the worn gears, it is disturbing.
Since the 1970s I prefer to use the clutch whenever possible. Not pulling the lever fully to the grip, simply enough to unload the gearbox. Learning this way of shifting found it is faster to not back off the throttle to shift without the clutch, but rather to leave the throttle pinned and allow the rev limiter to control rpm, while you partially pull the clutch and take a gear. On the larger displacement bikes, the rev limiter came into effect less, since the same technique was done at partial throttle settings.
As for a Spyder, since it is accepted that the gearbox is the same for the SE and SM, and the SE electronically cuts engines power to shift gears, the question becomes, does the SE also cycle the clutch during shifts?
Thread is moot. He ended up with an SE6, same miles, same price, same year, same color. I never get that lucky. Added bonus, windshield, buncha lights.
Good Quality Tranny Syncro helps: :bowdown:
