I know this has been brought up before, but I couldn't find the post. Does it harm the transmission or engine if you back off the throttle while upshifting ? I find it is smoother than just letting the SE5 do the upshifting without letting go of the throttle.

I want to thank everyone for the feedback on the throttle.

If you get to the proper RPM's, the bike will shift effortlessly, quiet, and you will not even notice it. The rolling the throttle is for SM5 or SM6.
The 998/2 likes to be shifted at 5000-5500 rpm's. Seems high to some, but that is where the bike starts waking up. I never used 5th gear on the 998's until I was at highway speeds over 60.
The 1330/3 likes to be shifted at 3000-3500 rpm's.
Does it harm the engine or transmission if you do back off the throttle when upshifting ?
Thank you for your response.
I " Drag raced " ( at race track ) a V-twin and my 1330 ...... power shifted all the while ( got a :firstplace: an a 2nd. place trophy's ) . I can't think of a reason why letting off the throttle would/could hurt anything ..... good luck .... Mike :thumbup:Quote:

Spyder f3s (tuned for bit more torque, in the low revs) I love to ride/ cruise round 70/80 km's per hour, and after tuning, I run at 2200 rpm, and not lugging the machine, have to say tho, I use premium gas, and overhere ( the Netherlands)premium isreadily available,and of consistent quality, and no ethanol derivates in it.
I've not owned a V-twin but when you ask if it will harm the transmission I doubt it, but remember, the centrifugal clutch requires the higher revs to fully lock up so why back off on the throttle and then have to spin it back up to fully lock the clutch.
thank you for the feedback.

But that's only valid for the 1330 3cyl motored Spyders Piratezz; the OP here, Motogordo, has a 998 V-Twin that's a high revving motor with a centrifugal clutch between it & the 5 speed gearbox, and shifting IT at anything less than about 3500 rpm WILL harm the centrifugal clutch - unlike the oil/hydraulic clutches on the SE6's that back the 1330's, the SE5's on the V-Twins NEED to be spinning at least that fast for the clutch to fully engage!! :lecturef_smilie:Quote:

My bad, didn't notice that he was talking bout a 998V-twin, I have no experience with that engine. Sorry for misinformation, was only trying to help.:2thumbs:
No harm, no foul Piratezz; it's all good info that's been put out there, and if it happens to help a few people along the way, so much the betterer! :ohyea:
I was just posting the evxtra info to make the differences between the different motor's 'preferred rev ranges' & the different clutch requirements clear. :yes:
Thanks for the info in this post. New to Spyder and coming from a 2 wheel motorcycle. The 2013 manual only talks about 3200 +/- 200 for shifting and the dealer says shift at 4k and many say shift at 5k or better. Seems like it’s learn the speed at which shifting keeps the next gear at or above 3500rpm will be the target.
The manual is telling you when the clutch is fully hooked up. Those of us who have been riding the VTwin awhile like to shift at higher sppeds . Some like the lazier life at 4000, some like to let the 998 wake up a little more and shift at 5000/5500. I shift mine at 6000 and cruise at 5000. That translates to about 70 mph on my spyder, which is just right for me. As long as you stay above 3200 so your clutch stays hooked up you can do what u like. As far as rolling off the throttle to shift ,no it won't hurt any thing but it may confuse your computer as to what you are doing as the recommended way to shift the SE5/SE6 is to not roll the throttle back but to just shift.
