F3 Top end power loss

[kenfromhv]

Deleted - Bike working OK

Forgot the 1330 is low end torque, and I never had it above 4000 rpm's with the vibration issue. Now fixed I go over 4000 rpm in mid gears.

The old 990 high end torque only kicked in over 4500 rpm.

Big difference that I forgot about - sorry.

I've nto experienced this, but the issue raises a few questions.

Did it start after the idler was fitted and have you tried removing it and seeing if it stops?

Also on the new rear rim and tyre, is it an OEM tyre or other replacement? May have changed the gearing if it's a bigger size.

Could belt tension have something to do with it?

Is ECO Mode accidently turned on? :thumbup:

Is ECO Mode accidently turned on? :thumbup:

i would this could be a good guess

Doing a search on this site showed ECO sometimes affecting power.

I try it on and off with NO difference in performance.

PS - I believe ECO does not affect Manual models (for it does not shift - only show arrow suggesting when to shift.

ECO mode affects a lot more than shifting...



This would be my guess also...

It did start after the idler was installed. When I take it to the dealer, they may need to remove or adjust it, to fix it. I will do an update when fixed.

The new rim is Can Am, and the tire is a Kumho - same size as OEM, so this should NOT be a factor in this performance problem.

Interesting. ...

The idler would not affect the performance at all. The fact that it started doing this after installing it would make is suspect that something else may have been damaged or changed while installing it or the rear wheel. The new rim and tire being the same as oem would also not make a difference and something could have been damaged at installation. The ECO seems a good place to start be it is on or the sensors/wiring involved have been somehow compromised. Does seem a good idea to get her hooked up to BUDS and see if something pops up that could be causing this. :dontknow:

Is it showing a code? Check Engine light? Did you check for codes?

 

[Tazzel]

I am surprised you needed a new tire at 10k. I am well over that and stock rear tire still looking good.
