Hello Lads and Gents,
I just recently bought my AK550 and I absolutely love it (I've been riding a DT300 for the last 8 years with over 25k miles on it).
My scoot is equiped with the aftermarket J Costa variator, and I knew it has specific characteristics (high revs etc). What I didn't expect (however I should have, as I test driven a few AKs at the dealer shop before buying) is that the AK clutch catches rather high (on mine first signs of clutch engageing comes at 4500 rpm). The above mix results it the fact, that starting from dead stop or even accelerating ie from 15 MPH or 30 MPH (doesnt matter) comes with the revs going up to 6-7k (even if accelerating very softly).
Just to make it clear, I love the acceleration and 7k at WOT is something completely normal, however, it would be really nice if delicate starting from a dead spot or delicate accelerating would come with 1-2k less rpm.
Now the question: how is the best way to do it (I am ok with jeopadizing the performance a little, as the scoot has more than enough acceleration for me in every speed range). Would you start with buying heavier sliders for the J Costa? My first thaught was just softer springs in the clutch, but that i noticed this one has not a simple centrifugal scooter clutch but wet multidisc, so it would be way more difficult if no impossible in modding it to engage at lower rpm.
Thanks for all the tips and thaughts.
