Should I change gearing on Gixer 750 K5

[blackninja]

Bike has stock engine with stock gearing and I am thinking of going -1 up front .. in this shot I still had a bit of fifth and sixth to go as I eased the throttle so I should be able to get away with -1 on the front .. Is there a better option? How accurate is the speedo anyways at those speeds??

I doubt you'll see the top speed of your bike on anything but the longest straights.

Oh and worst I've just been to Le Mans shots I've seen so far this year

That was last year! ... this years have yet to be taken

I've recently done -1 on front and +2 on rear to my srad. acceleration is a bit metal
but i've lost quite a bit top end.

this also put my speedo well out but a speedo healer is worth every penny.

also consider it will slighty effect your mileage counter and fuel consumption....but its a sports bike so who cares

Think I'll start with -1 front and see how that feels ... may try +2 on the rear after that ... only for track so the latter is of little concern and it has only done 3300 miles from new

Fitted the gilles rearsets yesterday as well ...that'll save me boots!

Speedo is massively out at those speeds, mine was showing almost 165 when I was doing just over 150, until I got a speedo healer, then it does not matter at all what you do to the gearing
I personally went +2 on the rear and loved it, still had a decent top end and acceleration was improved.

OK ... got the gearing -1+2 with healer and now showing 146mph @ 12800 rpm in sixth ... anyone calibrated their K5 750 against a gps at this rpm/gear to see what it actually is?

Considering going +3 rear now as I tussled with a K8 600 which had -1/+3 and I had difficulty getting past on the stright .. so with fifth being revved out and sixth @ 12800 where I roll off methinks that -1/+3 will be the sweet spot for Le Mans ... which is where I was the past 2 days
