engine mount

akcalhoun · January 22nd, 2013, 05:18 AM

would the 300 front rubber engine mounts fit on a 250? would be nice to cut down a lil on the buzzing

lgk · January 22nd, 2013, 07:13 AM

i doubt it, the frame and engine are different.

what part of the buzziness bothers you?

tubarney · January 22nd, 2013, 07:21 AM

from what I've heard the rubber mounts do nothing.

Something loose? I don't hear a buzz from the bike itself, just the buzzy sounding exhaust. It's common for the levers to buzz, does it come and go at specific rpms?

akcalhoun · January 22nd, 2013, 09:23 AM

its mostly the footpegs they can get kinda buzzy at highway speeds the handle bars a lil too

Still running stock gears on the hwy?

csmith12 · January 22nd, 2013, 10:02 AM

So it safe to say it's the buzzy feeling vs audible sound?

Some things to think about.
Comfort grips and aftermarket clipons that bolt to fork tubes instead of top tripple.
Heavier bar ends
Rubber coated rearsets (you have aftermarket?)
Gearing
Preloads on suspension (what position do you have the rear set to?)
You have a tight grip on the bars? I would agree that the bars get buzzy at around 80, it reminds me to be loose
44lbs of air in your tires? Try a few lbs less. Sounds funny but I am not joking here.
Super hard touring tires?

akcalhoun · January 23rd, 2013, 03:29 AM

grip on handle bars is loose, im constantly berating my riding. but i am running stock gearing and every thing else is stock (foot pegs ect.). have been srsly thinking of goin up one gear on the front and if it helps the buzzing at highway speeds i think i may finally do it soon.

One of the best mods you can do. The Ninja becomes a new beast with a 15 tooth front sprocket. It should reduce your rpm speed by 500-700 in any gear, add approx 6 mph to your top end speed and reduced a bit of the hwy buzz at higher rpms. Switching to a synthetic also helps smooth out the engine.

csmith12 · January 23rd, 2013, 10:05 AM

Yea, try the 15t front sprock. I think that should be the stock gearing. $20 and 20 mins worth of work and easily reversible. You don't even have to bust the chain.

lgk · January 23rd, 2013, 10:44 AM

the 15 tooth sprocket should help.

get a cramp buster and some foam grips.
wear thicker socks

tuck a little once you get up to speed.

akcalhoun · January 28th, 2013, 05:50 AM

just put on a 15 tooth sprocket, and it rly helps and i love it. i mostly drive hwy to commute and yes its a great mod shouldve done it earlier.

LNasty · January 28th, 2013, 02:35 PM

I heard that switching to the 15t can damage the bike in some way is this true? Also how hard is it to change out? I commute everyday mostly hwy and my rpm's at 70 are at 10000.

Not true, however a 16 tooth sprocket (which some have done) will make the chain rub on the sprocket cover.

The install is not hard at all. There's a DIY somewhere.
You should be doing closer to 80 mph @ 10k rpm (in 6th gear) with stock gears.
Installing a 15 tooth sprocket, you'll be doing closer to 70 mph @ 8k rpm (in 6th gear)

Why is my rpm so high then with the stock sprocket? My idle is set at about 1300. What can I do to fix the high rpm in 6 gear other than switching sprockets?

if all our transmission gear ratios are the same, it should equal any stock bike with 14/45 sprockets.

you can 15/44 for an 9% reduction in rpm.

LNasty · January 29th, 2013, 07:43 AM

That still doesn't answer my question of why my don't are so high

LNasty · January 29th, 2013, 08:17 AM

2000 miles
At 65 I am at 9500 rpm

lgk · January 29th, 2013, 08:20 AM

2 things come to mind for this:

You have shorter gearing (13/45 or 14/47) because that is about the same rpm's I was turning when I was running 14/47 gearing
You have the newgen-rpm-readout-issue that is just part of the newgen CDI on some bikes.

LNasty · January 29th, 2013, 09:08 AM

Ok, I will count the teeth on sprockets
