14t Sprocket

[superjohn]

I think my M620 went from an indicated 125 MPH top end to an indicated 118 MPH. Not a big deal.
The low end is better.
Riding slow in traffic is better.
Gas mileage went from 50ish MPG to 45 MPG
Steady on cruising on the Interstate puts the motor at about 6200 RPM at 80 MPH, which is a bit buzzy. I try not to do too much highway time on the Monster now.

I'm thinking about doing this mod, but how hard will it be to install with my limited wrenching experience?
Is there a guide anywhere?  I don't mind experimenting, but don't want to screw anything up.

That's for the S2R800 so the chain tensioning part is probably specific to the single-sided swingarm, but the concepts should be relevant.

That site is cool - and the best part is I had no idea my 620 would do 205 mph!

 Speaking of which, has anyone seen Randall here yet?

Actually, I believe it depends on the bike. The DS motors have a big single nut that almost absolutely requires an impact wrench (or really big breaker bar).
The other motors have two allen head bolts that are easily removed.

i find that i hardly ever use 6th gear anyway (not too much opportunity for going those speeds these days), so the 14t was a good bargain for me wt:

I find that I don't have a 6th gear, but that's not important.  Sounds like this is the perfect mod to cure my hiccuping at low speeds.

I hardly notice the diff,it's great in the city though.Plus how fast can you go in the twisties

Yeah, Highway riding...  co::

I did 3up in rear on my M900 only downside was the track, ended up between gears at a couple of tracks like VIR, therefore I kept my S2R1000 stock and use it for the track. With the mod to the M900 I find it way more fun in all the twisty stuff I have found in VA, WV, OH, TN, NC, GA.

Is there a definitive thread somewhere that talks about the best way to go for gearing down a monster?  I hear a lot of different methods people use like -1 front, -1+2, -1+3, etc, and it seems like swapping out the chain is sometimes needed, sometimes not.  I tried searching but I can't find the "best" resource that has all that info.

The reason most do a 14T front is they do it early with a new chain and don't wnat to replace the chain, if you did 3up in rear you would need a new chain. I believe most would agree that when you are ready for chain/sprocket replacement, do the rear. There was a thread in another forum that had a link but I cannot find it right now.

Interesting... I am thinking of replacing my chain anyway because the prev owner lived near the ocean and salt got it a little corroded, plus he never rode it so it sat dry for a long time.  And, let's be honest, a gold or black one would look great on my all black M1000S   wt:  is it recommended to do both 14t in front AND 3up in rear, or would just the 3up in rear be best?

[twolanefun]

Believe the M1000 is same as an M900 gearing wise, going up 3 in the rear for me was perfect, since I don't use it on the track anymore, I wanted 4th-6th gears to be useable in the twistys. With the ecu, airbox, and termis I move the torque curve down to around 4K RPM, but with stock gearing 5th/6th was almost useless on the back roads.

[Jnaids07]

Cost is definitely a major factor. I found it good to go 14t first to see if I liked the feel (I was skeptical).  I have now found that I like it and it only cost me $25 to learn this.  Maybe i'll go back up to 15 and +3 rear when I get a new chain/front sprocket/rear sprocket. 

The real advantage to going with a bigger sprocket in the rear is that there is less of a chance of the chain damaging the swing arm from chain rub, and there is arguably less horsepower loss in the drive train. 

Anything else?
