There,.. I fixed it...
04/29/12 at 13:38:23

My wacky, angle grinder press did the job... Wink

...
Oversize pulley is running true now...
My thanks to MMRanch for finding it,.. and other members for throwing out ideas and suggestions...
If anyone else is contemplating the swap... keep in mind, it's a lot of grinding, and the end surface must be made true flat...
Pulley is 25 tooth, +2 of stock,.. from a Kawasaki LTD454...
Yippie!... Grin

...

The rig...

Pulley installed...

the movie...

Reply #4 - 04/30/12 at 18:51:55 I must admit, Sir, that when I saw your angle grinder/drill press/thing-a-ma-jig I thought Red Green was hovering over you, but I'm very impressed that it worked!! Congratulations. Guess that $5 pulley was worth it after all! Let us know how you like the ride!

Don't forget to build in the cost of a new grinding disc or two with each one!

I have ridden local, (under 50mph) for 30 miles or so.... No noticeable difference in low end take-off... .. but, more belt noise.
I had the old one dead silent...
This new pulley was pretty rusty in the teeth... hoping the belt will buff it clean, and quiet it down, with some miles...
Gonna' put 500 miles on it, and inspect...

Maybe not 100% trued,... but, eyeballing it, I can't see any wobble...

Will update...

Good question.... Grin

...

I haven't... These are theoretical numbers based on the Gearing Commander program... calculating the speed with this gearing at redline...
I'm mostly interested in a lower rpm at 60 to 70mph cruise...

I do have my bike well tuned, lightened and slightly modded,... and I'm pretty lean at 140lbs...
I have gotten up to about 94mph (actual) on flat...
I've done a few mods since that time, and with the gear change, I just might get to 100mph... ... if I do, it'll only be once, to say I did it...
That's way too fast for this bike... Huh

...

It's a personal challenge for me to get this bike to do "the ton"...
For no reason other than, I'm an Ace Cafe' history buff...
... and I'd like the status of a "ton up" bike...

I realise it's a way too easy feat on a majority of modern bikes,... but it presents a perfect challenge on this one...
The other part of the challenge is,.. I average about 62mpg... and I'd like to keep that at least over 60 mpg...
It'll be ridin' the ragged edge to manage both...

At heart,.. I'm more of an efficiency buff, than a performance buff...

A favourite expression I read once... "Tucked in like paint"...
I just might manage it, if I can "tuck in like paint"... Grin

I'M TOTALLY DOING THIS ONE!!!

My CS1 has a 96mm piston and the Web cam and with the raptor petcock, every 45 miles I'm flipping to reserve and heading to the gas station. My build will love the 25T gear. I hate seeing 5000+RPMs cruising around 80mph

Also, what exactly did you have to modify? The offset on the pulley was wrong? Clearances to the engine case? Easier to modify on a lathe if you have access one?

RycaS.. got your PM, but here's the original post from MMRanch...
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1327470630...

... and my earlier update...
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1334871333

I bought mine at a junk yard...
I haven't decided if I like it or not... Maybe I'm just too used the the old shift points after 6 yrs...
I used to gear up all my bikes, but I never waited 6yrs before... it's very awkward on familiar roads...

Looking forward to the lower revs at 80mph! How much would you say your rear axle is displaced forward compared to the 23 tooth pulley? - NM! just finished reading your thread

Well,.. visually, it looks to be running quite true,... but I am hearing more belt noise than I used to... Unfortunately,.. while I was installing, I also decided to mod the cover plate, so I'm not sure if that's part of the noise increase or not...
Shift wise... definitely higher gearing... 4th now feels taller 5th used to...
I've noticed uphill mountain roads, now require a specific gear... where there used to be some overlap... every turn, I am running a gear lower than I used to...
... can hit 40mph in 1st easy... 60 in 2nd,... 85 in 3rd,... 4th?... ...5th?...
Of course, this doesn't show on the speedo,.. because it's geared to the engine... sets speedo off by 8% over... so, careful... don't get a ticket...

Still debating whether I like it or not... going to ride with it some more, and see if I settle in to the rhythm...
Just had to find out... irresistible option...

PS... you may need to replace a sidecase bolt at the lower rear of the front pulley... it was contacting the belt as it left the pulley... I used a roundhead allen type, and had to grind it a bit flat on the head... ..but, I also have 12" shocks...

Good luck.. Wink
