Excuse the hijack fellas. Bytehead, this custom 61 tooth rear pulley you mentioned....could you give us some info, if not the Scootworks. I want so bad to do something about the eyesore Kawi put on, but we don`t have many choices. I sent an email to Barons suggesting that a chrome cover would be worth their while to fab up, since a ton of us 9`ers would gobble them up in a hurry, but never heard back. Would love to see what what you have...thanks!
I will get pic later but think of a solid disk with a pulley on the edge, no cut outs and no chrome just polished solid disk. Not pretty but i use saddle bags so you cannot see it anyway.
It is actually a blank for an HD that is used to make custom pulleys on a cut out machine.
I live in the Dallas area and found a custom wheel and pulley shop. Paid them a visit and explained what i wanted and they whipped one out, drilled holes to match my old pulley and mounted and shimed it.
Now comes the gotcha, a 61 tooth is one tooth too small to use alone, the belt will not tighten up so you get lots of noise from the loose belt. After the SWP front went on the belt is perfect.
I got the custom work done for 300 and am glad to get it done.
Keep in mind I also have a DARKSIDE rear tire at 195/65
OK here are the numbers from gearingcommander.com
rear 61 tooth is 6.6% difference for -249 rpms at 70
rear and front is 13.23% difference for -542 rpms at 70 = 3550 rpms at 70
top speed calculated for both pulleys is 119mph
One point of interest is the New SWP the reworked one is PERFECT no noise at all. But DO NOT order it from SW get it from MEANCYCLES.COM yes i had nothing but trouble from SW.
Now 70 is smooth.
I cannot attest to trying this combo out with a stock engine setup. I have jacked my HP up to 57+ ( it is possible with the right combo). But I have no prob with take off.
Also keep in mind for dyno test that the overdrive pulley will show less HP than reality so just add the percentage back and you are good.
Ok with that let the doubters flaming begin.
Any one living in the Dallas Area is welcome to test it out just give me a shout.
