EVO Shift STAR kits < click there for more info and ordering
Nothing simple about testing and designing this copyrighted kit at all.
Oodles and oodles of different STAR arcs, angles, radii, major and minor diameters were tried on multiple bikes to get the best feeling, best performing design for each bike. In the end, it's what Marc (yes, the same Marc who was the early 80's "World's Fastest Vegetarian" roadracer ) demanded in "shifting feel" and response.
The EVO STAR kit does the impossible - it makes shifting quicker, virtually eliminates missed shifts, removes clunkiness AND is easier and more reliable to shift than stock.
Fixes notchy zx10's, 12's and 14'd and lazy shifting ducs, Aprilia's, Kaws, cbr's and gixxers. Hayabusa's stop shifting like a truck and now shift like a dream on street and track, with or without the clutch - at 2nd gear, in-town "cruise" and when "bangin' downshifts" into that 160 to 20 mph corner or "trying for that last 10th, "bang into second" shift at the drags........
Prices range: $139.95 to 199.95 (depending on required components)

Pro Shift Kits < click there for more info and ordering
The simple "roller bearing detent arm, FPT arm spring and a gasket" kits are designed to get rid of most missed shifts, are about 10%-15% firmer than stock to shift, but do the job of speeding up shifting and help keeping missed shifts from damaging your gears. Firmer spring to speed up shifting and less friction with the roller bearing to let the shift drum move quicker.
price: $89.95

Transmission Detent Spring Kit < click there for more info and ordering
(Shift Kit? B&M owns the "Shift kit" name - so... we don't call it a "shift kit'!)

The budget minded "spring and a gasket" kits are still available for some of the older bikes.
price: $39.95

Marc,
Your timing is perfect - I just rode it today for the first time since installing the vfr750 Shift Kit. Outstanding! I had read posts on the VFR sites about how it was so stiff and much tighter than stock, so I was expecting a difficult transition. I found it much more positive than the stock, I did not get any false neutrals downshifting to first, and It felt butter smooth in all gears. I have been wrenching for years and I followed your very detailed instructions carefully. I will admit that shifting through the gears with my hand on the shifter was more difficult than using my boot! Thanks for a great product!
Regards,
Dave Peins

Comment: My experience is that the VFR owners who used our microbearing detent arm but decided to not use the supplied spring and, instead, used the stock spring were often the guys who rode in cloth-topped athletic shoes. That's ok, because, even with the stock spring, it will still be better than stock shifting. Marc

Nice talking to you and all that a couple of weeks ago.
I have done a few hundred km's with this now and I have to say it is a rather pleasant improvement.
I have always thought that the shift on a Busa is a pretty good thing when compared to earlier big bikes like the ZZR1100 and even earlier still the VF1000 but it is still a much meatier affair when compared to modern bikes of smaller capacity.
This changes that somewhat. Not quite as sweet as say a CBR600 but along those lines.
I like the way that you can do lazy up changes around town without the clutch and it slips through as smooth as silk.
Also it is not that difficult to install either as long as you have the gear to get the front sprocket nut undone (a rattle gun is handy) and you are prepared to bend up a ring spanner so as to get that one gearshift housing cover bolt that is a bit hard to get at.

Hi Marc, Just wanted to let you know that your EVO-7 Shift Star Kit ROCKS! I've been having problems getting a lot of missed shifts between 3 & 4th gears in my 636 and after installing your kit, the problem is 100% GONE. I raced out at Streets of Willow this past weekend and didn't have one single missed shift anywhere and the positive engagement feel is perfect. Thanks for making my 636 an even better bike!

Mark:

I got the Pro shift kit installed, and it works like a charm.

Thanks Marc... I got the parts and they are already installed into my bike.

It was amazing what a difference the shift star made into the bike!!! :)

I'm waiting to get the bike tuned on the dyno to see what is the affect of velocity stacks. :)
