F-Pro Shift Spring  -  Shift quicker and virtually eliminate missed shifts







The Blue Magic Shift Spring

$20 + shipping
(yes, in good humor, it's $14 for UPS Ground, even for a little blue spring
 - and we have to ship it tracked and insured.
I can't just drop it in the mail and hope and wish you get it and no,
I can't send someone down to the post office to mail it Priority tracked and insured)
You could pretend it's:

$32 and Free UPS ground shipping!

Talked to a guy who said this spring worked really well. Actually said he cut
over a second from his lap times just because he didn't have to
 worry about missed shifts anymore. He said he told all his friends to get one.

Hi Marc,

today my Kawa-Center installed the ignition advancer kit.

This is amazing, unbelievable how my engine runs now. I'm very happy
that I'd buy the kit, it's a big advantage.

Great work from you.

Have a nice day and best regards,

Roland



Adds more lowend and midrange -

Ignition Advance Kit - NOT designed (but usable) for 250!

But look at Roland's feedback to the left.

BUT!!!!
The ex250 uses a large, 3 bolt flywheel puller that only a dealer would have.
The woodruff key from the RTR-KAW-5-05 is exactly the right key for the 250.....

If you buy the RTR-KAW-5-05 kit, you can use the supplied woodruff key and the installation instructions for the ex500...... and you'll have a nice ex500 flywheel puller tool, too!
NO! You can't buy the key without the puller, I know you can't use the puller - but - as I said, I don't make a 250 kit......

Marc,
I really enjoyed swapping flying tales last week but what I really enjoyed was taking my bike for a ride on Saturday after installing your jet kit.
I started off with some trepidation since the 250 Ninja board is chock full of horrifying stories of repeated rejettings, needle raisings and lowerings and all manner of, after all that, very partial successes.  None of these concerns Factory Pro kits, however, and for good reason as I discovered.
I installed everything per the instructions:  3rd groove, install jets, 2 turns out (went out another half turn), and the bike ran well from the get-go.  I now have a midrange, thank you, and find myself cruising around at 7k (even as low as 4-5k if I'm trying to be really quiet) which is something the stock setup would not allow-at any rate it would not pull smoothly below 8k previously.  Full power is as good or better (My ass dyno is out of calibration, due to a boating accident I missed last year completely.)
I am delighted.  My brother in law is also convinced and may have ordered a kit already.  I'll post a recommendation on the Ninja site, but they're such bucks-down squids they'd rather waste the whole riding season than spend the bucks and the hour to get a fine running bike.
Thanks again.
Creighton Smith

Northern California's most unforgettable flying experience.  No experience required.  Open weekends!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
