Got it. ThanksAlisoBob wrote:The number of teeth on the gear isnt divisible by the number of splines on the kicker shaft.
If you install the gear differently from wher it should be, the splines will "move" to place the kicker in a different position.
Kinda' like a vernier scale.

Well, Cracker rode off in fine style on his Gen 3 A/F....
Motor is a 90'... had a Weisco in it with a smeared bottom ring. ( Bridge non relieved, no lube holes...
) We Nigivered it with some sand paper and a file... good as new. Motor has tons of compression now.
PULLS HARD!
We did a little tuning on it, new chain, brake pads and bars... Ready for Steiners place tomorrow....
Congrats Joe!!!!
After it was all said and done, Joe figures $1850 went into it...... NICE!!!
**** DOES ANYONE HAVE AN 18" WHEEL FOR THIS BIKE? ****
Is a 2002 CR250R Let me know.... Thanks!!!!

That bike looks really well done. What I like best about it was choosing to use that '90 motor. I'd sell a kidney to see Cracker put a hurtin on a 450 with that "well seasoned" mill. Heres to your 18 yeas of R&D blasted right back in your face, BRAAAAP!
Again nice ride
Seems like a lot of us now, wish I would see more 500 riders around...

Big thanks to everyone on the site. I received help from allot of people on this one. Thanks to Mad Dog for the 02 CR, it was very clean. Thanks to Shan for all the info and parts. Danny for parts and info, and thanks to Bob for being my best friend and the best friend to the CR 500 community. I will give a first ride report after tomorrows ride.
Cracker's bike did real well today.... about the only two issues were the carb...( real lean at idle, surging ... then instant rich at 1/8th throttle, chugging...) and 220 psi in the front tire.... Make handling a little spooky...
Other than that, no issues over 19.8 miles of messing around.
Vibes are nearly non-existant.....

nice job!
it looks good for sure!
just some random on the kicker position in gen 3's,
as mentioned by others,,
you'll find that there are index marks on the rachet gear and on the shaft.
those should be aligned.
you can try other positions for clearence,
but odds are the best postion is goint to end up at the stock indexed marks.
the thing is- that if yoi udo a bunch of these ( i think ive built about 800 gen 3's?)
you will find honda CR500 kickers are not consistant in thier shape.
(yes they all look identicle)
try 5 brand new kickstarteers ..
on the same gen 3 bike /same shaft postion ,and you will likely have
at least 3 different arm locations were it gets close to the frame.
my guess is that while all molded the dame,, they are prhaps pulled from th mold differently, or cool at a different rate ,causeing the slight differences.
it "could" be in the broching of the knuckle itself..
but i have swamped out brand new knuckles , on the same earms,,
and had the same shaft /arm variences -
so at least i nthese cases it was in the arms themselves.
bottom line is-
some will clear by alot, others will tend to rub the frame,
and need clearenced in some form.
you can go thru a bin of 20 or 30 new kickers-
to get lucky with one that "fits perfect"(most will rub slightly)
I have claearenced them slightly, and never had the arm fail.
if i find onne that seems to need more clearencing than i' m comfortabe with,,it simply isnt used.
Good luck and i hope this tidbit helps for those that might run into this minor detail..
