hi all,checked my timing on my 79 today and was about 3 deg avanced, to adjust it acording to my manual (haynes) you access the 3 screws that hold the stator thru the slots in the rotor, the only problem being that these screws apeer to be blocked by the outer edge of the rotor and a tight fit between the windings. with the history of bad stators i'm reluctent to force a screwdriver in to loosen these screws(or to say i won't) but iwould like to get all i can out this fine engine. any thoughts or advice will be apreaced. thanks in advance, Bob

Mate, I'd be taking off the flywheel and doing it that way...you can always place the flywheel on again loosely to check it's OK before fully tightening it again...from memory I think that there's not a lot of adjustment anyway...I'd have to look again myself...
Oh yes and don't be tempted to replace the screws with allen headed types...they'll hit on the inside of the flywheel rim...I was going to try the lower profile button-headed allen screws when I next remove the flywheel...they may work.

I vote with Stew. My new Cycleserv manual (which I won by filling out the competition coupon in Just Bikes magazine, would you believe!) says to take the flywheel off. The picture sure looks like the stator cooils are in the way. Mick

My Clymer manual also say's to remove the flywheel to adjust the timing. It gives a flywheel puller Yamaha part number (90890-01189)

Hi.
The flywheel puller is worth having in my books...I used to do what a lot of others do and try to lever things off, etc...it's not worth the risk of the possible damage you may end up doing to the cases ...
My old RT1 360 two stroke could be done that way (...using tyre levers)...that flywheel often needed to be removed due to snapping woodruff keys etc. You knew that if you were kicked back hard the key would break or have already broken previously...what 'painful' fun....
Bikes who'd have 'em....heh, heh...

You can buy a cheap puller from any decent parts store - I got mine from Pep Boys - just get the kind with 2 puller arms, not three. The flywheel will pop right off with good pressure and maybe a GENTLE tap from a rubber mallet.

Hi. I'm pretty sure they're exactly the same....one thing though...use grease on the thread for the flywheel and on the thread on the bolt. It's a lot easier that way...You'll still need to tap it as well.
If you have the right tool the job is so much easier!
Good luck with it.

Stew, just to be sure the nut retaining the flywheel is a rh/normal thread, correct? you are so correct about the tools! if people knew what i have invested in tools they would lock me up.i love my tools ,it's a additiction,i can't help myself,thanks again, Bob

It's a normal thread. I've had mine off about twenty times this month...

Yes it's a right hand thread...unlike the puller thread into the flywheel as I recall...it's left hand.

DUDE!
Be very, very careful with an impact wrench . The backing plate for your stator is crappy "pot" metal. Mine broke right across the screw slot for no reason i can figure other than fatigue. And they are a stone pregnant dog to find and replace - trust me.
"stone pregnant dog"...ROTFLMAO ;D

Thad,if you did'nt notice i said hand impact, works fantastic w/stubborn hardware ,if you don't have one you need one! diffrent beast than an air impact. i hade a1/2"drive one at home but was too tight to the stator so i brought a 3/8 drive home.worked like a dream! and how lucky can i be(don't awnser that after the day i had) but i hit the timing dead on the first time.anyway you got your dog high and did what??
