Yamaha / Re: TT500 chain & sprocket ?

A dirt track friend of mine, now retired, locked the clip in place with a piece of steel beer can slipped in behind the clip and folded over the top of the clip, any excess trimmed off, with just enough left to push in the space. Bit fiddly but it worked.

Vintage Track / Re: CAREFLIGHT Aug. 20th-21 Nepean Classic

Pre 70, pre 75, pre 80, pre90. all there, and a good field of sliders. Track was great , Super Seniors great, lots of fun! Fair few overnight campers, the whole annual Classic Dirt Track Charity event is firmly established in the annual Dirt Track calender. Would have been good to see a few more overnight stayers, interstate entries and outfits as in previous years. Careflight had volunteers collecting gold coin donations on the Sunday morning to add to the total of donations from the event. Nice report in the local "Nepean News" colour paper.. The two 25 lap events on the Saturday were good to watch with close racing right to the line. Brett Glover got the Pre '75, and Clinton McDonald took out the Evo Open.
I got the Super Seniors (over sixty fives in this case).
cheers pancho.
ps. thanks to Roy Gay for his hours and hours of effort.

Standard bore size, '79 YZ80?
How to test for leaky reads? I poured carby cleaner in the port a bit dripped through, is any leakage permissable?

(Hate 2strokes)
Cheers

Tech Talk / Re: Cant get the stator rotor off!?

« on: July 21, 2016, 09:33:44 pm »

I had one I couldn't get off with the standard puller.
Or a claw puller
Or with "oxy assist"
So, WELDED two 1/2 inch bolts to the flywheel(which I had long given up on) put a very solid cross head puller on, plus more oxy. broke the welds again.
Re welded the bolt poored more penetrene on put the thing on max tension again and left it on the floor for about six months.
Got the urge again not to be beaten , hit the head of the puller bolt one more hit and BINGO! I win!
The cause of this was I dropped a chain at Nepean at revs, the chain jammed at the sprocket, it went from revs to instant stop. Since I don't use a key the flywheel turned and welded to the shaft. Of course I line the key up just to retain correct balance.
