Aye Steve,

I see Dave's getting misty eyed about his 'baby' and he has my sympathies, having written this afore, "I realise that this might destroy the 'Tiggy' frame, with the jack hammer vibes you might release. Crank balance factors etc!!".  ;)

The solid gears, properly tempered, maybe a better way to go. But why did Yamaha put a shock absorber in there in the first place?  ???

I may have a spare pair from an SRX, but suspect you'll be wanting to stick with an SZR or XT bottom end.

SteveH. I knew I'd seen it somewhere and you've hit the nail on the head.

SteveL. Maybe have a look and a blether with these boys as well!  ;D : http://www.barebones.net/machines.htm

All the best, Bill.

ok, got the sprockets off, reason the balance shaft sprocket was a s*d to get off was because it had been forced round the shaft by 10 thou, notching the key slot, and stepping the key!

So, items to be replace (so far) both sprockets, and the balance shaft + of course the nuts and lock washers... getting expensive!
whilst we are on the subject of lock washers, you can see from the pic that one of the tabs on the washer is broken off... more than enough to mesh into the gears and cause all this damage..... maybe

I once saw a TZ framed FT500 motor racer that pretty much disintegrated after just a few laps of practice at Snetterton. The counter balancers had been removed - I think we counted at least 14 cracks in the frame  :o

Not sure, it really needs a SZR or XTZ660 parts list to be certain.

Hi Steve

The top end of that motor is 34K.  Not sure if the air cooled and liquid cooled bikes used the same balancer.  I suspect they did.

No gear on the shaft just now, but I believe I have a pair of solid balancer shaft gears.  Would you fancy?  Supposedly make a hell of a racket, but guys seem to favour them over the "cushed" balancer gears...

I was keeping them for the skorpion if needed, but you seem to need them more than me just now!!

Cheers for now, let me know,

a

cheers andy..... lets wait until i have the motor split, and assess the total damage, might be that i put it back to an srx bottom end, or rebuild the XT bottom end I have at the back of the garage.... which may or may not have all the bits i need!..... just remembered it....thanks for reminding me  :D.

I'll check it out tonight.

Hi steve

Apparently the major "plus" of that bottom end is the nice close ratio cluster in there.  It may or may not fit into the "aircooled" cases...

Just incase you didn't know and junked it!!    :o

Let us know if you need anything.  I asure we have enought between all of us to get it back running many times over!!  Would be interesting to see the differences between the two different bottom ends... I had assumed the 660cc version would be meatier, but I dont know.....

cheers
