The Piston Broke / Re: NOS?

No not casting. That part would be drop forged, significantly stronger.

You've reminded me with NOS

Couple weeks back recovered my seat, with cover I got back in 81 from Fowlers, last they had. Really pleased with myself how well it came together. Turned it over and realized the YAMAHA logo was 3/4" off center.  >:( Will the Rivet counters class this as originality, do I get extra marks.
Anybody following me will say look that logo is off center. :-[

Yes it came in an original bag with the correct Yam sticker and part number.  Are they a casting and tube that are welded together? The photo shows the back which can't be seen when fitted - the front has had the weld mostly polished out.  Sounds like it's about par for the course, thanks guys.

Yes - that is genuine NOS Yamaha quality

One on my 400C is original and looks much the same.

They never worried too much about finish quality back then.

Just in case anybody else is having the same problem as I did, the wires for the indicator switch had semi broken off that's why I was getting intermittent indicators, I took the switch to pieces and took the plastic block with the indicators wires fix to, cleaned the holes, tinned with a little solder and the same to the wires, its obvious where they solder to because of the length of them, they can only go one way, got a pair of fine tweezers and solder the wire onto the block

On my yds7 and yr5 no reeds, plain rubber manifold between carbs and back of barrels.
Good to know you use the sealer for a similar purpose so thanks.

Machine enamel works fine warm your carbs and paint on a radiator first and it dries quicker.Alternativly you can leave in the sun to bake on  ;) unless you live in scotland or ireland :) :)

Hi Neil,

Who makes the machine enamel that you recommend?
