Hi all

I've a 1971 GTR

Whereby the clutch had failed, the basket had cracked and the ring had displaced so I opened up the clutch side ready for the engine rebuild (part of the overall restoration I'm carrying out) to to have noticed the damage ringed in the two pictures.

Any of you chaps think the damage will cause problems.

If so any thing I can do to rectify.



Many thanks

I don't think those marks/ damage will cause any problems.. I would however sand them nice and smooth.. especially the top picture.. don't leave anything hanging that can fall off.. just take a dremel w/ a sanding disc to it and clean 'em up.
Happy Holidays!

This ^^^^. And check all your bearings and seals, and flush it out good.

That seal looks like someone punched it with a screwdriver.

Thanks for all the advice, all seals and bearings are being replaced during the rebuild. On another question if any one can help, what would be the correct (original) jetting on the 20/17 D carb.

Once again

Thanks

I usually throw those carburetors in the trash.

Thanks Tierney,

I know it's gonna be a slow runner when done but wanted to keep the engine as is.

Another one, I know I have a GTR from the VIN (VNL2T) , and the engine number (VNL2M) matches, but every reference I look at for the GTR has the engine down as a three port. The engine fitted is a two port, was wondering the GT was a two port (I think) and the VIN prefix VNL2T. Do any of you think somewhere along the line someone has dropped a GT lump in, in place of the three port GTR or if the GTR was made with a two port engine also ?

Ohh and more damage (see photos below).
Woodruff gone !!!

Koenig,

Your right, new crank, piston and head ordered. Although I still got a fair way to go, couldn't resist taking a little time out to do a mock up. Frame is ready for a full respray now after many hours of prep work. Colour / Color when finished will be Avorio (Ivory) 940. Am going to ditch the Cuppini legsheild trim and have the Piaggio aluminium one piece trim fitted instead. All in all it's been enjoyable and can just see the light at the end of the tunnel looming.
