Crack in cylinder head when tacho gear removed

I got a crack in the cylinder head when I removed the mechanically driven tachometer gear. The crack caused bits to fall off the mounting hole of the tacho gear.
When I put it back in the rubber seal barely covers the gap caused by the missing bit in the cylinder head.
Any ideas how to fix this ?
I dont really want to replace the whole cylinder head.

Do you have any experiense off chemiacal metal ?
One alternative is to put it back in and then seal it up with that stuff. Or weld seal it up with weld.
Got some time to make up my mind. It´s winter in sweden now so I have 5 months to fix it.

Is it two components that are mixed before application ?
Time, I get you, less hassle to weld i shut and go with a modern tacho.
I´m building a modern cafe racer...sort of. Will do the modifications that I feel like. Planning a GS swing, wide back tire and some glas blastering since I just bought one
Would like to keep the original tacho since it keeps the retro feel.
Heres some pix:
#1. The bike when I fist saw it.
#2. After first reduild
#3. Breake down, winter reno

Unomike, will check JB Weld out and see if I can get it in Sweden. Might find something similar.
Is it two components that are mixed before application?
Yes, Part A and B. Good Stuff. Should be available in your country. There are other products out there that claim to be as good as JB Weld. But I have had the best results with JB Weld. Keep me posted with the repair!

Did a search and saw that JB Weld is the only one that works for temp up to 260 degrees Celsius.
Found it at the US Ebay at first and then a small importer in Sweden that stocks it !
Will buy this and some other stuff.
Will get back to you with some pix when I´m done. Will take some time since this is the last thing I´ll do with the cylinder head.
Thanks again,
Arnold
