Suzuki 2 Strokes

Both Heads have a crack running from the plug holes.

This is the worse of the 2.



Any issues with welding?
Cheers

Hi Richard,

It has been a common practice to fill the combustion chamber with weld and then to re-machine to create centre plug heads with a proper squish band so if done correctly welding up a crack should be no problem. The hard part is to find a competent alloy welder who knows how to weld M/C parts and can re-machine the heads afterwards.

I know a motorcycle race engineer in Doncaster who could do the job (he could also convert them to centre plug ) or alternatively seek out a pair of replacement T/GT heads.

Cheers Geoff

Cheers Geoff, looking closer can see it's run up the threads through the head.
Already spent a bit so might as well get some heads and get proper repairs if needed.

Heads are going around £50 each I can see but not sure!

Hi Richard,

They could still be repaired, and a good opportunity to make them into race heads at the same time . However I think sourcing replacement heads is the best way to go, £50/each is a realistic price. I might have a spare pair myself but I will have to check, gave a set away to a friend a while back so not totally sure.

Cheers Geoff

Hey could you give me contact details of the motorcycle race engineer in Doncaster who could do the job?
Would me much appreciated Geoff.

The only heads I've seen are on eBay so couldn't know if they are suffering too.
