Featured Cyl Head Refurb

Found a suitable correct year head for my 70C at long last and had Patric at Seager Engineering sort the ex ports valves n guides for me so i can now finish the bikes off properly

 

Thanx. Exciting bit is getting it fitted next week and finishing off the job as i should have a few years ago instead of making do with the head i had at the time

 

Yes this one was some dry glass bead blasting, same result

 

Managed to get the engine cleaned off and get the bike in the workshop and remove the cyl head A bit more cleaning and prep then the refurbished head can go back on.

 

Head back on and one heat cycle, will retorque head and adjust tappets next week n finish off the job.

 

For anyone doing a similar job, some factory info on head to tube seal crush. Figure given for crush is with gasket in place.

 

I run my engines until i feel warmth in the oil/tank and some times use a fan if its warm, sorry if its a bit vague but that what i have done for years,

 

In between striping a pre unit 6T for a rebuild i finished off the head job at last.
