I have the IWIS better quality timing chain.
Does this primary Triplex work well in the Norton primary ?
Is there a link if it does ?

Fired up the MK 111 after 2 days of rains. Full choke , 5 P.M. heat of 8 C. Shut her down after 5 mins. Let that heat soak into the motor . Helmet , coat , winter gloves. Drove around the hood up to 5 K. R.P.M. to check out the new chain and the new clutch mod. ( since I was in there with total tear down of primary ) of adding an interior plate to achieve an easier clutch pull. It worked , no slippage. Nice short ride dodging snowflakes. Chain works fine too , no leaks.
