I have a '74 Mark II Roadster I've owned for 11 years. Within the past 700 miles I've noticed excessive oil consumption with
some blue smoke until warmed up and then no noticible smoke. It has used 3 pints in the past 550 miles and doesn't leak
oil :wink: . The plugs are oily and black (NGK BPR7ES). I'm running a Mikuni 34 MM with needle clip on the top notch and a Boyer Ignition.
The compression warm is 105 lbs/105 lbs WOT. There are 21,656 miles on the original bore, 9,000 miles on a bore hone and new rings, and
9,000 miles on a valve job with new exhaust valves and seats, and new intake valve stem seals.
Bike has gotten hard to start but once warmed up goes like a scalded cat. Idle and just off idle it is rough. The compression and oil
consumption bother me and I plan to disassemble the top end for an inspection. Aside from the following items, what else should I
be looking at while it is apart?
Bore; Rings; Valves; valve guides; intake valve stem seals; seats; springs.
My kicking leg is getting palsied due to age and I'm seriously considering the new CNW electric start conversion.
