I have used this lever from rgm on both my 73 and my wife's 75. It is both longer and is closer to the grip. I did have to grind the part that engages the piston slightly to allow the piston to return completely.
Tough call on the lever. Lawrence of R.G.M. replied stating he felt their improved lever would probably not work . I thanked him for the honesty as it would be 51 pound plus shipping and duty. So I pulled the stock lever and filed down the fulcrum point where it touches the M.C. piston itself. Seems to get the handle closer to the grip with 4 fingers involved now. In spring I will give it the driving test , if not happiness then will look for a dog-leg type lever at a local motorcycle wrecker that fits in the spring when shops re-open again.
The motor is smoking , as purchased. The motor smokes badly intermittently , meaning sometimes no smoking then say 10 mins. later badly for 20 mins. then back to no smoking. Both plugs are oily. I'm going to have to pull the head as a minimum. I built a cardboard protective box today to place the tank into to protect the paint as first step is to pull the seat and tank before pulling the head for inspection. It's a .20 overbore. I'll look for an oily headgasket and then valveseals first. Wish me luck.
Keith Newton here in Toronto did the rebuild. No way to contact him I am aware of. I don't want to place blame here .. but she's a heavy intermittent smoker. Probably cancer . Ha. There is a welded up R. side case hole. I never noticed it in my enthusiasm to purchase a cosmetic and 8 time original show winner. Later , I found out it blew a T. side rod. It needed the small weld to the case. It needed an undersize crank grind and .20 pistons. Both plugs black evenly , and oily evenly. I'm hoping at best the intake seals are shot. I'm hoping it's oil flooding from reversed rocker shafts. RH4 head could be cracked by bad intake guide install too but both plugs oily. Bad headgasket ? X 2 unlikely. The MK111 has a vapour recirculation system so ? Once I parked it running on the sidestand and lots of blue smoke from the right exhaust. If I level it, blue smoke from both. But I can drive for awhile with no smoke. Sounds like head -floodings. Drain passage blocked ? Tomorrow I will pull the tank and prep for a head pull. Labour.
Forgot to mention Joe Peck ,myself and Jack Sennett took a nice drive out to visit Rick Harritt at Highway Cycle today. Saw a lot of Triumphs and Nortons and BSA 's all in various stages of repair. The best was a long poem , outside in the spring sun before leaving . We clapped ,then went for food and booze in Waterdown.
Private seller , no guarantee written. When we started it up and it smoked he said probably needs new seals. I said probably or likely needs a valve job. He said I can help you with that , the implication being costs seeing as he is in another city. He's a good man , honest and careful. I recently told him I will not re-insure the vehicle until this is fixed. That's where it stands.
