Hi all,does any one possess a quaife 5 speed gear box as i would like to borrow the camplate in order that i may copy it.Thanks

PeteC, Idie, thank you. I'll have another look at crank pinion. No, i know there's nothing on mag pinion, i remember timing up from way back, but i never had occassion to take off a mag or other pinions. In the late 60's, early 70's M's were still "current" bikes, the mags an stuff hadn't yet died. I remember when a mate bought a 500 kwacker triple we had im on the corners every time. U could actually see rear jumping out in little hops. Scary. Russel motors, sounds familiar. Ok, 'll just look at link, an get onto those two. Will update you. Y'health, Mark.

It’s still in build stage at the moment, bottom end is together almost, just need to save up for the Bob Newby Clutch basket (I already have the front portion as it was sent away for balancing)

The bike was a us import with no nova, so I’ve had to assemble to to make sure everything fits etc before I strip it again and do all the paint. So hopefully sometime within the next 6 months should
See it on the road.

I plan fitting a 928, but the pair of 928’s I have, have gone walk about so it might be a 930. It’s got an A10 crank, still using the TS Bush, crank is balanced, but don’t ask what factor, I have a load of paper work with all the weights etc but it doesn’t state factor, but I assume i can work it out from the numbers on there. Bassett down did the balance work. Pistons are 79mm JE B44 pistons I bought from PES (aka CCM Great Britain) and I’m using a John Hill Alloy barrel. It comes with 2 gaskets so you can lower the compression if you wish with the thicker gasket, as I’m using this as a tourer I want the compression as low as I can get away with, trying to balance a bike with a passenger and luggage isn’t easy... I might change my mind if I can get an electric boot for it... but until then.

The starting does concern me, cranking my dads super rocket over with 8.25:1 pistons is harder than my A65 at over 10:1, but I did find even that got easier with time and practice. 

I agree Dave, it’s nice to have the legs at top end but I’d much prefer more tractable running and better economy. 95 with luggage and low comp pistons is a good output though. I was getting that solo before I fitted the higher compression pistons.

I would have thought the long stroke would have had a decent midrange (over and above a stock A65) for the same reasons as you I have fitted a touring cam (same as what we know as used on the A50’s but common placement on all late A10 and early A65) to the 823cc Thunderbolt motor. I’m not bothered about top speed, just want plenty of torque for 2-up with luggage

Thanks Allan.
I think I will set the 750 as it was so that I can reacquaint myself with how it ran and then be able to compare when making changes and probably try some new ideas on the 650 including C/R 2nd pinions in place of STD 3rd.
The most I ever got from my 650 was an indicated 95 mph.  That was loaded up with camping gear and sitting upright, low compression and it was incredibly smooth at that speed and sounded great.
Rather than top end I am more interested in low/mid range and economy.  With the speed limits abroad and the traffic at home there is little legal opportunity for ton plus riding.

Dave.
