Hi All
Have now run the Norton at two rallies since getting it going, one over 6 days at Bathurst and two days at our Heart of the Hunter (NSW) in Australia this weekend, distance travelled around 750 miles.
Problems uncounted were
Too noisy
, small oil leak on one rocker spindle, lower gearbox bolt both nuts lost and stud damaged, also had uneasy weave at around 80 mph, kick starter rubbing on exhaust and hitting my leg. Power not so good until around 4000 to 4500 and then it is away, unfortunately definitely breaking the law at this speed.
Need to find better mufflers otherwise might lose hearing or be knocked off by other annoyed riders.
Fixed the oil leak, and gearbox bolt by replacing with the bolt out of my 1963 650SS project, pumped tyres up to, 34 front 36 PSI rear, no weave from there not at least 90 mph, purchased a new kick starter from RGM UK that gave more leverage and better exhaust clearance.
The bike was basically complete when I bought it but was in bad repair, work done was.
Purchased second hand cylinders as bores damaged and cylinder spigots damaged/missing beyond repair, second hand cylinders were bored oversize for 60 thou + pistons so had to purchase a set of EMRGO + 0.080 pistons and bore to suit, new cam followers fitted.
Head new valves, guides, valve stem oil seals, and valve springs.
Two missing fins below right hand spark plug replaced with fins cut from a Honda cylinder head and blended in.
Oil pressure was good 55PSI at 2000 rev/min and 25PSI at idle when hot so left the bottom end as is, although since running there are leaks in the case joints.
Fitted new vernier adjustable ISO mounts.
Rewired and fitted 200 watt alternator and electronic regulator, also fitted a new TRISPARK ignition (how easy was that), the original points, points plate and auto advance were missing.
Resleeved the master cylinder to 13mm and rebuilt the caliper, brakes are improving but most likely need a new disc.
The rear rim was rusted through so ordered a set of SS rims and spokes, only replaced the rear rim so far as the front was not so bad, and needed to have running for the rallies.
Carbies were totally worn out, I have never seen such wear in the slides and bore, so purchased a new set of AMAL Premium 32mm Concentrics, these have performed perfectly to date.
Rebuilt the front end using progressive springs, need to do more work here as they bottom out too easily.
These were the main issues, but as you would know there was a heap of other jobs to do over a 5 month period.
The rides, run in was for about 50 to 70 miles and then it was on, sort of without being over the top.
Handling, well with lower tyre pressures not so good, but once tyre pressures increased as good as one would expect from a 1972 Brit bike , I loved it, so easy to turn in compared to my ZX10, ZZ1100 and Suzuki GT750s, brakes not so good though :shock: .
