:? Hi
This is my first post here, but with the recent purchase of a 69 Commando, it won't be the last. This is my first Norton, I have had Triumphs in the past, so I've tried to read up and get smart on Nortons but it seems that the more I research and read, the more confusing some things become. Therefore I'd like to ask for recommendations from people who actually know something about them.
The bike is a 69 with a little over 3200 mi on the clock, pretty much all there and not in too bad a condition (I think). The engine is stamped 20M3S/1330xx. Does this indicate a model? I was told that the bike may have been an S model (I guess those are the ones with the scrambler type high mount exhaust). As it no longer really has an exhaust system(and no sign of mounts) I can't tell. Perhaps if it was an S that would explain the Dunlop K70s on both ends and the little grill around the headlight. As I said it really doesn't have an exhaust so that's where I need to start, and I need the whole system including the nuts on the head. I plan to use it for road work, mainly spirited solo touring so I would like to get the best performance (read least restriction) from it, but I would also like an easy fit with the standard kick lever, etc.. I have seen replacement S model systems and would consider that but would like to know what the advantages/disadvantages are as the price a bit higher. I noted quite a discussion in a recent thread about problems with kick starts hitting the mufflers and would like to avoid that sort of thing. What I would really like is recommendations on specific systems (brands) that would meet my needs for fit and performance. Is it necessary to buy a complete set from one manufacturer or is it possible to mix pipes, mufflers, mounts, nuts? Also, I have read differing ideas on the exhaust nuts, like using newer 850 nuts for more security. What is the preferred setup here ?
The carbs seem to be in reasonable working order (the least worn set of Amals I've seen) and after a good cleaning internally, I will continue to use them. The set up is: mains, 320; needle jets, 106; needles, 2 groove using top notch for clip; and #3 slide. It does not appear that anyone has changed them but I am unsure what the factory specs were.
There are obviously other things to check, renew or replace, like the tires, but I'd like to get the exhaust fixed first, so I would appreciate all comments on what to get. Thank you again for your input.
Cheers
