Road Racing a Norton Commando

By far my tool of choice for power loads into turns is iso's with robust rear link + 2 compliant helpers as any and every bike can get it on after apexes. My quandary of: lf linkages about as solid as a Seeley or Asian bikes was any significant gain over full solids was solved recently by Doug's upgraded video, to see there are a handful of clustered up close race starts,... every time they encounter some real turning to tackle. Riding a corner marking cone is not my hobby, riding around em is while feeling nothing but the thrill and wrist strain. There may be a premium on old Commando frames to link right someday. One down side though is mileage suffers w/o as much throttling down going around.
 
Thanks Dances, have been on the cradle and swing arm most of today, am looking at inserting a tube and long bolt where the old centre stand holes were.
Probably weld the tube in place and mount a heim joint in there somewhere, back to the frame.
Have already installed the tube collar upgrade (Zegler/Hegler?)and big tack welded the back half (inside half) of the shaft collars so no fiddling about when do a fit up.
Spindle is as tight as possible drifted in through the swingarm bushes with heavy plastic mallet. Checked for roundness and emery honed after welding.
Looking at plating across the cradle above the swingarm and below the ISO tube as well.
Regards Mike
 
@Brooking 850. Actually faced with doing the same thing with my old Commando road racer which has set idle for more than a decade. Since I had tossed the bike a few times I had a local frame builder http://www.framecrafters.net assess the frame for straightness and geometry so I will be coming from a known.

Plans include a Herb Becker stock stroke engine which is sitting in a crate, tuned exhaust to make the motor happy and stabilizing the head and below the transmission (similar to what Herb Becker did for Doug McRae's bike). I think Doug McRae actually ran this motor a few times while his original was being "freshened up".

Herb also mentioned changing the combination and number of rubber doughnuts inside the ISO tubes. I don't know if Doug McRae elaborated on that detail but I will be checking with Herb on this. I can tell you that the Commando that Herb let me race a few years ago was literally a magic carpet ride; even when compared to my old Commando racer. With the geometery and set up it was scary for me at first because it would so readily drop into a turn; but it would hold the line.

Just be cognizant of the expected arc the heim joint rod can form as you should avoid putting the ISO thrust surfaces in a bind.

Good luck with the build.
 
ThANKS DANCES, KEEP ME POSTED ON THE EXTRA DONUGHT info from Herb(damn caps lock) and any chance of some pics of your rear heim joint? Nothing personal intended here!!!!
Regards Mike
 
Frame mods should not cost much as long as you carefully plan what you are going to do, and think about loads, flex and play etc. What will cost money is if you decide the work has been futile, and you then want to buy one of the trick frames. If youve already got a complete commando, it shouldn't cost much to make a racer out of it, until you get ambitious. When I built the Seeley I didn't care much about performance - just built it to best practice from past experience - it just happens to be fast and handles really well. Except for the gearbox, there isn't anything on it that you would call a performance part.
I'd also be interested to see your frame mods when you've finished them.
 
Road racing on tracks is very safe compared to riding on the street. I have been lucky enough to have had only one high side in my career. Low sides are usually pretty harmless on tracks, just a little wear on the leather. Have had plenty of them.
 
I have a strange view of what is 'safe '. My definition of the term is 'a situation or condition where the risks are minimised to a level which is tolerable to all stakeholders'. In other words if your family cannot stand you racing - don't do it. It is all about competence and attention to detail - to do it properly, you probably need to be compulsive/obsessive, and have no ego. That is not me, and probably the reason I never achieved much in the sport.
 
Low &-or High sides lurk at the limits of all normal handling motorcycles. Its funner-safer if those upsetting behaviors can be added to normal flight envelope.
 
The important thing is to know where they are. If you never go there, you don't find the limits. The main thing is to work up to them slowly, so you always recover from the situations.
 
Prevokeing them prematurely while away back from the obstacles can give a indication , if it doesnt hinge and lauch you into the scenary .
 
I missed out on road racing and used to wonder if I had the right stuff for it, beyond just a desire. I did other things for many reasons but if I'd know about vintage racing things might of worked out differently.

Learning limits is touchy business as well as looking out for others. I know how close to the edge anyone is when in racing moode so it ain't just you to think about taking out. I used to think that if ya just followed someone else and took their lines your bike could too, NOT SO!!! Also following someone vs leading the pack is extra adrenalin thrill to control. I found that someone else's lines may collide with yours so can't always pick best line for your bike. Like aiming into crash ahead so they ain't there when you are, may have to aim away form crash that may lose your place over.

One firm rule on of mine on public roads is never ride to get scared but to find bike limits or ways around it, you do have to cross fear barriers or don't expect to be very competitive. Riding fast is its own reward going out on track but racers are there to win so pressure is on and being scared of your bike ain't fun nor safe.

In a lot of ways going race fast is easier to work out basic limits. How far to lean til fouling, at that point how much power to break free somewhat, then at those two limits how sharp can forks turn. Ballistics give some grace and time to recover or explore further, on next pass. After that the lessor turns are a relief.

Braking is the hardest part and I've learn hard way don't expect much of brakes while leaned so best wishes learning to slow enough staying in control anyway ya can.

I wonder where I'd find a crew and bike hauler and maybe a sponsor with cool decals.
