Well, I'm just about to click over 10,000 miles since the resto was completed in March, 2016. A few observations so far.

Very few issues so far. A wonky back wheel which chopped out the wheel bearings before it was found that one of the spacers was short. How? Don't know, but bike has been handling beautifully since the fix.

I am going to stick my neck out (as usual. It's become a habit) and say that this is the finest handling Commando I have ever ridden, by far. The recipe goes like this,
Vernier isolastics from AN
Lansdowne conversion to front forks.
Basic Ikon shocks on the rear.
Jim Comstock/cNw head steady.
WM4 (2.5 inch) x 19 inch Morad alloy rims with Avon Roadrider 100/90 x 19 tyres.

I cannot get over how well this bike handles. It tracks absolutely true yet is so light in the steering. I have never heard the phrase "handles like it's on rails" applied to a Commando. I have now and not by me. I just returned from a 1500 km trip from my home in Perth, down to Margaret river in the South West of Western Australia and then across to Albany on the south coast and then back to Perth via Albany Highway. The roads across the bottom of the state are quite rough and ready, but are absolutely beautiful with almost no traffic. However I thought the bike was going to handle this trip,I was not prepared for the sure footedness and comfort over the rough stuff. Going binto the higher speed stuff at er...a little over the speed limit saw it handle the bumps beautifully, never moving off line and with the bike remaining absolutely stable, yet so light to the touch. I was amazed. The only casualty of the trip was a torn rubber manifold on the Mikuni which allowed a little lean running. So, I lifted the needle a notch until I could get home and fit a replacement.

The engine is an absolute delight. Pickup from highway speeds for overtaking is outstanding. Power everywhere that I want to take it which is almost never over 5000rpm because I've never needed to. The engine is basically standard with a PW3 cam, conical valve springs via Jim Comstock and various coatings applied internally. No power steps, with grunt from absolutely off idle. The engine builder, Ben from British Imports here in Perth has built and ridden plenty of Commando engines over the years with many fancied bits and pieces and this is his favourite.

It is the best and most satisfying motorcycle I have ever owned or ridden. That's the way I see it and I've owned and ridden a lot.

That's great to hear. I have some of the set up you describe; less the head steady, carbs and your fullauto head.
(wish that I had one) :wink: My headsteady is a Dave Taylor type and carbs are re-sleeved original Amals. WM4's on AM26 Avon's. My cam is a Mega Cycle. I am using the Ikon rear suspension set but I have placed an order to rebuild the bushings. I have more than 10,000 on my rebuild. I had a small oil leak that sprayed my gearbox and ham can filter. turned out to be just a loose oil pressure valve. Its good now. I like the cNw engine bolt kit for head and cases. Jim C makes a good breather valve and timing chain tensioner. All Good mods.
Keep on keepin on.
Cheers,
Thomas
 
Must be the travelling time of year, just back from a 3000 mile round trip to our annual (NZ) rally.
First long trip for some time on the Commando and also loved it.
In my case a full auto head, PW3 cam, Keihin FCR's but rather tired standard suspension, the rear in particular felt undersprung and underdamped with luggage on.
I also run a 90/90 front tyre and think that is a great improvement.
And the Alton starter was great for me, i have a knee which wouldn't allow that trip on a kick start machine.
 
Sounds good Ken.

Two questions if I may:

1: when are you going to fit and test and report back on the a CR carbs?

2: When are you going to fit a front mudguard ??
 
First thing I thought when I saw the photo was "not in the UK would the front
go naked for long!"

...and wot chain guard do you have on it?

1. Don't know that I will Nigel. I'm extremely satisfied with the performance.
2, Next week.

2. cNw. Lovely early style.
 
When it is handling as well as you say, are you carrying any weight luggage wise and how much do you weigh? If you don't mind me asking.

Traveling light. Just a bag over the shoulder. 115 kg.
 
I weigh about 76kg, probably just over 80kg with riding gear. I think this has a lot to do with Commandos getting a bit flighty on long straight roads. They need a bit of weight to pin everything down.

They're going to be flighty no matter what you weigh. I know what this bike was like before the mods and there is no comparison. This is how Commandos should handle.
 
Hi Ken,
Are you able to rate the five individual ingredients in your recipe in order of greatest improvement to handling?

Thanks,
Ed

Sure.
2.5 inch rims. Avon Roadriders. Unbelievable difference to handling. Light, precise.
Jim Comstock head steady. A noticeable difference in control. More planted feel.
Lansdowne conversion, tames the front end with comfort and precision.
Ikon shocks, comfort, controlled rear end at all times. You never even think about it.
Vernier isolastics, a no brainer. Just makes life easier.

The mods were done over time and separately so had a chance to evaluate the changes.

1. If you're extremely satisfied now - then how would you feel with the CRS carbs? Ecstatic?
2. Ft fenders may keep the mud off your face but they hold down your wheelies.
 
"The engine is an absolute delight. Pickup from highway speeds for overtaking is outstanding"

What rpm are you doing at 60 mph?
 
Interestingly, my Fastback has WM2 front and WM3 rear and 19 inch road riders, Koni rear shocks, rose joint head steady, vernier isolastics and Landsdown forks. Apart from the width of the rims and the rake angle (being a 1970 model) very similar spec. Hacking round the Welsh countryside is no problem but there is still a sniff of a weave at above 75mph on the straight. Probably down to my weight and rake angle I guess.
 
When I move my feet from the rider footpegs ( standard) back to the passenger pegs, the weight shift causes the bike to go into a slow weave at 75 MPH and up. It's harmless enough, but not enjoyable so I don't put my feet back there anymore. It made me realize that rearsets would not be a good plan for this bike.
I've also wondered how many of the reported high speed weaves are on bikes with rearsets.


This bike is rock solid to 110mph with feet on the rider pegs, standard position. 225 lb rider, MK3. 850
