I was too. The first time I needed to install one, I called and asked because I didn't want to fight another belt drive and I wasn't going to take the job if I had to take the cradle out - too much work for too little money. Matt assured me that he never used two and that he didn't recommend two. I've installed several and have never had the slightest trouble with anything.

The clutch basket is quite a bit wider than the belt, but it is the front pully that causes it to track so it aligns however needed on the clutch.

The Norvil one that I fought was running against the inner chaincase and shredding and when I would get it to stop that, it would run against the guard on the outer of the pully and shred there. Two adjusters would have been better/easier, but even then it would still have been tough to dial it in perfectly and I have no idea how long it would last.
When fitted my norvil belt I made an Extra adjuster for the drive side it only took minutes to setup with two adjusters
It's been on there over 20 years
I did put a new belt on just before I fitted the Alton
Not that it needed it but the belt was old
When I fitted the Alton I faced the adjuster the opposite way to make it easier to adjust
 
Greg’s comment “Besides VAT, the killer is shipping. It's a big, heavy box” Made me wonder what the additional weight of each is after fitment. My guess is the CNW adds the most? But it would be interesting to know.
We used a hanging scale to weigh an Alton equipped 71 750 Interstate with a full tank of fuel and my 75 Mk3 Interstate with full tank. The difference was about 5 lbs, the MK3 at 477 and the the 750 at 472. So negligle difference, although that 5 lbs is and important 5 lbs in that it is due to strengthened items like swing arm, crank, cases etc.
On the same scale we also weighed a 1971 kickstart 750 Interstate and and a 1973 Kickstart 850 Interstate, both bikes full of fuel as well.
Those were at 443 lbs and 447 lbs.
That four pound difference there is again expected with the strengthened items, of which the early 850 has a bit less of than the MK3, one pound worth according to my measuring.
So the estart MK3 or Alton adds about 30 pounds to the bike.
I haven't weighed a CNW equipped bike.
The starter weight is all low down so as a regular road rider you won't even be able to notice that it is there.
I have ridden with a single pannier loaded at about 30 pounds. This was a lopsided load and higher up than the starter. It had no noticeable effect on handling or corner speed. It also isn't noticeable for acceleration.
The extra 30 lbs adds only about 1/10 of a second to dragstrip et, so no wonder we don't feel that bit of weight.
The one time you might feel it is rolling the bike up on a lift or something like that.

I have experience only with the Alton, which this bike came equipped with. It has been flawless so far. I have had the assembly removed a few times for other servicing and it is a simple process, which I like. I vote for the Alton. I just hope they are still around when the time comes for parts.

Don't forget the battery weight, if it is shipped with the e-start kit...
I installed Shorai LI batteries in both the cNw and Alton installs I have done. In both cases significantly lighter than the standard batteries I removed. As in multiple pounds. With the cNw starter there has been no question that this robust starter can spin the motor easily for a long time. It felt like the Alton starter hesitated a bit against compression in a stock 850 w/150lbs compression.
I obtained an unmolested Mk3 with 1800 original miles some years back. The not - original battery it came with started it ok until it died from fatigue, but when I installed a Shorai it started immediately and easily every time.
Each bike with TriSpark ignition. I was a fool and sold that one with 5,000 miles on it. I liked it best of all electric starts. The cNw starter is big and a bit clunky looking and requires attention to oil line plumbing. Ham can airbox won’t fit. Alton is svelt and fits nicely with a stock bike like it belongs there. But the electrical junk hanging off the battery seems weird. I would much prefer a stock Lucas alternator and rotor.
A Mark 3 is, well, a Mark 3. Very nice and worthy of the cNw upgrade
 
Well, there is a clear favorite / best-seller / best aftermarket e-starter for the pre-'75 Commando, and that is the Colorado Norton Works package. Regardless of how accurate the percentages are, it's a pretty clear comparison.
 
according to this page, import duty is 2% (that seems low to me) and then VAT is 20%, so that would bring the price up to £3013. Shipping and handling have gone through the roof since Covid so that's anybody's guess.


I recently imported a cNw kit from HollandNortonWorks and paid 2% duty and 20% vat, which exactly matched the info on gov.uk. ParcelForce added £25, which was less than I'd expected. HNW charged me €45 postage for the kit + some other stuff including their X-ring chain conversion, kegler clamps etc. Constant Trossèl from HNW was great to deal with, and they charged €3190 for the kit. Overall, I was very happy with the transaction, but ParcelForce/HMRC took weeks to clear the package, but that could happen wherever you buy it.
 
I wanted to share my final thoughts on comparing Alton with CNW. I have the Alton and am happy with it.

I did contact the Alton factory and ask how many Electric Start kits thay have sold total for all makes.
I wanted to know if they were going to be around to support the product. They replied that they had sold over 2500 Electric start kits. While CNW is a much lower volume manufacturer, their product is beautifully machined.

I also contacted CNW to ask about kickback protection (as Alton has the dowels that shear on kickback) and they replied there was no kickback protection.

For me, both CNW and Alton are fine products. In making my decision to buy Alton, I liked that they had a huge installed base and that this had given them experience to enhance their product over time (I read very old threads with problems early users had). In addition, it was clear that Alton will be here in the future and are responsive with technical support and parts.

When I installed my Alton, I did have a technical problem. The new Alton inner primary cover seal that covered the transmission output shaft, was the wrong size. Paul at Alton responded quickly, accepted that the fault was the factory's and quickly sent out new parts.
