IMHO it is technically better for the reasons I stated. it is NOT in an over run state with a sprag clutch that is a KNOWN weakness with the 850 MK3 and unproven in LONG term use on the Alton. the Alton also has a lower watt output alternator than is available so another draw back. without seeing torque to the crank shaft numbers from either one from all appearances the Alton MIGHT be the looser on this point but that is just a guess on my part. yes it is more expensive and you do loose the OE look's with an after market air filter.

Old Britts or QPD better than Alton in what way?
Technically? : questionable!
Price? : certainly not!
Looks? : certainly not!
IMHO Alton is favourite.
I don't think the issue with the MK 3 is that it is a sprag, it is that it is a very small sprag. The Alton sprag is far larger. A poorly built bridge may collapse, and we all know that has happened. The issue was not that it was a bridge, but rather that it was poorly built. Similarly, an undersized sprag may well not last long, but one that has the correct specifications for the work it has to do will function long and well. It is not as if only a Norton and a few other other devices use a sprag. There are thousands upon thousands of variations, and millions upon millions of applications.
I am happy to be distributing the Alton kit for several reasons.
One is certainly the quality of the parts. Some have mentioned fitment issues with non stock installations. I think it is totally acceptable for some modifications to be required when installing with different belt drives, or crankcases and the likes. It speaks volumes for the quality of the kit that you can easily adapt it for reliable use with a wide range of other components.
And PRICE!!
Some say, "that's a lot of money". Except it is not.
Very few previously could afford an electric starter, because it was a lot of money, and installation was drawn out and complicated, without the possibility of an easy reversal.
I am currently offering the kit for $2250 AUD delivered anywhere in mainland Australia. I have been around motorcycles for a good few years, and that is one of the best value parts I have ever seen. I am not saying that as I am selling them, but rather that's a major reason why I wanted to sell them.
Alton back-up.
They stand behind their product.
And they are currently working on other kits, for instance a cure for the mk 3 ills is well underway.
I do think the eStarter Kit is a great product, and at a very affordable price point.
That's what got me on board!
I have raised the issue of a timing mark with Alton, and to be fair it is not that difficult to paint a little line on the alternator. Keyway is at 12 o'clock, after all. But it would be nice if the line was already there, and that is the point I have made.
