... because when we fitted it to the 500cc Hima while also exchanging the cam chain it was found that the bolts holding the 2nd layer (the one allowing the adjustment) would hit the engine wall - they simply have too big a head.
Funny that the guy who made them never found that out, seems like an easy thing to fix if you know about it, just use flat headed bolts.

In any case, the guy we get them from promised to find those bolts and provide them for us. When this happens we will continue to sell the sprocket.
For the very few who already purchased it we will send you the correct bolt if you request it or you can find them in a local hardware store, should be easy enough.

here you can see when the cam lock is placed the bolt will not slide by the engine body anymore but hit the edge. The solution is a bolt with a flat head.

If you get you own bolts in the meantime, be sure to look for High Tensile hex head black bolts.
They should be marked "12.9" preferably or higher is okay.
Also the 3 5mm bolts should be loctited.
 
There is a jerk active in the "Royal Enfield Owner's Forum" and I am not talking about Eatmoremud - who I would call a super jerk (he dissed me for publishing negative facts about the Himalayan, e.g. the broken frames - and continued to tell lies about HT and our products AFTER I was unable to respond because be had blocked me) .
No, I am talking about a jerk called Tom_d who, without any knowledge of the background or details of our products, he never asked too, tells hyperbolic stories about how bad we are and how we never test our products - He must be one of those people who define themselves by finding the fly in the soup of anybody but himself - poor soul.
But to clarify for those who read here and also in the REOF: we have sold ONE of these sprockets and given away ONE for free - so a total of TWO got to customers before I had the chance to test this product on my own Himalayan. Our supplier should have tested it but - alas - we also have a responsibility to check. that is true.
Now: was any damage done - not that I know of - did the ONE customer who actually paid for it request a refund (which he would have gotten)? NO. Why not? Well, the flaw seems not too hard to fix. Nonetheless, we will not sell this item anymore. It was a good idea but badly executed.

I am of the opinion that we did as well as could be expected given the size of our company, the complexity of the task (disassembling half the engine). I believe that the bad mouthing of HT at the REOF which certainly has a tradition there, not the least because the MudEater is always the first to "like" any nonsense sprouted there about us, is partly balanced by some of our customers who try to give a wider perspective to the issues (or rather none issues) mentioned there. And I am thankful for that to be sure. But on the other hand: people who believe any b/s they read on the internet without doing their own research as a rule deserve to live with the brain fog monkeys like Tom_d sprout.
 
Hello
How is the adjustable cam sprocket used?

I received it in a similar position to an original sprocket.
In what way should we touch the 3 adjustment screws and to do what? How many graduations should we modify?

sorry, but I'm a little lost on how to use it

Set the crank at the mark before the T,
Make sure you are looking directly down the inspection hole!
Then set the sprocket with the marks so it lines up with the case, tension the chain and then with a pair of pliers rotate the Cam to the correct position ( using the line at the end of the Cam get that in line with the gasket face) then lock up the 3 bolts using Loctite.
 
Dool, thank you for this information. (y):)
So the adjustment consists in adjusting the sprocket marks so that they are exactly in line with the joint plane.
This is to avoid any minor offsets?
 
Yes after setting TDC you now have the ability to get the Cam in the correct position before locking it up.
Otherwise you find( with the OEM sprocket) the cam marks never l8ne up properly because the chain sets it either back or forward of the marks.
 
Thanks for this information Dool.

I just wanted to add that the adjustable sprocket does not fit well on the camshaft. The small hole is too tight which means that the sprocket does not fit well on the cam.

I did a little drilling with a 5mm drill bit and then readjusted it with a dremel so that it fit perfectly.

I checked that the screws and the half moon allow the sprocket to be attached to the cam. It's OK.

Hey, the 5mm hole, are your talking about the "Dowel"?
If so the dowel is NOT to be used as it will prevent adjustment.
 
yes I'm talking about the dowel. In the photo it is the part circled in red.
On the original sprocket it fits well on the cam shaft. But on the adjustable sprocket it didn't fit well.
But how not to use the dowel? It is fixed on the camshaft.

Sorry was thinking about my version of the adjustable sprocket.
Dowel can be removed, the first lot of Tec Cams came without the dowel and it was retrieved from the old Cam, its a bit of a delicate operation using a pin punch and hammer.
With an adjustable sprocket the Dowel is obsolete.
Be sure to use Loctite on the Bolts.
