Motad exhausts are normally numbered where the downpipes enter the silencer, saves a lot of head scratching! Also on your original problem IE running on three, check for bent valve on that cyl as i had similar problems with my 550.

Hi
Yes I contacted Motad and the stupid sales guy reckoned that they don't supply the head rings with their motad exhausts and to use the original Honda exhaust pipe collars! Despite my pointing out that the instruction manual he sent me says that the M6H comes supplied with 4 no. 21 head rings! He quoted me £7 for the bracket but when I said I would willing pay the £7 if I new how to order said item online from his website. I am still waiting to find out how I do this...
At least the instruction manual helped me to work out which pipe goes where. I would of been able to work it out if I offered it up to the bike but as the cylinder head and cylinders are off it at the moment I was kinda stabbing in the dark! Also I don't have the bracket either which I can see I will end up making myself.
Bad news on the honing is the engineering shop are no longer offering that service or rebores either anymore as it takes too much time for a relatively low return. But my local bike shop were able to point me towards a company in Wolverhampton that I can go to. The bike shop don't usually offer rebores and stuff anymore either as it is cheaper in the long run to throw the old cylinders away and fit new ones! I could not get my breath! Has this society really become such a throw away society that they don't bother trying to repair stuff anymore!
Gahh!!!!

Hi
On a separate note I have left the head standing upside down with some degreaser fluid in it. Unfortunately on Cyl 4 it has mostly leaked out through the valve seats after 4 hours so it looks like I can confirm that the valves may not be seating correctly on Cyl 4. Which may be the reason why it was not running on Cyl 4. But I am reserving judgement until I get the valves out and see what is going on for sure.
Cheers

Hi
Well I dropped of my cylinder block at PJ motorcycle engineering in the Hampton's (Wolvehampton LOL makes it sound posh). They wanted one of the pistons with new rings on it to make sure that the honing is correct.
I figured that I was only a few miles away from the Motad factory in Walsall. So I decided to visit and see if I could not order my exhaust collars and fixing kit including bracket. Fair play the guy was a lot more compus mentus in person and I soon secured required items and left a happy bunny!
My mate who is a bit of a dab hand at welding reckons he will be able to repair my old exhaust but it will need chroming again afterwards!
I will get there!
Cheers
John
