:biggrin: ha ha .... just finished building my refurbished Mk1.... went and did a 10 mile tt this evening on it.... oh woe is me, anyone got a 12 tooth sprocket they can lend me :wahhey:, 53x14 just ain't high enough.... top gear all the way round and and spinning furiously on the down hills, 29.50 ,, oh dear,,, 71 year old Bill beat me by a minute tonight:wacko::biggrin:

I can see why folk used a 60 tooth ring on them.

I am about to send my entry in for the Welsh 12 hour tt if anyone else fancies giving it a bash :biggrin:



Will post some pics shortly, too late now as it getting dark.

blimey.. using Sheldon's gear calculator...

my gearing with 53x15 as I have just counted the teeth on the sprocket.. @ 100 rpm I would be doing 19.5 mph.... no wonder I struggled to get evens tonight, top gear was a lovely 65.6 inches. That is low in anyones book...

I have to get a 12 sprocket to give me 61-71-82 inches with an AM hub, this means that 2nd gear which is direct drive and most efficient will be about right I think. 100 rpm = 21.1 mph, sounds about right.
None of our tt courses [ apart from the hilly ] has anything I cannot manage to get up easily on a 66 inch gear so 61 low should be ok..

ha ha.. I have the rattliest AM in Christendom :smile: some thicker oil has helped but it is still noisy... any advice hubgearfreak or is it just a bit knackered? Sounds like a tin of rusty screws being shaken vigorously when coasting:wacko:

My FW was pretty rattling before 1st gear stripped itself...

Do you like the quick release split pin device?

I was really pleased with the re etching job, nice touch we thought..I have to get some transfers made up, not bothering with Moulton transfers though, I just want one saying "Skippy"... that's because it came off a skip and boings about a bit:smile:

I have ordered a 13 sprocket and will try and knock up a 12 out of an old cassette sprocket, wheres my grinder?

sadly, not really.

you've probably already read these workshop pages. i have made hubs that don't work, work, if i read the instructions on reassembly carefully, and work through them with all the bits cleaned well. the planets need aligning in the AM, but you know that too?:blush:

other than that, it'd be worth contacting derek at http://oldbiketrader.co.uk he's got the best range of spares and the best knowledge.

It is as I bought it... All I have done is transfer it to another shell so timing the cogs should not be necessary, I think it is just worn out. Could check it I suppose.. oily hands.... again ....

If it isn't timed properly it sticks a bit if I remember..

Good to see Derek is up and running, his site was out of action the other day, I bought a recon FW off him recently, and very good it is too :blush:

I see he has a AM internal unit for sale at the moment.. tempting..
