Hi Tom

I was thinking of the type shown below, but I guess if you've gone for oif forks there won't be a fixing point at the bottom near the spindle (axle):

Hi Tom

The bike's coming along nicely

. What's the plan for the front fender? The BSA / Triumph 3 hoop type would look good.

I hope the process to get the bike titled and registered is not too painful as I have heard it can be tricky for you guys across the pond.

Regards

No further updates at the moment. A couple of other 'projects' have got in the way. At least they are both BSA's

Hopefully get back on with the Typhoon next month

Hi Mike I guess you found the solution to the orientation of the shield? In case anyone else has the same issue here is the answer: Detailed examination of the sleeves (97-3672) will show that they are thicker one end, with a noticeable step on the inside. The thick end goes downwards, to cover the ...

Hi Terry

Pity, I have achieved an Oil tight BSA, never managed to do that

Last time I had a completely oil tight BSA was when it ran out of oil.

+1 what Kommando said

SteveS

Hey Gerry

I'm told its not how big it is, its how you use it

Looking forward to seeing how the Beast is coming along

I believe one of the CCM works riders had a nasty accident with a spark plug during a race, hence the addition of a guard. I can't find my copy of Rolling Thunder at the moment, I'm sure the details are in there somewhere

Hi Kommando

Unfortunately the hole is already cut to full depth. So if I go with the blue top decompressor I will follow your advice regarding sourcing and replacement

SteveS

Hi Kommando

Thanks for the warning regarding the blue top coming adrift. With the set up I have there would be damage unless I can think of a way of restricting the end of the opening.

Joe, when the bike's complete your welcome to have a look

SteveS

Hi Tom . I have to admit that I can do the basics with metal work but I rely on professionals for a lot of the more specialist work. . I am planning on fitting a compression release. The head I am using is twin plug and I was going to mount a release in one of the two positions. . I have a few choic...

Hi Beat

So your design has worked for a full season and you have identified just one problem. That's impressive

I'm sure you will find a solution to the hydraulics issue

SteveS

Hi Unable to help with the OTJ numbering system but good to hear reference to OTJ again. Before the arrival of the internet my only real source of engine details was my tattered BSA B50 parts book and the OTJ Bible i.e, the photocopied A4 booklet that Tony produced (probably with help from Olive (?)...

SteveS

Hi Beat From what I have seen from other welders work it would be grown in 'free air'. I guess it's a long and laborious task involving welding then filing and shaping, then welding, filing and shaping again, then keep repeating until full growth. I think we need more advice from people who have act...

SteveS

Hi Beat

I remember Stan commenting about fins but unable to trace the thread.

I know Mark can 'grow' new fins, maybe worth making contact to see how he does it:

SteveS

Looking good :thumb Just a word of warning.......... my mate used an extended front mudguard very similar to what you have fabricated. He had all sorts of problems with vibration causing the stays to break plus a split in the mudguard. He ended up trimming it back very close to the standard length (...

SteveS

Cheers Chris

I'll give it a go

Hi Any one got the correct crankshaft nut alternator side - 5/8 Cycle 20 tpi for a B50 71 (21-2066)? Not sure if it is plain or with a shoulder to locate against the rotor? N.B. parts book indicates thread is 5/8 unf but previous discussions have confirmed it is a cycle thread http://www.b50.org/php...

SteveS

Hi

As per his reply earlier in the thread Mark Cook lists the filter (60-2601) on his website, see orange button at top of page marked CCM-Britain. Unsurprisingly the price has gone up since he quoted in 2013

Hi

Somethings amiss. Maybe something has partially seized over time? I guess you have already checked the condition of the oil for any tell tale particles and checked the level is correct.

Hope the solution is straight forward

. I’ve been looking at sourcing a battery for my current project. I’m limited on space so have been considering going the lithium route. Most of the ready-made 12v lithium batteries still seem very expensive so thought about making up my own battery pack. . Requirement 12v, 12AH, small as possible ...

I've been busy making up more frame brackets, bosses, tabs etc. ready for my local friendly welder to work his magic!

Once these brackets are in place I can work out where the rear mudguard sits and then make up the battery tray support bracket

I didn't go as far as tapping out to 7/16", I just used a 3/8" bolt, one for each footrest, but I'm only a little fella

Managed to lace up the front wheel which has a Triumph Meriden disc hub. I will be fitting twin discs. Still need to centralise the rim but at least it's all together . Hu...

Thanks guys

I'll get busy on the lathe

Hi I believe the majority replace OEM specified bearings for wheel hubs with those that come with seals. Therefore apart from spacing everything correctly on the wheel spindle/axle is the any need to keep the grease retainers if all the grease is kept in the bearings by the seals? Could they be repl...

SteveS

. While waiting on some more welding to be completed I've been working on the rear wheel. To help with the wheel build I invested in a truing stand. I have been looking around at the various ones advertised and ended up purchasing the one here . It's fairly robust and will certainly be more than ad...

SteveS

Hi Tom

Yes, I will bear that in mind. Hopefully I will have a better idea of where any problem lies over the next few weeks.

Good point Gerry.

I'll drop in a pack of desiccant (silica gel) to keep things dry

Should just have enough room for a spark plug and feeler gauges

. Hi Gerry . Ignition will be fired from the regular location but as you say the points cover will be miles away. Since the 5 speed gearbox projects such a long way out I had to fabricate a couple of covers to get everything to line up. The final outer cover at the front acts as a small toolbox whi...
