British Bikes / Re: Norton Lockheed Caliper Problem

I've probably missed something here, but why are you pumping air into the caliper?
Are you back bleeding, ie forcing fluid through an open bleed nipple? if so leakage past the threads can happen and shouldn't be a problem providing the nipple seals once closed.

Chris,
RGM sell a check valve, but first try the pistons on top dead before laying the Norton up, it sometimes helps.

Hi Chris,
Is that photo taken at Holka Hall Museum? sure looks like Tommy's van in the background. If it is, there's a lot of folk in Cumbria will help you.

British Bikes / Unit to pre-unit Triumph
« on: September 28, 2006, 03:42:35 PM »
 Hi all,
I have a set of good lateTriumph 650 pre-unit crank cases, rods and an iffy crank. What unit parts could I use to build this motor?
Cheers.

Before pulling the carbs to bits try a new pair of plugs, if that works and if the problem returns try a hotter pair or try advancing your ignition. Could be dry fouling. (crap modern petrol with funny aditives) There is a reason why the choke helps but I forgotten why.

With a Goldie on full chat I wouldn't worry about your flares more your leg.
Don't forget Jets are cheaper than a mag rebuild, fingers crossed the mag's ok.
Best of luck on your track day,
Dave

Nigle,
If the problem is with the carb and I think it is, its the main jet only. Try a size down and see what happens, If its worse go up two sizes.
What type of inlet are you using,  filter or bell mouth if its a bell mouth has it a mesh?

Nigel,
What throttle opening does the misfire start?

I'm think the mudguard may have come from a Royal Enfield Clipper. It would have been unsprung and not fitted to the fork sliders.

I'm pretty sure the advance unit is BTH

British Bikes / Re: 1933 Model 18 Norton
« on: May 27, 2006, 03:28:37 PM »
Taken from the book "Motor Cycle Maintenance and Repair" all Norton models from 1932 by Norton's EM Franks.
1932 Model 18.
comp 6.2:1
Ign 5/8"  BTDC fully advanced
valve inlet timing opens BTDC 1/4"
exhaust closes ATDC 1/4"
tappets cold inlet 0.002" ex 0.004"
piston ring gap comp 0.020" scraper0.008"
plug lodge H.1

Models 50 and 55 with 7:1 compression also use the lodge H.1
I've lost the equivelants page from "Speed and how to obtain it"third edition, but the author mentions fitting a threaded adaptor to fit better racing plugs.

For 1937 SV and OHV models Franks quotes the KLG F100 and Lodge HHN both 14mm for OHV. Sidevales KLG M80 and Lodge H3 both 18mm.
I hope this is of some help.

I agree with L.A.B. but make sure you get hold of the best strobe money can buy guaranteed for an instant flash ie no time loss at 5,000 rpm. If you can't you'll end up advanced, it would be better to stay with the Boyer static timing.
