Re: 1962 Arrow Starting Problems

The compression does seem to be low but I've had a bike with similar compression after a re-ring and it started OK and the compression eventually increased to a normal level. ( on one engine I used Aspen fuel after a rebuild and it started more easily than normal ) The primary compression ( crankcas...

Re: LEADER RIMS AND TYRES

There may not be enough clearance between the tyres and mudguards , you might find there is just enough clearance The gearing will be too high in top gear ie. the engine will struggle to pull in 4th. The centre stand may need to be len...

Re: A question on ignition timing methods

Re the timing on the engine. When the Standard Leader had points ignition the bike ran well and started well after spending time getting the timing exactly as the workshop manual recommended. On the 270 Leader with Pazon I set the timing as per the instructions to get the engine going and then using...

Re: 1962 Arrow Starting Problems

Hello John,, To answer your question from the first message. The compression pressure is normally well over 100 psi for the Leader/Arrow engine and after a rebore it will be less until the rings bed in properly. Is the fuel getting through to the carb, the reason I ask is because I've just repaired ...

Re: 1962 Arrow Starting Problems

Hello John, I've just checked an engine casting and there is a hole which collects oil from the near-side cylinder ( at the bottom of the transfer port ) and comes out into the spaced between the centre bearing and double oil seal. The drilled hole does just break into the centre bearing recess but ...

Re: Arrow Front Brake

Hi Roger, There are others who offer brake lining - Villiers Services in the West Midlands and Friction Services in the Bristol area. I bought some relined shoes from Keith Harding at the Stafford Show a couple of weeks ago, I think he still has some left. Most of my brakes have had standard thickne...

Re: Arrow Front Brake

Hello Roger, The brakes are nominally 6'' diameter and if they have not been skimmed will be within normal machining tolerances of that measurement. I've have most of my brakes done/relined by Classic Brake Services of Whalley Bridge, using rivets to secure the linings. The linings are black with an...
