Series 2

Extractors let the exhaust gases flow better . With SU's they can be a problem off road as when the vehicle is on angle the fuel can be too high or too low in the jet causing them to folld or starve for fuel.

Thanks.
got some numbers off the 15 inch wheels.

Extractors are well made.
Home job ????
Also front diff protection plate. Have to look for repaired crack.

yellow on guard, which appear on the front bits.
None on seat box and rear tub.
Plus pics of the SU carby, using original throttle linkages.
effort has gone in to get the float bowl upright.
Plate on guard, with 4 factory type rivets, suggest exhaust exit ????

1. The reinforcing on the axle housing was optional, but seems to be fitted to almost all Series 2 109 and all Series 2a on.

2. The early 2.25 engine had a manifold that had the exhaust exit up and out, and the pipe probably originally went out there. This may have originally been the case, or even if originally fitted with a down exit manifold, and the guard was patched in manufacture.

Will take a pic of the key, which was cut and the spare.
6 digit phone no.
last 6 numbers of this company.

Locksmith Townsville - Norm Hyatt Locksmiths 24/7 call out.

According to Google 6 digit numbers were between 1960-71. Original 67 cut spare maybe ????

I was just wondering why, with the claimed improvements the SU carby makes to throttle response and fuel economy, and its simplicity,
Why don't more series owners convert to them ????
what are the benefits of using extractors, instead of normal exhaust system.
Thanks.

Shane I only came across this adaptor for an SU type carby yesterday, so obviously there still are people fitting them to two and a quarters.
Adaptor is designed to accept (1.75") SU HS6 & HIFF 44 Carburettors.

As for the extractors, should be increased performance, maybe improved economy, probably more noise in cab.

Cheers, Mick.

And less flexible driving - the extractors work best at one specific rpm where the pulse from one cylinder results in a pressure reduction for the next cylinder to fire. This happens at one rpm, and the extractors are usually designed for this to occur at maximum power rpm to up maximum power.

Thanks Gents.
Love learning about these machines.
Good new about the diff guard.
So, why do the 15inch and 16 inch rims have the same part number ???? Took the Tape to them tonite.
Looked for a gearbox numbers. have to do a bit more crud sanding.
Guess I should be spending time on Gilbert (S3)
