How many AJS 33 were built?.
How many AJS 33 were built?.
Not many, but why do you ask? Do you own one?
Hi Knut.According to the 1965 Spares List Supplement your forks should be like the 1964-66 G12 & G15 Roadster (i.e., 030037 Damper tube, NM18813 main spring) except gaiters (accordion), short cover tubes and clips replaced the long covers (clips are not listed, actually). Hope this helps.
Interested to hear about your difficulties, Andy. I have the Matchless variant, and have been working on a longterm process of a 33 replica, just because I think they're cool. Thanks!I'm half way through a rebuild of a genuine 33csr , i thought my p11 was hard to restore but the 33 is proving very troublesome .
As far as I know, the AJS was only available as the 33 and the 33CSR. The 33 was the same spec as the Matchless G15mkII, and the CSR was sold as the G15CSR, 33CSR, and Atlas 750 SS ('66/'67). The CS was sold as the Matchless Scrambler and the Norton Scrambler. These hybrids, and the P11s, all came with the Atlas 750 with the dished pistons and a 7.5/1 C/R. According to the NOC, about 5000 of the G15/N15/33 hybrids were built between 1963-68 (and 3 one-offs over a year later for a dealer in Europe).
Also, the 1958 Norton Nomad had the designation N15. 1959 was the P15, and 1960, R15. This was a 600cc desert sled in a Model 77 (non-featherbed) frame. I think around 300 Nomads were built in 1958-60, with a small number of 500cc variants also produced (maybe 40). Some of the N15 registrations may be this early model.
All of the Nomads and N15CS/G15CS were export-only, but some have found their way back to England (forbidden fruit)
My bike <...> has the large ribbed fenders and seat and exhaust system like the G15 MK2.
The front fender has the correct bridge not like the G15 MK2. The rear fender has the correct long chromed upper stays, not the black short like G15 MK2.
Could you post a photo of your bike? There are several possibilities why your bike looks the way it does. It's anybody's guess. A previous owner may have fitted Mk2 and G12CSR parts due to a collision, or in an attempt to combat mudguards from cracking. I assume your frame number is genuin no e? The factory certainly didn't build 1965-67 M33CSR's like this.
If the front fender has the narrow type bridge, this points to a "homemade" conversion. There is a reason why the factory fitted two Y-stays for the Mk2 and M33 /export model rather than a U bridge with the big ribbed fender.
As far the rear fender goes, the short support tubes and grab handles 029440/41 was a poor decision by AMC for the G15 Mk2 and M33, which led to rapid fractures at the fixing points. You say the rear fender has the correct long chromed upper stays. However, the CSR came with a closed loop and a C-section alloy mudguard, equally susceptible to cracking.
The long chromed handles NM22634A together along with the chromed ribbed mudguard was standard fitment on the G12CSR. Thus, I believe a previous owner changed the rear mudguard along with the support tubes/grab handles of this bike into parts off the G12CSR, maybe off a wrecked bike. In my opinion, these look and work far better. It's a mystery why AMC offered these two bikes (the G12CSR and the G15CSR) with different cycle parts, but the ribbed steel fender theme seems to have been a mantra back then and it does provide far better lateral stiffness than a non-ribbed alloy fender. The non-chair version of the Mk2 (G15 Mk2 /home and /P) had black ribbed fenders front and rear, the front fender being identical with the G12 standard model.
029522 was a rear mudguard developed in 1962 for the 1963 model year to suit all roadsters including the G12 STD and the G15 Mk2 (either chromed or black). While it works well on the singles and maybe on the G12, it doesn't work well at all on the G15, as noted.
The G12CSR rear mudguard carries p/n 030194, which indicates it was designed in 1963 for the 1964 model year. It is less valenced than the previous one and I guess it was designed primarily to market the G12CSR as a sportster model against the 1964 BSA Lightening Rocket and the 1963/4 Triumph Bonneville rivals. (This goes along with an increased compression ratio). AMC were of course half-hearted in their attempt - they couldn't match BSA-Triumph's more modern unit construction engines introduced 1962 and 1963 respectively. AMC may have had an edge on chassis, forks and brakes though.
If i look at pictures:
i can see that this bike is like mine: the front 33 mudguard has not the Y stays like my G15 but the simple bridge; same pictures showed the long chromed grab rear fender support.
What i have not understood?.
The only issue seems to me that my bike has the original 33 wear (like in the pictures) but has the engine stamped CSR.
The previous second owner said he bought it in the last of 70th and had never changed parts.
Thank you for letting me know better.
