Where all Commando 750's Between #'s 200976 and 211110 Combats ?
 
Not all Commandos produced between 200976 and 211110 were Combats (Hi-Riders for instance, were not Combats).
From what we know there appear to have been a few Combats with lower serial numbers than 200976.
It's less likely there were many, if any, later than 211110.

Any particular reason for asking?
 
The "C" stamp on a Commando head is the easiest way to fake a combat.

It has been said in jest, but is entirely true: "There are more Combat Commandos on the street today, than the factory ever produced".

I could give you a reason why not wanting a Combat:
Combat is the only Commando without a large sump filter so all (metal) dirt will directly flow into the oil pump :cry: Serious design flaw :!:

All 200000-on 750 Commandos, Combats or not (so all '72 and '73 750s) were without the sump filter.

Ouch.....that makes it even worse :roll:
 
I don't buy the published numbers.....matching # 200205* was a full combat (tune) interstate and was bought like that by the original buyer. My friend Frank D bought it from original owner a long long time ago and still owns it. I worked on it back in the late 80's, to put a norvil belt drive and one of my first 15 clutch rod seals. I don't think it ever had any previous molestation or saw any evidence of detectable work like a rework to make it a combat.

*Edited by the moderator as dynodave later discovered the number was 202005.

Has anyone checked that number with the NOC records officer. ?
If the records exist, they can advise build date/dispatch date.

Without that info, who knows what might have happened at the factory - or even at the dealers.
 
But the despatch records do not tell you if its combat or not so what's the point of asking.
 
I have a Combat, the records were silent on what variant my bike was so that negates using the records, if it says combat then fine but if not then it means nothing as it could have been a combat.
 
Recently acquired 208498 checking in here. Glad I checked this thread AFTER I bought mine last week :lol: :lol: :lol: :lol: But, the guy I bought it from, you could just tell he was an honest cat, so I had no reason to doubt him. He told me ALL of what he did to it, showed me the unique Combat items, and I knew it was legit. Glad the numbers are in the range

As a mater of interest how much crud have you taken out your sump filter? And by all accounts the amount of oil the combat belted out their breathers all the crap went with the oil so the fresh oil top up would be as clean as a sweetie , so what's the problem.......apart from bearings ?!!!! A few buggered crank cases and the like so all in all regardless of engine numbers a real winner from Norton only recently surpassed by the 961.

Well after some time beyond their release the Combat gained the imputable reputation of oil pump destroyer. Ever wondered why Norton re-introduced that sump filter again to the later 750 and all 850 Commandos :wink:

So you've not actually taken any bits of crud from your big filter and maybe there is a perchancity that oil pumps perform better when they have oil to pump rather than run on the dry side , the main bearings also seem to perform to their full potential when lubrication is available 100% of the time. So what's going to go first pump or bearings? Maybe it was a mod to far in 72 but the 828 muted in some circles as the "best" ever commando (mk2/mk2a/mk111) take your pick lacked imagination and the fallibility that made these bikes so outdated and yet so desired .

And to quote my ten year old daughter " it smells of motorbikes in here" only 750's give you that.

But, we did this yesterday: between-200976-and-211110-all-combats-t26476.html#p350824

They didn't reintroduce it on the later 750s.

L.A.B. you are almost right however you forgot about the (later) 750 short stroke engined Commandos (I know these engines had in fact 850 cases but still they were 750 Commandos).

I didn't forget.
I didn't mention them as the 750 short-stroke engines were built using 850 cases so as far as I was concerned they don't count as they were not true production models and the existence of any actual 750 short-stroke production Commandos is yet to be proved.

Edit: I think there may have been the odd report of very late long-stroke 750s built with '850' cases but it seems they were either oddities or relatively few in number.

:?: you completely lost me there :?: Presence or lack of a sump filter will not affect lubrication availability at all :!:
