Ever see the Sat, & Sun papers for a Halfords cycle advert? The forks were on back to front! Also another national advert for a Hornby A4 streamlined Pacific 4-6-2 with corridor tender on back to front , some people know bugger-all!

I will just continue bluffing my way through which has worked for some time most of the time.

The other day (or more) I got around to fitting the new Continental Classic Attacks to the Mk2a... (I also had the rear wheel apart from my Moto Guzzi)

On the second wheel it was noted that having previously pumped the new tube a little for its talcum powder application it was now missing one stem nut and seemed a little baggy at fitment.
After inflation and bead seating along with some job well done and doing the next what ever it was job, I did notice a skinny section inflated tube that not only had a coat of powder but two stem nuts hanging on the handle bar of the Ducati Hypermotard which of course gave thought to what was in that Norton wheel.

I then proceeded to remove the 18 inch 120/100 section tube (from the Moto Guzzi and no doubt was hanging on the Norton) from the Norton wheel and fit the correct 100/90//19 one.

You need a wake up now and again to keep it real, not to mention better organisation

Ouch!
 
Good practise and no pinches or scratches so all good.
Here is an upgrade, all my bikes have IRC tubes for the most part, they seem to be the only ones that do not lose pressure.

The AT from new had a front that would lose pressure until I replaced the factory tube.
 
Thankfully this happened on the bench rather than the road

Worst upgrade.

I bought a Triumph 955 Speedtriple and on returning home from it's first service I checked the chain...NO play at all and oil overfilled...sigh!
 
Reliability, well really I haven't had another bike that I have owned for over 43 years except for my Norton that hasn't let me down, my other modern bikes are at most 6 years old so only time will tell if they are as reliable, yes the old bikes have there faults but isn't it our time to fix them faults.

One new Jap bike I purchased in 1976 had the exhaust silencers rotting within 6 months also valve seat gone on 1 cylinder, I had to recut and regrind all the 8 valves, back light permanently on due to faulty switch,, rear shocks gone. Oh, and the Jap rubber tyres were not exactly safe to use.

And that’s why we HAVE to do it ourselves...:cool:
Even the ugliest job, it’s less pain & suffering than the sinking feeling when you think: “what ELSE did the screw up?!?!” :eek::mad:
 
in the end all i really wanted was the rearset pegs, ... ended up with the whole dunstall enchilada fairing, clipons, tank and seat.. now working my way back to the original plan.
 
A lot of us have done it, it must have kept Dunstall in steak pies for months and months along with his favourite branded sauce.
 
Thought about this and decided not to degrade the TriSpark. So I would say any Dunstall part I every tried, they all broke.
 
And I will second that. to call a dunstall part an up grade is a joke.

in the day they were still flogging the 810 kit, but since i was starting from an 850, i couldn't see the sense in going backwards, good thing too, the engine is still in one piece....:D

Thought the 810 kit went on 750 engines. The alloy cylinder came apart in time causing more than a few to revert to 750 cylinders.
 
Worst upgrade.
I have well over 100,000 miles on an 810 Dunstall. Replaced the original mufflers possibly 3 years ago, which were original chrome still good but had been down the road on both sides. Dunstall rearsets still with original chrome and in perfect condition. As for the 2-1-2 exhaust pipe it has never been a problem or blown apart as reported by others (but I did actually tighten the clamps). And the dual discs are still going great and never had the wooden feel of a standard commando disc. The Dunstall cam and followers are in perfect condition. I will admit to destroying the 5 speed box when I jumped the bike and came down with a wide open throttle but I can hardly blame Dunstall for that. Dunstall clip-ons the chrome is now going and have been replaced with a clubman type bar as my back is not as supple as it used to be. There are plenty out there that seem to like to knock Dunstall, but my experience has been mostly good, and of course it is much quicker than any standard commando.

No the 810 kit was for the 750
 
The Dunstall street camshaft he used to flog to the unsuspecting public. I brought one and 3 of the four lobes were so far out when I finally timed it with a timing disc it was a joke- the bike was actually ran slower. All the performance returned when I refitted the SS cam I had taken out. Upgrade? More like a downgrade!

The negative reports from many of us come from disappointing experiences with Dunstall equipment. My own is mostly broken welds on rearsets and 2-1-2 exhaust.

You previously advised in another thread that you purchased your dunstall cam from a closing down sale. Another member suggested that it was from a reject bin which may well be the case. I know that my cam has the timing on all lobes within a degree or so. I also previously noted Comnoz comments regarding the hardness of Dunstall cams as being excellent, something that I can vouch for from the state of my cam and followers after over 100,000 miles. How many commando cams have gone that long. And my dunstall commando will still run over the ton with a gear to go. My only negative experience was the cylinder pulled the head studs which were helicoiled or bushed early on. It would have done 100,000 miles successfully since then, and I found the fibreglass disappointing but all the rest have been excellent.
