Early rev counter drive

Forums

Hi there - just fiddling with a 68 fastback, it has the brass rev counter drive on the timing case. It works, but the spade that engages with the cam shaft has been damaged and what is left is not long enough to engage with the slot in the camshaft. 

Does anyone refurbish these items? If not I can try and build it up with the welder, probably end in tears but will give it a go if I have to.

Camshaft Bush

Forums

Has anyone got any suggestions on how to extract the Drive side Camshaft bush from my MK3 crankcase, the timing side bushes came out easily with some gentle heat. This bush is Blind so its a bit more tricky, any ideas ?

Kind regards, Ian

Kegler Clamps

Forums

I am wondering what the general opinion is regarding Kegler Clamps. I have found that these seem to be available in the USA but cannot see a supplier in the UK. Are they not deemed to be an acceptable modification? If they are, is there a UK supplier? I would be interested to hear the views of any members who have them fitted.

South West London Specialist

Forums

Hi, would anyone be able to recommend a workshop in South West London area that could help me with a mk2a 850? I've recently acquired it and it's a mixed bag of having had lots of work but not entirely setup correctly, probably the Mikuni vm 36 causing a loss of power over 2000 rpm.

Thanks

Acceleration

Forums

Having recently purchased a 1973 Commando 850 Interstate,  I have been working through some issues and have finally got her running okay but she struggles above 5000RPM becoming very sluggish and jerky to accelerate.  Starts second kick and isles nicely when the choke is off, albeit a little high at circa 2000RPM.  Bike is fitted with a single Mikuni carb.  Any suggestions or help appreciated.

 

 

 

 

 

 

Clutch shims and circlips

Forums

Hi, I am wondering if I can appeal to the forum expertise with a quick question regarding the location of circlips and spacers on the gearbox mainshaft on my 1973 750 Commando. 

I bought the bike from a friend after he had completed an extensive restoration.  He fitted a belt drive conversion and, unfortunately, after 20 miles the clutch push rod adjuster came loose from the clutch center and was ingested into the belt and pulleys.  Both pulleys were toast, as was the belt and the new Alton stator.... 

AM26 Roadrider Tyre Wear

Forums

Not strictly a Commando only question, but I am hoping any AM26 user might comment.

This photo is of my rear Avon Roadrider 110/90V18, fitted to my Mk3 Commando in 2016, date code 3014, and having done just under 4,000 miles. A large proportion of that mileage has been two-up and I normally use 35psi with a pillion (30 psi solo). However, we have just returned from Spain and 400 miles of almost constant bend swinging, and I know the pressure was only 33 psi.
