Intake Port alignment

The intake port on my front cylinder head (Darmah head) is not centrally located between the manifold studs, the port is a couple of mm closer to one stud than the other - whereas the the intake manifold port is central, hence a 'step' interrupting the gas flow. Easy enough to remedy, but I was surp...

Re: Pulling the Head

It's over 30 years since I overhauled a bevel single motor, but my memory tells me you don't need to touch the cam nut just to get the head off but you can be cunning and loosen that nut before you get the head off as a cheat. Then you just set the motor to TDC on compression stroke, undo the head n...

Re: 750GT Rolling Basket Challange

Thanks for the reply Geo - I'll just keep the springs I have, and machine a slight recess into the gold valves for a spacer to locate I think…I don't like the idea of more metal scraping inside the fork tubes than is necessary.

Re: 750GT Rolling Basket Challange

Just got the emulator adapters and damper rod replacement seals from Race Tech. I expected the adapters to be a slight interference fit on the damper rod, but they are actually a slightly loose fit. Probably not a big deal. They are slightly different than the ones shown on the Race Tech adapter pa...

Re: Condor a350??

What a great idea - if I had to ride a Lambretta or Vespa more than 20 miles I'd want to take a bottle of something pretty strong to dull the boredom! I mean they can be fun in the city but sheesh...if you can lay your hands on a Condor 350 in good condition then go grab it and ride that thing! I re...

Re: marzocchi shocks

Sorry I misunderstood Anthony, what a dill! I was thinking front forks because they are so fresh in my mind from pulling them apart - which should be called forks I realise now of course. So did your shockers in fact need gas? I remember some of those Marzocchi shocks had air reservoirs in the late ...

Re: marzocchi shocks

Hi Anthony, that advice you got doesn't sound at all right. Gas doesn't sound like a relevant factor at all when you understand how these forks work. If you want to restore the bike accurately then the only gas in them should be air and that's at atmospheric pressure as best I remember them. A secon...

Re: New addition to the herd

Well done you! I lusted after one of these when I was in my late teens, but ended up being talked into a Darmah and strangely a 250 silver shotgun (I'm 6'2" so the Darmah was a good fit and the 250 ended up in Japan). The Darmah is long gone now and I've got a round case twin. In the meantime I some...

Re: 1974 GF 750ss steel intake manifolds

Thanks Peter, mine's a replica built up from modified GT frame and GT engine. Sorry I don't know of any original gf engine cases currently available but if I ever hear whispers of a set I'll get hold of you. Might be an idea to PM me with your contact details so I can remember how to find you in my ...

Re: 1974 GF 750ss steel intake manifolds

Peter I don't have a pair, although I too would like to locate a pair so if I come across any extras I'll PM you.

If you're building up a green frame replica or restoring a genuine '74 SS, I'd love to see pics of your progress.

Just sayin...

Re: WTB Marzocchi Top Triple Clamp

Just thought I should mention that a top clamp from a 900SS or Darmah would also suit my situation - as long as it's Marzocchi.

Re: WTB Smiths 250kmh speedo

Tim came to the rescue, thanks Tim I'll look out for the speedo in a month or so once it's restored! I'll eventually have a pair of working '74 750GT Veglia gauges available (i.e. matching tacho & speedo 150 mph) so if anybody is looking for such a pair then please let me know before I list them up ...
