Flew to Qld yesterday & paid for the Le mans MkV. One thing I noticed is the heavy throttle. Not being around Guzzi's before, is this something you get used to or is there something I can do? I had a fairly big accident about ten years ago & have lost some strength in my wrists.
Thanks again for your help

Warren,
It's a typical Carbed Guzzi trait. I'm sure there are others on here with a solution to this. My take is to replace the carb slide return springs from a suitable Ducati. Ensure that the throttle cables are well lubed and the cables follow a route that creates smooth bends. Polishing of the carb slides will help the return with the lighter springs as well.

The MK V has the PHF 40's with the bell tops. Evidently you can fit a lighter slide spring from a PHF 30, part No 1793 7167. (Guzziology)
If this isn't enough then you will need to change from bell tops to flat tops to remove the side lever spring from the equation. This will also involve new throttle cables as they have a different end.
The MK III has PHF 36's. There is no easy spring replacement for them.

In the process of putting kits through my PHF36's in the Le Mans, I noticed that the throttle spindles at the top of the carbs (the shafts that the levers turn) were very stiff. Lubed them with WD40 to free them and then with light machine oil and lubed the cables (NOT with Chain Lube but with light machine oil) and now they are beautifully smooth and light compared to what they were.
I've found that chain lube in cables is not a good idea. They end up getting very stiff and "doughy" especially when cold.
Have a look and give it a try.
