Well,
Thanks for the replies lads
Gen 2 (which is mine) doesn't have the screw adjust your correct. That also means that adjustment at the throttle does nothing.
Called the agent and booked it in.........................but then I thought fook it I'll av a look.
Gotta be something at top end 'cos that's where the injectors are, so off came the seat /tank lifted ........low and behold.
I just gently pulled on the pipe and look what I found
Its 7pm so no shops open now (not that I'd be able to get that size pipe off the shelf here in Dubai!)
So cut it down, there is enough on the pipe to allow for this. while I was at it I nicked a piece of air pipe from the fish tank and slipped it over the original pipe.
Sorted ..........................Happy man .
Although I haven't road tested it yet !! Ill do that tomorrow and if its ok I'll cancel the trip to the agent.
Thanks again guys as I learned something here
