Re: B44 Old girl starts, needs lots of tickling to warm up then go's well!

When you are doing 100mph with the throttle wide open I love where you are coming from with this but have you seen the size of my rear sprocket?? Ref the Amal choke working oddly - you're not wrong on that, I know that this sounds a bit naive but, is the carb 'choked' with the lever pulling the sli...

Re: B44 Old girl starts, needs lots of tickling to warm up then go's well!

Hi Cat - so a quick update - I started with the timing and carb settings as the choke kit took a couple of days to arrive. When I initially timed the bike I set my TDC and used the Electrex markings to set the advance at 28' BTDC. And that's where it's been ever since. She has always started, I have...

Re: B44 Old girl starts, needs lots of tickling to warm up then go's well!

Thanks eeb - that's another nice and easy option to test out and it makes sense as it relates specifically to enriching the pilot system. The symptoms are of it being too lean at idle and not responding well to the throttle. How did you come by this? As you say it is contrary to most of the tuning t...

Re: B44 Old girl starts, needs lots of tickling to warm up then go's well!

Hi all - I know it sounds like one of those dodgy ads in the personal columns, not that any of us read them!

If you put a short piece of round stock inside the dowels, you won't crush them. !/4" bolt almost works, you merely distort them, instead of crushing.
