Getting slightly better but still struggling.
Plug one gets quite carbon fouled but the rest look ok.
Thanks

"Being starved of fuel rings a bell",I had the same problem when we finished the build on my bike even with the larger jets, so we kept lifting the needle until it ran right, with my bike it would only run right with the needle in its highest position.

...the needle in the "highest position" did you put the clip at the bottom of the needle?
Thanks

Yes on the last notch at the bottom... try it on the last notch & then if it runs much better check the plugs if they are too rich lean them off on the air adjuster screws, on your carbs to weaken the mixture the screw turns out anti clockwise

Thanks,
I hate having to adjust the needle (is there a quicker way than removing it all apart?) but hopefully it will be worth it.
Thanks a lot

Yes its a pain in the arse on most carbs, but a much more awkward job on the PD carbs, yours are the earlier carbs so it should be a bit easier to do...hopefully
