Took the bike out for a good run yesterday evening - running weak and lots of popping and banging on shutting off. Leaving carbs as standard not a option..............
Today I did most of bikeseamus' suggestions -
* opened mixture screw to 5 1/2 turns
* Needles raised one notch
* Turn and a half taken off of the CV carb spring
* Sync screw in 1 3/4 turns to open the second carb a little earlier.
The on road effect is very good - Pulling very well and no signs of a weak mixture. Bike hitting 95mph pretty quickly (with the feeling of plenty left to come) and is faster up a local fairly long steep (ish) hill that is always a good test.
Not sure it needs the 135 jet as to me seems fine as is now - Going to run it like this and do a plug chop. Bike is, I am sure faster, and pulling harder than it was standard so a worthwhile exercise
Thanks for all the help guys - I think I am sorted:-)
Cheers
