I recall you changed the main jet in the primary carburetor from stock to 165 to 155. Do you think the 155 jet is spot on? (you have the airbox snorkel out right?).
Who sells the jets? Do you have the part number for the 155 and 160?
One more thing… do you think it is better to remove the subframe to get the carburetors out?

The header nuts come off easy - I did them when I first got the bike (with 6000km) and always use plenty of copperslip on them.
I took the snorkle out - but it didn't seem to make much difference so I'm running with it back in. I have a selection of mikuni jets (button head with a slot) which fit - so no part numbers. I only did the primary carb, coz the secondary needs special jets, but Yamaha only do up to 145 which is the std anyhow!
As for getting the carbs off  I just undid everything (but not the sub-frame) and struggle for 10 mins to get them off - that was easy campared to getting them back on  Probably best to drop the subframe
I do have one running issue which is at full throttle - like when giving it some to over take on faster roads. This bike hesitates, and seems to die and splutter every time! I've checked fuel flow to the carbs, buy wonder if I just need to get a bigger main for the secondary carb:confused1: Rest of the time its OK, starts good, idles fine..etc. Its just at full throttle in taller gears/longer blasts at hi-revs of more than 5 seconds
I've checked all coil connections, re-done HT cap fitting & swapped plugs, etc, to no avail.
