Now that Ive got the charging all up to snuff I got a chance to actually ride the bike. Its great at around town speeds but when i took it out on I35 she ran hard up to about 70 MPH ( which is now on the main fuel circuit ). Think I was at around 5,000ish RPMS.
Anyway the exhaust is the Jardine setup from back in the day. Cylinders 1 and 2 headers go into the left side muffler and 3 and 4 go into the right side muffler. When it starts to stumble I can hear a little popping coming from the right side, which tells me its either 3 or 4 carb having a problem. I set the float HTs at the prescribed 15MM per the service manual on all 4 carbs. They are all stock jetting and stock airbox and filter.
Some things that came to mind are...
One of the slides isnt sliding nice and free.
One of the carbs needs a float HT adjustment..but which way?? Tad leaner or a tad richer???
One of the floats itself may be hanging up?? New float needles installed too, by the way.
What are your thoughts and suggestions???
EDIT.... This is at wide open throttle b y the way..."tries" to catch but just seems to be a tad shy of grabbing.
