Doms CB550F1 project
McCabe-Thiele (Ted):
Are the carbs synched Dom, if 2 & 3 are a tad on the rich side or could it be float heights?
Do you suffer some hanging throttle issues?
DomP:
Id like to think the float heights are correct now, I spent ages fettling them with vernier calipers, I do need to tweak the carb balance a bit so that might settle the 2/3 issue. Hanging idle seems to be a thing of the past thankfully.
DomP:
I'm struggling to get some decent uninterrupted time on this at the moment, as it's a straightforward job and not time sensitive I thought I'd check my float heights on level ground, number 3 carb seems a little low but all others I believe to be good. What is the effect of a slightly low float height?
What do you all think? My carbs have a definite slope down towards the engine on the centre stand is this of significance?
DomP:
I've been out on a 15 mile run having balanced the carbs with a Carbtune about as close as I could get them. Things I've noticed are the following-
Just a recap on the set up, 550f with genuine keihin jets and carbs set to factory.
•Still bogging down below 3k to the point I have to drop a get away
• top end seems to hit a bit of a wall at 5.5-6k but I am being careful due to the rebuild .
•the front suspension bounces like tigger at about 30-40 mph, I wonder olive ive used too light an oil so may replace with something a bit thicker.
Other than that at cruising speeds on main roads its very smooth
Bryanj:
There is no power below 3,000 would be my comment, top end could be timing
