if it is a fuel delivery issue, it would be solved by manual petcocks,
right? [/quote
Maybe - could be Petcocks, fuel line, fuel
filter or float level.
Better to troubleshoot the issue and find
out what is wrong before just throwing parts (and $$) at it. You'll save
both time and money this way.
Troubleshooting is best done by
dividing the problem in half... You know you aren't getting enough fuel to
the engine (because it works with choke on, but not with it off).. so
where is the half way point of fuel delivery to the engine?
The Fuel in the float bowls.
Start with verifying
that your float level is ok using a clear tube hooked up to the drain
valve, and compare it to the flange level. Should be about 1-2mm below the
flange.
If you dont' have enough fuel in the carbs, you have a
fuel delivery issue or your float level is set wrong.
If fuel
level is good in the bowls, then you have a clogged idle circuit (idle
jet, air jet, related passageways), or a vacuum leak.
Not saying
that Syncing the carbs is a bad idea, or that running a manual petcock is
a waste of time (I prefer them, hands down).. but check these things
first, because you can check them with the carbs on the bike.
If
the problem is fuel delivery to the carb, the single carb setup won't
solve anything.
If it's the float level, then replacing the
petcock with manual won't fix it.
Find out what is wrong and then
decide how you want to fix it. - There are often several solutions to most
problems, once the problem is understood. |
