I would agree that something must have been really jacked up that carb. I mean I am no expert but the way I understand a main circuit to work is that fuel is pulled from the bomb site venturi when the air velocity is high across it and this sucks the fuel into the carb throat. Something must have been real screwy if it was still lean with no main jet!! Thats a pretty big hole for fuel to flow through.
tue or false, you'll lean sieze a single carb 62t at WOT

And stuff like this is probably the reason anyone starting a thread after getting advice from a builder shouldn't mention names. Sort of disrespectful in my opinion. I know you didn't mean it that way though.

Me too. I have a 61x with a single 44 and I hit reserve about 10-15 minutes or so before my riding buddy with a 62t w/dual 38's.
I will say though....I have also been told not to run wot for too long with a single carb.:shrug:Never took that advice, but I have been told that in the past a few times. In fact 2 days ago I was on a full speed run and my engine just shut down. Started right back up and was fine, but that's like the second or third time I've had that happen. ???
there is more that one way to burn up a motor but if you are going from two carbs to one carb you are choking the motor
you gotta think of a motor as an air pump
the only thing good you are gonna get from a single carb is easy tuning
since you only have one carb to tune for two cylinders
but back to the question at hand
a single carb isnt gonna burn up your motor
but a single carb not jetted and tuned properly most likley will

What is the complete motor setup your running. It doesnt sound like the single carb is the reason for no wot.
sorry again,i didnt mean you.this single carb/62t=seizure thing has been the common concensus around here for a long time.

And for what it's worth, I see it get blamed on the 650 kawi intake more than on the single carb of whatever size. It's mostly ATP mani or don't hold it WOT. The shop that told me not to do it unless you use an ATP manifold also seems to have the most nut huggers on here.

62t/61x ported & epoxied cases, race ported cylinders, coffman, 150psi, msd, 46mm carb, 2* static advance, boysen carbon reeds. same setup i ran on my ported 650
I agree, I think with me it was a combination of things, Speedwerx dry pipe that really revved, older style Novi that had a very different fuel passage inside (it was a longer path than normal), and the Riva manifold.

you could run 2 carbs per cylinder, and in my opinion I would tell you not to go WOT on that setup either.
timing, porting, compression, MSD = recipe for WOT blown to hell easily, if everything isnt pretty much in tune...

yeah i agree
its easy to make an engine blow up on two carbs , easier than on a single
its a issue of tunning
Its also good to tell your customers not to hold it wide open a well
makes it safer that your work will not blow up as well

Dang Wax you would think it better for business to tell them to run it wide open then,more repairs that way!

Yeah but when that you bueat engine melts down due to to much compression , to much timing or badly mismatched combinations of a hole lot of things then its easy to say you held it wot with your single carb
also its easy to build an engine thats good for just 1 second brapps much harder to make an engine that a customer can hold flat out for 40 secs +
like a race engine
