I cant help thinking removing this obstrucktion in carbthoat of my 74 550 will add alittle topend yes?but before i f---- -p mister Hondas
little masterpiece perhaps some of you guys have already tryed it ? i may have hard time putting them back if it flops.cold starting would be with some areosol spray perhaps.Ejoy the ride !

Try starting your bike on a cold morning without them before you remove them

Me thinks it'a a bad idea.

[svenD]

I cocld live with it seaweb,if it would pull to 10000 or so in top yes?

I am no expert but this does not sound like a good idea to me, you would have to take a can of starter fluid with you everywhere....

[svenD]

since i am already carrying chainlube and punkture kit(for long runs)this would be a #$%* Tyler,my plan is to fit a fueljet in the intake manifold and a small elektric pump for coldstarts.if-if-if!

Seems like a long run for a short slide! I seriously doubt that the gain would be anything more than negligible. Most factory carbs will flow more than the motor needs anyway. I'd look elsewhere for increases in HP and RPM's. Things like an indexing cam gear can usually yield more benefit for the price than removing your choke. electric pumps and jets tapped into the manifold? May as well ad nitrous instead!

[svenD]

sure enough Tbone,but when i am flat out in top I sense that the slides must be wide open to maintain topspeed indicating 100%use of the bores.gain a little here gain a little there is the idear-so the cam timeing as you point out must also get attention.

Sven, the big question is will it even make a difference at all. Maybe when the slides are wide open you're getting all there is. The venturi is the smallest part of the bore and will only effectively allow so much air through them regardless of the diameter of the inlet in front of them. A bigger bore carb may better address this situation. Sometimes there's just no more power to be gotten without bigger and better motor parts.

[svenD]

yes,yes,but maybe some poeple in the far east had the same discussion about 38 years ago and maybe such things as easy starting producktion costs and enough midrange ,were rated higher than flat-out performance.such considerations should not stop us from at least trying.

[tbone]

Try if you must but do it in a fashion that you can put them back in if it doesn't help!
