Hi juntjoo, I can't comment on VB carbs yet as mine are on my "to do" list, but on my PD slide carbs I did a bench sync by raising the idle screw and inserting a small drill bit under the number 2 slide (base slide with no adjuster), then lowering the idle screw until the drill bit was a ...

I bench synced the first few bikes I rebuilt and they seemed to run fine. With your VB carbs, the sync only effects the idle. Once you get on the throttle, the sync no longer matters. I was, however, pleasantly surprised by how much more smoothly the engine idled once I got a vacuum tuner. I've nev...

what about rigging a solar trickle charger to the bike(Im in sunny SWFL). Place it on the tank? tacky

I just know I read these bikes don't self charge well and these hid kits help with that and provide better lighting. I recall reading something about a good product having hi and...

if you can get all the plates to close on a drill bit or whatever the guide uses accurately enough by hand what would be the need of a carb tuner? Do other factors come into play that affect the vacuum that require a mechanical DEtuning to get the vacuum consistent? Is that what it is? If not, and I...

The way it works is the valve is normally closed (a more accurate name for this would be a "vacuum allow flow" rather than "vacuum shutoff"). When you crank the bike, the vacuum pressure created by the compression of the engine opens the valve--allowing fuel to flow to the carb....

Well what about stock caliper paint?? only vehicle manufacturers have the right paint? well i guess I'll find out. maybe you didn't use "caliper paint" well I'm tripling up on coats

If anything, the lack of the T's would KEEP the bowls from filling--not cause them to overflow. They do not need to be airtight. A more experienced person than me once said, "If the part was not needed, Honda would not have wasted money putting it on there." thanks. there's always optiona...

thanks. you'll be telling me you told me so I'm sure

well I'm doing it. They'll be ugly without paint and I like red. Not sure if it will cause an eye sore on my bike but t whatever. we'll see... maybe in the future ill paint the rear brake, the hub part the same to give them something to match, and say 'hey, these are hot. they're brakes' actually I'...

reason I'm asking is because I've read mixed info, one person saying no t's caused bowls to overflow, where another said they were only for emissions and wouldn't affect operation, and I'm about to put my carbs back together and have fabricated replacement t's that doubt are 100% air tight(piece of ...

I'm redoing them cleaning them up took off a lot of thee stock black. I've got a dark red and a blue but the blue isn't exact match. I'm indecisive about color generally and don't visualize very well beforehand so just fishing for feedback. I don't need to use the paint I have but if the red would w...

I'm not sure fishing line is stiff enough. When I say guitar "string," it is actually very thin wire. I'm not sure how long your bike sat up before you got it, but I can easily picture all four carbs being equally blocked. Did you try soaking them in anything? Or ultrasonically cleaning t...

Strange as it may seem, I am not as familiar with the carbs on the CB650 as I am with the DOHC Honda carbs. I'm not really sure what that hole is for on those carbs. Have you tried pushing a length of a high E guitar string through that hole? yes, it's like a fishing string or related, something in...
