carburators

I just did a complete ovehaul of my cbr900rrs carbs but I did not touch the pilot screw to avoid having to reconfigure them. What problems might I still face involving the performance after a complete overhaul?

Re: carburators

Not taking them out may increase the risk for the slow idle system to be clogged. Standard adjustment for them is usually 2.5 turns out from lightly seated. You will need to do a sync as well, being that you separated each body. Not a huge deal, again only effecting idle.

Leaving the pilot circuit blocked is a long way short of a complete overhaul.
You have to clean the pilot circuit, and you have to remove the screw to do so. you need to ensure that carb cleaner and air flow through them.
Problems will be difficult starting, poor idle and poor throttle response.
You did remove the choke circuits and clean those out as well?

Re: carburators

Damn my main problems have been with idle and starting so I better take them out. Do you guys think I can only get a d head tool from a honda dealership? Bladeracer, where is the choke circuit on These? I only took out and cleaned the jets you see out in the picture.

I know you can buy them aftermarket as a mate just bought a "universal" set with four different shaped mixture screwdrivers.
The chokes are the pistons that hang off the choke slide.

Re: carburators

Ok, yeah I cleaned the choke circuit because I had to remove those pieces because of the rubber so I could dunk the carbs in carb cleaner. But I prevented the pilot circuit from being cleaned this way cuz I left the screws in. Ill look for a d tool but they are hard as hell to find. Thanks for the info guys. Ill be posting agin soon with my progress so keep a look out.

Don't just soak the carbs, you also need to force carb cleaner and compressed air through all the orifices to ensure they're clear.

Re: carburators

Where did you buy your pilot screwdriver? Does it have a d head?

They're not mine, I was at a mate's place and noticed the packet on his desk. The D is the one that told me what they were for :-)
I'll have to chase him up to find out the brand but he's racing this weekend and might be a bit busy.

Factory Pro make the driver and I've heard of a guy that used a 5.56mm case but I haven't tried that myself.

Just found this as well, don't know if it'll fit the Blade but worth asking him.

Re: carburators

If for some reason you can't get ahold of one, I have acquired 4 of them over the years from Factory Pro kits. I'll send you one, no charge. Yeah, that translates into FREE.
