There is a screw on each manifold. I think would like to try the vacuum
gauge to set the carbs. I went to jcwhitney's site to check out the
vacuum gauges. Do I need the 4 gauge one? what do all the guages do?
do I need to get a special hose to connect it to the manifold hole?
You mentioned something about brembo bleeder screws, aren't they the
screws on my brake with the funny nipple?
Once I get the vacuum gauge on what screw should I be fondling? the
pilot air screw (the small one flush with the carb) or the throttle
slide stop screw ( the larger one that has the exposed spring).
You may be rolling your eyes right now as you can see I am new to this.
Thanks, Joel

I find the best way is by vaccum. You need the "mercury sticks" or just two accurate automotive type vaccum gauges work too.If you use vaccum gauges you will need something to pinch down the hoses to dampen the needle fluctuations. You can use two brembo bleeder screws to screw into the manifolds to get your connection. I have an inexpensive J C Whitney carb balancer set (4 Vaccum gauges mounted to a board). First make sure you have some slack in each throttle cable. 2, warm-up engine. 3, bring rpm's up to approx 3500. 4, adjust cable adjusters until both cylinders read the same (make sure you still have a couple MM of slack when you are done). 5, bring to idle. 6, adjust both mixture screws to best idle. 7, adjust the idle stop screws until you get the desired idle and gauges read the same. 8, repeat steps 5, 6, 7. Don't worry about the suggested settings. If they don't balance you likely have some small jet or passage way in the carb plugged with swarf. Some may disagree but this procedure works on anything. Good luck and ride safe. Kevin 98 EV 97 Sporti 80 v50++ 75 T-3 74 Eldo |
