A few questions for those using the FCR35's on their Commandos....
This will pertain to the as delivered jetting and those who may have altered their jetting...
I'm wondering how the engine gets along with a quick opening of the throttle and the feel of the accerator pump in action.
In reading about people who've used the FCR in other applications, some complain of bog or hesitation, mostly in 4 stroke engines due to the short duration lean out condition upon initial opening of the slides I have further read about modified covers for the accelerator pumps that utilite an adjustable "leak jet" to control the amount and duration of the fuel stream injected into the cylinders with quick use of the throttle. The claim of the manufacturers and by the users of these products is that they solve this problem and the hesitation / bog can be dialed out of the response, making for a much crisper throttle.
so...... wondering if these adjustable leak jet accelerator pump covers would be a worthwhile addition to these carbs?
edit..... discovered these adjustable kits will not work with the FCR's from Sudco as they do not have a replaceable leak jet in their bodies (the kits require replicing them with a plug). SO they can't be used. in this FCR application even tho they are all advertised with working on ALL FCR applications.
