jbooker82 Posted December 10, 2007 Report Share Posted December 10, 2007 A float was removed so the bowl would hold more fuel. As for the jetting they would be the same size jet, just different brand. Kehin jets will have a K emblem on them that is how you know if you got real keihin jets. josh Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted December 10, 2007 Author Report Share Posted December 10, 2007 Ok the float was removed for more fuel, will this affect the carb? how so? also what would I have to do as far as jetting? Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted December 10, 2007 Report Share Posted December 10, 2007 I am not for sure if it affects jetting. I have never done that mod just herd about it. I run a dual outlet petcock on my tank. For jetting start out at what ever your builder recomended. If you have nothign to go by then here is a start. 165 main CEL needle on the middle clip Pilot 50 or 48 with the air screw turned 2 turns out. You should get a sync tool so you can have the idle screws in sync and the throttle cable in sync. josh Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted December 10, 2007 Author Report Share Posted December 10, 2007 Yea my builder gave me a starting point, Im more concerned about the float problem right know.. I dont know if I can leave it like that right know or I have to buy new floats.. when the carbs are up side down and the bowls are off and I push on the float or tap them, there is no play or anything, its like they are sitting on the bottom of the bowl...they just dont seem right..Isnt there suppose to be alittle bounce or something Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted December 10, 2007 Report Share Posted December 10, 2007 (edited) I dont know with the floats. Put the carbs on and hook the fuel up and see if fuel comes out of the hose on the carb bowl. If it does then the float hight is set wrong. You should be able to use the carbs that way cause people have ran them that way. Probably not a bad idea if your going to be using the stock petcock and go for wot blast down long straighaways. It is the cheaper solution instead of buying bigger billit fuel bowls. Maybe some body on here that has done this modd will chime in. josh Edited December 10, 2007 by jbooker82 Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted December 10, 2007 Report Share Posted December 10, 2007 only time I have seen the floats cut was when they where converted to alky. It will run with one cut, but it may run like crap down low! Your dealer ship should be able to get the floats for ya. Do you have another set of mains to compare the ones at are in it to?? Only thing I would be worried about is if the mains and dumps where drilled for alky. If they where, you will never get them jetted for gas! get a drill index and see what size drill bit will fit down the dump tube and report back Quote Link to comment Share on other sites More sharing options...

Item #8. Parts List: http://www.keihin-us.com/am/_media/pdf/pwk_parts.pdf Carb Tuning and Float Height/Adjustment: http://www.keihin-us.com/am/_media/pdf/slide_valve.pdf I know what my expectation is when I buy parts...and it may differ from others, but it is the same one I use when I sell them too!! I believe in full disclosure of all modifications or imperfections and I expect parts to be the same between components that are supposed to be a mirror image matched set...like jets should be from the same manufacturer to remove ANY possibility of inconsistency...but like I said, that is just me. Personally, I'd want dual floater floats in my carbs. Their buoyancy is what regulates fuel from under or over-flowing your carb which can lead to inconsistent fuel levels...richening your A/F while you ride. So if you jet after reading/plug chopping an artificially rich run, you could actually be jetting significantly lean overall. I think this result will be magnified by how smooth or bumpy the terrain is, so you can never get your jetting as consistent as it can or should be. Plus, the main reason for 2 floats is that if you have a float on only one side is: say your float is on the Right side and you turn Left...the level remains relatively constant. But if you turn Right, the fuel sloshes over to the left side of the float bowl, unloading the single float on the right side...adding fuel because the carb thinks it needs it...even though it doesn't. You finish your turn and you are now running rich. We all know that jetting is one of the most critical settings on our motors... See my Avatar!! :yelrotflmao: I'm not trying to step on anyone...especially someone on the HQ, but maybe if you had been told of the mods before you paid...you might have made a different purchase or price decision since floats run about $35-$40 each.

dajogejr Posted December 12, 2007 Report Share Posted December 12, 2007 If he was going to ride his bike at a 45 degree angle all the time, I'd agree with you, but for the occasional sloshing of fuel around the bowl, one float is suffice. To me, this thread is not about the functionality, it's about disclosure of what he was getting... Quote Link to comment Share on other sites More sharing options...
