Oh sorry, didn't quite understand your questions, no prob, yes you can use the pingle shown as long as you have the proper adapter plate for that model . on the oem model the one in the middle use a vaccum to open the diaphram(sp) to allow the fuel to flow, as with the pingle all you ahve to do is move the lever to the on position.
Papi I got one of those ordered for my bike too (has a reserve) My gastank is different than yours though. My petcock is to the rear close to the rear shock. You might want to ask around and see if that one you have will work still since it has the reserve tube on it.Good Luck
thats the EXACT pingel i installed on my 96 1100...i didnt plug up the vacuum hose though...maybe the guy at the bike shop did while tuning it up...he said i had a vacuum leak! the only problem is with the lever being so short! you need to rigg something up to shut it off and on...unless your petcock mounts in the back like bobbychet's (thats why he said he can reach up under the subframe and turn his off)
im having second thoughts about throwing this thing on...
it doesnt seem worth it. hell i even dreamt about the damn thing last night... i wont be able to reach it and then i have to bore out the diameter of the tube just to get it to fit in the tank and then i have to constantly turn the thing on and off or i'll flood it, vaccum problems...seems like its going to be more of a headache than anything else...
Papi if your just using stock carbs then maybe just rebuild the old OEM petcock.
I'm using Keihins which use more fuel thus needing greater flow.Just try not to turn the OEM petcock to various positions all the time, they wear out quickly.
