01 v92 deluxe
So I've done it all on the list.
Throttle Position Sensor
Throttle Body Gaskets (Cleaned throttle bodies thoroughly went from 1k rpm to 1500)
Cleaned tank and chunk screens
Replaced exhaust gaskets
When I'm on the bike, it backfires like crazy when the fast idle is applied (during initial warmup), but after about 60 seconds if fast idle is turned off brings it down to a mellow and solid sounding 1k rpm. It's hard to keep it (fast idle during warmup) at 2k rpm, requires constant attention and there is a hesitation. When you're on the bike, 1st gear gets you to about 15 mph before you feel the need to change gear, 2nd goes to 25, 3rd to 35, and 4th to 45. But, all through those gears from 2k to 3k rpm there is a major stumble (seems to level out a bit after 3.5k). It feels as is if there is fuel coming in spurts, it lurches forward, then bogs down over and over again, even as the gauge is reading 3k rpm and I'm holding throttle steady for a while (all the while during this surge/bog dance the needle stays constant on the tach). So before I go assuming anything, most likely culprit seems a sticky fuel injector as this is a v92 that has sat for 6 years. Pretty much all of the above was done not only as it was needed along the way for troubleshooting, but also because the poor beast was mistreated and needed to have the work done.
Before I go assuming its a fuel injector, any advice on what else to check. (Oh and just in case, I ordered an air temp sensor for it as well which I'll drop in, though I doubt it). I also sprayed contact cleaner on pretty much any connection I could find (minus the fuel injectors as I got the spray after I put the throttlebody back together). I REALLY don't want to pull that throttle body off again. Not that I think its going to be as hard the second time around. It's just as a single dad with majority custody, finding 15 minutes where I can do it at a reasonable hour without an interruption is on my christmas wishlist.
Any advice would be appreciated (especially advice that solves the problem and doesn't require me to pull the TB off, heh). Thanks.
