Hey guys, new to the forum, been riding a Firebolt for about 2 years now (previously rode a Honda Bros 650, then a Honda VTR1000 (and a motley assortment of other various v-twins)). The Firebolt is def the most fun I have ever had on two wheels so far and the machine is so user serviceable.
Still, I am having some difficulties that I want to iron out, I love this bike (never felt this way before, etc) so I don't want to ditch her just yet.
Have been doing a bit of research and I would like to ask for some insight from some of the veterans here.
Usual story; '07 Firebolt xb12r @ 16,400k's with a plethora of intermittent idling problems.
Bike mods: (not much really) EBR ecm, Jardine slip-on can, K&N air filter.
Recent servicing at 15,000k's includes: Fresh Motul 7100 4T 20w50w oil, new HD plugs (at 10,000k's), Motul primary case oil, adjusted primary chain, new plug leads (at 10,000k's), new oil filter, TPS reset, yadda, yadda.
You will have to excuse my use of the metric system, we don't use miles here.
Bike history: Bought 2 years ago at 4,500k's (actually saved from a savage that was going to chop it up and make a stunt bike).
Symptoms include: recurring idle surging, rough idling, bogging down when opening up the throttle past 3/4 turn (especially noticeable traveling at 100kmp/hr or 60mp/hr @ 3000rpm), stalling when stopped, coughing, stuttering. All these symptoms seem to come and go as they please, I may have a few months of solid riding and she runs hard and fast then I will get the occasional attack of engine trouble which can last and few weeks and comes and goes intermittently during this period.
My symptoms seem to be the same as the problems this guy has:

Pretty frustrating and embarrassing when it stalls and struggles (especially when my girlfriend is riding circles around me on her Kawasaki er6n and never misses a beat).
The one thing that I am yet to do is just replace the TPS outright.
The guy in the video link that I posted above had the same issues as myself, and most likely went through all the trouble-shooting, TPS resetting and heartbreak as I did before fixing his problems by fitting a new TPS.
I might as well try it, I have nothing else left to try at this stage, so I have ordered a new TPS and I will fit it this weekend.
Will I have to shag around with ecmspy and complete a TPS calibration before the running the bike for the first time or will it be okay to just fire her up and do a wheelie out the driveway?
I just blew my pocket money on the TPS itself so I don't have any dough left over for an ecm cable at the moment. Could just get the guys at the HD workshop to do it for me (pay 'em later) if I drop the bike off in my van, but they'll probably just try to sell me an xr1200x instead.
I also have the factory ECM handy; will I need to use this for the sake of trouble shooting? Will it be okay to fire it up with the factory ECM fitted with the K&N filter and Jardine on the bike?
Should I just set the bike on fire, bury it in the back yard and buy an 1125cr?
Any insight/tips/comments would be greatly appreciated before I crank her over with a fresh TPS fitted.
Kindest regards, cheers, etc.
