Throttle bodies loose from new!

Hey guys, if you buy a 2012 V 1000 make sure you have the dealer pull the tank and tighten the rear throttle body clamp at the intake tract or do it yourself immediately upon getting it home.

I waited till 2400 miles when I bought a power commander V to fix the back firing problem to discover what the real culprit was. The throttle body was half dislodged and I could literally pop it up and back down with one hand and little effort. Upon tightening the factory black slip clamp I found that at full closure I could still remove the throttle body. I replaced the stock clamp with a good old stainless band / screw clamp and now the strom back fires no more.

Was ready to kick myself from not doing this day one after reading about other peoples woes with dislodged throttle bodies but I also read about how lean the V is from the factory and I lied to myself that there is no way a brand new bike could have a throttle body completely unclamped from the factory. Well, it was built on a friday afternoon or I got the trainee who could not keep up the pace of the assembly line. I have about six other items I have modified to make the bike better or more liveable that I wish Suzuki would have just done themselves but I also have to remember I paid a fraction of what the competition charges for similarly capable bikes and in the end they don't hold a candle to the V and how it does multi faceted riding disciplines well. Tour, commute, throw it into twisties, etc. Love it.

Congrats on your new bike! Unfortunately, you found out what many of us did over the years.....that the frist time that your Vee backfired, it was then that it probably blew the TB loose. My K7 was the same. I hope that you replaced the other TB clamp as well. I went the TFI route for fueling and now several years later, am still happy as a clam with the way it runs.

Enjoy your bike and welcome to the club!!

The clamp was obviously never tightened and you are correct, it was probably pushed in to the correct mount point when built, they just never tightened the clamp, you could spin it around even after I reseated the TB. I did replace it with a good clamp and I have 200 miles on it as a daily commuter to confirm it is fixed.

The PCV is really nice but I am testing MPG. I am suspicious I lost considerable mileage with the map that was sent with the PCV. I talked to tech support at power commander and they have nothing to offer for my set up. I dissected my stock exhaust and removed baffling / spark arrestors and installed my own baffling and tips. (machinist and mechanic and I weld stainless regularly) I put a couple grand in options on my bike and fabbed allot of stuff myself, could not justify $900 for akropovics when 8 hours of trial and error finally got me the sound I wanted. Anyway, I need a map for free flowing pipes and a K&N filter as there is no dyno tuning facility anywhere near me. I read about the autotune using a bosch weld in sensor but read a few horror stories and I don't think I will go there. I am considering playing with the map myself with seat of the pants feel and maybe also putting a toggle switch on the thing to switch maps for a power map and a rain / economy map. Any ideas or information greatly appreciated from anyone. Love the bike, glad to be on this forum and pay my 20 dollars, it has helped me allot and I enjoy the contact with same bike owners.
