Well I jumped on the band wagon with the removal of the secondary throttle plates on my 06 10r.:scared I was a little nervous because I have spent so much time gettting my bike right were I wanted it power band wise.:eek:hno It wheelies real easy in 1st 2nd and third with my new map and I didnt want to ruin that. :crazylocoSo I first bought a used set off Ebay for $50 shipped to my door. And guess what it was missing the secondary plates!:rant Oh well didnt need em anyway. The plan was not to only remove the plates, but I never could figure out why everybody left the secondary shaft in there as it definitely would disrupt airflow at upper RPMs.:headscratch So I took apart, and removed the butterfly motor and shaft sensor. Realizing I would pick up codes, if they were disconnected, once I removed the shaft I pluged up the holes and cut the shaft down welded it back together, and mounted the controls back on a apparatus that would allow the CPU to think it was still controlling. I plan to replace the motor and sensor with resistors soon, but wanted to test it out.:mfclap Holy crap the throttle response is instant:scared like right now. It didnt gain any or loose any torque which makes me a happy camper:mfclap. Its animal:eek:hno It defiantly lost user friendliness.:rant For example cold start idles real low, but once warmed up its fine. And on hot restart you have to knick the throttle but so far it doesnt bother me:mfclap And on the possitive side no more back fire from removing the exhaust valves :crazyloco So check the pics and I wil keep all informed.

This didn't make throttle response rough at different points? I tried it on my 6 and the throttle definitely wasn't as smooth. I have an X-tre and might try some velocity stacks but I like the linear throttle response with the secondaries in.

I think you might feel what I described as user freindliness more on a smaller displacement engine. You can get away with it more on the liter bike without giving up the unpleasantries. I can understand what your saying though cause I do feel that difference. Thats why I will give a final judgment in a couple of weeks after I live with it.

Living with throttle body mod.

I am Sooooooo happy with the new set up. Its really tight. I thought before it didnt give it anymore torque but I think I was wrong. Once I got over the scary real fast throttle response, and started using it I do think it has picked up on the bottom. 3rd gear wheelies easy as pie. And I do like the quick throttle. I am going to get it dynoed to see whats really up and will post results. I am going to set my track bike up same way.

Has anyone with an 08 or 09 ZX10R done this mod? I'm contemplating it after seeing the big gain my buddy had on his 14, but don't want to learn by trial and error. If it's already been done on a 3rd Gen bike I'd like to see some lesson's learned and hear some reviews.

Thanks
