Smog block off plates- is it worth the trouble

I have seen these advertised as a must for track bikes and was wondering what all the hype was about. Is this a good mod?

I didn't know he was you Dad, but he sure helped me out. I was so tired I could barely stand up much less think. It was definately appreciated.

I can't tell from the forum link whether you got the boost from the smog block off plates or the other mods. What is your opinion? And by the way I am running on stage one rejetted carbs. Would i need to adjust the fuel to air ratios again. That would really be a pain in the after just getting it done.

Yeah I take some medication that makes me more sensitive to the heat compared to my USMC days. It makes me feel like I am getting old before my time.

you have to get in and remove the smog block off unit and then cap up the intake.. all it does is reduce popping on decel.. I will tell you save yourself the headache and dont worry about it.. I didnt exhaust, velocity stacks, air filter and power commander all at once.. I wouldnt piece it together just ride it at msrh next month.. your bike has plenty of power and these little mods wont really make a difference you need the seattime like I do... thats the only way we are going to get faster.

My advice....learn how to ride the bike how it is. The bike is already fast enough. Unless your rossi, you will prolly never use the full power and potential of the bike. Putting money into these small mods isnt going to make a better rider.

Do about 6 or 8 trackdays, take a ty howard or larry myers race school and they can teach you how to be faster on the bike without those mods.

just my .02 cents...

All it does is allow the exhaust to pull in oxygen from after the air filter so that HC(unburned fuel) has an opportunity to heat up, mix and become CO(partial mix) before exiting into the atmosphere.

Will also cause popping on decel in your exhaust.

Instead of removing and saving the 2 lbs of weight for the whole system, you can take a marble and shove it into the rubber hose that leads out of the intake box to the pair valve system(be sure to put the hose back on, so that the airbox continues to get filtered air.

The pair valve system is for emissions only and wont change performance in any way.

It takes filtered, clean air and puts it into the exhaust after combustion; no way in that makes power.

10 fo, thanks for saving me the trouble. By the way, i am not trying to find every mod I can find just to shave time off my laps, I know that seat time is what is really gonna do it. I also know that the bike is still way faster than i am right now. I would just hate to be missing out on substantial extra power that required a simple mod.

The most informative people are the ones that ask

I told burnboy to put the marble in his tube to stop the popping on his new exhaust(triumph)

On the busa I was replaced the headers anyways so I did the block off valves.

If you're interested in feeling more pep, consider a change in the throttle. Change the turn ratio and you'll feel like you're getting more pull for the turn. Also requires less movement to full throttle if you have difficulty rolling the throttle all the way around(my normal riding position I have to drop my elbow on the 600 to get full throttle.)

Thanks for the info. I kind of like the cackle I hear when letting off the throttle though. I know it is probably a little childish but am still a kid at heart.
