To start this off, here is some background information. I have a 2006 zx636r with 8100 miles on it just put cr9eix ngk plugs in it irdium plug.

I not sure is it is me or not? I feel a power loss. Here are some of the reason I belive this, 1st gear wheelies are hard to get up Shouldt you be able to come up in second with just the motor? I would be racing my buddy on his 06 r6 and whenI reach 129 130 it is hesitent to keep going up in speed but it seems to go up after that ( shouldtI go up like a rocket at 130?). Now i took my muffler off with the servo threw a code to FI light. So i reset the computer by taking the the battery out for a little bit of time, Then my exhaust servo is making a weird a nose when the key turns on( not turning the motor over) on accesery. My thinking is that the exhaust servo is not open all the way and creating the right amout of air flow Needed. Nowam I able to ride with out the exhaust servo with theFI light on or would that create a power loss ? AmI on the right track or any suggestion would be greatly appericated, or has anyone expericed this problem? Oh, one more quick ? even tho i put the exhaust back on, would it still lose power. what could i do to fix this problem ?

Thanks Alot,

 

put it back to stock and see how it runs. you took the servo off with the stock pipe still on it ?

 

since you are on here evil, does the stock ecu convert back to a safety program lets say when a FI light is on? Thought they did. I know that disconnecting the cables to a servo only does not give you the FI light and you need to pin it for the 10. Sorry Brandon, am learning still.

 

Ya its back together to stock is there anything special that needed to be done ?

 

what do you mean pin it for 10 secs? dont be sorry we learn something e very day
