and at what rpm did the thing go fully open anyways.... you know before i did the mod....

other than that my bike is pretty stock...


anyone care to comment? please?

I noticed the same thing, it just doesn't have that ummph in first untill about 5k RPM. I'm hoping that when I install the PC it will clean up the low end.

 

The flapper fully opens as the 1nd set of injectors come on... I'm going by memory, but I think its
5500rpm @ >25% throttle. I could be wrong on the flapper part too

 

Hmmmmmm, I know these bikes flapper mod or not tend to do that anyway...but mine has become way more apparent since I did the wide tire kit and stretch, this being beacuse of the added weight to the bike and added rotating weight, plus a slight delay i imagine in the much longer chain. I wonder, if I undo the flapper mod will that help me get some torque back? Comparing it to a car...if you run a large intake manifold, its good for hp #s but lowers torque. Is this kinda the same thing???

 

that could be it........hell i am just gonna put the hose back on today.......

its gonna be a bitch though, it was so damn hard to get off in the first place...

 

Let me know if you notice the dead spot below 3,000 get any better.

 

will do

 

I dunno -- I completely removed my flapper (if you think the hose is a bee-yatch you ain't seen nothing) and the low end throttle response and slight hesitation went away completely. Best bang for the buck ($0) I've done on this bike.

You need to post up in the " Mods that don't work or were not worth the $ " thread that's going around now and let peeps know that it didn't work out for you personally.

Something that a lot of us forget is that even though these bikes are made outta the same parts going down the same assembly lines they are each a little different and some will not take to certain mods as well as another will. Doesn't really make sense but sometimes it works that way.

 

it was all in my head....i re-removed it.

what bike you got now chain?> still the 04, or did you buy the new one?

 

it looses a slight bit of low end tq when you do the flapper mod cause it doesnt have as much back pressure.. its only really noticeable leaving from a light nut other than that once your rolling its insignificant..
