P.A.I.R/ Flapper Mod

I did the pair and flapper mod last sat. Not a bad mod to do. Would rec to anyone that hasnt done it to do so! I love the intake noise! While I was doing the mods I performed an injector flush and cleaned the T-Bodies. Throttle response was improved after doing the cleaning.
Another thing I would like to ask is, shouldnt the RC in stock form pull the front wheel up in 1st under power? For some reason mine has a hard time doing so. I dont know if it traction loss, or clutch slipping.... Any I deas guys/gals?

If you're using stock final gearing (16/40), it's probably geared so tall that it might not be able to.
I'm using 15/41 and had no problem lifting the front wheel under power in 2nd gear without intending.
And I wasn't intending to since I was partially leaned over while passing a car in a left hander.

Did you remove the whole system components or just disable the system?

I went through my invoices and saw I ordered 120 links when I replaced my original 15/41 sprockets.

Thanks for the weight info.
Mine already had the flapper components removed, so I never was able to weight it.
I've been trying to keep records of component weights when I remove or inspect items.
One day I'm going to obtain an all wet weight for my bike.

I have a 530 chain/sprockets.
I don't race it and the weight (4 Lbs of chain) doesn't bother me.

My thought on that was the 530 is a wider chain and the load is spread over a slightly larger area than a 525 or 520.
That way, it might allow more life out of the aluminum rear sprocket.
And I went with a hard anodized rear sprocket for even more durability.

You can use a 520 or 525 chain/sprockets.
The 525 chains are very good these days and are now standard equipment on the '09 GSXR1000's, or so I've heard (but not verified).

So should the chain have 106 links or 120 links?
