Unhappy Revolution killer switch?

Recently I buted a 08 KLR, my previous bike was a Yamaha TDM 900cc great "double propose bike" not to good off road, I switch from 86 Hp to 47Hp and you could feel the difference in power, but by know 5 months latter Iím love with my KLR.
My problem is that when I change the muffler, put a Kerkker slip on which gave my great slow torque but when it gets up to 7,000 rpm beginning of the red mark, the bike doesnít respond over those revolutions.
I change the main jet into a 145 making the mix poorer but mean no difference, took the air filter off, no respond.
Those this bike has a revolution killer switch or something like it; please HELP.

Adding a pipe is not something that the KLR likes too much.

The Problem is that the head can only let it breath so much.
A more open pipe is good for low end torque, but loses it on the upper end.
Adjusting the needle with a shim and adjusting the pilot screw is about the only thing that makes sense to the KLR , and of course keeping the stock pipe. anything else is wasted money in my opinion.

If you want more horsepower.... head work and a larger piston is the only way.

Thanks Joe.

The main problem I have with this bike probably began at the brake down period on the engine, I drew under 5,000 rpm for the first 1,000 miles with a couple of occasions that I couldnít resist temptation and put the pedal to the metal, after the braking I change the muffler and noticed this problem, also I have a very noisy and bad back fire.
Could I do some thing about it?, if Iím not wrong back fire occurs when there is gasoline fumes in the muffler, is it a way to prevent this?, or I joust have to get use to my farting bike jaja.

What was the size of the factory jet? The backfiring sounds like it needs more jet. What does your spark plug look like, fouled "black", tan, or white?

Previous ride was a 2007 KLR Black/Silver, I miss it..
Looking to get back into KLR's sometime soon.

I'd guess his plugs are white...

You have a very lean condition, by what your saying. and the reason it's not reving up to 7,000 is it's starved for fuel. The backfiring is indicitive of running lean. Your going to need a larger main jet, or two shims under the needle and the main jet, or a combo of something to bring in more fuel.
I would fix it before any long runs.

Have you done the pilot jet adjustment?
