Down On Performance

[John Jordan]

Recently Installed a Brand New HGM GunMetal on my MX and surprisingly I cant feel the rush I was expecting to get. All Stock except for the Exhaust System. Adjusted my A/F mixture to Factory Setting. How can I resolve this? TO THE MASTERS OUT THERE YOUR INPUT WILL BE HIGHLY APPRECIATED. Trying to RAISE THE FLAG OF OUR BIKE. TIA!

Yes it will decrease the performance due to the bigger elbow and also decrease the exhaust velocity. If you upgrade the pipe, its better to upgrade the engine also

I only installed a stock pipe. I already made some adjustments on the A/F setting and SP gap. Better than before.
