Hi all, hoping some insight and assistance can be shed on my situation. My professor gifted me this set of Klipsch KG 3.5’s which had been in storage for ~20 years. Currently they are being powered by my Pioneer VSX-9500s and the source is a Yamaha CDC-835 (DEQ set to ‘Rock’ & output level set to maximum). See the attached videos to listen to my issue at volume knob level 6/30 (80-85dB) for video 1 and level 10/30 (90-95dB) for video 2. Media is live Grateful Dead ‘Bertha’ 9/19/72 from Dave’s Bonus Disc 2023 and studio Allman Brothers ‘Dreams’ from Duane Allman An Anthology Vol. I. As you can hear, there is some serious rattle & consequential harshness from Phil and Berry’s bass respectively. At lower volume, rattle and harshness dissipates and clarity and detail returns. How can this be remedied?

P.S. My Kenwood KDR-35 with a Grado Green Stylus gets acoustical feedback over 70 dB. Should I widen the speaker stance to try to avoid this?

today was the second ride where my chain tensioner must’ve slowly gotten loose to the point it fell off and got lost ending my ride short. Does anyone have any chain tensioner recommendations? The original one was all that came with the frame the second second one was one. I built myself at old skateboard bearings.

Seems like I’ll just have to constantly throughout my rides.

Hi, pretty new to mini bikes but have a general understanding how AFR and carburetors work. Currently have an idle that spikes and a good bit of gas coming out of the overflow tube. Idle screw is currently backed all the way out and the AFR screw is all the way tightened. Any advice or resource any of you can point me to? Much appreciated.
