Hello friends, I just put a fresh gas mix in after not riding for the winter. 5% motul/regular 87. I ran it around the blocks a few times and started losing power. It felt like it was gasping for air if you get my meaning. After bringing it back I throttled the engine to try and work out more cobwebs and the engine started oscillating in RPMs while I was keeping the throttle at a stable place. Attaching a video and it starts about 5-8 seconds in.

I have the feeling Im going to need to do some tuning and parts replacing, but anyone have thoughts?

Im competent with a wrench, but not a mechanic, more like a 4 out of 10.[/url]
