Pimped my naked Yamaha RD 350 YPVS daily driver

Hi 2-stroke afficionados. I pimped my naked daily driver on the next level: My 1987 RD350YPVS (type 1WW) in the “N“ (naked) version. See the first testride after setting the ignition and power valve curve of the ignitec-box and re-jetting the carburetors to the exhaust. Unlike in my full-faired (“F“) RD with Mikuni TMX30 carburetors, I use the original 26mm types of the 31K version here with a modified original airbox. Exhaust system is a used DN Performance, identical to the one in my “F“ - Version RD with “bean can“ silencers in the look of the stock silencers (thanks to Michael for building those). During the testride two problems apeared: The first is, that the idle jets (size 25) are to lean so it needs a bit more revs at lower throttle. I will change on 27,5 like in the original 26mm carbs of the 1WW. The second: As you can see and hear in the vid, the clutch is sliding when the engine comes in full resonance with the exhaust at 10500 RPM. Especially in the higher gears. After I recogniced that I avoided the range over 10500 RPM on my way back in fear to burn up the clutch. I will add three more of the reinforced springs in the clutch. At the time of the testdrive a mix of three original springs and three reinforced were installed, combined with heavy duty EBC clutch discs and Rock Oil Gear Saver transmission oil. But apart from the little problems: the thing runs and has a really wide and usable powerband.
