stock topend? i donno, there arent many choices for the stock angled port cylinder.
i was underwhelmed by the peoples pipe when i put it on a Tomos A55 stock cylinder on an E50 (very similar to a stock large port korado/magnum topend). maybe the newer redesigned version with a smaller header diameter is better?
Promo pipe is super loud, the baffle tends to fall off, and header hack+weld required for an angle
techno boss...super loud and no low end
i live in mountains and the hill climbs are no problem
with the cheapest 70cc TCCD and a treatmetric clutch im very happy with my MLM Cali. i only need about 10 yards of flat ground acceleration to climb steep hills from a dead stop. my sprockets are 18x45 but im running tomos A55 mags that are only 16", so more like running 16x45 on 17" wheels
