Good morning TT,
I owned a 07 Yz450f and bought the 500cc Cylinder Works Big Bore Kit with Hot Rods Stroker Crankshaft, and had it installed professionally by an independent motorbike shop owner. I ride my bike 50/50 on the roads and in farmland, I have a license plate, so I was hoping to get more good usable power on the road.
However to my surprise, the bike vibrated so bad my butt and hands hurt and you could see it shaking, and the power was definitely more torqy but overall seemed to NOT be better for high RPM cruising, it almost seemed HARDER for it to cruise at high RPMs? Like it was working harder and revving higher. Is this normal or is it the stroker crank, do I absolutely need that stroker crank if I get this kit installed in the future? Any ideas appreciated.
So I'm getting a new 2010 yz450f OR a 2010 kx450f because their on CL and I lost that 07 in a house fire, and I'm wondering if the installation was bad, or if its just the stroker crankshaft that maybe isn't good for what I want (sustainable high RPM cruising)? Idk, the powerband seemed more responsive but more flattened out and just crazy reckless not as steady and overall efficient for my situation. So yeah, should I just not do this if I get a new bike or should I do something differently? I just thought the extra CC and HP would help with being on the road rather than hinder, I already had the sprockets maxed out to cruise better too so idk, THANK YOU for your input,
