Engine

BROS's engine type is SOHC 3-Valve, Liquid cool, V-Twin-cylinder, twin plug....... To sum up, engine base is "NV" family's engine. Main change point are bore & stroke, cut of cylinder's fin, surface color, etc. It was set low and middle speed type. Mission was changed fifth from sixth.

Exhaust pipe of rear cylinder is traced around crankcase and collecting. But, be careful for burn. I have got burned when setting pilot screw.

Wow! Slickly!

I think about liquid cool engine. I think that finless engine is beautiful. But, many naked motorcycle's engine has many dummy fins. Why finless engine is beautiful? Because liquid cool engine must have cooling capacity enough. But dummy fin is added. What is this? I think that it is against fanction beauty. After all, dummy fin is dummy...... By the way, I decide for me that to think beauty engines are CB-1, GF250, VT250 SPADA, CBR250four, Zeal, FZ250 PHEZER XANTHUS, FX400R, etc. Dummy fin is OK to four. Somehow I think that their are not popular motorcycles...... 2cycle engine is not symmetry. So, BROS's slickly point is 80 point. (^^;
