I rode my 70cc mtb (shinobi sinner), pretty much everyday th' past two years. Since my license got screwed up, had to find a way to get around to work, get groceries, go to the bank etc., without being all tired and sweaty. Thankfully work is an 8 mile round trip, but I still have to bike if I need ANYTHING. (th' irony is I have two cars legally I cant drive) Watching daily weather reports is mandatory, not to deter me but to prepare myself for any possible nastyness. If it rains, I bring an extra pair of pants,socks, and shoes to work. A black handkercheif safety pinned to th' bottom of my backpack makes a good imprompto mud flap. When it snows, as long as theres a decent patch of ground to pedal start it I'm golden. When its cold (Michigan 20 below), I wear heavy sweat pants/hoodie over normal clothes, longjohns underneath. Two skull caps, thinsulite gloves, scarf, and shop safety glasses over regular glasses so my eyes wont water up on me. The deepest amount of snow i,ve riden in is 2-3". (the key is to skim th' surface of th' snow with BOTH boots WITHOUT dragging them. Plus, go SLOW) Also, use th' RIGHT oil/gas mix for weather conditions. 4oz. of oil dont cut it when th' temp drops. Shouldnt have listened to those stupid posts from another site. Recomendation: 5, or 5 1/2oz summer, 6, or 6 1/2 winter (if you re feeling gutsy) Run your engine like you just installed it. SLOW and WELL OILED! Lastly, dont use th' stock air filters they just choke your engine and or, vibrate off. Dont use th' stock spark plug cap, same problems, dont use th' stock kill switches. When I switched to just using th' choke I havent replaced a magnetto yet. Replace your rear tire with an armodillo hemisphere. A little hard at first ( depends on air pressure), but they' re tough! Th' small (081?) red star chain is MUCH lighter,and FASTER!!! The 415 may be big, but I had some kink up and get jammed in th' little gear housing couple of times. Anyway, The biggest hurdle of ANY daily ridden moto bicycle is th' terrain. If you don't do a lot of stopping and going ...youre probably gonna have alot less problems versus riding an urban route. Less wear and tear. Riding thru dirt, grass, whatever....LOOSENS things up some. IF theres alot of uneven surface coming up, or grass I unclutch th' motor to decrease any strain on th' drive chain and peddle through it until back on concrete. Sorry for th' long post....just trying to provide some insight. sunofjustice (brian)
