donated my old bike to my dads want for a timber sled. got a 137 aro installed. i figure a starter for him will be a must but im looking for any and all info. that i can get.... what oil are you running? pre filter??? (heard they are fine without it but i question that ) is their a slick way to warm the oil after ya trailer up to the hills or is it no stress (i would bet he never wants to ride colder than 0) how does a manual clutch work out?? if it turns out he loves it ill prob.. find a newer fuel injected bike for a donor but for now i just want to get him on one and see if its his thang. he has road bikes his whole life and very intrigued by these.. cant lie i am to any info is appreciated thanks
