i am not sure if there is gonna be any specs. Because when you put weight on the front end the tire driection changes a lil bit. I say just do it by eye.
Welcome! Also, good advice.Hi, I just registered in this forum but have been watching it for a while. A little advice about the tow of atv wheels. Towing the tires IN or STRAIT ahead will make the bike very unpredictable and scary to ride at any speed, they need to be towed OUT by 1/8 of an inch. If they are towed strait ahead or in the front end will dive with minimal steering input I can guarantee you will not like the aftermath. In case you are wondering I work on ATVs and know first hand what effect tow in has on stability (long story involving pain and blood and broken bike parts )
