springer Posted September 5, 2013 Report Share Posted September 5, 2013 my first full chassis i build was from 065 1" and it was pretty fuckin light. can't remember exactly what it weighed, but was pretty fuckin light for a dual arm chassis.

m671054 Posted September 5, 2013 Report Share Posted September 5, 2013 Stock tubing is real close to .065wall if i remember right. i use .065dom 1" main rails 7/8 supports 3/4 subframe. for a full chromo you could go .058 1" main rails 3/4 .058 supports and 5/8 .049 subframe. If i remember it correctly the strentghs were close and chromo was like 5lbs less and 2times the cost for materials. it has been a while since i spec'ed it out but im pretty sure im close.

mx1986 Posted September 5, 2013 Author Report Share Posted September 5, 2013 ya this has been a pretty good learning curve. the first three times to the sand bar i think i lasted about 30 minutes and then i broke something but always something minor. now im working on a wheely bar. i should redo the front a arms cuz the geometry is off, but im ready to start a new frame now.

springer Posted September 5, 2013 Report Share Posted September 5, 2013 doesn't look like there is any rake in that frame, but i could be wrong. if not, that will make it feel funny. also, for a drag bike, doesn't hurt to run a higher caster number.

possum Posted September 5, 2013 Report Share Posted September 5, 2013 I know someone who does .065 main rails and .049 on the rest. With your weight id believe something like that will be good for you. Just an opinion. Quote Link to comment Share on other sites More sharing options...
mx1986 Posted September 5, 2013 Author Report Share Posted September 5, 2013 springer ur correct no rake. like i said first frame well actually first banshee i guess. i bought a motor and built everything around it. my bro has a gt performance single a arm with the rake and i guess i dont know y it would feel funny, my guess is that is helps with the front suspension if u put the rake in.

mx1986 Posted September 5, 2013 Author Report Share Posted September 5, 2013 Think I'm going with .o49 for main bars and .o35 for the rest Quote Link to comment Share on other sites More sharing options...
camatv Posted September 5, 2013 Report Share Posted September 5, 2013 that frame looks nice. try about 12* rake in your nose. up to 17* google suspension rake. there is a few video's about the way the shocks bounce over stuff that explains it very well. a lot better than i can explain here. also one of the reasons most yamaha frames feel like shit in the front end.

mx1986 Posted September 18, 2013 Author Report Share Posted September 18, 2013 Just obtained my metal in the mail this week the package weighted 27 lbs. Should be light. Quote Link to comment Share on other sites More sharing options...
