dt502001 Posted November 3, 2014 Share Posted November 3, 2014 What I was saying is if you haven't checked your swing arm bushing wear, cush drive or sprocket then you might as well go by the marks on the swing arm and a tapemeasure. All the little other things add up to much more in chain deflection under actual use. The Idea is good but still leaves alot to the person using it and how they inturpute it. Drewps HM is as good as any store bought EDIT would you not rather align the whole bike and not just the rear of the bike ? Also if the motor is not in straight then it will set everything off. Yes it takes longer but if you just need to tighten up the chain then why bother with the lazer? The front triple clamps also come out of alingment over time and should be set back to make the bike track straight. It is worth it to me to take the time every 3rd or so adjustment of the chain to me. Link to comment Share on other sites More sharing options...
dt502001 Posted November 3, 2014 Share Posted November 3, 2014 I dont do photos of how to do things,but if you get 2 pieces of 90 degree angle iron ( bed frames ) and check them for trueness.( easy to do by streching a piece of string over it ) Longer then your bike wheel to past the front wheel Then with a couple of clamps you can make the whole bike straight,,, loosen the triple clamps and the rear wheel,,set that all 100% then if the motor is still out then move it, Before you try to adjust your chain or as your adjusting it Not like you cant to make the motor aling with the rest,, the bolt holes have lots of adjustment and a few shims and BANG your bike is better than most others that look the same.Handels better than Joe Blows.
