in front of the crank arm

if i understand you right, no, the chain would still rub on the bottom bracket and chain-stay that was my original plan. but that's what i get for building the bike before i had the motor,

What if there was an idler at the bottom front side of the bottom braket (I am thinking the BB is where the crank is)

hmm , i will give it a try thanks man !!!

after lineing up the chain on the sprokets,idler and motor,,use the chain breaker to get the slack out of the chain and then a mild "spring" tentioner 1/2 way back too the axle on the bottom chain for any play that is left

we got the motor in and running this is my first mb and i am impresed with the power the 48cc engine has, i didnt open it up but what a blast! i had to redo the chainstays and bottom bracket so i could get more room for the cains and the 1 pece cranks clear the egine much better, so now all thats left is to clean up the wiring , mount the tank ,paint , and put the whells and tires on i also need to find a artist to paint emblem on the tank
