    OK guys here is a mind boggler,I did the 350x 400ex transplant following Matt 350x,s build using the exact motor mounts and engine mounting points, when I sit on the trike the chain gets looser when it should get tighter and its bugging me what is causing this, the only 2 things I think its is ,1 I have the rear shock link upside down? or the front sprocket is sitting higher than stock causing a geometry issue,I've built many Enduro bikes and 1 other 3 wheeler all ground up and never had any problems so if you know something I don't please chime in as I am stumped!
