Okay every where i look online people have been saying the dg pipe and silencer are crap so is it really that worth it buying a new pipe and silencer or should i just buy a new expansion chamber and leave the dg silencer the silencer and expansion chamber are welded together in a really crappy way then i also wanted to know are the adjustable timing plates worth that $70 and i have one of those oko 30mm carbs i heard they are a pain to set up so maybe the guy i bought it from didn't set it up right and i wanna get as much otta this wheeler as i can power wise just so my buddy will stop calling it a little kids toy since his 400ex is sooooo much better hahahaha I'm sorry I'm just so against 4 jokes now its ridiculous i used to love them thumpers now i can't stand to see or hear them
