What's up guys,I'd like to upgrade my stock carb on my '87 230e. Would the 28mm mikuni flatside from bikebandit work good with my stock bike? Some help would be great. Also I need to get back rims, where can I find the best deal? I need to check my valve clearance,is there a way to tell when your at TDC without taking the pullstart off and allining the time marks? Thanks again,this site is a godsend!
