    Wiseco piston to cylinder clearance

    Ok,on the box clearance states 0.002"/.051mm but I've read that this can be a bit tight (sorry this is for a 83 250R) What are your preferences/experiences on this?
    Also do you run these piston in any different from any other?Any help would be greatly appreciated,thanks

    I wouldn't go any tighter than .004/.005 on an air cooled trike. Too many are too tight; And make sure that thing is jetted nice and fat to start with.

    I'd relieve the exhaust bridge if it has one also.....
