I just had my cylinder re niked, new rings, and piston and am ready to put the motor back together. I have an 86 500 and in the factory service manual the standard clearance between the piston and cylinder is .002-.003. I measured my clearance to be .005 by slipping a feeler gauge between the piston and cylinder. I've built a few motors and this seems a bit loose to me. The shop I bought the parts from said it's normal and to run it but I'd like some opinions. Thanks.
