RE: hyper 7 - super good ||| hyper .21 not so good
found the prob guys. there was dirt under the copper ring and when i screw the spark it didn't seal probably,,Also i can observe some dirt particles on the center of my piston should i go to my LHS to clean the whole engine for me or just unscrew the cooling head and clean the piston? lol i would love to go my lhs ,i wasn't doing so well with the guy that owns it lately, basically since i bought my h7 online for 250euro instead of giving 450 for a GS CL-1 that he sells .when he noticed that my engine was suffering from luck of compression , god he was so ironic with his words..anws hope i didn't get too boring:P
