yfz has no compression... leakdown test was good!?!?!?!?
ok... i was riding.. started loosing power... check compression 90lbs. after talking to the dealer they assured me it was probably just the rings even though the old ones looked fine. put it back together... 90lbs compression.
head/valves are fine, rings are fine... i put it together correct, timimg is good...
did a leakdown test an hour ago, held all the pressure we gave it... looked great... did another compression test at the dealer and they got between 65 - 80 on 2 different testers.
what is wrong? decompression seems to be working good...
dealer is lost... they gonna call yamaha tomorrow but we all know how smart they are...
