Sent motor to full bore,engine has never been opened up before. Internal oil leak and I just got tired of it. A couple of question while I clean and replace stuff while motor is out. Are the mikuni diaphrams that much better then after market?I`ve heard it but it ran ok with after market,some times on hot days it seem to crank alittle before it started[may have been a tired engine.] Also I have a near new after market carbon seal,are the seadoo oem better? Any reply will help while I replace all fluid lines. Thanks
