Hi, in nov i bought a 650 96 with 14000 km on the meter.
When i was riding home i already feeling hesitation an "moaning" sound when i gave full throttle. I have then removed the white spacer, put on a new exhaust, removed the snorkel from air cover. On a testrun i also noticed that the exhaust turned blue/yellow at the front part. On sweden models you donīt have to free the air screw, itīs already done. But the "moaning" sound still there, so tonight i checked the main jet and pilot jet. To my surprice the main jet was only 125, i even checked it with a magnifying glass, the pilot was 47.5. What size should i go to? 155? should i put the white spacer back again? Have anyone heard about 125 as main jet? Could this has been bad fore the engine? I should of course check the compression.
Rgds
