Me and MeanMachineMotofino got to work first we took out the blown motor and threw it hard as we could against the wall and swapped good motor over into the UM 150. We used the non egr head that came on the blown scooter as well as cam because it had lower miles. After engine was in place we set valves to .004 poured in fresh Kendall 10-40w oil cleaned carb again and while we was in the carb we drilled the main and pilot jets 1 size bigger and removed junky looking air box and took stock silencer off pushed the button and she came to life YES!!!!!!! It was quiet snappy for not even tuning on the carb went out for a test and hit 50mph GPS verified. Does this speed sound right? I think there is more in it...It launches awesome but soon as u hit 35 its a slow climb to 50 and thats only turning 7000 rpms.
