i have a drx 90 air cooled and when my son takes off it goes fast and then when he lets off the gas and presses again it bogs down really bad. we tried changing jets going up and down and a few other things but nothing seems to work. |

Before you Changed Jets did you do a PLUG CHOP and Read the Plug to determine you need to Screw with the jets????
How is your needle Setting????
Did this Happen all of the Sudden or has this been an ongoing Problem???
Do you have Aftermarket Pipe??
How is the Air Filter????
Fuel Filter???
Air in the tires???
When you modded the motor,,,Exactly what else did you do....In other words.....I want to know EVERYTHING you have done to the Bike....and Be Weary,,,,,You cannot JET a bike on the Internet....
