My son has had his buggy for a few months now and have had no problems. Finally got the chance to take him to a nearby riding area. It is really rocky and in the begining he had no problems. On our way back home he would hit a bump while off the gas like on a down hill section and the buggy kept stalling out. It would start right back up and run fine when on the gas but continued to stall out while off the gas and hitting bumps. I checked the uni air filter and it does look like it is time to be cleaned do u think this could be why it was stalling out. Any input would be great.

roaddog look at the intake around the bolts and see if the rubber has let loose from the metal and starting to leak.
i would look at that the rubber intake just don't seem to hold up well if riding rough terrain,they just never would hold up for me.

OK thank you i will check that out
