I have a 2001 trx300ex I bought it not running about 1 month ago and cleaned carb and did a crab rebuild on it and I got it running but it doesn't drive right if you rev it to high it stalls itself I bought a new ignitoin coil and installed (kinda stupid) it ran a little bit better but nothing changed with the bogging. it has a old xcelorator exhaust by dg. with stock main jets I'm waiting to do these till I get it running better. I'm thinking it may be the DIAPHRAGM SET, PUMP but I don't know for sure because there not many videos or posts about them. anyone got any ideas?
