I used to ride alot as a kid but i havent been on a bike for 25 years. So i bought a WR450F 05 did all the mods. My question is its all coming back but when i jump the bike seems to fall out from under me, I dont remember this happening to me when i was a kid. Am i not gripping enough with my legs or what. It seems that the bike has more gravity than me although i weigh 185.
