07 CRF 450R bog at times / needs throttle to start

16Raptor

194 views

So my 07 CRF 450R recently decided it would bog a bit soon as I would come up to a jump. It would bog for couple seconds then all of a sudden the power would come  then when I would down shift to first gear pulling up to my truck it now stalls. I had the valves readjusted by the nearest Honda dealer for $600 three years ago and really only about 80 hours on vavle adjustment and I'm know perfestional rider but I'm decent. Now to get it to start I need to give it a bit of throttle. Typically I just pulled the choke three twisted and pull it to top dead center and one good kick she would start now I need to give it slight throttle to get it to fire up. Is this a carb problem or valve problem. Please note my next bike will be fuel injection I'm so &%$#@!in done with carburetors. Fuel injection rules &%$#@! carburetors!?once it's running it runs like a champ but at idle I need to keep giving it gas or it'll stall. I feel like it's a carburetor problem. I plan on selling the bike end of season as I'm buying a brand new fuel injection dirtbike this Christmas. Is there a fuel filter on this 07crf450r !

Either a gummed up pilot jet, or your valves are going back out of clearance. 

btw - there is no need to take it to a shop to shim your valves, there are loads of videos out there. Not that difficult and only takes about an hour or two your first time and saves loads of dough ?
