I have a '04 250r, mostly ride trails, and I'm a novice rider. I love the bike but I don't yet have the space, the experience, or the balls to open it up anywhere near its full potential for more than short bursts. So, I rarely open it up past 3/4 throttle.
When I ride for more than 20-30 minutes, it starts to bog out and stall at low rpm's. I'm thinking maybe the needle and jets are set for a faster rider and/or track use, and I'm just flooding the engine by not forcing enough fuel through the system.
Do you think I need to adjust the needle and replace with smaller jets? If yes, what do I adjust the needle to and what size jet should I get?
Or,do the jets & needle have nothing to do with it bogging out and stalling?
