today i went for a ride as i started my ltr it took about 3 starts before it would acutely stay started usually it stays started on the first start which it's not to big of a concern to me because after i got it warmed up it started right up like always, but when i took off i noticed it was boging out at close to full throttle. the other day it did the same to me but stoped after i shut it off and restarted it so i figured maybe bad gas. i just got the whole top end rebuild about 6 months ago so im sure all that stuff should be just fine i really hope so, and i have no starting problems. but i while back i pulled out my swirl filter and it was pretty dirty, and i cleaned it out a lil. i ordered a new filter and o-ring for it now but just barley got it yesterday and have not put it in yet so im hoping maybe it will help along with a new spark plug, but if not dose anyone have any idea of what it could be? or have ever had this problem?
