Hello,
I have a DT90 Suzuki that when you full or even 3/4 throttle it bogs down. It might go good for a minute but that's about it. If you turn to the right or left,hard, sometimes then it will power back up but not always. But once you straighten out again it looses it's power. Also if you rev the manual throttle (when the shifter throttle is boggging) it will take it out of the bog.
Is this wiring? Carb? Unsure where to go from here. I do have a repair manual but it's pretty greek as for all the diagrams and such?
Anything would be appreciated!
Thanks!

I'd start with the carbs and do a complete break down and cleaning. When you use the manual throttle the engine is in nuetral and isn't under a load anymore so it appears as if is running better. Make sure you are running fresh fuel, the tank is venting ok and try squeezing the primer bulb while running to see if it changes anything. Good luck.
