runs at idol, bogs with throttle

[Marcgraham27]

Hey guys, so im having some problems with my sj, it runs at idol but as soon as you hit the throttle it just bogs like crazy, it ran alright last time out but not great b/c im working on getting my carbs tuned in with my protec pipe. I was workin on it td and it backfired one time like crazy blowing out my waterbox, any ideas... i have already gone over the carbs and reeds with no luck.... any ideas?

So this happened from one time out to the next, suddenly?

 

[infamy]

is it bogging when you run it out of the water?

 

[Marcgraham27]

yes, it just happened suddenly, and yes its bogging out of water, the pump and crank all seem to turn smooth

Got it... ended up being the temp sensor grounding out.
