hesitation off idle

[mikeydoodle]

im having trouble with my 03 viper. when i give on it off idle (around 3/4 to full throttle) it bogs down and the takes off. but when i rev it up till the clutch almost engages and full throttle it it has no bog. is this normal or is something out of adjustment?

If after you clean the carbs still have trouble do a search on fuel screws.

Also, make sure your throttle cable is adjusted properly.

Fatten out the fuel screws. Start with a half turn out, then go in 1/4 turns from there if needed. If your carb was dirty, it wouldn't idle.

thanks guys ill start by cleaning the carbs (never cleaned them) and then adjust them.

cleaned the carbs and still bogs. i put the choke on the first notch and the bog went away. richened idle screw to 2 turns from 1.5 and the bog almost cleared up. what would cause the lean condition? im running chevron 94 does this gas have ethanol in it and would the ethanol cause it to run lean enough to bog?

sounds like the carbs still need some cleaning. if you don't find anything maybe up a pilot size

Check your drive belt as well. A worn belt falls too far into the clutches and makes the sled pull out in "high" gear if that makes any sense??

What do you mean by "fall out"
