what do you guys set your fuel screws at on vipers...ive got an 02 and its getting stuck at 4000 rpm and slowly comes back to regular idle.. like 10-15 seconds to come back...

stock is 1-7/8 out from lightly seated,try 2 to 2-1/4...is the sled stock???
 
I just check mine last night and they are set to 2 turns out. If that doesnt fix it then i would consider going up one size on your pilot jet. With that bender single pipe you may need that extra bit of fuel.

yep....
 
When I rode mine for the first time yesterday ,I notice I had an occasional bog off the line and it also was high idling way more than normal with a warm engine. I think I need to take a look at my fuel screws too.

you have a bender 4x4 pipe on your viper?
 
Make sure you guys check that your pilot jets are clean. If you made some changes and it has a lean bog, fine then, adjust your fuel screws. But if you pulled it out from being stored and didn't clean your carbs, probably all thats wrong.

Right...
 
Could be.......I have not had to clean them since I have been using the Schaffer's Nutro fuel stabilzer. This stuff is WAY better than anything else on the market.


PS: the only reason I mentioned it on mine is... I have no idea if they were ever set properly after my pipes were pulled because I didn't do the work.
