Nightmare Posted June 25, 2014 Report Share Posted June 25, 2014 290 and 27.5 sound about right. I'm at 5000 and that's pretty much what my wife's banshee was at with the same mods before we switched to rockets.

xjmav Posted June 25, 2014 Author Report Share Posted June 25, 2014 (edited) I'm going to try to pick up a set of 27.5 pilots today. How do you test if pilot is ok? Cleaned the 25 and shee is actually idling now. So that's a good start!

trickedcarbine Posted June 25, 2014 Report Share Posted June 25, 2014 You know if the pilot is good by how it runs with air screw adjustment. If it runs better with more then 2-2 1/2 turns out then you would wanna go down on pilot size. If it runs better with the air screw all the way in, you may need a richer pilot.

SlowerThanYou Posted June 26, 2014 Report Share Posted June 26, 2014 We run your same basic combination using Toomey's guidelines. Our cool head has 22cc domes & run 280 mains & 27.5 pilots. Our base altitude is 2300' & our Density altitude is 5000' - 7000'. We run 1/4 mile asphalt with this set-up & have been 92 mph with this tune-up. It's hard to go wrong with Toomey's T5 recommended tune-up. http://www.toomey.com/index.php?option=com_phocadownload&view=category&id=1&Itemid=10 Quote Link to comment Share on other sites More sharing options...
xjmav Posted June 26, 2014 Author Report Share Posted June 26, 2014 I got her to idle last night with 25 pilots, 1.5 turns on air screws. Just bought 27.5 pilots and 280 mains. 21 bucks for all four!
