gcautosports Posted March 26, 2016 Author Report Share Posted March 26, 2016 May want to fatten your pilot jets. If your saying there is an 1/8 - 3/8 bog than its not your main jet. Start with the pilot and make sure your air screw is adjusted right..Sorry thats what i meant thanks!Also what do you think about the picture of the plug chop why might it have done that?

bluebanshee98 Posted March 26, 2016 Report Share Posted March 26, 2016 I've done plug chops only up to 4th gear pined for a couple seconds. Did 2 runs and the reading on the plug was fine. If you have the room to do 6th gear then go for it but people limited on space you can do 4th gear Quote Link to comment Share on other sites More sharing options...

Strm Trpr Posted April 1, 2016 Report Share Posted April 1, 2016 I have fmf gold series K&N pods with outerwear 27.5 pilot 290 main Needle in 4th position No leaks Compression is 112psi with snap on tester 3700 elevation and its 54°F Air idle screw is at 2 turns out There's no way you need 30 pilots for this set-up at 3700 ft. You're 2 turns out on you air screws. If you needed 30 pilots you'd be under 1 turn out. What are you mixing your fuel with and what's your mixing ratio?

gcautosports Posted April 1, 2016 Author Report Share Posted April 1, 2016 (edited) There's no way you need 30 pilots for this set-up at 3700 ft. You're 2 turns out on you air screws. If you needed 30 pilots you'd be under 1 turn out. What are you mixing your fuel with and what's your mixing ratio? 32:1 lucas super synthetic (for now) klotz on the way Also it was 2 turns out at the moment of the plug chop which was looked lean Edited April 1, 2016 by gcautosports Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted April 1, 2016 Report Share Posted April 1, 2016 Is it hard to start when cold? If your pilot is lean it should be lazy off idle when you snap the throttle open. 32:1 is rich for today's oil. I've been running YamaLube 2R for 20+ yrs at 40:1 and never a lubrication failure. Plus 16oz of oil to 5 gals is exactly 40:1. I ran my current mods at sea level at Pismo with 30 pilots, clip in 4th groove and 310 mains. Bottom end was lazy as fuck. Moved clips to middle groove and man what a huge difference. My recommendation to you is the following. Mix fuel 40:1. << this means 40 parts of fuel to 1 part oil. You're essentially richening your fuel to air ratio and making your jets bigger. Sync carbs with FAST Sync tool at idle and 5000 rpm. Set idle to 1500 rpms. Turn your air screws to 1.5 turns out. 27.5 pilots 290 mains To do a proper plug chop you need a fresh set of plugs and a 13/16 wrench. Warm motor up fully with old plugs. Switch to new plugs and put old plugs in pocket. Run motor WFO to the top of each gear and when you get to 6th, hold it for a couple seconds, then simultaneously pull clutch lever and kill motor. Stop safely out of the way. Pull plugs and put old ones back in. Go to your work bench and cut the entire threaded portion off your new plugs. You want a 2mm thick brown combustion ring of smoke around the base of the white ceramic. Quote Link to comment Share on other sites More sharing options...

It is unless i pull the choke then on the 2nd kickAnd when im crusing then snap the throttle it bogs a bit then rips and keeps ripping with no bogs...maybe it just hates it when i handle it like a pussy..who knows Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted April 1, 2016 Report Share Posted April 1, 2016 If it bogs it needs fuel. Turn your air screws in 1/4 turn at a time until that bog goes away. Quote Link to comment Share on other sites More sharing options...
gcautosports Posted April 10, 2016 Author Report Share Posted April 10, 2016 So this is the plug chop with 30 pilot jet what the HELL is going on!? Also i changed my air idle screw to 1.5 turns Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted April 10, 2016 Report Share Posted April 10, 2016 Plug chops are done WOT in every gear and hold 6th for a sec or two. Simultaneously pull clutch and kill motor. Safely stop and swap plugs. This is a very safe and slightly rich motor here. http://bansheehq.com/forums/index.php?/topic/186085-plugs/#entry1794800 Quote Link to comment Share on other sites More sharing options...
