justinkk2005 Posted March 1, 2011 Report Share Posted March 1, 2011 Hey guys, I am currently debating on my next bang for the buck while not spending a lot. I was curious if it would be safe where my crank isn't welded to mill the head .20 (stock head) and advance the timing +4?

06specialedition Posted March 1, 2011 Report Share Posted March 1, 2011 Honestly it's the luck of the draw with crank failure. I've seen banshee's with pipes and filters have the crank come apart, and I've seen ported banshee's not have an issue. I had mine welded for the piece of mind, and IMO is well worth it. So to answer your question, do you "need" it welded.....probably not. Will you have issues....you never know until it's too late -Zach Quote Link to comment Share on other sites More sharing options...

I just added 350 main jets to my setup and i'm still running a little lean i do believe, slight bog on take off, hopefully this head milling and +4 timing may give me some more thump on bottom end.

flamingshee 666 Posted March 1, 2011 Report Share Posted March 1, 2011 i think u might be goin the wrong way with that.. 350 mains with the mods u have prob is a bit rich.. Quote Link to comment Share on other sites More sharing options...
justinkk2005 Posted March 1, 2011 Author Report Share Posted March 1, 2011 (edited) i think u might be goin the wrong way with that.. 350 mains with the mods u have prob is a bit rich.. I done 3 pulls 1st through 6th gear, the plug was dry with 340 mains. I am needing help with the bottom end though, currently 25 pilots but i'm giong to got to 27.5 to see if it fixes the problem. What do you recommend the needle being set on? Elevation: 800-2000ft Edited March 1, 2011 by justinkk2005 Quote Link to comment Share on other sites More sharing options...
crash&burn Posted March 1, 2011 Report Share Posted March 1, 2011 i think u might be goin the wrong way with that.. 350 mains with the mods u have prob is a bit rich.. I Was thinkin the same thing a bit rich..... mine was at 330 mains 27.5 pilots, with stock stroke, 17cc domes runnin 110 race fuel, 65mm bore, dune port, T5's, K&N Pods, VF2 reeds, and runnin about at sea leval, and the jetting was near perfect Quote Link to comment Share on other sites More sharing options...
crash&burn Posted March 1, 2011 Report Share Posted March 1, 2011 Have you done a leak down test yet maybe you have an air leak causing a lean condtion Quote Link to comment Share on other sites More sharing options...
justinkk2005 Posted March 1, 2011 Author Report Share Posted March 1, 2011 Have you done a leak down test yet maybe you have an air leak causing a lean condtion I just replaced the intake boots, got rid of the crappy boost bottle for a crossover tube, replaced the little clamp things, and the whole 9 yards. What is the best way to do plug chops? I mean I couldn't really tell much after those 3 pulls. I've saw on the jetting forum where people were posting their setups and some people had 370/380 mains with the same setup as me. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted March 1, 2011 Report Share Posted March 1, 2011 I have a similar setup as the OP on my trail Banshee. Head milled 0.020", +4 or 5 timing, T5s, K&N in box/no lid, 350 mains, but only 25 pilots, 300 ft elevation. That Banshee hasn't been beat by any other non-ported stock cylinder Banshee. It could use bigger pilots, and runs a little rich on top, but revs out clean and pulls good. It runs on pump gas. Quote Link to comment Share on other sites More sharing options...

Yea I would def. rather have it a bit rich than lean, I'd rather replace spark plugs than rings anyday. Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted March 1, 2011 Report Share Posted March 1, 2011 your riding between 800 and 2000ft? shit man.....your gonna need to do a jettin change between 800 and 2000. the hgiher in altitude you get the thinner the air is....meaning your pushing too much fuel at 2000 where you might have been perfect at 800. Try the 27.5 first. No 2-stroke motor is the same......but MOSTLY ALL of them perform way better with a 27.5 pilot when you put aftermarket pipes on. The plug chop goes like this........warm bike up on old plugs. Change out plugs and fire it up and run 1-6 gears wide open to the top end. Then pull the clutch in and kill the motor and coast to a stop. Then put in your old plugs....go home and chop the threads off of your test plugs. You want to see a ring approx. 2mm tall starting at the base of the spark-plug on the white insulator. And you want it to be a light milk choclate color. If its darker then its running rich and if its lighter colored then its running lean. Quote Link to comment Share on other sites More sharing options...

It sound healthy to you? I know I don't have a helmet on but I do usually wear one. Quote Link to comment Share on other sites More sharing options...
chevybanshee91 Posted March 2, 2011 Report Share Posted March 2, 2011 sounds decent to me.. jetting sounds about right maybe one size up if your a little lean.. im at 350 now with ported lid on air box and basically all the same mods.. tad lean myself. anticipatting warmer weather tho.

dirtydownunder Posted March 2, 2011 Report Share Posted March 2, 2011 probably not a good time to decide not to wear that helmet, seeing you usually do haha. if a car or dog or anything ran out, you'd be fucked. good times sounds ok, but you need a dry surface, cause its wet the wheels are spinning like crazy so there is less load on the engine. it does seem to bog down in a rush a bit when the revs drop.

What do you guys suggest for that? Idle - around 1/4 throttle it does bog down and sputters until you open it up. After you let off the fuel and stop for a idle, and then get back into it, it sputters a tad bit and then opens up. The pilot is 25, needle on 3rd position. Air screw is 1 1/2 turns out But back to the original question lol Shave the head .20 or .30? Thanks guys, You guys are a lot cooler than the guys on d-series.org lol (had a turbo honda, guys on there were dousches) Quote Link to comment Share on other sites More sharing options...
