..lol..i like it...keeps me in high revs...

 HA! Thats usually an air idle adjustment,If you don't have an air leak or fuel supply problem      

[thebatman]

so i guess its back to square 1..

[wordslinger]

...dang...where's the second square...

[thebatman]

i know thats right..     wonder that myself..

[art]

 Ha! don't worry just keep an eye on that plug!

[thebatman]

well.....i have vaccum..     took tank back off this a.m..flushed it out(filter had sedement already)..cleaned petcock, FINALLY got vaccum back..didnt push it.   put all together, AND added my first dose of seafoam to gas tank and oil tank..      will do a quick chop to check plug..thinking of putting a shim in needle today..(with rereading/guidance from you all. )         also gonna throw in 5.7s, think id rather be to low as to high..   least rpms will stay put till i can get some 6s..

 Cool    Don't you feel better allready    With your porting you may be moveing more air so plug chops deffinetly

[thebatman]

well i ASSUME the vaccum correct..when i pulled on vaccum, could hear diaphram going up and down..when blow into fuel, its blocked..soooooo, i assume anyway.   hadnt started it yet............i need to port the intake since im to busted these days to order nice ones..    maybe porting intake/ported reed cage also w/a shim in needle...maybe thatll help some, idk... hoping the vaccum helps the takeoff issue.... thats driving me absolutely nuts there now......

ok check this out...plz.....this has happened numerous times..when i FIRST start her up(warmed just a min),and take off she is almost there..take off better, accel better, top better..BUUUUUT..when i take a short ride and shut it off(store,chops,etc.) and start it back, (still warm anyway),the take off is worse..up to 20mph/30km take off sh** slow/sluggish then hits and gone...even put in 5.7s today(liking these sum,hills rpm better,top great,rpms better )....i have experianced this tho with multiple weights....start up,go, better...short ride, shut off, start up,go worse up to 20mph

Let me comment here for the first time now since I am an old two stroke guy.  It sounds to me like you've gotten it real close to dialed in.  But, Bat man, 2 strokes always have run better when cold.  MUCH better.  That's why most racers went to water cooling long time ago and some street 2 strokes got water cooling later.  It's just the nature of the beast and you should expect a lot more pep when it's not fully warmed up.  Less when it is. 

Gotta work around that at all times with your tuning. 

[Hoolander2]

Let me be real clear.  You may already have it dialed in as good as can be.  Just gotta expect that drop off when warmed.

This is tru to some extent but think about it,when cold it is running for 10 points please!!!! diing diing diing!  RiTch! so a little clue as to what you need to do

  The wormer your motor gets the leaner it runs so to take advantage of it I would say go to even larger JETS!
