  1. The new jets have really smoothed the bike out, engine sounds real sweet, sparkplug has perfect colour, mixture screw set at 1 turn out, Thanks ALL, Thanks Steve for your time.
  2. Nice that you've got it sorted Steve, fitting new jets this.evening, going for a good run in the morning so hopefiully thats it.Never had these problems.with the Dellorto, Copemechs right, the keihin is a pain in the a***.
  3. Interesting, most of the areas we ride are muddy slippy woods. Defenitly dont want the bike too snappy off stop need all the traction i can get, did have a good run on a 2011 290 with the dellorto on it , very smooth down low, if i was able to get the keihin that smooth i'd be a happy man.
  4. Thanks for that Steve Have ordered new jets, all going well should have them for the weekend. I know im too fussy, just dont like lean running 2strokes a bit of an OCD for sure.
  5. I'm old school, dont have a lot of money, but i'd rather spend money on a piston kit than bling, spendthrift, dont think so, just like me bike to be right, when your as bad as me.you dont be long putting the hours up on them, keep trying though.
  6. Hi 2 stroke 4 stroke , No roadracing background, just in the past i've been unlucky with 2 strokes, the first 2 secondhand 2strokes ended up needing pistons after a few months, so ok i change pistons on any bike i get , if that makes me a weirdo ,so what, i stand over any bike i sell on, what goes around ,comes around, nothin wrong with that, is there?
  7. Hi 0007, When i get a new bike i change piston and crankseals as part of its service, a good starting point i think when you dont know it past, been caught out before.i do know the mixture is adjustable for a reason, didnt think it would have to be set this far in, my fault i was comparing it to the settings on 2 other 290s, was alway.told it had to be between 1 and 1/34s, takin it for a good run at the weekend, Cheers...
  8. Thanks for all the advice, I know i should have left it as it was but i thought the mixture setting was masking a different problem, tried another carb off a 2013 his jetting was the same but his mixture screw was out 11/2 from stop, same bad running until i turned mix screw in, the sparkplug looked rich thats why i messed with the mixture in the first place, gonna leave it as is, and ride it and see what happens. Thanks again.
  9. Hi all, Have recently bought a 2012 290st, seemed to run ok when i looked at it. Got home and as you do gave it a service, i noticed that the fuel mixture screw was only half a turn out from stop,i adjusted out to 1 1/2 turns, bike would'nt idle properly revs would hang then drop and it would pink when under load. Thought it might be crankseals soo replaced them, still the same, stripped carb soaked it in carb cleaner, blew out all the channels set float height as splatshop , sealed inlet manifold reed block , bike still runs rough unless i turn mixture screw to 1/2 out, then it runs nice. The carb runs with 125main 45 pilot and second clip from bottom, am abit puzzled by this one anyone any ideas. Cheers
  10. I've heard a clutch with the rubbers gone before, this was a different noise altogether, thats why it took so long to find the problem, but atleast it sorted now.
  11. Thanks Copemech, Naichuff,Melba26, Heffergm, Dadof2 and last but not least Thats a five for all of your input , Melba26 you where close , it turned out to be the clutch rubbers, never thought they would cause such a knocking noise, lesson learned, thanks again for your help.
  12. Had that on a gasgas aswell, was one of the first things i checked, thanks for that.
  13. The knocking is from start up and builds with the revs.
  14. Not clutch rattle, bigend bearing was replaced, could a new bearing be faulty??
