That makes since alright. I'll try and get my hands on some more mains asap. Didn't get a chance to go play with it yesterday, got called into work so hopefully I'll give it another try during the week. Thanks again

holy shit stains 16:1 mix????that right there has seriously leaned out your air/fuel mix.do a 32:1 mix at least.the more oil the leaner the air/fuel mix.less oil the richer.what oil?klotz supertechniplate is the shit.r50 is a plug fouler.change ur ratio to 32:1,install bigger pilot.if that dont help,close the gap on spark plug slightly and see if that helps or makes worse.make sure the carbs are really synched good.the closing of the spark plug gap is a somewhat test to see if u have a weak ignition.is the black brain box to the tors on the left side frame disconnected?+4 timing might help too,but that and pilot is more for bottom but does have affect on midrange.seems odd changing all clips makes no difference.was it better or worse before u changed the needles themselves???? The reason for the 16:1 is the manual said to use it for the break in period. If i went 20:1 would that be a bit better while still playing on the safe side?? Could my problem be due to porting or should my shee run fine as is?? I can't seem to get Klots over here at the moment so I'm using Shell, its supposed to be the best available and all my mates use it with no problems. I haven't disconnnected the TORS but I'll try that also. The carb sync seem's to be spot on. I think it was worse before I changed the needles but I'm going to put the stock ones back in and double check.

Thanks for the help, I'll give another read through the links for jetting. She's the same warmed up. The reason I didn't try a plug chop is I was afraid of doning damage, I was trying to get a clean rev before doing that. I'll try the stock needles and see. I thought the ones in the kit might richen it up due to they being shorter than the origionals. Thanks again.

Hey there, sorry for not getting back to ya earlier. I gt a jet Kit on Monday, but as always the shop ordered toe wrong one so the only thing i could change were the mains, 280's to 340's. Synced the carbs, idle screw 1.5 out, it will rev out now but still boggs and bangs between 1/4 to about 1/2,+ or -. I am now thinking have i a bigger problem. I replaced the stock needles with the ones in the kik ( seem about 3-4mm shorter) and put the clip in the centre position. I have moved the clip to all positions both rich and lean and it seems to make little or no difference. Should my cylinders have been ported to match the +4mm stroker kit or should she still run away happy without porting?? Can anyone give me some info on porting 2 stroks as I;m new to them.

Sorry took so long to reply, Crazy busy since the holidays. I purchased a 4mm stroker kit,(crank, spacer plate, wisco pistons.) bolted it all up and like I said at the beginning it wouldn't run, she just kept bogging and missfiring. Anyhow In relation to your question's the spacer plate goes in under the head's and I have no leaks. New K&N filter fitted to modified air box, (Alot of holes drilled and the inside of the cover removed) My mains were 280's, Pilots 25's. Mix is currently 16:1 (Run in Mix according to manual) I purchased a jet kit which arrived the beginning of the week but was the wrong one, the only bigger size than what I had were 340's. I replaced the 280's with the 340's, replaced the needle's ( Mid clip position) and started it, not too smooth on idle, boggs at 1/4 to 1/2 then revs free??? (Just bogged previously, wouldn't rev out) tried needle height adjustment but no good. Have I bigger problems?? cabr sync is ok, idle screw 1.5. I don't know alot about 2 stroke and I'm now thinking is my problem due to porting or am i still lean? has anyone any info on porting?? Thanks in advance.

Ya the slides are back in the right carbs, I double checked yesterday, its about 4 degC here at the moment, nice and fresh. The only thing i did with the TORS was remove it when cleaning the carbs and checking the float height, i put it all back together and sync'ed the carbs again after, its a pain to do anything with that in place. I might remove it altogether later in the new year.

I was thinking the same, thanks for the info, I'll get some bigger jets in the new year, no store open for parts here in IRE until the 4th Jan. I'm using FNF fattys and a K&N filter. The filter is still in the box with the lid on, wonld ye recommmend removing the lid or the whole box?? the reason I left it on was we do alot of trail riding and its fairly muddy. Thanks for the help.

Hi all, I just rebuilt my motor over the Christmas break, and I'm hoping someone can help me in sorting out what jet's to use. The current setup is as follows: Carb: Main Jet 280. Pilot 25 (Stock) Needle clip on last position. Also V force reeds. Engine: New crank with +4mm Stroker, Cylinders overbored to 65mm with Wiseco pistons ans rings. My problem is when I open the throttle beyond 1/4 it boggs and starts banging and misfireing, I moved the clip on the needle down to the last and when reving the engine i pull out the choke, it definately made a small difference so I think i need bigger mains? does this seem correct?? what size do ye think I should begin with if my thinking is correct?? Would i also need to increase my pilot jet's?? it seems to tick over nice a smooth as it is with the stock 25's and run smooth to just beyond 1/4. The air screw is at approx 1.75 turns out. Any help would be greatly appreciated. Oh my elevitation is about 350 - 500ft above sea level and the current temp over here in IRE is between 4 and 10C.
