virustech Posted November 17, 2012 Report Share Posted November 17, 2012 Alright guys just to start out im gonna list my mods ect so there is no confusion then Ill tell ya what I did and what the problem is now Its a Stock motor .30 over Pro Circuit Pipes Boysen SS Reeds (New) Open Pod Air Filters Now just got the top end done brand new maybe 5 hours on it a metric shit ton of compression. I had a float Bowl sticking so figured id rebuild the carbs. So got all that done and also decided to put the boysen reeds in it while I had it apart. Get it all back together and im getting a metric shit ton of smoke at idle and even more at half throttle and so on. Not sure what changed I was gonna get it all back together and do some plug chops to make sure they jetting was good but the jets in it now seemed kinda small to me. Im just kinda trying to figure out what has changed and also I will list what I have done. main is a 240 seems kinda low to me Slow is a Stock 25 Got the needle set at the top now but went from mid up two because I was just trying to diagnose it. I used some carb cleaner checked every seal and boot and nothing no rev up at all. Im just out of options here. I have tried adjusting the carbs via the fuel air screw. and checked them for sync like 5 times there spot on. not sure what else to do from here. It seems that a 240 jet in illinois at 500ft above sea level seems kinda small was thinking of going to a 230 or even a 220 but with pipes and air filters seems kinda small to me. Any help would be awsome it ran fine until I rebuild the carbs and now its just smokes like hell out of both pipes. Quote Link to comment Share on other sites More sharing options...
Finch Posted November 17, 2012 Report Share Posted November 17, 2012 way to small of main should be alot bigger. what color is the smoke could be coolant leaking into the cyl from the head gasket, or tranny oil burning Quote Link to comment Share on other sites More sharing options...
virustech Posted November 17, 2012 Author Report Share Posted November 17, 2012 (edited) way to small of main should be alot bigger. what color is the smoke could be coolant leaking into the cyl from the head gasket, or tranny oil burning its blue and reaks of two stroke oil. and just changed the plugs out there wet its not antifreeze or gear oil but there wet as hell. Im kinda leaning toward a carb problem but wet plugs seems like the damn jets are too big I know there not but with the amount of smoke and bog im getting not sure. Im not losing any antifreeze or gear oil in the box it does not go down a bit. So its got me really confused. And it ran great before the carbs got rebuild. Ugh!!

maskmanLS6 Posted November 18, 2012 Report Share Posted November 18, 2012 Have you ridden it long enough to warm it up and blow it out? Quote Link to comment Share on other sites More sharing options...
virustech Posted November 18, 2012 Author Report Share Posted November 18, 2012 Have you ridden it long enough to warm it up and blow it out? oh yea for sure it smokes more when its warmed up than when its cold. just started it up when i had a friend over here to show him it was barely smoking at all then once it ran a little longer or idled I should say it started getting hot. The reason I have not taken it out for a ride is cuz its getting too hot when its idling so I was worried about it. I did take it around my yard and it got really really hot. I know that hot motors can mean and extremely rich condition because two strokes cool with the fuel not the oil like a 4 stroke. Or do I have that backwards ah well you get my point its running way way to hot! Was thinking about pulling the carbs back apart to check them out. To me it almost seems to be pulling air from the carb or something like that. I know its not the motor seals or head gasket. One thing I did notice is that it spit some coolant out of the overflow from the bottle. I dont know its just got me really stumped. Quote Link to comment Share on other sites More sharing options...
Paul M Posted November 18, 2012 Report Share Posted November 18, 2012 did you put the slides back into the same carbs they came out of ? Quote Link to comment Share on other sites More sharing options...
virustech Posted November 18, 2012 Author Report Share Posted November 18, 2012 (edited) did you put the slides back into the same carbs they came out of ? Good question I thought they were directional but they could be backwards I did take them apart and move the clip three times so. Wonder if just switching them would fix that>? Just out of curiosity why would it make a diffrence? I know that the slide has to go into that notch but I had them out on the table and gave them a good scrubbing so tom im gonna switch them and ill let ya know what happens Edited November 18, 2012 by virustech Quote Link to comment Share on other sites More sharing options...
So Cal Suspension Posted November 18, 2012 Report Share Posted November 18, 2012 Dude, you are WAY too lean... You should be in the 280-290 range with 27.5 pilots. You're running hot because you're running lean. Quote Link to comment Share on other sites More sharing options...

You're running hot because you're running lean. Yes. My girlfriends bike is 280 25 at sea level SS and stock port. With FMF pipes. I had 27.5 but the FMF didn't like them at all and it was to rich.

You're running hot because you're running lean. kk i know it needs bigger jets for sure but smoking first thing first once i get the smoke problem fixed rejet is coming but first i need to figure out why its smoking. got a jet kit on the way!! i knew it was either lean or rich causing the heat issues just could not remember what one it was so yes rejet plug chops ect. But there is something else here the smoke. let me get these carb slides switched and will see if that fixes the smoke them once my jets get here ill throw the 290 in and work backwards...

If no other fluids are burning, it's premix that is smoking. Jet it properly, try again. Quote Link to comment Share on other sites More sharing options...
Starwriter Posted November 18, 2012 Report Share Posted November 18, 2012 Make sure the cutaway on the bottom of the slide is facing the air filter. If you have them swapped side to side, the cutaway will be towards the motor when you line up the slide pin in the slot. Quote Link to comment Share on other sites More sharing options...
dave5.0 Posted November 18, 2012 Report Share Posted November 18, 2012 Don't just swap the slides, check to make sure the cutouts are facing the right way. Then throw a 280 main or so in it. I was in Illinois running pods and simar setup and was doin 320-330 mains. Had a few other tweeks too. Quote Link to comment Share on other sites More sharing options...

The "cutaway" is shown below. It should be towards the air filter. Both guide pin grooves go towards the middle, so if you swap them side for side, and line up the pin, you end up with the cutaway towards the motor.
