More smoke from right side exhaust

[Oldskool83]

I fixed all my jetting, fixed all my electrical problems so now it runs very crisp and fires back up after I turn it off.

 

I noticed it smokes more on my right side silencer then my left.  I have everything set the same between carbs.  Not sure if one plug is not as new as the other one or if they would be a different issue.  Maybe its not even an issue and more so just an oiled up silencer.

 

Just wondering if there is anything to check I haven't tried already.  I am getting fuel to the carbs.  I have nice free flowing clear lines.

Checked to make sure crank seals are holding?

Could be a leaking right crank seal if smoke is real stinky from burning tranny fluid. Is tranny fluid low? If whiteish would be coolant leak.

No Tranny or coolant leads anyware on the bike. The exhaust only smells like premix oil and the stuff I run does not even smell.  It's not a lot more then other pipe just noticed it when testing my new CDI in driveway Saturday.  Entire motor was rebuilt and has maybe 3 hours on it. Carbs were cleaned twice in last 4 months and rebuilt once, and re-jetted twice also and both plugs look nearly identical.  I do not let the bike sit with fuel in the bowls either.  I may look at the air box tonight and see if there are any air leaks.  I know they are pieced together and wonder if that could cause it.

leak down.

I had the same issue and it turned out to be I had my carbs out of sync as soon as I bought me my syncing tool I made the final adjustments and bam perfect same amount of smoke on each side and it really made a difference in proformance.

[Oldskool83]

I noticed the air box is leaking at the seam where it is jointed together, brand new OEM one too.  I will need to remove it and gasket bond it all back together.  

 

After that I see if the carbs are still in sync...they were doing at a shop in oct.  Hard to believe in 3 hours they would be out of sync but I did have them appart 2 times for jetting.

 

Not sure why this bike requires more time working on it then riding it. I didn't buy it to be a mechanic.  More so up to be a rider.

[Jogon30]

Dude honestly you can kinda eye ball syncing but you really need the tool it will be surprised.

[Oldskool83]

Yeah I know dood...I have tools, a bunch of them lol.

[Oldskool83]

Noticed the right may have been opening later a tiny bit.  I cleaned carbs and sealed airbox connection while I was in there.  After 3 hours in the garage I am tired of working on it.  Maybe ride it sunday and see if it cleared up before I go farther.

Turned ful on to fire it up and gas leaked out of my carbs at the joints.  This is the 3rd set of gasket I have put in.  It seems every time I open carbs I need a new gasket.  Carbs never overflowed thru the tube but they will weep at the gasket seal at the fronts.  I guess stock carbs can soon go in the trash also.  Only other thing I noticed is my pipes are pretty oiled up at the packing connection.  It's been a year now so might be time to repack them.  Other thing I noticed was left head pipe has 3 holes in it.  Not hard but tiny pins holes.  I could see oil on my frame in a dumb area so that may be causing the  more smoke on 1 side issues.

 I repack my exhaust every season, sometimes more depending on how much i ride. Ive never had an issue with stock carbs doing what you have explained. I would surely weld the holes in your exhaust closed, IDK if its causing your problem or not but it cant be helping.

[Oldskool83]

I am going to hit them this week with welds.  Nothing is leaking at the pipe to silencer joint.  I have them band clamped very good with that rubber hose crap sold on ebay.  The clamps that came with were not strong nuff to clamp down but the one at lowes were.

 

I've even made sure I didn't have the bowls swaped.  I do not think its bowl related.  I have extra bowls and does not seem to matter what I do.  I think the problem is in the carb body but you'd think a gasket would take care of any flatness issues.  Right now its not leaking and didn't leak with a 2hr test with full bowl and fuel left in the on position. 

 

OEM gaskets leaked bad, just dripped out.

Vitos gaskets didn't leak bad, more so weeped over a few rides as the gasket seems to soak up with fuel.  Shame they couldn't of used a rubber gasket.

 

my 84 KX125 uses the same type of gasket to carb seal but they does not even leak if I have it off 20 times...prob been off 3 time total in 2 years.

I you want to try new carb bodies before before buying new carbs all together let me know. I have a complete set of carbs here that only need the tors delete i would ship you for peanuts. I have no use for them.
