I dont know what else to do....

[Guest]

I finally got my bike running again carbs synced up and but i am blowing smoke like i turnned on my james bond smoke screen nooooooo good its white smoke and i got oil coming out the turnouts.... I can post a video tommorrow but im doin a compression test any ideas other than bad rings.... I did over fill the case just over the oil level window. Oooopppss but i am hoping that didnt kill my rings amd i have to take it all back apart again

What's a turnout?
Too much oil will cause it to smoke if it is above the oil ring on the piston.
Pull your spark plugs and see if it is oil or gas. Flat black is gas and shiny black is oil
If it's oil it is either too much oil or a broken ring.
Did you have the cylinder off?

Are the pipes on both sides smoking?

[mottacycle]

Smoke is white no black smoke and i rebuilt the head and rebuilt the carbs

[mottacycle]

I have mac 2 in1 turnouts installed on the bike

[mottacycle]

It also back fires out the pipes and out of number two carb.... What did i dooo!!!!😰

Yes both sides

[GS1150Pilot]

Was the bike sitting for a long time before you got it running?

Check if your petcock was left on "PR" or has just plain failed overfilling crankcase.

Check that the valve timing is correct according to the service manual, with reference to TDC, the arrow marks on the cams and the number of links between exhaust and inlet cams.

Three reasons for possible smoking. Overfill oil. Check you site glass and adjust as needed. Valve stem oil seals weeping and causing smoke on start up and down shifts. Ring issues. Not much history give. Are these new rings? If not and you are just getting the bike on the road, check compression. Pull plugs, open throttle all the way and crank the engine which the compression gauge is in place. If compression is low, put ONE teaspoon in the cylinder to be checked and try the compression reading again. If it increases quite a bit, the rings are in need of replacement. At this point, you will need to get a manual to determine the piston to bore clearance spec. Then you will need to measure piston diameter carefully using a micrometer and then measure the bore in a number of locations as specified in the manual. When you measure bore diameter, you will be checking not only clearance but to see if the bores are oval. If the piston to bore clearance exceeds spec OR the bores are oval, new oversize pistons are in order with the corresponding rings and you will need to find a bike machinist to bore/hone and do the work to within spec.

First step is checking compression. How many miles on the bike? Many air cooled bikes like the rings renewed at about 30K miles but this number can vary GREATLY.

Ground valves valve seats. New set of springs from forum member nessime.vitton valve stem seals valve clearence set at.004"
Veresah head gasket kit
Cleaned piston tops free of carbon
New valve cover gasket with new breather gasket
Rebuilt carbs with the o ring kit from forum source followed tutorial from ��cliff
Did break a float post yesterday when checkin float height booooo!!
122.5 main jet noticed when i was in there
Bench synced carbs then vacc synced on bike
Have new ex gaskets and mac 2 in 1 turnouts
Fiberglass resin seat pan led tail light.
Kenda cruisers front and back
Anyway thats all i can recall
I started this build almost a year and half ago hope that helps with more info��

[mottacycle]

Also 26 k on bike when i got it only put on maybe 15 miles😣

[mottacycle]

Goin to do another compression ✔ tonight when i get back from chico thanks for all the advice

I have checked cam plate position and timing three or four times now since the finish of the rebuild last jan
