rjjammer Posted July 19, 2017 Share #1 Posted July 19, 2017 HI all I am back after an extended absence. I was so busy that time just slipped by. I recently. took the 86 out of storage to ride. I did cleaning and normal oil changes and stuff but it's turned into a project and I have been working on it ever since. At first it wouldn't run , finally took the carbs off and found the pilot jets in the block plugged on three of the carbs. I cleaned then all up new block gaskets and reassembled. It ran on all four and revs but it smokes white, a lot when revved up. Smells real rich. The diaphragms are good, I already have the needle shims from sky doc. I checked the compression and all cylinders are all within specs at between 180 and 184 with the throttle wide open. So I took the carbs back off and opened them up and double checked them looking for errors. Nope all was put together right reassembled and same thing. Smoke! I re sync'd again still no improvement. thinking maybe I messed up the jets I took off the carbs again and started checking the carb jet numbers and the placement. I found that not all the carbs have the same jets! I have owned this bike since 2000 and have the carbs off several times but I never gave it a thought to check the numbers! Now what do I do? Only one carb has the jets that the repair manual says the 86 is supposed the have. main jet 125 pilot 1 and 2 #80 and the other 37.5? My second question is the white smoke is new but the carbs haven't changed? Where do I look? Any help from the experts here would be greatly appreciated.

bongobobny Posted July 19, 2017 Share #2 Posted July 19, 2017 Is it white smoke (possible moisture in the mix) or bluish smoke (oil)?? Link to comment Share on other sites More sharing options...
BlueSky Posted July 19, 2017 Share #3 Posted July 19, 2017 How old is the gas in the tank? Could it have water in the gas? White smoke is usually caused by water. Link to comment Share on other sites More sharing options...

luvmy40 Posted July 19, 2017 Share #5 Posted July 19, 2017 does the smoke smell "sweet"? Possible head gasket issue? Link to comment Share on other sites More sharing options...
