smokes on start up

Postby bndbelle » Thu Mar 29, 2012 6:33 pm



Hi all,
I bought my 95' 1500 last june with 103,000 miles on it. I changed the oil,filter and air filter when I first bought it. The other owner did not keep any records of service done to it. It runs smooth and never have problems starting it. The last few times when I started it there is a lot of smoke. It does seem to clear up as soon as I take the choke off. It never smokes while I'm driving. I average about 32 MPG in town and 34 MPG on the highway. I thought I should get better milage than that.I am thinking that it might be time to have the carbs rebuilt since I have no idea if that has ever been done. Anyone got any ideas ?
Thanks for any info.

How long do you leave the choke on for??

Startup smoke on these wings is commonly caused by old/bad valve guide seals. After being ridden and then parked, the oil that's remained in the valve cover area seeps into the cylinder(s) through the valve guides until the oil has drained back into the oil pan. The oil in the cylinder(s) is quickly burned up and exhausted upon startup.
Keep the rubber side down.

My 89 is cold natured and will puff a little after 30 seconds with full choke, but quickly goes away when choke is released. It don't use oil and the smell is rich fuel so I let it go. Fuel milage is consistantly mid 40's and with wife on back have seen up to 49mpg.

Not sure what type of oil you are using, but one good application of Marvel Mystery oil in the crankcase can work wonders on an engine as complicated as the wing. If you remove and drain the oil filter, then relace that much oil with MMO, and ride it a couple hundred miles while it's still cool weather could be the ticket. I doubt your cylinders/rings/pistons are worn. I just took the heads off my 83 standard with 69k miles to do the head gasket (one starting leaking). There is no ridge that I can measure, using a straight edge, feeler gage, and bright light to try and pick up a difference between the bore at the top of the cylinder and the bore 1 inch down. No wear. PO may not have changed oil as much as they should have and rings could be partially stuck. I don't think it is valve stem seals.....mine would be worse than yours for sure, and this ole '83 never smokes, as I ride it a little every couple of days.

Depending on how cold it is , I only keep it on for about 3 minutes before I start riding then I shut it off.

I am a true believer in Marvel Mystery oil. I have used 3 oz in my fuel tank when I filled up, but only twice since I've owned it. I wasn't sure about putting it in the oil, but I will sure try that now. I always have a bottle on the shelf.

L us know how that goes. It raised my compression....I blew a weak head gasket in the making within 500 miles of adding it. Boy was it running like a real machine...right up to the stop sign anyway. I couldn't believe the difference. But then take any car that has been sitting around, racking up 69k miles in 30 years, including many years with old school dino. Likely in the same boat as the bike, no way around it.
