:: Yamaha Virago XV Forums That Rock!!! XV750 Smoke out the exhaust pipes (SOLVED)

#1:  Smoke out the exhaust pipes (SOLVED) Author: Len Post Posted: Thu Sep 02, 2010 4:31 pm

Hi, just a quick background, the Virago range was never sold new in South Africa, recently a number of them have been imported by private companies and sold as what is locally known as 'grey imports' the bike dealership will not touch them and as such we have a shortage of spares and knowledge about the Virago's. I was quite excited when, after a lot of searching, I found this forum.

To the problem, the engine oil level was way to high as the sight glass was dirty and the level was not visible. The bike was ridden about 10km's and then started smoking out of both exhausts, the wife pulled over and we towed the bike home on a trailer. The oil was drained and the cover with the sight glass removed and cleaned, now the glass is clear and the oil level can be seen. I refilled the engine oil to the correct level, cleaned the spark plugs, cleaned the oil out of all the air rubber boots and replaced everything as it was. The bike seems to be running fine.

My question is this, could something else more serious have been damaged? The bike seems to be alright but I would hate for my wife to be out somewhere and the engine siezes or something like that, she is still a new rider (just over a year) and getting more confident, so I'd hate to set her back.

Naah, I doubt it. You got it out of there in plenty quick time. The question, however, is how did it get so full? When you emptied it, did it smell of gasoline? If so, you may have a petcock leak or carb issues that are allowing the raw gas to run down the cylinder walls and into the crankcase past the rings while the engine is off. Sticking float valves, the needle and seat, are one way this happens. Other than this, sounds like you've got things under control.

Also, keep an eye on your starter. A few posts have come in recently telling of finding the starter body filled with oil when it was taken off, the source being an overfilled crankcase. If it starts behaving badly or dragging, that might be why. Just something to watch for.

Thanks for the reply, I have been told these motors are very resilient so thought it was alright. The wife went to put in petrol and thought the oil was low, she put in an extra litre of oil, this was due to the oil level glass being dirty, now it is clean and the oil level is easily visible so it should not happen again. The petcock is working fine and the oil I drained out had no fuel in it.
