Before you roll over the engine to get the engine in top dead center, pull the spark plugs. If you don't, you'll be fighting compression in the cylinder. Great video. 👍

I found the square end of the valve adjustment is the same size as a Robertson screw, so I put a screw in a knob of wood to use as a homemade adjuster tool. Great video, and I don’t even have a 250 Virago.

That's a great tip. I struggled trying to find a wrench to fit it and settled with pliers, which is very fiddly of course. I'll keep it in mind.

Thanks for posting this video. I was able to adjust the valves on my 2014 XV250. By mistake I used the inches spec on the feeler gauges for the first cylinder. I was wondering why the gap was so big. I ended up doing the first cylinder twice. You live you learn! Other than that all else went well. Cheers!

Great video. Keep it up. You are very good at making this kind of content.

Thanks bud. Went to go adjust my valves since I couldn’t go above 50mph. Just bought it, thought adjustment was just whack. Was getting good spark etc both sides. Pistons both moving. Turns out the first cylinder timing sprocket sheared off and tried to get sucked down into the engine! I only had one cylinder! So in theory your video saved me a big headache that is now the dealerships headache until it’s ready for me for real this time, Altho I just got my license yesterday and I’m sad I can’t ride it to work in this pretty weather! I can’t believe it ran at all let alone to 50mph with a loose chain and only one cylinder!

Yes. I think 3 owners. The last lady had it for 2 years and sold it. I bet she had that problem that whole time. The dealership never took it above 2nd gear so they didn’t notice the power drop, rode it all day yesterday trying to find why it wouldn’t accelerate above 3rd. 4th and 5th were basically useless. Then took off that timing chain cover off and bam. It’s was sheared right off with the bolt sitting on top of it.

Thank you so much for this video! I managed to adjust my valves following this and now the bike is soooo much happier! Great work putting this together man, looking forward to future maintenance uploads for the XV250 👍🏽

Thank you for making this video. Your thorough explanation and close-up camera work made it easy to follow. I searched for this video because a commenter on another video said you had to remove the engine on this motorcycle in order to adjust the valves 🙄. I'm considering buying one of these sometime next year, so I'm doing research right now. Overall, has it been easy to maintain and reliable to own, and do you recommend this bike?

Glad you enjoyed it! I made this video since there seems to be very little competent documentation or how-to material online despite this bike being fairly common. There is also no real enthusiast community or active forum for it which is a shame since it's really a fantastic bike. They made it since 1988 and changed almost nothing since then. A Chinese company has a 1 to 1 knockoff of it as well. As such, OEM or dubious Chinese replacement parts are everywhere. Aftermarket accessories are mostly limited to cheap Chinese parts though. Mine has been steady reliable aside from the usual carbureted bike problems. Maintenance is generally easy due to the simple and thoughtful 1980s design. I find it to be highway capable and a joy to rip around town. Everyone I know loves the way it looks and never believes that it's a 250 unless they are already familiar with the xv250.

The service manual mentions doing it at the first 3000 miles, and then every 6000 miles after that. It becomes a fairly quick job by the second time you do it.

When you take the timing caps off the crankshaft, is there any fluid that you should have to worry about leaking out on you. Just checking cause I wasn't sure if the oil flowed through there.

​@helloish12321 thanks for your response and one more question please. After you completed the adjustment, did you have any tapping or ticking come from your valves afterwards. Because I do. Im just curious if this is something to be concerned about or if it's the valves just needing to wear into the new adjustment. Prior to the adjustment the engine was very smooth sounding with no ticking whatsoever, so its now working on my nerves making me worry a bit. But i figured it was needed, the bike has 7,000 miles on it and the first tank I ran through it since owning it only got 135 miles.

@@CrazyPalidin57 the valves should have a slight tap noise. You should definitely hear them but it should be soft. If it's a loud noise and enough to give you concern then I would open it back up and recheck clearances. Make sure to remove your cam sprocket covers as well to verify you are at TDC on compression stroke for all adjustments and measurements.

Make sure the tires look good and are at pressure. Mine had a ton of carb issues when I got it but you might get lucky. Check/change the brake fluid since it's probably original. Make sure the chain is tight and slap some gear oil on the chain. Basic old bike stuff. How hot is it where you live? I noticed mine shifts much better with mobil 1 50 weight v twin oil in the spring/summer. The service manual has a chart for the recommended oil viscosity vs ambient temp. But the chart tops off at 70°f. So the recommended spec of 20w-40 probably isn't good at the 95° I ride in some days lol.

Did you get this ticking noise after attempting a valve adjustment or just over time? Has an adjustment ever been performed? My bike has some slight valve noise even with properly adjusted valves. I can get my ear right up to the engine head and tell what's going on just from sound, but it's just a subtle normal valve noise. If you want you can upload a video as private and link me to it in a reply

once you align up exhuast do you leave it there for the input or do you turn it again and just use the TDC for the intake?

@helloish12321

With the piston at top dead center on the compression stroke both the intake and exhaust valves will be closed. That's why it's important to verify top dead center by checking the mark on the cam sprocket. Line that cam mark up and then adjust the valves to spec. You only need to rotate the engine again when you go to do the other cylinder.

How many miles are on the bike and did you get it used? Are you absolutely certain it is oil? Check a few things. A stuck carb float or a float height being set too high can cause gas to flood into the engine even when the bike is just parked. My bike had this issue when I got it so the plugs were wet and it never wanted to start. Too high would also cause a rich condition which could make it buck. Smell the plugs. Let it sit over night and take the plugs out in the morning and turn the motor over with the starter. If gas flies out of the spark plug holes then you have a float issue. Also ensure that your oil level is set properly. Hold the bike vertically, not on the kick stand. With the bike completely verticle make sure the oil line is half way up the sight glass. If you measure oil level while on the stand then you massively overfill it and that oil has to go somewhere If both of those check out, do a compression test and make sure your piston rings are good. The valve covers are very simple and shouldnt be leaking into the spark plug just because of how everything is arranged. Whatever is on the plugs is coming from inside the motor.

Sorry, I know. I tried but the camera absolutely would not focus on it so I cut it out. When you do it yourself it will make sense as long as you know what the shapes are for each cylinder. You should also take the cam sprocket covers off and verify tdc on the sprocket marks to ensure you are on compression stroke and that the valves are unloaded. Doing this, it isn't even necessary to see the marks on the stator. If the motor is in time mechanically, the cam mark and crank marks will be lined up at the same time. I should have mentioned this in the video though.
