Thanks. Wish I had come across that when I first started the whole process. Also wish tje manual explained that too. Maybe it's considered common knowledge to most but for someone never having dealt with anything having to do with TDC telling them just to look for the marks is really misleading.
After tearing my bike apart 4 times and going by trial and error I was about to throw in the towel but I got it done and feel pretty good about myself if I may say so.
Dude....congrats on doing the job yourself. Nothing beats the feeling of accomplishment.
Guess you're the new go-to-guy for valve issues.

Does the bike sound as it did before you did the adjustments or is it still sounding like a thousand mice typing away?
Im curious as to why you wanted to do the valve adjustment to begin with, your bike is a 2008, how many KM are on it? The M50 typically has this 'ticking' noise which is completely normal for the bike. My local dealer has advised that they have had almost no valve issues with the M50's and an adjustment typically does not need to be done until the 12,000km mark.

answer to the sound question. Yes my bike sounds just like it did before. You can hear the valves but only if u put ur ear next to the cylinders otherwise it's a real light ticking which u can barely hear when idling.
As to why I checked them. Because the manual says to. It's the 600 mile check. I bought the bike used but previous owner only put 192miles on it so it was time for it service when I got it I 600.
I trust the manual more than a dealer. I would have them inspected at the manufacturers intervals at least.
Good job doing it yourself, I've always taken my bikes in for that sort of thing, don't trust myself near the engine.
I cant seem to find this jpaige method, or maybe im just confused.... Im doing my valves real soon (for the first time) and want to be sure of everything. can someone post a link to it please?

Well first make sure u find TDC on both cylinders and then check the valve clearances. They might not need adjustment. That was my problem and had to tear my bike apart 4 times. You will need feelers to check the clearances.
If they do need adjustment you can use the jpaige method. All that is, is a mathematical method that tells you what the clearance is going to be just by knowing how much you've turned the adjustment screws. I have not done the calculations myself but I've used other's calculations and the results seem correct.
On the intake valves if you tighten the adjustment screws till they just touch the tappet and then loosen 1/4 turn it should give you a clearance of .004 in. On the exhaust loosen 1/2 a turn and that should give you .008.
I just don't see the need to do it so early this is not a HARLEY not bagging on them but come on guys this is a well built bike close to a Honda. IMHO and I have done the VA, it just does not need it, it is fun to do, and if you are certain you want it done, go ahead and do it yourself, we are here to help. Just set aside a good days work to do it depending on your mechanical ability. Good Luck.
Just ride the bike and enjoy. See your local mechanic when you really need to.
k guys. Noone said that they have to be adjusted but they do have to be inspected as per manual. That means they may be ok and they might not be. I can't say if mine needed to be because I screwed up when I was inspecting them and in the end had to adjust them. Just because the bike runs fine doesn't mean the valves are ok. If they are tight you won't here anything. Actually the tighter they are the quieter the bike. So there is no way of knowing until you inspect. If you're waiting till you have problems it might be too late. Maybe an experienced mechanic can tell just by the sound that's great for him but since I don't want to spend the money (because he'll still charge you) I'd rather do it myself.
As far as other bikes if they don't have hydraulic valves they will also need to be inspected/adjusted. Actually last I checked the Yamaha/V-star first valve inspection is at 400miles even lower than the M's
