Setting the valves
« on: »
Hi all
       I am in the process of stripping my (new to me) MT01 to check all is well & tidy her up a little. I have her stripped enough to check / set the valves as per manual. I am looking for advice from those who have successfully carried out the procedure rather than conjecture from someone who has skimmed the manual if at all possible.
        All sets of valves are tighter than 0.004mm as per book & even but still look a little tight on a 'cold engine' to me what are your thoughts? P.S love the anti-backlash gear for the camshaft drives - that's quality engineering

On page 6 of this forum there is a thread about this, started by me.

Hi just did mine. Not sure what you mean by they seem a little tight. They are meant to have zero (or minimal) clearance at TDC. The pushrods have hydraulic lifters that take up the valve clearance. Any valve recession will result in 1 of the valves in the pair seeing increased valve clearance. Good design since valve clearance will only increase not decrease. I won't be doing mine again for quite some time.  Cheers

Not going to bother checking mine on whats been said on here if they don't reduce in clearance there's no point at 18000 miles

Its quite a faff to get to the little fella's, more of an interesting strip down for me - to see how its all put together. Its very well engineered - far better than my other bike BMW 1200GS. im loving the way they got it all to cram in given the height of the motor

The MT 01 is top quality in all respects.
The only thing that surprises me is that there is no monitoring or indication of the oil pressure at all. I thought the motor-computer was monitoring, but it turned out it wasn't.
Not a problem in real life, I guess. None of the Yamaha's I've encountered so far has had oil pressure monitoring or indication. Seems to work fine anyway.

I had twigged that the bike had no oil light & was trying to look for its pressure sensor, really odd that Yamaha choose not to fit one, may hark back to their 2 stroke heritage where no oil pressure was present?

They probably evaluated how often the oil pressure fails in an engine and found it to be an extremely rare occurence. One Yamaha we owned had a warning light for low oil level, which probably takes care of the rest of these problems.
I have installed a pressure sensor and a light on my bike because OCD. Goes out even before the first thump.

Hi Danmt
              it would be good to replicate your oil pressure sender / indicator solution - please tell me more

Here are some pictures and more:

The parts are from auto shops and speed shops, nothing special. I noted the part numbers, but the shops I bought from do not stock any more it seems. The oil pressure switch has "normal car engine" values, I was mostly interested in seeing the light go out. If it does all is probably well.
This was done a few years ago, I do not really remember the finer details. I have had zero problems with the installation, though.
If you look at the banjo coupling you will see a small aluminium rivet in the outlet. This is drilled with a small diameter drill (memory...) to be a restriction should the hose or any other part fail.
You have to go to the Warrior Manual to find the bolt that will be replaced with the banjo coupling. On pg 2-30 you can see it pointing almost straight up where the feed oil line to the filter is attached. You will only find the p/n for the bolt in the Warrior parts list on pg C4 item 26. You will need a similar bolt, only longer. I think the original is M8x12. It is extremely difficult to reach... I think I didn't use copper washers but instead fibre washers as they held the parts together while fiddling it in place.
Good Luck!

Great thanks, I will look for a small pressure switch that's available & suitable for the job given your experience
