Hi everyone,

I am fairly new to motorcycling (I have been riding for about 6 months) and I have a Yamaha Scorpio.

I have started back at uni and am on a pretty tight budget now. I am keen to start doing my own services, both because of cost and it's something I think I'll enjoy doing.

I have read through the owners manual and everything seems pretty straight forward and easy to do. The only thing that looks like it will be a problem is checking/adjusting the valve clearences. The owners manual basically says that only a Yamaha dealer should do it.

I have been having a hard time finding any information on how to check the valves online. I'm normally pretty internet/research saavy but I have been able to find zip. Has anyone with a Scorpio managed to get their hands on a workshop manual or found anywhere with an online guide on how to check the clearences?

Any help or advice anyone has would be great.


Thanks in advance guys and gals!

Wont you still have warranty left on that?
You wont if you don't have it serviced.
Don't under estimate the value of a warranty.

Good point, however I bought the bike second hand so there isn't too much left on the wararnty.

Note the workshop manual in the link above, there's actually bugger all indonesia language in it. Event the part names and instructions were in English.

XT225 is same motor -- that said, they might've changed cams/valves for a more road-style power delivery, but would clearances change? It'll be the same method to pull everything apart and put it back together again at any rate.

So if you really need something in English, there'll be stacks of XT225 manuals floating around.

How so?
Most Yamaha road bikes have a 2yr warranty don't they?

1 year for Scorpios.

You'd know more than me about whether and how a warranty is passed on to subsequent purchasers.

The valve clearances (cold) for the Scorpio are:

Intake 0.05mm-0.10mm
Exhaust 0.10mm-0.15mm

I checked and adjusted mine yesterday. This is the first time I have done this and it was a fairly simple operation. I didn't have a suitable tool to remove the camshaft end cover so I just turned the motor over with the kick starter. It took many goes to get the top dead centre mark lined up doing it this way. After that it was pretty easy.

With the petrol tank off, there was plenty of room to remove the tappet covers and do the checking and adjusting. I didn't have to remove any other parts to get in there.

The intake was right in the middle of the range and the exhaust was at it's minimum, so I adjusted that to put it back in the middle of the range.

I had quite a maintenance day on my bike yesterday and it was very satisfying. I changed the oil and oil filter, cleaned the air filter, cleaned, oiled, and adjusted the chain and set the spark plug gap correctly.

My bike has 8000kms on the clock and it's nice to know for peace of mind that everything is OK.

The way I do it if I can't be bothered taking off the little cap on the end of the crankshaft to turn it over (mine's pretty munted from people trying to take it off with too-small screwdrivers), is I (with the bike on the centre stand of course) put the bike in 5th gear, then turn the rear wheel by hand. You can be quite precise.

Thanks,

Forgive me for reviving this old thread, anyone got the workshop manual for the Scorpio? The links seem to be dead now.

I found this page, but the links don't work

I have uploaded a copy of the workshop manual here
(http://homepages.paradise.net.nz/%7Ecloggy/Service_Manual_Yamaha_Scorpio_225.pdf)About 12Mb. The first couple of introductory pages are in Indonesian but the rest is in English.
