Hey guys and girls’
I made a search, but I did find the right answer for my question
Will the right crankcase from a -05 fit my -03?
And if not. What’s the difference between them?
I found a new right crankcase for a -05 almost for free

The cases are machined as a set, and must be replaced as a set. To do anything elso could lead to trouble.

Try it and tell us how it works!

You should pay close attention to crankshaft and Transmission shaft end play!

I have search the internet and can’t find that there is any difference between -03 and -05?.
When I called my Yamaha dealer in Stockholm(Sweden) they sad that it’s not
The same part number. But it is probably the same!
Why don’t they have the same number if so?

I mean. Don’t want to buy any thing if don’t fit. The one that I found from a -05 is a about 170 $ and a new crankcase is a about 1660 $ in Sweden.
