2015 YZ250F Crankcase Dowel Pins

Recommended Posts

I know the manual says only 2 dowels go into the crankcase halves, but you can easily fit the required 2 and there are 2 additional holes that will fit dowels.

Any harm in adding the two extra dowels? They are smaller in diameter like the ones for the head.

Why risk it. Those dowel holes may be there for assembly purposes. I would just put it back together just as it came apart.

No, there are always 2 dowels for good aacuarate location, no more, no less

First dowel provides positional location but obviously it can still rotate so the second dowel provides rotational location.

Anymore and they will 'fight' with each other

This is standard engineering 'jig & tool' best practice.
