Another M42 Test Drive Video


Recommended Posts

How is it compared to a carbed M10? And is that an unusual amout of engine movement?

Apparently, that's a normal amount of engine movement. However, I'm going to do the mlytle-approved method of pinching the driver's side engine mount's limiter to keep the movement down to a minimum. I will likely need to mess with the exhaust, too.


The M42 is a lot more civilized than a carb'd M10. DOHC, EFI and distributorless ignition make it really smooth. Some don't agree that it's worth the work for only 136hp, but I really like the reliability (assuming you don't get a used engine with an overheating problem) and the efficiency. 136hp may not seem like much, but it's more than most people have in their M10s.

Clay, thanks for posting the videos.  My M42 will be going in soon.  As I watched your videos I was concerned about the movement also.  I have been thinking that the top radiator hose will need to have some room to move so that it won't eventually rip the plastic neck off the radiator or come off itself.  What are your thoughts on that?


I am not following you on pinching the driver's side mount limiter, mine does not have any such thing that I can see.  If you do it could you post some pictures of what you did or post on your blog.  It would be a big heip to me and may be other M42ers out there.
