Steve,

I'm not able to find Webra 1.2 dimensions on the web to compare with the OS1.2 FS I plan to use on the Mayhem.

Another gentleman on this thread says the dimensions probably limit one to inverted install.

Can you invision a OS 1.2 with standard muffler sitting sideways on this model.

I've finally gotten beyond worrying about hitting my head on landing, but inverted engines seem to have starting and setup problems that I'd rather not contend with.

A pix of your install would be great. I would appriciate your comments

Thanks Robin
