Rear Engine Brackets

This is something I have been looking to do since I finished all the
other engine mounts. The top rear bracket and spacer was too wide
so I cut the welded nuts off the existing mounting point and
placed the right side bracket on the left side of the mounting point,
also shortening the aluminium spacer.

Moving to the lower mounts which I was going to leave off, But I read
somewhere online that these engines want to twist while running so
I have had in mind to get these lower mounts sorted. I made the brackets
but need to have them welded to the frame.

Rear Engine Mount

I decided to use the existing rear engine mounts
on the F2 frame but while the engine mount
lines up perfectly with the existing frame mount
on the left hand side the bolt holes do not line up.

A few 5mm thick steel mounts were fabricated and
welded with an aluminium spacer to fix the engine
to the frame. I just need to get a "Half Nut" and a
correct length bolt to finish the job.

Engine Frame Clearance

In order for the engine to clear the frame in all areas
it had to be lifted at the rear by approximately 7mm.

Next up is to make some top rear mounts brackets using the existing
mounting points.

Engine Mounts final

Front engine mounts welded into place and primer
coated to combat the surface rust building up in my garage.

So engine in and lined up. I had concerns about the swingarm
angle and the relation between the final drive and the swingarm
pivot point. The engine has ended up a little lower than desired
this will have to be a compromise.

The swingarm angle is set approximately at 12.5 degrees which
I read somewhere that it was a desirable number.

Engine Mounts

Next up is to get some new engine mounts welded
onto the frame. The earlier aircooled front engine
mounts are positioned the same as the later LC
ones but are the full width of the cases so the
existing mounts on the frame will have to be removed.

I plan to use 2 sets of mounts either side, an inner
and outer mount. The engine will bolt onto the inner
mount and that will in turn bolt to the outer mount
welded to the frame.

Mock up of the 3 engine mounting points to be used initially.
