Been busy again today, I'm done cutting off parts of the frame now.

Upper engine mounts are gone as well now.

I will even out everything later on as I'll have to take everything apart anyway when the frame gets resprayed. Will be easier to reach those spots then.

Also still cut off the mount for the ignition coil. Wasn't really in the way off anything but it's no longer needed anyway.

Here's all the parts I cut off. The quad bike definately lost some weight already.

The battery tray might be placed back somewhere, still not sure if I want to keep using the lead acid battery for the 12V system. Thinking of getting 4 small 3.2V 10Ah lithium (LiFePo4) batteries and putting them in series. Much lighter, will last much longer and is even smaller with 4 of them together than the lead acid battery. But I will look into this later, the 12V wiring will be last on the list anyway.

Also checked again if the paper models fit well now. And they do.

Everything fits the way I want it now. There will just still be boxes around the batteries, hope there's enough space for these. Especially near the steering shaft, it'll be very tight there. For the rest I don't think I'll have any problems with it.
Maybe I still have to cut off a small piece of the front engine mounts since it's a pretty tight fit there as well. But I can only see if this is needed when the battery boxes are done.
