Apparently I hadn't found all problems yet that arised after the test ride. I'm glad I found them now though or the next test ride probably wouldn't have gone so well. For pretty much all of the problems I had to buy these few things.

A few bolts of the front swingarms had come loose. I didn't put any Loctite on them just yet since I wasn't sure how tight they should be. I suddenly saw that there was some space inbetween, that's never good. So I loosened them all, put some Loctite inbetween and tightened them again. Should not come loose anymore now unless I really want to myself.

On the rear something also came loose, the 2 big nuts that keep the sprocket adapter stuck to the rear axle. Because of this the sprocket adapter was ale to move freely on the axle. I did already tighten this with blue Loctite inbetween but apparently that was not strong enough for the forces it has to endure. Also noticed that there was some play between the sprocket adapter and the axle. So I first used Loctite Quick Metal to fill up the space. Then I used red Loctite again to tighten the nuts. This should also not come loose anymore.

After that I continued again with the orange wire hoses. It's pretty hard with these thicker wires, especially the bends. It also still barely fits between the mounts.

On the side of the controller I already placed the RFI filters to reduce noise, also neccessary again for the road approval test at the RDW.

While I was busy with the wire hoses on the wires that go to the motor I suddenly discovered a very big problem. I noticed that there was some play on the connection points of the motor. I immediately took off the protective cover to see what was going on. To my surprise I saw that literally all of the nuts inside were loose. So the connections to the carbon brushes were also all loose. This is something that should never happen, If I would've pushed full power through the motor something would've certainly gone wrong. You can't really see it on the picture but really all of these nuts were loose.

The cause of this is very simple, it's because of the stiff orange wires that didn't have enough space during suspension travel of the rear swingarm. Will have to completely change this because like this there will be too much pressure on the connection points of the motor. I'm first trying to place the wires in a straighter line to the connection points and not all the way through the frame anymore. I will also tighten all of the nuts with Loctite so these hopefully never come loose again.

But ofcourse I couldn't easily reach it anymore so unfortunately I had to take the motor off the quad bike once again. Thankfully this is still pretty easy to do, I really only have to jack it up and remove the suspension. Can just take out the motor together with the motor plate after that.

Since I have the motor out now anyway I also checked if I could replace the temperature sensor with the one from Trailtech. That way I can be sure that I get to see the right temperature on my display. I'm just not really sure yet how I'm going to attach it and if I can even use this sensor this way. Will have to contact the supplier of the motor again for this.

I hope that these were the last few problems for now. It's not really fun to discover these things knowing that the quad bike is almost all finished. But on the other hand it's definately better to see it now than when it's too late.
