Hey guys, anyone else have problems with the 2 lower engine bolts coming loose on their KTMs? I’ve used blue loctite and even changed out the nuts for fresh ones. But for some reason they come just a bit loose and bike vibrates a lot.
Any thoughts?

I’m going to try different nuts again with red loctite.
When everything is tight, the bike feels good. But do you think it could be a sign something in the bottom end is out of balance?

just looking at the manuals torque specs...
Bracket screw is probably the through case bolts while engine brace is probably the head stays.
Today i Check the Bolts on my 150SX and they where completely loose.
I fix it with 60Nm and secure with Blue Loctite,
will check again After a few rides.
I also learned from KTMTalk that there is a steel bushing available from KTM that you can use protect engine case in swing arm area but that requires machining the engine cases to fit. https://www.motosport.com/oem-parts/part-number/75030010000
I have had several KTM's and have to deal with this problem many times. Nowadays I usually check every engine mounting bolt and swing arm bolt before I go riding

I took off my rear wheel and shock to get a good view at what was going on. Once I backed off the swingarm bolt, it had massive play! The case is doing exactly what is shown the the photo above. The shims fit perfect in the wear area.
I was able to fit a .2mm on both sides between the swingarm and the frame, also a .5mm on both sides between the swingarm and engine case! I got everything back together and the torque came muchhhhh easier, with less compressing of the frame.
Everything is to spec now, I'll see how it holds up this weekend!
