Just thought I’d share this as it might help others

just done oil & oil filter change on my 4RT & like others struggled to get one of the front bolts to line up on the skid plate when refitting it

so I loosened the down tube bolts on the same side a little & also the long bolt that goes through the bottom see photos & it lined up

so I just tightened them all a little at a time until all were secure

hope this helps

 I changed to a csp before I ever rode my bike. Cut the rubber and siliconed in place. To give access to the side cover gasket withou removing the skid plate. Just installed longer bolts in the rear.
