I’m hoping someone can articulate and/or show how the de-cat mid pipe by Leo Vince is fitted to the bike. When I tried earlier, two issues occurred:
1) The shock absorbing bushing/washer/bolt thing didn’t go all the way into the eyelet of the frame where the cat was original mounted at. It got tighter and got stuck about half way in. It’s not cross-threaded and the thread pitch seems to be correct (identical to the original bolt that held the cat). Likely because the rubber bushing is basically holding two-sided screws with no real gripping point, I had hard time trying to screw that in or out. I might just have to chase the threads, but I want to see if I’m missing something obvious.
2) Even if the shock absorber is all the way in, it doesn’t look like the mid pipe will align/fit with the header and the eyelet of the frame if you were to put stack parts up as the instruction depicts. If I remove the shock absorber completely, the eyelets of the mid pipe and the frame seem to align perfectly. Again, I may be missing something obvious. Below is my understanding of how parts should stack up based on the instruction provided with the mid pipe.
Any observations, pictures or tricks will be much appreciated.
I’ve looked around and I found a thread about LV mid pipe fitting issue with KTM 690. Basically the OP there needed to loosen the header part, fit the entire exhaust parts and yank the mid pipe a little to put everting in place. I’m gonna try that, at least other than the yanking part.
As for the shock absorber fitting, I’m gonna try using mild thread lock or WD40 as a temporary lube plus see if I can chase/clean the threads on the frame side a little, but I wanna make sure I’m not misunderstanding the use/fitting of the absorber. Would be great if someone who has the decat pipe can chime in.
