Funny thing is the throttle side insert came out on the first try, with no WD at all. But it was just the scooter trash gods taking pity on me, cuz um, well, um, there was a little (ahem) PROBLEM on the clutch side (which I did first, thinking it would be easier). Had it soaking in WD overnight, tried putting the puller on and off about 100 times, then left the puller on under tension for about 3 hours, tried heat, got pissed and ended up ripping out the rubber core. Well then there's that little steel sleeve still in there. Totally trashed the end of the handlebar getting that out, literally broke the end of the handlebar up. Had little to lose at that point, so I just ground off what little remained of the thin section of handlebar. Looks like my new grip for that side can be trimmed a bit to fit up, but the TM o-ring closest to the end of the bar won"t fit into anything, it will just sit there. So, should I replace tha handlebar or use as is? Any problem with only the inside portion of the TM engaged on that side - any risk of it falling off? Opinions welcome, but please spare me the ******** award on this one, I feel bad enough already! Oh, and did I mention those little bar insert thingy's are a f**king pain in the ****** *** to remove from the bar?
