tonk Posted July 31, 2010 Report Share Posted July 31, 2010 Tried to remove the baffle from my Akrapovic but the fecker is stuck fast. The allen bolt came out ok but that's it. I suppose it's been through zillions of heat cycles now and it's over a year since it was last out (with no bother). I'm reluctant to go postal on it because the baffle is only steel (in a titanium can) and there's not much to get a grip of. Any suggestions? There's no gap to get release oil in and nothing to hook on to. It's already looking a bit chewed just from my mole grip efforts. Should I be doing it with a hot exhaust instead? Is it too risky to tap it in a bit first with a nammer so I can clean the crust off the rim? Oo-er! Link to comment Share on other sites More sharing options...
speedy sie Posted July 31, 2010 Report Share Posted July 31, 2010 spray some wd40 in there to see if it will lossen up. Link to comment Share on other sites More sharing options...
vala Posted July 31, 2010 Report Share Posted July 31, 2010 this happened to a mate of mine on his r6 with an akrapovic exhaust. he whack a load of WD40 round it, let it do its thing for the night and apparently it was very easy to pull out the following day.

tonk Posted August 1, 2010 Author Report Share Posted August 1, 2010 Cheers guys, I know capillary action is an amazing thing but the fit is so snug I can't see how WD40 would penetrate. However I will give it a go tonight. Fingers crossed! Link to comment Share on other sites More sharing options...
Conica Posted August 1, 2010 Report Share Posted August 1, 2010 You'd be surprised at how well WD40 or GT85 will penetrate even the smallest crack, failing that just twat it with a hammer Link to comment Share on other sites More sharing options...
tonk Posted August 1, 2010 Author Report Share Posted August 1, 2010 get something deeper down inside and hook it out? its worked for me with the baffle in my fuel zorst It's had a good soaking in wd40 now, will try getting it out tomorrow. Would need something like a spring-puller as you suggest, so long as the inside lip of the tube doesn't fold. Can you buy spares if I totally fuck it?

Leighio Posted August 1, 2010 Report Share Posted August 1, 2010 WD or the GT way shouldbe fine if not hold a hammer one side and twat it with another one the other and re-spray again and twat it a little more. Soot builds up and locks the buggers in place. Link to comment Share on other sites More sharing options...

MonkeyJim Posted August 2, 2010 Report Share Posted August 2, 2010 Broom handle down the middle, bosh it on the end. Aim it at your mate for extra amusement. yep, this was the winning technique for me. Baffle got stuck and wouldn't budge, attempting to pull it out wasn't working. So I took the can off and knocked it out from the other end I very rarely fit the baffle but when I do I give it a smear of copperslip around the flange Link to comment Share on other sites More sharing options...
porter_jamie Posted August 2, 2010 Report Share Posted August 2, 2010 *snigger* what he said. when i worked in chassis engineering it was a inuendo nightmare. flanges, gussets, nipples, shafts, rear bushes worn, orifice, Particularly funny if the supervisor was female, try and stick as many in as poss, as it were.

tonk Posted August 2, 2010 Author Report Share Posted August 2, 2010 Failed miserably. I will have to destroy it to remove it, the flangey bit is too thin to withstand any more battering or tugging. Everything else is moving, including the bike, except the baffle. Will have to source a spare first though - who duzzem? Link to comment Share on other sites More sharing options...

tonk Posted August 9, 2010 Author Report Share Posted August 9, 2010 Finally got it out! I took the end can off, planning to knock it out form the other side with a broom handle but there's a short curved link-pipe, held on by springs. Also stuck fast. No straight line for the broom handle. Hmm. Long story short, got some mild steel rod, cut a slanty notch in it, hooked it onto the end of the baffle and yucked it out. The WD40 had penetrated but there was a 5p piece size patch where the stainless baffle had stuck to the titanium, almost like it was welded. Oh and I destroyed the threaded blob on the baffle so it will never fix back in again. Will have to find a nut and bolt. Good grief what a noise! Trouser tentage! Really deep and rich. Had a quick run and there's a definite flat spot about 2,500 rpm but it fairly leaps forward from 6,000. I'll have to put it back in so the fuelling is right (can't justify a power commander) but I'll enjoy it for a couple of days more... Link to comment Share on other sites More sharing options...
deviant Posted August 10, 2010 Report Share Posted August 10, 2010 Aim it at your mate for extra amusement. Well yes, the dB killer on your VFR certainly wasn't stuck in any way when you fired it out of the can at my bike at Cadwell Link to comment Share on other sites More sharing options...
banoffee Posted August 11, 2010 Report Share Posted August 11, 2010 good that it's sorted. hindsight is a wonderful thing so I usually take the baffle out when the can is new and give both surfaces a polish. then, if I'm feeling naughty cut the baffle length down and refit so a> it looks standard but sounds fruity and b> piece of pish to remove with my trust spring puller in future. braaaap.
