Apologies in advance for the early morning rant/cry
So, I went to change the stock exhaust last week to -*******- upon picking up the bike, the guy tells/warns me that it was hard to install the link pipe to the main exhaust because of the shape of it. I told him that the exhaust and link pipe are custom made for the honda CBF, so it sounded strange to me, however I guess you expect a good mechanic to have a bit of know how to bypass these problems… Well just under a week after having the exhaust silencer (which by the way sounds lovely). I found out this morning that there was a gap between the link pipe and exhaust, the gap was big enough to let exhaust gases leave. Pics below Here my dilemmas.
Should the mechanic fix this for free? although he warned me, but wtf, just do your job… or what?
Does this have a somehow easy fix?
While I find out a way to fix this, am I risking the bikes health somehow?
that depends, what brand of can is it?
if you supplied it and it’s not a precise fit then he probably did his bast to make it work but can’t do any better. taking it back to him will probably get this response from him.
can you tighten the clamp a bit? you might need to consider some gun gum or some sort of gasket to seal it.
I can’t see a gap there. Presumably tightening up the clamp doesn’t fix it? Generally, no, you’ll not wreck the bike, though you might get slightly less good fuel economy.
Which end can is that? It’s entirely likely that it’s an incompetent exhaust manufacturer rather than an incompetent mechanic.
This is the exhausthttp://www.scarichimoto.org/en/cbf-500/235-scarico-cbf-500.html. I’ve seen several bikes like mine with this pipe installed, no one reported problems. I did read quite a bit before buying it. As far as I know there should not be problems
No, it did not come with such a piece, and yes it pops with deceleration, although people on other forums where mentioning without worrying at all, and on a video I saw it does it too. I also changed the air filter to a K&N one
Seems you may need it tightened or a gasket. I’ve got a new exhaust on my CBF500 as well, but it is a complete system so I could get shot of the mild steel downpipes.
edit: Don’t try to squirt the RTV silicone in the gap, the pipe needs to be removed, silicone applied to the entire overlap and re-fitted. Wipe off any excess and leave to dry for a proper job.
Usually after a while the exhaust soot pack that hole and it seals. It’s usually gets better, now worse.
It may be worth removing it and putting some clear silicone sealant in there before putting it back on. This was the advice I was given by an aftermarket manufacturer and it’s always worked for me.
Well there is fine pieces of engineering coming out of Italy too, it’s not all metrosexuals and pasta sauce that come out of that country :P, plus they had good reviews… Anyway, perhaps for the next bike I’ll stick to the Germans, for now Lola will have to deal with it until it rots (hopefully in a long time from now).
