Title: How to reach rear exhaust screws to head with engine in frame?
Post by: MikeScoot on December 08, 2019, 02:50:30 AM
Even with the swing-arm off the screws into the head for the rear exhaust are un-Yamahaishly difficult to get at. I think I'll have to get an especially long 5mm hex set-up, but even then it will be very tricky doe to the flex through the hex shaft. There's no room for anything sturdier from what I can see.
Have I missed an easier way to do it?
Thanks

3/4" length of 5mm hex (Allen) key in a 5mm 1/4" drive socket, electrical tape to keep from separating. 1/4" drive universal joint and extensions to suit.

This is fresh in my mind as I just removed the rear cam chain tensioner adjustor from an '03 SV650S, which is conveniently located in a blind hole behind engine and frame. I have a set of 1/2" drive Allen key sockets, but the 5mm 'just wouldn't fit in there'.

Most motorcycle and car nuts and bolts can be handled with 1/4" or 1/2" drive socket sets and creative lash-ups.

On the stock exhaust remove the y-pipe first and the there is more room to get to them.  I must have used my 5mm socket drive bits.  I also have some hex 'ball-end' drivers that I highly recommend.  They let one get at allen screws from an angle.

Thanks fellas.

I ordered a extra-long (165mm) 5mm (ball end) last night. Also a bloke I work with is going to bring some other stuff in.

Happy right now 'cos I just ordered a used (but good) stock muffler/collectorbox assembly and already have a good 'y' piece and gasket ring fasteners. Should all bolt together nicely once the old stuff is off.

Ah, must get some if I can't make the long key work. Cheers.

My new super-long ball-ended hex key did the trick this arvo! Luckily none of the screws had been overtightened by baboons on steroids. Thanks for all input on the topic.
