Hi all, having bought an nsr mc16 a year or two ago that was sold to me as fully ready to ride i soon found out it was not, it then got thrown to the back of the garage and I bought another 250 stroker fully restored.
I've now started to turn my attention to the nsr, thoughts were to do a top end rebuild and tidy it up, carbs fully rebuilt and vapor blasted next job barrels off, socket set in hand exhausts off only to have the exhausts come away from the barrels by just removing the springs, the collars bolted to the barrels appear to be serving no purpose in holding the exhaust to the manifold is this correct or should the exhausts have a flange on them to allow the collars to do their job. the parts manual is not that clear to show the detail, however having searched ebay for second hand ones to view the pictures some are showing approx 10mm flange fitted 3-4mm from the manifold end .

Any clarification would be greatly appreciated.

Thanks in advance
Brian

Sounds like you may have aftermarket exhausts fitted, ie some form of performance system, as you mention that they are just held on by springs, this is the normal procedure for aftermarket systems such as jha, tyga, jollymoto, and a host of others, they simply push over the collars, supplied with the pipes, and are secured by the springs. You will need some sealant to get them to seal reasonably. If your'e not worried about originality, leave them on,a lot of people would give their high teeth for a set of aftermarket pipes for an mc16. Good luck with it.

I have a set of race pipes that exit up the right side of the bike, they are just held back to the collar with springs. Original exhausts can be bought off auction sites for about £150 but like Les says, leave them on, it makes the bike a bit different to everyone else's.
Is yours a red or a blue one?

Hi all,

Thanks for the replies greatly appreciated, Regarding aftermarket exhausts that's were I'm baffled, no joke intended they appear looking at photos of others to be original items including the end cans, even honda stamp/part No on the end cans. when I unbolted the collars after the exhausts had literally fallen off I expected to find flanges that had maybe broken away from the exhaust, however their wasn't even tack welds visible on the pipes. Colour scheme by the way is the red one in answer to dazsegger. Thought just popped to mind when took them off found no exhaust gaskets and silicone sealant blathered around, just thought it was another bodge done prior to me getting it.

Regards
Brian
