'almost' . . just like a 14mm spanner 'almost' fits a 13mm nut :-) Seriously, some aftermarket systems, particularly the "racier" ones, swing the pipes down well clear of the sump and therefore won't be critical in this area, whereas others are more "figure-hugging". Somewhere I have got a picture which shows the difference in the sump shape of the FZR/YZF motors, I'll try to find it. Whichever, there will be some hacking necessary to fit the 02 sensor and re-position the collector exit pipe for the GTS's low-slung silencer, so no aftermarket or other Yamaha system is going to fit without modifications, it's just a question of minimizing the work. >The only other thing that i can note about my exhaust is that it has 1 cap >screw at the lower point of each down pipe to set the cylinder mixtures , 4 >screws in total . A nice feature which all the aftermarket systems seem to overlook. SILLY PIPES: >http://www.sportbikes.dhs.org/index.cfm?fuseaction=displayit&Picture_ID=28101 Looks like about 10mm of rear suspension travel to me . . too daft for words (same goes for art in general, though) RUSTY PIPES: >[] the problem is indeed where the downpipes enter >the cat.

If it's like mine, the downpipes themselves are intact, but the collector inlets and pipe clamps will have suffered. No.2 and 3 clamps on mine have disappeared altogether. >I go for the quick option of a trip to store for exhaust putty and I've >applied that - we'll see if it works and keeps me going for the next >couple of weeks. In my experience the lifespan of exhaust putty repairs is measured in hours or even minutes, rather than weeks - just long enough to get you to the M.O.T. station and back! >she chickened out, so I'm taking my 12 year old son instead! Most likely this will make him a lifetime motorcyclist, are you sure you want this?! Have a good time and don't forget the "father and son" earplugs, even if your collector *doesn't* fall to pieces!
