Putting my SB6R to bed for the winter so thought I'd give it a once over before she goes off to hibernate. I have got the bodywork off and discovered the following:

Exhaust - bad crack where the pipe splits back to 2. Suspect repairable but does anyone do a more "sporty" rear system?
Air filter - looks like just a lump of old foam roughly chopped out. Is there a proper service item or do I just wash this out as per owners handbook?
Radiator cap - has obviously been leaking. I guess it's a Suzuki item but couldn't find the right part number trawling on line parts diagrams. Anyone advise?
I'll drain and flush cooling system. Is it worth replacing hoses with a Samco kit given originals are now nearly 20 years old?
Finally will the engine start and run with a remote fuel tank in order to do the above?

Anything else recommended whilst she's naked so to speak.....

Many thanks for advice

to the last 2.
I've used a Samco kit on mine (SB6) but be prepared to cut them to fit.
Yes you can run it on a remote fuel tank, you'll be surprised how fast the fuel drops !!!

I don't think there's a sporty pipe as such, you can cut the silencers off and use aftermarket
Airbox foam - I think you can buy pipercross foam or look for a flat panel KnN type cut it to shape and silicon a frame to it

Exhaust - later ones were supported at the joint by a plate welded on. Aftermarket cans can readily be made to fit to the seat unit. The tricky bit is the bent "Y" piece connecting the cans to the downpipes, because you can't offer it up without the cans attached to the seat unit. But it can be done. A lighter exhaust, combined with lighter wheels, make the 6R a completely different bike.

Air filter - ITG will make you a proper one.

Rad cap is not sourced from Suzuki I'm afraid. Your only answer is to get a new neck made that will take a readily available cap.

It's well worth replacing the coolant hoses. Samco does a kit, of which the 2 bespoke hoses fit (fortunately), but many of the others do not, as Chuckie says.

I put my tank on a workmate and connect a longer hose to the pipe into the airbox.

Worth doing the valve clearances while you're in there.

Getting the HT leads and the hose to the rad neck back in, to allow the battery box to be put back in, after valve clearances can be difficult. A lot to be said for putting in flexible aftermarket leads, which necessitates new coils.

If the bike hasn't been apart before, brace yourself for some seized fasteners, by buying a large box of cobalt drill bits. Take as many bolts out as you can and copaslip them, for future ease.

I assume the fuel pump has already been junked? If not, now would be a good time to get rid of it.

Good luck.

Thanks for the replies; really helpful. Other than the lower fairing all the bolts have come out fine and this was no big deal as it still gave way pretty easy. I'll certainly do tappets, change plugs etc whilst I am in there. Coolant will get drained and flushed and most likely invest in Samco hoses.

I am toying with the idea of different wheels. It's just a question of cost against other priorities. I reckon at least 3k by the time i factor discs and tyres as well. I will be having a word with Jon at Racefit when I go to the bike show about exhausts though!

Do you have the Anchor wheels ??? Very Happy

Racefit do a legend system for a UJM for 1500 I think. I was going to have a look at the back of the system made but never got around to it.

I've had a set of samco hoses sitting on a shelf for about 3 years, not got around to fitting them yet. It's really an engine out job to fit them. Lots of other engine out jobs should be done at the same time... check clutch, rebuild slave cylinder, front sprocket etc

The bits under the headstock and the two hoses at the back of the head could be tricky with the engine in. BTW take pictures of the hose routing and on those back of head pipes the jubilee clips need to go a certain way or they'll foul the throttle linkage. It might be easier on the 6R with less headstock bracing.
