Hi can anyone enlighten me or have any ideas ?
I have just purchased some stainless downpipes for My R1200Gs TC from Keihan

However the diameter of this pipe is much smaller due to having no cat.
On the standard system there is a central bracket that goes around the cat and attaches to the bike with a rubber mount.
Motorworks said that since the new down pipes are much lighter you don't need it ?
Seems a shame not to utilise it so has anyone made some mods that enable it to fit ?
Regards all
 
Oh and I am pretty sure it's an option from keihan but seriously you don't need it.

Yep Keihan will give you one if you ask, I never used mine because there really is no need for it at all.
 
Same, I got one with the headers and never used it....no problems. You are gonna love the increased performance and noise.
 
And again. I had one supplied with my headers but it was awkward to fit so I didn't bother and the system feels very secure without it. Big difference in preformance, and a bit more noise. Are you going for a re-map or Power Commander? the bike runs quite lean as standard and even more so with these headers.
 
Yes planning a trip to hilltop especially if I can get a group and a discount

You won't regret it. I had my TC Hilltopped last year and it made a big difference, smoother, faster, more responsive. I'm still on the standard end can and air filter as forum wisdom is that these are perfectly OK.
 
My Akraprovic titanium system has a middle bracket but it is built to take the demands of desert racing. Many bikes have only the front end and back end mounts so the middle one is belt and braces.

I have a Power Commander V on mine that had been set up for another bike with similar specs to mine. Anyhow its always run a bit rich but way better than the OEM fuelling. The other day I took out one of my baffles (shotgun system). Its made a huge difference to the bike. It was great before but now it's really great.

The remap is the better option because it allows the ECU to adapt to exhaust system changes. The PC wont do that without some retuning.

MikeyBoy has two K&N filters for sale. Fit one when you have it Hilltopped but not before. They do clean the air properly but only a dyno run will show if its really adding any performance value
 
Thanks everyone for the help and pointers
I'll see what the exhaust is like when I fit it but knowing how finicky I can be will probably want to use the central mount anyway!
Defiantly going to hilltop as I am never selling the bike.
Not a fan of K&N as people can put too much oil on the filter and clog it up when I was into rally cars pipercross always came out better with the foam filters.
However always willing to be corrected by an expert
I'll ask Keihin about the bracket
Thanks again
 
Vizard was saying the K&N fine fibres with the sticky oil are what catch the fine dirt. So too much oil isn't good. The OEM filter does a good job. Restrictions in the airbox and intake tube are a bigger factor than the filter.
 
My bike was the protype for teh Keihan pipes and I've had mine on for 100,000 miles with no support bracket with no problems. It's not an "A" road queen either and it's been off road and the Dalton 5 times.

I sold a few sets on here when they were first out and people wanted a support bracket. Keihan made one to suit although in my opinion it's not necessary.

Give them a call directly if you want one and they will supply you no problem.

Don't bother with teh K&N as they are an expensive trinket which does no good on the GS. The standard filters are excellent and offer much better filtering than the K&N.
 
I can't agree that standard filters are better air cleaners than K&N but on the GS, any air flow benefit of K&N is not worth the expense. The used K&N from MikeyBoy are priced to compete on cost so you have in effect a permanent filter just clean, oil and refit.

I used a K&N in a diesel Montego (anything to help reduce the smoke). It did 140K before the bodywork fell apart but the engine was still going strong.
 
Showing your age bendy toy !Montego indeed!

Bought in 1989 and sold/scrapped in 1996 (or was it 97).

Dynamically it was quite good and stupidly cheap to run. As ever with Longbridge cars, the paint was probably wafted over bare metal.

Over it's 8 years with me, it had one clutch, a new generator, one new battery, front wheel bearings every year and other wear and tear parts at normal rates.

That was it
