Performance Gains

Who would be recomended to dyno test and set up a full Remus system on a GS1200 in the North East or North Yorkshire

Shep,

Another observation is significantly less torque reaction with the new bike. I think this all adds up to the feeling that there is less 'pick-up' but I suspect this is not actually the case.

Er, didn't anyone notice the blurb about the 1200 being the first boxer design with a balancer shaft ???
 
Remus Genesis on 1200GS at 5,800ft (1,800m) above sea level

I've just had a full Remus system installed on my 2006 1200GS (headers/'Y' piece and Genesis end-can). The bike has only covered 1,000km, and I've only done a few mikes (km) on the bike since fitting the system (fitted by the dealer immediately after the 1st (1,000km) service).

Johannesburg is about 5,800ft (1,800m) above sea level, so all vehicles have a reduced power output here (though turbo vehicles seem to fair better) and the summer temperature is 30degC'ish.

The Remus web-site recommended the Revolution can, but the BMW dealer here recommended the Genesis can.

Sound is certainly improved, but it is too early to say what the effect on performance is. Hext is a K&N filter to help 'breathing' at this altitude.

The 'popping' on a trailing throttle is much more noticable (as discussed in another thread).

Does anyone else have this setup? and, if so, what are the impressions?

David.
 
Ja Boet -
got identical setup on my 1200 ADV (6000km) and can say it makes a big difference (certainly the Genesis is louder than the Revolution and while not a major problem in RSA it would be in Europe where it is considered a 'race can' and not for road use). I have complimented it with a K&N and slightly modified intake snorkel (more air in more out). I also picked up a Wunderlich Power Controller than refines it even more...the bike now really hops. Also visit the USA Advrider (GSpot) website for further info on exhausts and all GS etc :thumb
 
Remus Headers and Genesis Can on GS 1200 Melting Numberplate

Just an update - the Remus headers and Genesis can sound nice and do improve the performance - 'breathing' is important at this altitude (approx 1,800m here in Jo'burg).

The pipe doesn't seem that noisy compared to my previous bikes (GSXR's, etc) with standard systems - much loader than the standard GS 'sewing machine' system though!

the BMW dealer that installed the system said it 'might' burn the numberplate/backing - that was an understatement! After 1-200 km, the backing is melted and the numberplate is toast!

Has anyone designed an elegant heatsheild?

I stuck an ally. plate onto the back of my number plate, it just spread the heat and melted more of the number plate :D

I now run a 1" smaller number plate - sorted :thumb

yep the smaller number plate seems to be the best solution
 
I would but I can't - smaller numberplates don't seem to be available here in South africa (some people just take them off!).
I was thinking of scanning it, reducing it, and then laminating it/putting it behind a piece of perspex - it would be more camara unfriendly too! :thumb
 
Erm
Am I alone in thinking that bolting on all this overpriced performance enhancing junk onto a bike like a GS is a total waste of time and money??
Loud pipes just get you unwelcolme attention by the police and make the chances of getting off with a speeding ticket zero as well as upsetting the neighbours, residents of small villages on our favourite twisty roads and other road users??
And as for boosting the performance of a touring bike - get outta here! Ive ridden mine two up with luggage and still been held up by a bunch of sports bikes on a good twisty road. It will also cruise effortlessly on the mway at any speed thats vaguely acceptable. As for not having enough topend? buy a sports bike guys. If you want to go faster on a GS then corner harder

I agree with most of the sentiments.

Here at 1,800m above sea level, vehicles loose performance (they say 20%, but I've no way of prooving it) - having never ridden a GS before I came here, I can't assess the difference.

I guess the performance mods may add 10% so, if the GS was 100 bhp at sea level, and you loose 20% here, then you get 10% back, that would put mine at somewhere around (or just below) 90 bhp.

same cost as the servo/ abs option - decided i would rather to spend the money on this !

seriously though the bike runs really well and feels stronger/ smoother than stock - subjective but i think the standard bike lacks a bit of top end power (especially compared to the KTM 990 i tried recently).

Interesting economics going on here. A bike with OEM ABS will sell for more than one without (all else being equal), due to the intrinsic residual value of ABS. Whereas a bike with a chip will sell for the same (or less) than a bike without the chip.

Which makes the chip considerably more expensive than ABS...

Why is is that people make decisions on the absolute cost of items instead of the total cost of ownership??
 
If you bought a bike purely on the economics then in all probability you wouldn't :confused:

Or "performance" chip gives positives extra accelleration, mpg etc, ABS is negative, I don't want to slow down :P

BTW I've got both on my bike (an 1150 GSA :o ) 'cause if the chip does let me accellerate quicker, I might just need the brakes that bit more :o
 
Not suggesting that you buy a bike on economics at all. Just questioning the logic used when ordering optional extras when using price as a measure. Of course, there are other measures (grin factor).

Some extras make better economic sense than others. For example, you get back a significant chunk of what you spent on ABS & heated grips. Other extras have negligable resale value and I'd contend the chip falls into that category. With a car, its always worth forking out for metallic paint over a boring flat colour (eg white) - just look at most police cars these days...

Of course, you are right (to a point) but I don't think many peeps here are replacing the exhaust in order to achieve ultimate top end power :confused:

Have you ridden a GS with a full after market system?

I have found that my Bos system has made a real positive difference to the way my engine responds. It is more tractable lower down in the rev range, the midrange power is notably 'fatter' and the flat spot just below 5000 rpm has all but gone now. All characteristics that make for a better, more enjoyable ride. There is slightly more power at the top end but, TBH, I hardly if ever use it.

And, whilst it has a nicer 'tone' I'd hardly describe it as loud (it's fully road legal).

Oh, and it weighs significantly less and looks a lot better than stock IMHO :thumb

I fitted a set of Remus headers the day I bought the bike as I wanted to be free of the cat and since then have tried various end cans including the stock one before settling on the BMW Akra can which I currently use.

Personally it's not just a case of top end increases, I've enough points on my license as it is, but I like the sound and feel of the bike with the aftermarket products and even more so since fitting the Wunderlich Power Commander a few weeks back.

The bike runs smoother than before, has an increase in power and torque not just at the top end and for some reason I cannot understand the fuel economy is better which is an unexpected bonus.

I do not intend to have the bike on a dyno, personally I don't fancy running an air cooled bike on one no matter how big a fan they use but I've looked at enough charts recently to confirm what my backside is telling me, at the same time it's simple to take the Wunderlich out of the equation and try the same route back to back, and in addition I can alter the fueling to allow for the can with or without the baffle without needing to hook it up to a lap top.

I'm not saying it's an essential modification but it is one that I'm very happy with.

This is a dyno run of the PC with a stock system.

and this with a full Remus system and after market air filter.
