Snorkel, filter and more fuel

[Deleted account 211025001]

My bike's now out of warranty and done 24000 miles so is up for a service that includes the air filter being changed.

Seemed like a good time to fit a K&N but I was a wee bit worried as having already fitted a full BOS system the bike may run a bit weak

To the rescue comes a Techlusion unit (2nd hand from Wraithrider ).

So, I wonders to myself, now that I have everything I need to do the job properly why not cut down the intake snorkel as reccomended by Plasmatron - so I did

I now have a bike that will not, no matter how I try, pop on the over run/trailing throttle BUT............ she now pulls sooooooo cleanly from virtually no revs. The slight dip/hesitation that was left around 5000 revs (even after the BOS system was fitted) has now completely gone and when the throttle is wacked open it reminds me of the pumper carbs on my old Lemon; no hesitation, the bike just surges forward

The best bit though is at 6000 revs with the throttle on the stop. Where as before the power would start dropping off and it would all start to go a bit flat the bike now feels as if 'coming on cam' and accelerates hard all the way to the rev limiter - it feels like a totally different engine at this point. Very, very addictive

Not sure if it will pass Euro III now though...............

Fitting was fairly straight forward, I've just ended up with even more wires and plugs

Here's some piccies:

Ready to go - look at all those wires

Standard intake snorkel ready to come off

Dirty, dirty filter

One long intake snorkel

And one not quite so long

Air, give me air......

All those wires

Andres,

I have on of these (Wunderlich Power Controller?), but have not fitted it yet.

Did you have to change any of the factory pre-sets?

Cheers,

Dave.

I used the set up reccomended in the instructions for "blue filter,and Remus" - on the back page IIRC.

I had a conversation with somebody on here (can't remember who ) who took their bike to a dyno and tried to improve on these settings but couldn't, hence I've decided to leave as is.

Hurry up and get it fitted, you won't be disapointed

Very similar setup, only difference is I have full Remus Genesis and concur with all you say (except still have some popping but maybe need to reseal the zorst). These mods transform the rideability very noticebly. Only other comment is I wish Techlusion would sort out as decent grommet connection to close those wires at the plugs (as with OEM) ... rather tacky IMHO.

 

[dlevett]

Mine's got Remus headers and a Remus Genesis Can (no issues with noise regulations here) and will, when I fit the Power Commander) have a K&N filter.

The only difference here is that we are 1,800m above sea level, and it is usually quite hot and with low reletive humidity (can briefly get down to freezing on a winter morning, but soon warms up to around 15degC).

It's going in for an oil change on Saturday (3,500 km - last at 1,000 km - I believe in regular oil changes), so I''ll probably fit the K&N and Power Commander then.

Well you certainly have the full monty now!
Do you plan to do a Dynorun with this setup???

Also: If you can please try out the difference with and without the air intake mod. Just borrow an original pipe somewere.
Looking forward to your report@
Thanx

That's twice you've used the term Power Commander. Do you know something that I don't, ie have Dynojet finally released a Power Commander for the 1200s....?

Have a full bos system on my 1200,do you have the baffle still in.
My god the sound without is just great cant help giving it big handfulls of gas.
Does the techflusion box have settings for all types of set ups listed or is it going to be a dyno job.
Thanks Craig

Schtum,

Sorry, I should refer to it at the Wunderlich Power CONTROLLER not commander.

I got it from Nippy, but the information is here: http://www.bmwbikebits.co.uk/shop/item.asp?itemid=3283&catid=

Cheers,

Not all of us are at 1 800m! Some would consider it a bit early in the bikes life to go full monty mods ... run it in properly first IMHO. Hey - and do the oil changes yourself ... and not full synth just yet.

I don't really consider any of the mods as 'Full Monty Mods', the headers and exhaust were fitted by the dealer at 1,000km or there abouts (questioned whether it had any effect on Warranty and they said no).

The air filter is a simple replacement and, in Johannesburg, may compensate for the alitiude and reduced air pressure.

The Power Controller appears to be a 'plug and play' unit which (simply?) corrects the mixture to compensate for the free-flow exhaust and air filter (I may have to change some of the settings to allow for the altitude (cars and bikes have reduced performance at this altitude, which is why most launches and tests are performed around the Cape, closer to sea level).

The only mod which is a bit radical is the snorkel mod and, to be honest, I'm not sure I'm going to do that one - I like to keep the mods completely reversable.

On the oil front, I will be sticking with mineral oil for at least 20k (which, of all the advice, seems to be the consensus) - I was recommended, by the dealer, Castrol GTX High-Mileage. While under warranty, I prefer to get the dealer to do oil changes - costs more obviously, but can't be any comeback.

Hey boet just my 2 cents worth from one who has done the same mods. Seems BMW Mororrad SA likes to recommend the Castrol Actevo (part synth) ... they changed out my oil at 1 000km to Actevo and I squeeled that I felt it should stay dyno for 20 000km for rings to seat etc... Gunther Mayer (Head of Technical Services) assured me Actevo was recommended and was OK, but they would change it if I really wanted to GTX or similar. In the end I kept it in and bike hardly uses a drop of oil now at over 10 000km (ran it in fairly 'briskly' I think it is the full synth one must be careful of during break-in ... basically works too well.

 

[dlevett]

Thanks for the reply - I'll check with them on Sat that they are using good 'ole dyno oil (hopefully since that's what they recommended for top-up!).

Mine seems to be on the 'good'ish' side for a bike which is just loosening up - I've just had to add a splash of oil at 2,500km from the first change (which was at 1,000km), this, from the various posts, seems to be good for the boxer (though my car has used zero oil in 15,000km!).

It would be good to Dyno mine against a standard bike with a similar mileage at this altitude - I suspect that all the mods will only have brought it back to the performance of a standard bike at sea-level. The major plus point should be the elimination of the 'dip' around 5,000 rpm.

Cheers,

Dave.

Yes, the baffle is still in and the instructions do give base settings as well as 'full monty' settings. IIRC you can download them from the Wunderlich site.

As somebody here said they had done a dyno run and couldn't improve on the reccomended settings I probably won't bother. IIRC they measured 100bhp at the wheel on their run and my 'seat of the pants' would agree with that

I suspect that the snorkel mod only comes into play at speed/high revs but, if I get the chance to swop back I'll certainly reprt my findings

Yeah, I would tend to agree but the thing that swayed me in the end was that a new snorkel is very cheap to buy. TBH though I'm not sure how much of a difference the snorkel mod makes

The Wunderlich Part Number is WC8530120, and the instructions are here:

Glad to hear that the techlusion is giving you as much addictive fun as it gave me.

These things work and opening up the engine breathing while retaining the original mix will make the bike pop and fart and, more importantly, run so lean that you risk long term overheating damage.

Also interesting to notice that the 'Nerdy Member' that I changed is back. Some sad f*ckwits about

The 6 P's

 

[dlevett]

I'll enquire how much the snorkel is at the dealers here in South Africa - if it's fairly cheap. I'll do the mod (after the others) and report the difference.

 

[ECM]

This snorkel is about €80,- (53 pounds?) So it doesn't come cheap!
