How far to go without re-chipping??

[Gromit]

If one is considering modifications, pipes/filter/induct etc etc how far would it be feasible to go before it'd be necessary to re-chip the Motronic?

Just bearing in mind that I've fitted a K&N, Motorworks do a Lennie's induct for the R (in much cheaper plastic -hurrah!) and I should be getting the Remus delivered by the end of the week. Clearly the motor will be shifting more air - but what latitude does the Motronic have? The R doesn't run a sniffer - only the German/US models do for the cat.

The same rules would obviously apply to the S.

I've been told by people that tune boxer engines that the engines run very lean in standard set up.
So by allowing the engine to breath and exhaust more easily you are compounding the situation.
I'd definately invest in a chip for peace of mind.
A good test would be to go out for a very spirited ride when you've got the K&N and pipe fitted.Then when you get back check the plugs....you will find the tips are whitish in colour.They should be fawn/tan brown.

I keep telling myself to invest in a chip but just can't bring myself to part with that much cash for something which does very little!

Cheers Bailey - pretty much along the lines I was thinking.

Saw you today - Stockley going towards M4 approx 1:15.

What's the latest thinking on fitting the fuel pressure regulator from the K1200RS ?

Used to be the preferred way of richening the mixture under all conditions. Relatively cheap and would take some pretty in-depth knowledge on the part of a loss adjuster to know anything had been changed!

Haven't seen this mod referenced for a while.

[Gromit]

MD - I'd like to know who's run this mod for large mileage (ie 30k+) I know Stempy runs one and rates its effect, but he's not a big mileage guy.

[bigblackfalco]

he is in the getting pollish from the local shops.......
if you know what I mean

ps.Maybe this would be a cheap alternative to a chip.I will talk to the oracle tomorrow(Darren at MW or Jim at Cray.)

I've had no ill effects so far, but as you say, being a summer time rider I still haven't reached 20k yet I think there are few on the Pelican side that have run the k12 reg and a couple of the Dutchys too. Not heard of anyone whos had any problems directly caused by using it. In fact one of the Pelican boys reported a better dyno graph with the reg than with the chip! Even with the tune up chip you could still run lean as they were designed to be used with the standard intake system, not with an induct, K&N etc.

The polish I use is specially imported

Yeah,come to think of it...think I saw you too.I was behaving badly though...went round that M4 roundabout at an astounding rate...
Yipppeeee

Richard, I've got 54k on mine with Laser, bb chip, k12 reg and lennies induct and I also completely removed the cat sniffer.

When I had just my old Remus system and bb chip I had it dynoed and it was very lean. I would agree with Stempy's comments about the K12 reg. Seat of the pants tells me mine is a little rich at lower revs, but higher up the range it feels spot on, as I spend a lot of time on the motorway this is more important to me.

Where do you fit the chip?
My bike has had all the usual mods u can think of, all done by the previous owner (£££Thanks!!! ) But i can't remember for the life of me if he said he'd chipped it. Where do i look to see?

[crucial]

The chip is in the motronic gubbins under the tank. Look here for a detailed explanation http://wijhenke.net/

How poor is the low down power with the K12 reg?Does it cough and splutter.What sort of revs does it clean up?
What sort fuel economy are you guys getting?
Bailey.

[stempy]

I get no coughing or spluttering, it pulls like a train from tick over to rev limiter, and is smooth as you like. Plugs have always come out a nice tan colour. Economy wise, the fuel light used to come on in the mid 140's and now it comes on mid 130's so I guess 10ish less miles per tankful.

[minivin]

130 mile and the light comes on? you running standard tank? my light always comes on at 120 ish

I know it pops and bangs a bit on the over-run but am I burning that much fuel

[stempy]

Standard tank, but I did drill a hole in the filler neck so I could over fill it.
