TPS types; protection needed

[dancata]

Hello all,

Can someone please enlighten me on the two types of TPS's that we have on our 11xx GS's? I am planning to built some aluminum protection for the TPS. These is what I have found so far from the TPS data sheet. So, which on eis for 1100 and which is for 1150?

Thanks a lot,
Dan.

Type B looks like the 1150 to me.

Based on reaoem.com, 1100, 1150GS & GSA have the same TPS, 13631461852 part # from BMW. Can anyone confirm that? So it's type B we all have?

 

[sockpuppet]

Well Type B is the one on my 1150

How are you planning on attaching the 'cover'?

if you use the normal fixing points for the TPS.. all you will succeed in doing is making the thing bigger and more prone to damage.

I do not agree to that!

If I am going to hit the potentiometer hard, maybe it's going to break, but if I hit the potentiometer not so hard, the worst thing that can happen is the cover to bend and the plastic to stay in place

If the guard is such a bad thing, how come TT sells it? Ever asked yourself that ?

"This guard for the throttle potentiometer has its origins in offroad biking.

Anodised in elegant black, of course, to match the bike. Its so easy to accidentally catch your boot on the
potentiometer without even noticing and thus change the settings. Our elegant and understated guard is
the perfect way to prevent this from happening."

"You know the problem, the throttle potentiometer connector, broken by your riding boot. With our attractive
rugged cover, this important electrical connector of your fuel injection system is protected.
Made of 3 mm anodized aluminium. The cover is fitted using two spacers and longer M4 x 40 head screws.

The right side potentiometer is very well protected thus only one cover (LEFT) is necessary."

Also, I am planning to do this: http://www.touratech.com/shops/008/...=4313&osCsid=15d194f021a37b5191581ae1800602b3

I am still in the design stage of the project. As my job is QA Engineer, I will test it in all ways possible

Any tips or pieces of advice are welcome!

Touratech sell lots of shit that isn't needed. They sell it because of the bling factor.

Given that a fecked TPS won't stop the bike from running and a 2nd hand TPS will cost you £20 its just cheaper to carry a spare as they are cheap and small.

But if you use the mounting bolts you may save the TPS but could destroy the throttle body as the metal guard won't give like the TPS would.

Now if you could do it but not mount if to throttle / air pipe then it may be worth it.

all the one's i've seen fit on the TPS mounts. they're bigger than the TPS unit so give more leverage on the small M5(?) fixing screws, and the TPS itself, in the unlikely event of it getting hit.

waste of time, don't protect anything and look stupid. maybe you can do better than TT? who knows?

good luck.

I was thinking of longer M5 screws for the TPS protection mounting, so that the screws would bend in case of damage. Maybe the aluminum plate will be 2mm thick to absorb the shock, along with the screws . 3mm is too thick.

So this is just an ideea. I am also going to make rear brake reservoir protections, etc. Like these:

Maybe a 11xx TPS protection is not needed because of the cheap TPS itself, but would you do the same for a 1200 GS/A ?

It's known that the potentiometer is very sensible; I don't know about you, but my left knee can rest on the TPS while waiting at the traffic light for example.

And just because TT sells them for big bucks, I don't think you would refuse one for let's say... half price?

Yes. Because it would still be £15. For £20 you can have a second hand unit which also works should the TPS break though non impact related issue.

Even if the TPS dies the engine will run just use shit loads of fuel.

Make them. Someone will buy them.

i suspect that if the screws bend, the plastic mounting flanges on the TPS will break.

Well... that is true... but I was thinking that there is no way of such a force to action on the TPS so that it will break... How many TPS failure cases have you heard of because of mechanical damage?

Anyway, tomorrow I hope I can make the first one, then powder coat it then install. Will add pics as the process goes on

Thanks for all opinions; I really like to hear your opinion on this.

Dan.

you could attach a big ali lever to it. that might work

none. so why do we need the guard?


i do see lots of these guards, and the equally pointless brake reservoir guards, on peoples bikes though, so there is definitely a market there. guess they just like giving their bike little "treats"

just my opinion.

fit engine bars.get piece of scrap ms,drill tap 2 mins with poxy arc/w,job done,confused? PS the TT part mounts in the same place as the part making it more likely for you to F&*ck it,just more bling

 

[dancata]

But I do have bars, SW Motec I am still going on the variant that the protection will do it's job for small kicks. For bigger damage... I will have to think about the mounting screws...

Anyway, after all will be done, I will test it rigorously.

The vulnerable point on 1150/1100s is the fuel pipe just before the injectors so if a guard is needed anywhere it's there and that's a problem to design and mount.
In some countries strangers climb all over your bike and breaking that pipe is a real and likely show stopper!

I'm, er so it seems here, guilty of having a TPS guard (bling) on my bike and the reasons for not having one should have come to light with the way I use my bikes....but it hasn't

So I'd say it's ok to fit a tps guard but it really is bling, better spend some time designing fuel pipe/injector guards (like the 1200 ones)

That sounds interesting... Do you have a pic of that so that I can design it after?
