I just started fitting a set of CRM pipes to speedy, only to realise the o2 sensor on my bike has a different thread (smaller) than the socket on the midpipe.

has anyone else had this problem, what was your solution?

I'm sure Bob will see me right with this, I was so looking forward to taking the bike for a spin this w/end with the new pipes, but I guess it'll have to wait :'(

Are you in Australia? ( I assume from your flag avatar ) and it's an '07?

I expect that it does in fact have a different o2 sensor than other bikes. Nobody I've heard of has had this problem, but then again I don't think Bob has sent out any pipes for 07's yet. The 07's here are different, and require a special half system. I don't know about Australia. This could be the difference.

Does everything else bolt up correctly?

Yep, I'm in Australia, and it is an '07, but it's one of the earlier '07 models, with what appeared to be an '06 exhaust (o2 sensor is in the midpipe, not the header like the '07 pipes)

everything else looks like it will bolt together as expected.

What I'm thinking is the sensor is just different. Your best option may be to get a sensor off an 05 and see if it's the same. (take it in to the dealership and compare) or possibly having a machine shop turn you an adaptor. You may be able to buy an adaptor if it's a standard pipe thread (I don't remember).

You could also send a PM to 1050pome. He has the ChainReactions installed, and as I recall he lives in Victoria or some such place. Perhaps he could help you.

Good luck! Let us know what you figure out. I'm sure Bob will be really helpful too, but that's a lot of shipping and time!

yep, thanks crash, some good suggestions there.

other than thread size could there be any other differences with how the '05/'06 vs '07 sensors read and provide data to the ECU?

Ok, I've pulled the o2 sensor from my bike. I'm hoping I can just get a different sensor that fits the bung on the midpipe.

I was hoping someone (preferably someone with CRM pipes) could remove their o2 sensor and let me know a part number, so that I can be sure to get the right part.

Mine is an NTK AZ00101-VB002, so i guess i'm looking for something differentto that.

Is there any conceivable reason why the Aussie release bikes might have a different sensor? does it the o2 sensor differ from SAI and non-SAI bikes?

Thanks,
Jonty

Most O2 sensor threadss are M18 x 1.5. I don't know what other sizes are common. You could get a stainless steel M18 x 1.5 bolt and drill & tap it for your sensor. I think most exhaust shops have plugs that will fit the sensor thread and could be drilled & tapped.

Hey, Jonty.

Is it the thread or the thread and width that is different?

I can check for a part no. off my 05/06 tomorrow if you want.

it's a completely different size thread - M12 I'm thinking, as apposed to the standard M18 X 1.5 Boss that has been fitted to the midpipe.

My first course of action will be to contact the local performance exhaust specialist to see if he can fit a suitable boss to my midpipe, so that I can use my oem sensor. otherwise I'll look at fitting a plug that I can drill and tap to take my oem sensor.

Hey Jonty.

My 05/06 is the M18 1.5.

The only numbers I could see on it are 5E10.

Thanks for the responses guys. Had a fabricator cut off the original boss and weld on a new boss with a M12 thread.

The pipes sound great!!

Now the damn bike won't start, after I attempted to load a new tune for the pipes, but I have another thread on that front...
