PostSubject: C800 Pipe Question   Mon Jul 25, 2011 8:30 am

Been speaking to Mike at Cusom Cruisers about getting Hard Krome 3" pipes. He says as long as lambda sensors are fitted (bosses come with the pipes for a bit extra cost) the pipes will run great without installing a fuel processor and he fits loads. I spoke to Thunder Road who say they have fitted Vance and Hines to the C800 without a fuel processor. I am not modifying the air intake. Anyone here think any different ? Thanks.

As you are aware there are more opinions on this than you can point a stick at from riders and shops alike, so good luck on deciding what to believe & go with.

Some say that the bikes own computer will work it out no matter what you do & some don't.
Some say that the bikes own pc can be updated to run it all fine no matter what cahnges are made and some don't & that includes riders and shops alike
Some say that if you only modify or change the air intake it will be ok and Some don't
Some say that if you only modify or change the exhuast it will be fine & some don't
Some say that you havte to fit a fuel injection module and some don't. i have just had a quick look at mine and it had made over 100 adjustments to air and fuel intake over the entire map

Part of the problem on the newer models is because it has fuel injection and we are all used to our cars taking whatever modification we throw at it and dealing with it but cars gave a lot of sensors. The bike is not a car and only has a small number of sensors to deal with fuel air intake & flow.
Part of the problem is that we all want to be right and the fact of the matter is that we can't be. The list of some says and my dealer said is never ending and most people
that have it one way or another will swear that the way they have done
it is the right way, so which one is right because they cant all be
right.

We need to remember that these bikes run lean straight out of the
factory so as long as we have faith that the bikes own pc can make the
necessary changes that all is good.
I would however add that there is a hell of a lot of people out there which is probably the biggest group of opinions, that the bike is fine if only the exhuast is changed and no change is made to the air intake.

Over to you blues, good luck in your decision, I am sure your way will be the right way

if you get a bit of pop and backfire then you could remove the pair valve or simply plug the vacume lead with a golf to and carru on. Happy days.

I would have to say from what I have read as well that you will be ok with pipes only, hell man you almost there with your gutted pipes already

Those pipes have got a bit of a bark to them under load but aint to bad when plodding

Same as mine & most after market pipes, generaly better flow means more noise.
Thats why all the kids piss about with their moped exhuasts because they think that it is as simple as more noise equates to more power. wouldn't that be great Laughing

If it was as simple as more noise meaning more power then my bloody mrs would look like Arnold Schwarzenneger

As far as the moped briggade goes yeah I noticed that.

I tried explaining to a hoodie once that more power is usually accompanied by more noise but that more noise is not nesaccerily acompanied by more power & he looked at me as if I had just tried to explain quantom physics and the theory of relativety in one sentance without the use of vowels

Yep I am ready for the noise! Phoned up to ask about gaskets today but closed on Mondays so will order tomorrow hopefully. Thought the same about the pair valve, saw the info on here. Will wait and see how it sounds. Had a bit of a rehearsal unbolting bits of pipe today. I think I'd better and might need a couple of new tools - ah the joys of doing it yourself! Pretty excited really - the near gutted pipes were noisy but a bit 'farty' - lots of nice sounding 800 pipes on You Tube and Mr. Intruder's maiden V&H ride in those stylish shorts of course! The last check I've got to do before ordering is that they don't have 'For Race Use Only' on them like my Harley pipes do, unfortunately. I should be ok with the Hard Krome's with the baffles in - I believe they wake the dead without affraid

Yeah I'm sure you are right in an ideal world but fact is 4 bikes in 12 months - so Mrs.B has now got the funds on drip feed - so I gotta be grateful for the pipes man!

Anytime a carbed bike is modified with either exhaust or k&n ideally you should rejet, it's not as hard as it sounds & will give your bike a new lease of life. However if it's only the exhaust then you will get away with it just!

Short fuse ..... my bike runs a carb and I've fitted Jardines with no rejet ... it takes a little longer to warm up but I get no other ill efects at all. Read in to that what you will but if it's running too lean, it's sure not showing up on the plugs. They were a lovely shade of beige when I changed them last !
