Vance and Hines Straight Shots.

[DaJa47]

:woohoo:Have gone and bought a set of Vance and Hines Straight shots for the C90. Can't wait to get them fitted. Pretty busy at the moment though so it may be a week or two before I get them on. Might be a bit loud but? Anyone else out there seen or heard them on a C90?

[johnnyflash]

cool, cant wait to hear em.. did u get em locally or import?...

[bmz2]

now your hp will go up, and we will here you coming:woohoo::eek:look out the c90 will be as load as the 9s, you will be able to chase some sportbikes:laugh:

[Angusdog]

I have the Cruzers for my M50 which are apparently quieter than the straightshots - and they are crazy loud. Have you given any thought to how you're going to plug the O2 sensor into them?

[bmz2]

I got straightshots on my VL800 and they are fucking loud. Good choice though!

Question : are straight shots legal ? I heard a rumour that they were failing them for a WOF cos they are too loud. Something to do with a change in legislation due to the 'boyracers' fitting loud pipes to their crapheaps .

Bought them from Sportzone Suzuki in ChCh. I have to say the guy down there was a great help in the accessories dept.. Very helpful. I have been in touch with a guy,Gary, in Ch.Ch.through the LC1500/C90 group, who has just fitted a set and he is happy. A bit loud but "Not overly Loud". I know I got the last set ($750.00 inclusive)I will catch up once fitted!!

The trouble is it's usually down to the tester. I got a prize twat at one joint but I simply went home, fitted the originals and got my wof, soon to reverse the muffler-swapping act. Six months later I got a wof no probs from a different tester with the loud mufflers.

Also, even if you have a wof and get plucked on the side of the road for whatever and the cop wants to be an arse'ole he can deem it too noisy all by himself and it's down to you to prove otherwise. This usually entails fitting quieter mufflers, getting a decibel meter test at an approved station and having your exhaust all written up etc. It's a mish. So, if you've got loud mufflers, don't give the rozzas any shit should you get stopped.

It's all so airy-fairy that most cops don't bother, especially if you're just cruising around but find yourself a friendly wof tester and stick to him.

[DaJa47]

.:no: Won't be able to make it. Got a builder here doing some work at home and I said I would give him a hand. I may also start fitting the pipes or may leave them and get them done at work next week. Have a big weekend planned. I sure want to get them on and I will be in touch.

[heyjoe]

Yep. What peasea said.

Enjoy your nice awesome sounding pipes and take it easy if stopped. Don't go out of your way to negatively attract attention to yourself. Do some quality networking at your local WOF testing station. This will give you hassle free riding if all goes well.

I took my bike down to the local testing station and had a civil chat to the boss tester regarding whether my pipes will pass. He listened to them and said he is ok with them but advises to take it easy. He said your behaviour can determine how cops or WOF inspectors behave. I have Cobra Speedster Slashdowns on my meanie and they are loud but awesome.

Most guys just cut the wire to the O2 sensor and bundler it up under the tank leaving it still conected without causing any problems with FI.

The guy I referred to earlier in Christchurch who has just fitted them, says he will not have problems getting a warrant. I spoke to him again today. The sound is good. I'll let you all know when I get em going. They do have removeable baffles!! Mine will be a stayin in.

Good advice. I couldn't agree with you more. If you go looking for trouble you will probably find it. Most of the cops are more interested in your bike anyway. You just got to be wary of the odd rsol and that's where your attitude can make the difference. Young guys 'Take Note' - Can save you heaps!

Iv got strait shots on my vtx1300 & it is louder than a mates 1800 with the same pipes & mine has baffles.:rofl:
Got a wof withe them on & its quit loud:mega:

Be interestiong to see just how you fit em to the vl1500 Daja47, you have had a peep at the plumbing on the C90 I assume, I suspect it aint just a matter of bolting em on ....

The collection box where the O2 sensor goes, comes out along with everything else from the heads back. You get supplied a new bracket where the top and bottom mufflers attach at the back.You take the studs out where the pipes bolt to the exhaust mainifold and replace with 30mm stainles M8 cap screws. The O2 sensor gets wound up and left under the seat or the tank and you cut or disconnect the brown and black wire going into the 23rd port in the ECU board. That apparently tricks the computer into thinking everything is still connected and it stops your FI warning light coming on. I have diagrams of this if anyone needs them. The weight of the original exhaust system is far heavier than the V&H and should give more ground clearance as well. Hope to get them done this week.

Ah, perfect info mate, brilliant description, Now I aint so worried about getting some sent in, Ill just wait till Ive heard your :laugh: I want mine a LITTLE louder but not TOO loud.. did you put a "Power Commander" on as well or stick with the Suzi original? I assume you will need to reset the ECU so it remeasure the new mixture etc ??

I've found that there's a similar "fix" for the M50 running V&H pipes (as mine is). As I understand it, you either leave the actual sensor attached (but reading fresh air, so not sure how that affects the running - it will be "expecting" to be reading exhaust), or snip the harness (on the M50 it's a different wire, but the same in principle). Again, not sure how this affects the running - does the ECU think it's reading 100% O2 in the exhaust, or 0% O2. And again, how does this affect the running? I think I'll try the former, so I don't have to cut the harness. Maybe it doesn't really matter as I can adjust it with the Cobra FI2000R unit I'm running.

I'm running with the O2 sensor disconnected and the FI light on the dash on for the last week, and it runs fine, although when you rev it at a standstill, it blows a little bit of black smoke - but the settings on the Cobra are as recommended for aftermarket pipes.

What intake are you running? The popular cheap mod on the M50 is to drill holes in or cut out the bottom of the air cleaner assembly on the RHS of the engine - once I have the pipes sorted, I think I'll try it. According to various specs, the standard M50 puts out 45bhp and the HD 1200 Nightster puts out 55BHP :)

Johhny Flash, the guy in ChCh took his bike into the Suzuki agent and they used a Teka SF1 re-mapping module. They plug it in, re-map, then remove it. He also put a KN filter on but that is not essential. He is quite confident he will get a warrant on the sound side. I should have mine on this week. When I fire it up at work in Albany, I hope you don't hear it from your place. Should be fine. I will let you know.

[Angusdog]

I had Wgtn M/Cs help me with my V&H Cruzers; they welded a pipe with one flute in it, so at high speed, it pushes the gases towards the absorption material in the baffle (in theory). It's taken the edge off, so the pipes are still quite loud but not generally offensive. Previously, when I opened it up, people 100m away would turn to see what was making all the noise. Although the guys at Wgtn M/Cs thought the pipes were okay to begin with, I'm really happy. I don't think I'll have any trouble getting WoFs or hassle from the man.

They did mention that it's a good ideal to keep the O2 sensor, so I'll weld a nut on behind the rear exhaust port and put the sensor there. I'm a bit sick of the FI light staying on.

[Angusdog]

Forgot to mention: The Cruzers have a much bigger diameter baffle. The cross sectional area of clear space inside is huge, effectively straight through. The Straightshots are much narrower so your options for quietening them down without losing performance are much less.

Hope to get them on tomorrow- all going well. I will post a message in case people don't hear them!! I'm not really thinking they will be too bad. Did you see the thread about cutting the brown and black wire into the ECU. It may not be the same on the C50.:(

[Angusdog]

Yup, saw that. It's not the same wire on the C50/M50 but the principle is the same. I'm going to try putting the sensor back on; All I have to lose is a mint set of Cruzers :)

I got the Vance and Hines Pipes on to day without any hassles. Everything lined up nicely and I am very pleased with the look. Having a stud removal socket made a big difference. Fired the beast up and she certainly puts out some noise but not too much. Sounds like a big Cruiser should in my opinion. When throttling down the exhaust "pops" alot but when she goes in for the 1000 k check next week, I'll get it re-mapped and I am sure that will sort it out as it will be running too lean at the moment. I left work in Albany and rode out through Riverhead and back out West to try it out. It may be the sound but it certainly appears much more responsive. Taking the old system off I found it weighed close to 28 -30 kilos. That would be more than twice the weight of the new pipes. The one thing I can't work out is that I disconnected the wiring from the O2 sensor and removed the sensor from the Pre-muffler. I removed the pre-muffler collection box with the rest of the original hardware. Wound the wiring up with the sensor in a couple of plastic bags and re-connected the plug in wiring. Tied it up and tucked it away under the seat. The advice I had was that at that point the FI light would come on when I fired it up, but it didn't. I was told that I would have to cut the brown and black wire going into the 23rd port(5th down on the right) on the ECU board to stop the the FI warning light coming on. When I turn the ignition on the light shows up with the others, but on starting, it goes. No doubt the service guys will sort it out but it all appears ok. I checked with the service dept and they said it wouldn't hurt to keep running it until the service. Hope to get that last 100 K up this weekend.:2thumbsup

Good on you Dajar... what do they sound like after nearly getting your head blown off by mine last week? :niceone:

Had a good ride back to Orewa from the shop - George got soaked with no wet weather gear, jeans and his wife's mirror visor. Had it open all the way home - water ran down his neck inside his jacket. I was snug 'n' warm all the way. :stupid:

Nice one DaJa47..Yep usually gain a few horses extra after changing pipes and also increasing the aspiration ( air filter change) according to a USA report I read the C90 was basically detuned to meet the local regulations & emmission control, the engine naturally has much more HP, with far better aspiration / exhaust pressures available without all the emmission control stuff.....Sounds like a remap of the ECU should sort the tuning ...

Young George was always going to get wet the other day with the gear he had on and that torrential rain.. When you fired that bike of yours up and it blasted me in the face, it was a preview of the Thunder and lightening to come.

Oh, yeah!!!!!!!!!!!!!!!!! They looks and sound loud. Be interesting to see what you think? It just takes a bit of getting used to after the original exhaust which is so quiet. Those cage drivers will have no excuse for not knowing I'm there, even if there eyes are shut!! At the end of the day, it's still look after number one and keep out of there way.:bash:

G'day DaJa47,
Your bike looks great with the new pipes on them and I know what you mean when u say "...sounds like a big cruiser should..." I thought the same thing when put Cobra pipes on my Meanie. I am not familiar with Suzuki bikes but I am assuming when you say 'pre-muffler collection box' you are talking about something like a chamber where the exhaust gases collect and do any final burn before exiting the back of exhaust? A Japanese emission control device. In the Mean Streaks we had something like that. This extra chamber (goatsbladder) also helped muffle the sound (popping) which is air/fuel causing small backfiring. Now with your new pipes you are minus this and can hear the popping louder. Another cause of the popping may be air getting in around the exhaust gaskets or them not sealing properly. It only takes a little leak to do it. Usually good advice to replace these gaskets on fitting of new pipes. Re-mapping may help with the popping and Vulcan owners do a thing called 'the marble trick' which prevents air getting into the pipes too.

Heyjoe. Tomorrows the big day. Pick it up following re-map and 1st service following 1000k run in. I don't think I had a problem with air round the exhaust gaskets as the bike had only done about 900k since new and all looked good. I will put something on KB to let you know. Even before the re-map it has more get up and go, especially mid range. Hope to go for a bit of a run with the North Shore Cruiser guys and put it to the test after picking it up! :2thumbsup

[heyjoe]

Good luck with that.

I noticed the throttle was a lot more sensitive/ touchy after I put the Cobra pipes on and it felt like I was getting a just a bit more torque but it was hard to tell for sure due to the beautiful sound I was now hearing and feeling. :woohoo:
I'm planning on getting a PCIII fitted when I have saved some more dollars to help smooth it out a bit and get it re-mapped/ dynatuned so everything is performing at its best.
