stage 1-the harley tax!

I'm picking up my new Sporty 1200R on saturday morning, when I orderd it the salesman asked if I wanted the stage 1 kit putting on. I thought I would leave it until the 1,000 mile service. My 'problem' as such is what to do regarding the exhaust pipes. I believe Screamin' eagle are no longer available, and to be honest the ones I had on my FXDX were a bit too loud, I was pulled by the cops a couple of times but thankfully never done, just a friendly warning. When I took the FXDX for it's MOT's I had to put the standard pipes back on.
Is there a set up that is a halfway house, ie; a bit louder than standard to allow that lovely potato potato sound out, but quiet enough to keep the law at bay. I realise that the traffic cops are more interested usually in the sports bike riders with their race cans, but I just don't want any hassle, I've already been done for speeding twice in the last 12 months. I saw an FXDX with a Vance and Hines short shots system, it looked good,but I never heard it run. I 've been told that the V+H pipes are not stamped with 'Not for Road Use' as the Screamin' Eagles were, but that still doesn't make them road legal. Can anyone advise??

Re: stage 1-the harley tax!

Can you put pipes on without changing the jetting the way you can just put a slip on can on a Kawasaki zx6R?

Re: stage 1-the harley tax!

You can't change any exhaust on any bike with out changing the jetting. The input to the engine ( carb setup ) and the output ( exhaust system) are tuned to each other. What goes in must come out. Put more in faster more has to be let out faster. Let it out faster and you have to put it in faster. Like a set of scales.

Re: stage 1-the harley tax!

in my experience, you can normally put a can on a jap bike and it will run ok, as they are set slightly rich. the probs come when you put a full system on. i had a zxr750 and a sv650 before the harleys, both had change of end can, and both ran perfectly well. the zxr needed a rejet when i put a full system on and filter, but the sv ran fine even when i put a filter on. no need for a remap on the ecu, and i checked it on a dyno and the guy said it had near as damn it perfect fuelling for those mods.
dunno about harleys as they run a little lean i think, but you may be ok with just some mild mufflers. im sure someone on hear will tell you more than me.

Re: stage 1-the harley tax!

I have a 2005 883 Low and have recently had the exhausts changed to the Vance and Hines slip ons. I didn't need to change the jetting or the air filter. They cost me £305 - including fitting (from the local Stealership). They sound really nice with a low rumble at tickover and throaty roar on acceleration....they also seem to have improved the bikes performance - unless it's just that the bike has done 1500 miles now and is run in.
Either way, I would recommend the slip-ons.

That makes sense. My Ducati had Termi's on it and ran ok without the performance chip but I was advised to get it chipped (basically an electronic rejetting I think) and it did run better.

Bexx, did the stealer say it would be ok for the slip ons? I am not too fussed about performance but the noise the stock bikes make is pretty pathetic!

Re: stage 1-the harley tax!

From what I know of later Hinkley Triumph fuel mapping (and I think I am right in saying, that most modern F.I. bikes are the same), to a certain extent you can change the pipes without uploading a new fuel map as the CO sensors will automatically "remap" the fuelling to suit the changed characteristics of the new exhaust.- but this is at best a compromise, and a dedicated map will suit much better.

Re: stage 1-the harley tax!

I've just found some 'Kestec' supertrapp legal loud mufflers. They are TUV approved, and according to the info they are loud at standstill,100dba, and when being ridden about 80dba. they were in the 2005 edition of the W+W catalog, sez they will fit sporty's up to 2001. I'll make some enquiries to see if they will do the later sporty. hope so, they look ok.
Bexx, are your V+H slip on stamped in any way other than the manufacture's name?

Re: stage 1-the harley tax!

I've just put a BSL 2 into 1 stainless exhaust on my 1200R,it comes with a "race" baffle and a VERY restrictive one.the choice is yours.it is tuv approved and has not got any "not for road use" markings on it.You can get all sorts of alloy end caps for them as well. A quality item made in Austria.Bloody expensive tho. Got mine off ebay for £350.Brand new it is nearly a grand!!!!!!!!!!!
Run mine with race baffell(how do you bloody spell baffle?). Lost the potato potato to a degree,not so offensive on start up.sounds nice when you wind it on a bit.
BUT,and this was the embarrasing bit,I found that i could'nt re fit my mid controls and I had to splash out on forwards,DOH!!!!!(I have an understanding wife)
Mind you,I did'nt realise forwards were so comfortable, so they're staying.
I reckon if you went to a good indy you would be pointed in the right direction.All American at Hartlebury very good & we get a discount of 10 or 15 % i think.

Re: stage 1-the harley tax!

V and H slip ons are not stamped other than with the makers logo. There are also additional baffles that you can have fitted which reduces the noise output by about 4db ( I think) The stealership told me that they are road legal and should not cause any problems for MOT purposes etc.
I leave for work at about 7.30 ish - I live in a built up are and have no complaints re: noise (so far)....and I have to agree - the stock pipes are rathy weedy when it comes to the Harley sound.
