I've been given an Art Pro Series II can for my TT600, which I have fitted and it sounds fab! (I had to put the baffle back in as it was giving me a headache)  It seems to be running fine to me and doesn't seem to be any different to me apart from the loudness and "gurgling" noise, with my limited experience, so do I need to get it re-mapped or is it ok as it is?  I don't want to damage the engine or anything.   Also do I need to tell my insurers?  Art don't make cans any more so I can't contact them to find if it's road legal.   Thanks Lisa                                                                                                                                                                             

I have an old Art brochure somewhere, I'll dig it out and see what it says but I suspect that you will require re-jetting and possibly re-mapping too ? I'll get back to you asap Meanwhile, just to be on the safe side, either be gentle with it (no BIG fistfulls) or swap it back till you know for sure Sorry I can't be more positive But better safe than sorry, you dont want to hole a piston with a weak mixture, no matter how gorgeous it sounds Em                                                                                                                                                                              

Sorry Hello There the brochure only lists Pro Race cans of various shapes & colours You might try looking for a local supplier of a SIMILAR can (which I think is a "slip-on" but will stand correction )  and asking if they recommend any mods to jetting & mapping ? Shame I couldn't be of more use to you I do you you get the issue settled, for your own peace of mind You might have openened up a "can o worms" (sic) ... but It may turn out to be a wonderful gift      Best of luck Em   PS if its any consolation  these were listed in 2000, at anything from £90 odd for "universal" slip ons to £460+ for a Blackbird,Ducati or early Triumph I assume thats for a pair                                                                                                                                                                               

I  thought all Art Pro cans  were track use only 

                                                                                                                                                                             

Well thats what I thought Gloom but couldn't say for sure                                                                                                                                                                              

Does it say not for road use?
If not it's ok !!
most cans won't make much differance without re mapping.

                                                                                                                                                                             

I've got an Art Pro Series 2 on mine, on the stainless band at the end of the can it said "Not for road use" on, but when I polished it this amazingly dissapeared   I had a K & N air filter fitted and a stage 2 Dynojet kit fitted, it sounds really nice, if a little loud, but it always goes throught the MOT and I've never been 'spoken to' about it, even when I've ridden out with Police officers.   And yes, you should really notify your insurance, then if anything happens they will cover the cost of replacement                                                                                                                                                                             

lol tell the insurance nothing!!   changing the can on my previous bike and needed a stage 1 dynojet kit .....£105   it was only required because it bogged at 4k revs   ive had other bikes that didnt need touched....so if it runs ok i wouldnt worry   agree with Ian....if it says not for road use it will polish out  get out the autosol. lol                                                                                                                                                                             

There speaks the voice of experience X 2   I said I'd stand being corrected and I do   Best of luck with your "gift"     Em                                                                                                                                                                              

Thanks for all your replies and taking the time to check things for me. I've been told by an ex Triumph technician if it has a baffle it it doesn't need re-mapping or anything, also I checked it was still doing the same miles to the tank full and it is, so that's good.  I can't see a "not for road use" stamp on it, but I didn't look very hard! lol! If there is one it's on the underside so the police wouldn't know without taking it off anyway.

I have Art titanium cans on my Raptor. They did say "not for road use" on the rear end strap,  It cost me £6 for 2 new straps (complete with BS numbers on them) and a little time to rivet them on, and all of a sudden they were road legal! I got it on a dyno and was told she was running FAR too lean to be safe, so a K+N and Power Commander followed very soon after.                                                                                                                                                                             

you should always notify your insurance or you could find if you make a claim they may refuse it, most ask if the bikes been changed, i,v changed lots on mine always told the insurance and not been charged any extra                                                                                                                                                                               

I've got a full race system on one of my bikes.
It has no stamps on it so I asked the MOT man his opinion. He said if it doesnt have 'not for road use' or 'race use only' then its OK, I asked about riviting on a BS stamp and he advised against it as its fraud if caught, so he now MOT's it every year no problem
