Hi guys/gals my bike has a full akrapovic system on it but has not been jetted to suit so runs a little rough low down i have been online looking at various dynojet kits and was just wondering which one i need? Do i just buy a stage 1 dynojet kit and take it to a shop with a rolling road and get them to set it up or what? Cheers, Mark

I had dyno jet needles which are very soft aluminium so they wore out very quickly, I went down the Factory Pro titanium needle route with nickel emulsion tubes, I did however get it set up on a local dyno as I got fed up messing about with the carb settings

Sorry mate - don't mean to p155 on your bonfire or owt (honest!) is this the same bike advertised on the 'Bay' recently? Don't know what the seller told you but the exhaust isn't a full Akrapovic system, they're just stickers on some oval carbon cans which deffo aren't Akra & what look like standard headers.

Just pointing it out in case you'd been mis-lead?

AS for jets.. If you do indeed need a rejet, most any bike shop can sell you any brand, as can the tune-house. Factory pro, DynoJet, etc.. Find one which suits your budget and is a name brand. They must all be the correct size, so they basically do the same job as long as they are installed and tuned correctly.

PS: KEEP YOUR SPARES !! always useful.

what a b****** you know when i was washing the bike i thought the stickers looked a little budget for an apparently high end exhaust, at the end of the can its says ''typhoon'' dunno if that rings any bells...So how do you know about the exhausts? Anything else you know about my bike that i don't haha

it doesn't say Typhoon actually it says Harpoon, which i looked up and it would seem Harpoon is a totally different can manufacturer-what a bummer!

lodge a complaint with paypal and get a refund if thats the case. Take pics of the writing / pictures, also find what a genuine exhaust for that model would look like, and unless the listing says its a copy, you should be golden. Will take up to 3 months, but seriously, keep at it and get a refund. If you are lucky, you will even keep the exhaust. Paypal covers the gap (may as well use the insurance they have).

its actually my own fault, the bike never had much info listed with the sale and the guy i purchased it off played dumb to my questions as he had not owned the bike for long, it was a bargain anyway so im not to bothered-as you will know sounds the bees-knees too
