If you like other mufflers just contact the seller on ebay and ask him the ID of the muffler's inlet and the length!
Inlet has to be the same size as your stock exhaust or matching the OD of the outlet of the KEDO downpipes! As for length, a longer muffler will be better for high speed..MIDDLE TO TOP RPM! A shorter muffler will be for ''power'' { LOW to MIDDLE RPM!} Vando :cool4: |
I did not notice any improvement to the performance of the bike with the headers, piperx and silencer until I took the snorkel out, then I definitely noticed the bike had more pull.
But the Dyno showed the BHP pretty much the same (33) although torque was better/higher. The guy said he had another XT600 in last week, not sure what silencer he had but he used a dynojet kit Motorcycle Exhausts from BR Special Tuning and got 37 BHP and got a second curve around 5500 revs when the secondary carb cut in. My graph was smoothe until about 5500rpm when the line jumped about a bit, he said it is running weak from 5500rpm and could do with the dynojet kit which is a stage 2 kit. So I am not sure if I should get another silencer, probably no point getting another road legal one, if I get one it will need to be a race can but I don't want be getting pulled by the police or annoying my neighbours with the extra noise. I could also get the dyno kit fitted, cost of kit plus 2 hours labour unless I can do it myself? Or maybe doing what others here have done, raising both stock needles, lower the clip, 46-48 idle jet. |

them`s blind corner one after the other, Haa :mchappy: Bit like the TT or a London dispatch rider :mchappy: crazy feckers. Go get one of them Gixxer cans like im doing on my project, they are cheap as hell in the UK, or got to you tube & search GSXR + DR650, they don`t need repacking, they are light as anything (2kg) & they look road legal. I just gave my heads a quick tickle up the ports, them factory restrictions don`t do the flow any good :no: http://www.lightwire.net.au/tenere/Porting1.JPG Only a couple of hours work will give you that snappy throttle response you crave, its not about BHP, its how it feels in your hand. http://www.lightwire.net.au/tenere/Porting3.JPG http://www.lightwire.net.au/tenere/Porting4.JPG Mezo. My 3AJ rebuilds here. |
mezo opening the ports up is fine dont make the inlet ports too smooth its the textured surface which helps make the fuel and air to mix better i've seen performance knocked off by over doing the port finish :innocent: the combustion chamber is normally fine just a de coke is enough to keep that clean :cool4: the exhaust ports can be as smooth as you like the headers are enough to keep the back pressure wave intact :thumbup1:
03XT600E dont waste your money on a dyno jet kit you are better off getting a handfull of jets and a book on carburetor tuning you will get more out of doing it that way than handing it over to a so called professional who will probably **** it up quite a few times before getting it back to just a fraction better than it was before taking all your money :rolleyes2: your hic up at 5500 rev is pretty normal for the mods you have its the secondary carb kicking in and is more than likely the main/needle jet than needs going up 1 size or the needle does need to go up a notch :thumbup1: |
