    Thinking about putting my cobra pipe off my parts bike on this one, my question is what size main jet will i need to go up to? And I won't be using the full header pipe I'll be using the cobra like a slip on some what

    • If it's just a slip on you shouldn't have to jet it.

    • It's a full exhaust on other bike but I'm gonna cut it and put it on the stock header pipe on this bike, so I won't need to go to bigger jet?

    • Can you use the carb off your parts bike it may be tuned for the cobra pipe already. I didn't jet mine when I put the full header pipe and muffler on. It runs a tad lean but not enough to mess up the idle or power. If you jet it with the full pipe you will get a tad better throttle response.

    • It already has carb off parts bike on it lol

    • I have had a cobra on mine for a year and a half and still haven't burnt any valves up so I think the flow is not changed a whole lot it's just more the design for the sound. Gives a tad more breathing room but not enough to mess anything up

    • But it needs rebuilt it won't idle
