    Welcome to the forum. Len aka chacal sells lots of parts for XJ owners here. You can email him on info@xj4ever.com and checkout the parts for your bike by clicking on the XJ4ever logo on the top right of your screen.

    Welcome, but a word of caution - replacing the exhaust will not stop your bike starting due to needing rejetting - you have another issue.
    Oh poo, misread, so you removed your airbox as well - stand by for some major "you don't wanna do that".
    My answer is the same, but to a lesser degree, no airbox and a different exhaust won't stop it running from cold. Make sure the PRI is working on the petcock...

    Pods should not prevent starting also.

    Battery condition? Check while cranking should stay above 10V, anything lower and spark will be too weak

    I've worked with Jets-R-Us in the past, reasonable but make sure your address is correct if you're using PayPal... found out the hard way they will only ship to that listed address and lost a set of jets because PayPal didn't update despite making the changes when I moved.

    If you can't get it started after cutting the airbox up and modding the exhaust the problem is not jetting... this is only the start of your tuning nightmare.

    And if you can't work out why an engine won't start there is little hope of you getting it anywhere right on pods and 4 to 1...
    Seeing as it's been 3 months since the op last seen I guess this post is for others as well as the OP, if he comes back..
