I have a 1994 XR650L that needs second gear. I also have a XL600R parts bike and XR600R suspension setup. I'm combining the two and building a beast. Here's my plan. Swap the dual carb setup, the head, airbox, cams, timing chain, valve cover, decompression setup, right engine side cover and all the kickstart parts from my '85 XL600R. The dual carbs and airbox fits by using the rear shock from a '87 XR600R with it's remote reservoir and smaller diameter. The remote reservoir will mount in the XL's empty battery box. I have already swapped on the XL's 1/8" larger header and XL Supertrapp exhaust. It will be getting wrapped. It is a direct swap for a XR L header. I still have a spare XL header too. I need to find out if second gear from the XL will fit or if I should just use NX parts. I also need to research adding the kickstart and head swap. I will be tearing down the engines very soon. Are there any other good parts I should swapfrom the XL like ignition or such? Any good links for the second gear repairs, a factory service manual pdf or any other input would be great.
