Shifer issue question
Looking for a little help/advice. I have a 2006 KLR originally with a locked up engine. It had been sitting for a few years. Luckily I got the engine broke free and took off the clutch cover to check the clutches for stuck plates (no problem there), am rebuilding the varnished up carb, good there. Then when I went to put the trans in gear to hold the engine while torquing the impeller shaft, I discovered that I could not get the trans in any gear. I have rolled the tire while pushing down or lifting up the shifter pedal, no movement (it moves up and down freely but will not shift the trans into 1st or 2nd). I even pulled in the clutch pedal while pushing and pulling the shifter and rolling the wheel, again no luck. Before I pull anything else apart, I want to make sure the trans will go into gear.
This may sound stupid (since I normally work on the old Kaw 900 and 1000's), but it does not need to be running and spinning the disc packs to shift??? Sorry for being lengthy, but I wanted to give a little background. Thanks for any advice!
