I have removed the seat to replace the fuel tank with an new larger one. I also have a XR's choke plate to replace the stock choke plate. Do I need to remove the carby and what is the best way to access the choke plate? The plastic surround from the airbox to the carby inlet has a lot of screws so it doesn't look easy to remove. Is it best to remove airbox etc? Rode it on two trails last week, over 200km, had a blast. Took it off a small jump ramp, crashed and broke a brake lever, but the bike is good. Having a blast, just need to get these jobs done and back onto the trails.
