I have a 07 700 that still has good power and runs great but….I am burning oil. It burned 2 qts in around 800 miles. I plan on doing a big bore kit and going through the valves after my trip to Taylor Park CO in July. The question I have is do you need to remove the motor to do the big bore kit and valves. How hard is it to remove the motor?? do the clutches need to be removed? Do you need any special tools? I plan on ordering a Yamaha service manual to assist with the job but I am looking to see how hard of a job it is going to be ahead of time. I planned on doing one of the 727cc kits with the 11:1 comp from ebay. It has a fuel controller and an exhaust on it already.

Thanks
