i just got my 250r motor the other day to my project quad i'm working on, i won't to tear it down to see if anything needs replaced. are there any special tool i should get? thanks

 

A good compression tester. Preferable a Snap-On, Mac, or Cornwell. A Craftsman will do, but I prefer the Snap-on.

A flywheel puller, the Motion Pro one. There are some other manu's that make them and they use crappy material, they strip out or break.

Again another Motion Pro product, the Clutch Hub/Flywheel holder. Makes dis-assy easier, unless you have a 1/2" impact in your pocket at all times.

A quality torque wrench, again Snap-On would be best, but a Craftsman will do too. Make sure to be nice to it so it stays in calibration. Reduce the torque to zero or less than 10% of the capacity of the wrench(250 ft-lbs. wrench, loosen to less than 25 ft-lbs.).

A dead blow hammer, greatest thing to get stuck cylinders off.

A 8mm and 10mm die to chase the threads of what you take apart. Clean theads torque more accurately and dis-assy is again made easier.

Time and patience. Have good lighting. Eat a snack before you start so you can stay focused. Make sure everything is clean before you take it apart. Foamy Engine Brite and warm water scrub to keep the debris out of your engine.

 

Dont forget the assembly lube :-) I also saw a piston pin puller in the dennis kirk for like $25. granted you dont need it but I usually have a heck of a time gettin the pin out, usually gotta "reef" on it with a dowel or something... not good for the rod.. I plan on buying one soon.

 

thanks i just order the flywheel puller. i alreay had most of the stuff. i plan to get a compression tester. thanks agian

 

I would also suggest a good Hand Impact driver.
