Heres a shortcut , leave the throttle body , throttle cables , airbox on , you can disconnect the intake side from the black rubber block that attaches to the head , just 2 allen key bolts , there is enough flex in the intake boot to push it out the way and slide the head up. These tech videos will help so many . Keep up RMATV

Fantastic video! I have had a few "bad" experiences as a teenager trying to do mechanical work on my mc and decided that "this is not for me". Now, 40-years later there is something called "youtube" and I have decided that I'm gonna learn how to do this! I have seen other videos and reflected on the dirt and dust on the frame above an open motor and wondered... Thanks for straightening that out! :)

How to know when to rebuild
@rmatvmc3 жыл бұрын
Using an hour meter is a great way to track engine hours and to use as a guide when doing recommended services. A compression test and/or leakdown test are 2 of the most common ways to track the wear on your engine and what components might be might need inspected or replaced. We have videos on both procedures that you can find below.

50 hrs is essentially a safeguard. not always necessary but anything past 50 hrs generally the motor starts to loose power/ compression and also more likely to blow.
@paahtopro39503 жыл бұрын
@@nate.1623 it doesnt lose any compression or power. only if air filters is not well maintained some small sand or dirt particles migth get in the cylinder and wear out the piston. it is quite safe to do 150-300 hrs on a piston depending on your riding style. but anything after that the risk that its gonna blow gets higher
