Looking for those with personal or knowledgeable experience swapping the stock YZ head with a GYTR complete head assembly with valves. My question is regarding the oil squirter, there may be a correct technical term for it, but I was told by a Yamaha tech that Yamaha will add an extra oil squirt nozzle which requires splitting the cases, but some people choose to do without it. It's been 2 years since the conversation, but I want to say the logic was if running a high-comp piston + race fuel, must add the extra squirter. If running standard compression piston + pump fuel, don't need it. Application is 30+ B/Expert rider racing 10-15 times a year. or about 1+ race a month. Anyone out there have clarity on this?Thanks a lot!
