Clutch needs to warm up

    On my 07 NE5, I've noticed that the clutch doesn't fully slip in until it gets warm. Is this normal? Does the partial engagement hurt anything?

    Just to explain...I start it, let it run for a minute to get the oil going and ride off. It moves but the clutch doesn't "slip in" for about 200 yards. After that, it's fine.

    Hi Peter, Does the clutch slip and then enguage, or is the clutch sticking and won't slip at idle?

    Have fun,

    Peter here is a previous post about the clutch and speeding up the break-in process.
    Many asked if it is normal for the clutch to slip during the break-in period.
    The answer is "yes", and I will gladly explain how to speed up the break-in process. When the clutch is new, and the shoes & drum are getting to know each other, only 15% of the shoe surface is touching the drum. As the break-in process continues more of the shoe surface will contact the hub, but I don't like to wait [approx. 50 miles]. I am going to tell you how I do it, but check with your dealer to make sure my method doesn't void your warranty. After the first 10 to 15 miles, I apply the brakes, rev the motor for a few moments. I then remove the clutch, and using a Dremel grinder, I remove all the "glazed" areas on the shoes. I install the clutch and repeat the process several times untill 90 to 95% of the shoes are contacting the drum. The end result is a clutch that "locks" completely at approx 2200 RPMs.

    Have fun,
    Quenton
