does your x500 " growl" when first taking off??

The Jcosta looks like a very cool var. I have read loads of reviews on other forums/site that all agree it works better on a light 4t engine/scoot than on a heavier 4t or any 2t. The consensus that I have seen is it wears too quickly. However the operation is flawless. Perhaps w/ a few more years under their belt it may replace the ramps, and rollers we all use but for now the pins wear too fast for the every day Joe. (as the pinns wear the ramps do not close as far)

I tried to find where I read the Dr. Sliders for the 500 were discontinued but I can't find it now.  I don't think I dreamed it, though.  Something about them coming apart because of the power of the engine.  Gonna look around again and see if they're available anywhere.  Sorry if I've given wrong info.

Not at all,  about a year ago I had read about a seperation of the casing from the barrel. I posted about that also not remembering what the exact case was. I hav heard/read nothing of that nature since. http://www.martinracingdealer.com/CategoryProductList.jsp?cat=Parts+by+Type%3ANylon+Sliders+and+Rollers&offset=100   This page has them for the 500 in lots of weights.
