Hey Guys, I am attaching the email I sent to Josh (Aeromyst) from The Scooter Garage. The email explains itself.
"I received the engine today. Thank you Josh, and THANK YOU for the sliders! What a pleasant surprise. I've never tried them before, and I don't think I will ever go back to rollers. Trying to "balance" the engine/pipe, and the Var/driven pulleys has been as you know trial, and error. The 7gr sliders have pulled it all together. I NEVER would have thought to try them. THANKS!!!"
I have been up/down in roller weights, and have not found the "balance I was trying to achieve. I asked J. if he had anything besides the run of the mill brand rollers so I could try something else. He does not really tune using the weights I was seeking so the end of that. Along w/ my purchase he included a set of Dr. Pulley 7gr sliders. BINGO!
