I am new to this forum and recently purchase a 2003 RX-1.
Love the sled. I would like to do some fine tuning to the performance.
I read in the Tuning info about changing the primary sheaves.
Does any one have the part number for these? Or maybe the year that they are from?

"Tuning tip number #1 ......... install the primary sheaves off of a VK 540 (Viking)..... they are 12.5 degree vs 14 degree stock..... we are finding that it is grabbing the belt much better.... also will produce more top end hopefully by allowing the belt to have more travel (sheaves close closer!!!!!)...... try it out... the sheaves are not very expensive... we ran the stock RX-1 primary and another stock RX-1 primary other than the sheaves and gained 3 mph in 500ft of grass... enjoy.... :-)"
 

Head over to the thumper side,they have all the RX-1 info.(RXwarrior owner myself,still pulled 111mph on GPS few days ago,all stock:sled1:

Sorry little slow on here yet. Not sure what you are talking about.
I just had mine out a couple weeks ago. Could only get 90 mph out of it.
Figure I need to make some adjustments.
