You're right. Sorry. Its it's the Liner guys who want our pulleys. Thanks Dave.

    Here's the pulley and sprocket teeth count and ratios for the Liner, Raider, and Warrior.

    I actually checked into doing this about 6 months ago.  We source out some of our more custom machine work because it's cheaper for us than having million dollar machines to maintain.  I was told they could do it of course, however the initial cost of making the first one, & then having it test fit & tried out (which I volunteered to do), plus any revamping of the initial part was estimated at about $5K......this is for a 1 piece machined billet cut pulley.  I was actually expecting more since some of our 1 off pieces cost around $15K-$20K to have made.  Basically I was told it would take a "payment up front order" of at least 100 at a cost of $150 apiece for them to even consider making the part.  Right now I'm in the process of trying to find a vender that will buy the patent rights to the pulley & market it under their name.  By doing this, a big name vendor can put in an order for say 500 & get a discount on initial cost because of quantity ordered, which leaves them room to make a profit.  So far no luck.

      Pulley swaps on the Raider, etc won't sell. You have to replace the belt as well and right now aftermarkets are not really exact fits even though they work. I worked with a company to try to work something out but I don't think people are interested in a $500 upgrade where you have to remove the rear swing arm. The front pulley would have been the answer but 1 tooth wasn't enough.

      By going only 1 tooth down in the front, you should be able to use the stock belt.  I replaced the belt on my Raider with a S&S/Gates High Strength Final Drive Belt, 14mm 133 Tooth - 1-1/8" & it fit fine, had plenty of adjustment left.  When going with an aftermarket belt, your choice is either a 133 or 135.....Yamaha really F*%# us with that 134 tooth belt.  The reason I went with the 133 vs the 134 was because I figured the belt would stretch some over time & wanted to have plenty of adjustment left vs a 135 that would be right at the end of adjustment.

      1 tooth down doesn't make a big enough change.

      I woulda thought 1 tooth less in the front would give a good bump in acceleration vs our stock 31 tooth.  I know the rule of thumb is commonly going down 1 tooth in the front is = to going up 3 in the rear.

      Honestly, I'd be more interested in a 32T pulley (one up) to lower RPMs on the highway. The Raider puts out plenty of torque as-is and the extra tooth up front would help compensate for no 6th gear.

      1 tooth only changes the RPMs by about 133 at 4000 RPMs.

      Ever think about a 3d printed pulley for fitment?  I know you wouldn't be able to road test it, but you could verify design.

      Interesting, we have a 3d printer here at work.  I'll check with the guys & see how long it would take to create it.  For all the guys that want a bigger front pulley, I'm 99% sure a bigger pulley won't fit.  The 31 Tooth has barely enough clearance, so a 32 tooth would be a stretch & a 33 tooth is definitely out of the question.

      So is there a 30T front pulley?
      There are only 10 types of people, those who can read binary and those who cant.
