Title: Front Pulley
Post by: t84a on Mar 13, 2016, 06:13:27 pm
I found a potential company to produce a 30T front pulley but I need to send them one. The Stratoliner and Roadliner are the same. If you come across a used one somewhere, let me know.

No idead. This company makes sprockets for Harleys (of course). The guy didn't give me any idea on cost or minimum order. I posted the same request on a Stratoliner forum so who knows, maybe someone has one. Thanks

Cool, I would def like to give one tooth down in the front a try !

Liners and Raiders are the same at 31.  The difference is the rear pulley, but that means the belt needs to be changed.  He needs the spare to send so they have the dimensions for the offset, width, center hole diameter, how it's mounted, etc.  Once they have the hub dimensions they could make 30 and 32 tooth pulleys, and they could be changed without buying a belt.  Theoretically. Hopefully. 

If I could get a 30 tooth for under $90 I wouldn't even think twice.  At $150 I'd probably still be in, but I might wait to see how other people like it.  Over $250 I'd look for a Liner pulley and belt and stick with Yamaha quality.  If I made a change at all.  Then again, if the front could be swapped without removint the rear wheel it still might be worth it.

Yeah man I got ya ... Don't know why but I had a brain fart for a second , thought the front was the difference, but your 100% correct it the rear!

No doubt , for $90 I would be in big time , 1 down on front would give our bike a better low end for sure ! And you could run the stock belt like you said , so that's a plus !

Honest question.  What difference is 1 tooth going to make?  I would think it's so we can use the cheaper belt with 1 less tooth or is it for those who like to street race?

Don't know how big a difference it will make on the raider ...

But on a sport bike it makes a good difference in low end and acceleration !
 1 down on the front is equal to three up on the rear on a sportbike , I would imagine it would be close to same on raider

I forget what the Raider and Liner rear pulleys are, but it's all a matter of percentages.  More torque multiplication means more wheel power.  The bigger the difference between front and rear, the more low end and acceleration.  The closer they are you lose low end but gain more top end as long the engine makes enough power, and lower cruise rpm.  Of course you can go to far to extremes either way, but 1 tooth up front is enough to make a difference you can feel.  It wouldn't be huge on a dragstrip but you might 2 to 4 tenths of a second in the 1/4 mile.  You might lose 1-4 MPG too.  If you run heavy on the freeway and would like more passing power without downshifting a smaller front or larger rear would help.

1 up on the front would actually give the bike a higher gear ratio bro not lower !

Up in rear is lower ratio , down in front equals lower ratio and more acceleration also

Speaking of front pully, I have a bit of a tidbit to throw in.

I bought a 2004 Warrior used with about 25,000KM on it. Rode the shit out of it for the first week, then noticed a clunking sound coming from the rear. I thought it might be the belt worn out and slipping. After spending $900 on a new new belt, tire, and rear wheel bearings at the stealership, the problem was still there. Losing confidence in dealer, I investigated further. What I had discovered was the final drive shaft was stripped and the front pulley was slipping on the shaft. The seller had to of known because some assclown tried to fix it up with what looked like JB Weld. Lovely. Now it does have to go back to the stealership. Was told the shaft was on back order and no idea when available. With that said, I went to a bigger city that had a HD dealer and looked around. Nothing there I wanted to ride so I went across the street to Yamaha. I walked in, asked if they had a Raider. Salesman looked at me kinda funny because I am only about 5'7" and 140lbs. He directed me towards the bike, I sat on it, and immediately told him to write it up. He was like "really, you got financing?". I said "ya, really and showed him a certified check from the bank". Easiest sale the kid ever had.
Not even a week after I bought the Raider, the local dealer called me to tell me the bike was fixed and ready to go. I decided I would keep the warrior as a second bike and my son could ride it. Long story short; after he rode it a few times, I discovered a huge piece of the lower steering stem where the lower bearing race is seated, was broke away and gone. I attributed this to former owner either crashing it or laying it down a couple of times as the steering stop was broken away as well. Here is what really hurt. I paid $4500 for the bike, another $900 troubleshooting pulley, and another $3200 to replace pulley. I cut my losses and sold it for $3000 and wrote right on the transfer papers that the bike was unsafe to ride and made buyer very aware of consequences if it is rode without being fixed proper.

Anyways, back to original point I am getting at. My conclusion, I believe the pulley shaft was stripped due to previous owner(s) riding habits. The Warrior and Raider make a shitload of torque. I think the previous owners were hitting the throttle too hard as well as slacking off hard. The minuscule freeplay/tolerance between the splines of the shaft and pulley, combined with hitting it hard, eventually stripped the shaft. For that reason, and thru my trials and tribulations with the warrior, I try my best to roll on the throttle and not 'bang' the drive train. Super hot starts off the line are easy enough to do without 'hitting' the drivetrain. So with that said and being the Raider makes more torque than the warrior, I have far more miles on my Raider than what was on the warrior, and knowing the previous owner, I know for fact I have ridden the Raider a lot harder than the Warrior ever was, and there is no evidence of the issue. I believe it was due to 100% rider technique.

Food for thought.

It will make a difference if you have gone to the taller 240 rear tire. It will get the gear ratio back to the original spec.

Interesting.  The original specs?  That means the speedo will be off again.   :thinking:  I would have thought there would be more difference than that.  I never felt a loss of power from the 240.  I'd expect to feel a gain form a 30 tooth pulley.  If the difference is no more than the difference between the 210 and 240 it's not worth it to me to change.

Since none of us have done this Mod yet I'm kinda assuming here... but I think its gonna make a pretty decent difference with a 30, your rite its gonna play with the speedo reading but the lower gear ratio will be a fair trade to me!

I swapped many front spockets on my sport bikes and going down one make a good difference on them , so I can only imagine that with the torque the raider puts out , it will be a good boost down low.

As long as it doesn't kill the cruising rpms to bad I for one will do it !

I'm not sweating it.  My guess is it won't be quite as big a difference as a Liner rear pulley but will be more than the difference of the 210 to 240.  I think it will be noticeable.  I don't think it's gonna be too radical for the slab, either.  If Liners can do it then a geared Raider will have no problem.  I just like the idea of being able to change gears and not needing a new belt.

That's it Bill,  when I was racing I had  12, 13, 14 and 15 tooth front sprockets short course arena crosses I would use a 12 or 13 and could launch in 2nd gear but you do have to shift gears quicker, big outdoor tracks the 14 or 15 so you don't have to shift  as often, it will make a difference really looking for this to happen with a 30 front pulley

Less rpm at cruising speed => the only mod that I know, is to use a 61T HD pulley and 1 1/8 belt. I had this combination, but the belt broked and I have changed back to stock system.
But maybe the drop from stock 66T to 61T is too much. So, I would like to have a 64T rear/stock front, or a 32T front/stock rear (same ratio in both cases)...

Does anybody has any hint ? 64T rear or 32T front ?

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.

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.

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.

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.


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?
