Front Pulley Change

In another thread I was asking for help in changing out the front pulley wheel, let me just follow up by saying unless you have the proper air gun, don’t bother trying it yourself. A ½” ratchet with 30mm socket won’t get the nut to budge! Long story short I took my bike into the shop this morning and they swapped out my stock 31-tooth pulley wheel for the 30 tooth (off of the VStar 1300) and only charged me $41 to do the swap. First thing I checked before riding off was belt tension and wheel alignment and they were perfect.

Results: totally awesome & highly recommended. Best way I can describe it – this is the way the bike should have been set up from the factory, it just feels right. That huge gap between 1st & 2nd is gone (you know when you are behind cars and moving too slow to be in 2nd but 1st winds the motor up). The shift between gears feels more natural, I don’t have to run the engine up as high shifting from 2nd to 3rd to avoid a lugging feel. Obviously it’s much quicker. Haven’t had a chance to do a top-end speed run, will do that soon when I have time to travel out to the back highway roads.

I did do a speedometer check however. BTW I’m still running stock tires, only have 4,400m on the bike, plan to burn these off this summer and go to 240 rear with matching front. So I tested my speedo right after purchase when I noticed it was off and found it to read +5-6mph faster than what I was actually traveling. This was consistent with everyone else’s Stryker. Just to re-check, yesterday I mounted my Garmin GPS and when the Stryker speedo read 70mph the GPS showed 65mph. So +5. Today after swapping the pulley wheel I tested again and now it’s at +7. Speedo reads 70 and GPS reads 63. Speedo reads 80 and GPS reads 73. From what Shane and some of the guys are saying, going to the 240 or 250 rear should correct the speedo issue. Looking forward to that..

Great to hear you are as happy as the rest of us that did this Mod. Good going SD!
Yeah thanks 11, and a BIG thank you for being the 1st to do this mod create the thread. Good call!
OK, I'm officially doing this MOD! How much is the pulley?
Do you mind taking a picture of the belt tension window to see which hash mark it's at and the axle alignment spline marks?

Silverridge- I bought a genuine Star pulley wheel and paid $200.
Usmarinedelta- here are the pics you asked for. As for belt tension, it should move up about 1 mark with reasonable finger pressure. You can see the before and after pic here as it lifts about 1 notch. As for rear axel hash marks, here’s a pic but it really doesn’t matter as long as both hash mark sides are even.

Highly recomend this mod!

You my friend are awesome. Thank you so much! I've been looking on ebay without luck. Now for your opinion on the 1st gear bucking, is it still there and noticeable? Also do you have auto tuner? If this will smooth out the bucking/jerking feeling I think I might do this down the road, thanks again sdsting!

From searching the forums people say the belt has to be 5-7mm with 10lbs of pressure and each line represents 5mm so aren't you over 7mm or am I missing something? Mine came from the dealer brand new just like yours as far as the hash marks go.
Thanks to both WOLFStryke and sdsting for the prices! Heading to the dealer this morning to order the pulley!

Personally I wouldn't be using a finger to subjectively guess how much pressure you're applying to the belt. But if he's truly applying 10lbs and the belt raises just past one line(5 mm worth of travel), and one could visually estimate to be around 7mm; so it's right on the mark.

If you need exact measurement then get a gauge for more precise calibration. Me, I just push and use my judgement.

Looking for one of those pulleys (Yamaha STR-4WM99-10-30) but can't see spending dealer price for it. JMHO
Mike – I didn’t adjust the belt or allign the wheel, the shop did, I’m just checking the belt tention with my finger to make sure that it is consistant to how it was set before.

Usmarinedelta – no I don’t have an autotuner, I have a power commander. Here is the tread on my mods and how they were done http://www.yamahastarstryker.com/18-mods-accessories/3438-stryker-dyno-last.html
Curious... what shop/dealer did the wrenchin?

Ok, I see lee's did dyno work. Did they also do the pulley change?
muchas gracias

Sting, your scoot is sooo badazz! seriously you have balanced the looks and performance well without overdoing it.
Good job Terry. You should get of the line quicker and a couple tenths faster in the 1/4.
Curious to see how top end goes?

240 dropped my spedo 4 mph, almost right on.
Ordered my pulley from the dealership. Should be here by next Wednesday. Really looking forward to my Stryker being quicker out of the hole!
I've looked at a couple threads about this a few times and it's been in the back of my mind. Well browsing through Ebay last week I came across a used pulley with a ridiculous price of $9.99 and buy it now at that. So of course I did. I figured at $10 plus shipping I couldn't go wrong! I'll wait till I get a few miles on the bike before I change it out, chance to see what if any belt stretch there is and I want to be able to feel the difference.
Nice Wayne!!

How much was the total from the dealer may I ask?
