Ok- I got an idea from the Raider Forum about changing front pulley to a pulley with 1 less tooth to increase power to rear wheel. This will help alot especially after adding larger diameter rear tire. So I counted the teeth on the Stryker stock front pulley- 31 teeth. Called Brent at Tejas and he helped me do some research and he found and physically counted that a VStar 1300 front pulley has 30 teeth. This will give bike a -3.33% Ratio change from a Stock 2.258 Final ratio to a Modified 2.333 Final Ratio. I must mention that Brent went out of his way to help me with this. Also he checked and found that both bikes take same belt, so the length of belt should not be an issue. He was absolutly fantastic to talk with on the phone. Extremely Nice Organization he runs. So I ordered the 30 tooth front pulley from Tejas and will be installing it once I receive it. Next will be getting nice enough weather to ride Bike on saltless! roads to try this out. Part Number for the VStar 1300 front pulley is 3D8-17651-00-00. All Star motorcycles come with 70 tooth rear pulleys except Raider which has 66 teeth. You would have to have more teeth than stock on rear pulley to achieve same results, but only rear pulleys available are for a HD and have to be Modified to work on Star Rear Wheel.
