JT Sprockets JTR1304.38 38T Steel Rear Sprocket
Product:
JT Sporckets – 38 Tooth Sprocket. Part #1304.38
Affordable, simple, and straightforward. This sprocket is a little heavy, but I'm installing it on a cruiser and not a sport bike. The quality of the steel is superb, my first impression was that this sprocket was going to last quite a long time. Installation was a breeze. I loosened the rear axle nut, lifted the bike, then removed the rear brake connections and then the rear axle. Because I installed a new 122 link clip type master-link chain at the same time I used a Dremel tool and a small grinding bit to grind off two of the stock chain rivets in order to break the chain with a simple flat head screwdriver. Once I unbolted and removed the factory sprocket off of the stock wheel, the new 38 tooth JT sprocket aligned and fit perfectly. The entire process of removing the wheel, replacing the sprocket, and then reinstalling the wheel with the new chain linked together took less than two hours. On to the important part of the review, on the first ride, I noticed the difference immediately. Technically some zip may have been lost off of the line going from the stock 42T to the 38T but I felt it was hardly noticeable. The zip is easily compensated for by rolling the throttle and holding each gear longer. My first time on the highway with the 38 tooth sprocket I immediately thought to myself: "why wasn't this the stock sprocket / gearing for my bike from the factory." I no longer have the feeling for another gear when cruising down the highway over 55mph. With this 38T sprocket as I am entering the freeway I ride up to cruising highway speeds of 70mph or so in 4th gear and then shift into 5th as if it were Overdrive. I can now cruise down the high way at 70mph to 80mph (some speed limits in Texas are 80mph) and the engine sounds like one would expect it. Putting down the highway. Before the engine seemed over worked for a V Twin engine when cruising at 60mph. A 38T sprocket is a must do modification for highway riding. Shortly after changing to a 38 tooth sprocket I replaced my clutch springs with stiffer ones and modified my timing to advance it approximately 4 degrees. All of the above modifications mentioned are what I consider must do mods. JT Sprockets makes high quality steel sprockets in a number of variations to meet your needs that will surely last quite a while.
