Well another small product born out of necessity for the R1 engine. this adapter will allow you to run a 1/2" or 3/4" inside diameter pully off the end of the R1 crank which can then be connected to a fullsize alternator of your choice. it will fit 2004 to 2008 Yamaha R1 engines. this will be a great addition to any R1 powered UTV, it will give you the much needed power to run all of the necessary accessories like race radios, off road lights, fuel pumps, and whip lights without worring about drainning your battery.
This kit is easy to install and will leave room for your engine mounts. everything you see is included in te kit except for a pully. due to the end users requirements i felt the added cost of a pully that would not suit all was not needed. there are lots of companys that can provide you a pully at the size of you liking. i included a 1/2" to 3/4" i.d aluminum bushing to allow more choices in pully sizes.
I would recomend running a Power Master alternator due to their claim of a 15,000 RPM max which will be ok for these high revving engines. you can reduce the rpm with different size pullys to keep the alternator from spinning in its high rpm range. Summit racing has ok deals on them, but drop shipps them so shipping could take a couple weeks.
i normally dont make products and sell them but figured this was something a few people need and i wanted one so i had a few made.
i am selling these for $212 shipped to your door.
