Hey everyone I am new to this site and it seems you can get alot of answers here so I figured id give it a try. I just bought a Yamaha 650 v star custom and the motor seems pretty stong but it needs another gear since most my driving is on the highway. It is shaft driven so you cant change the sprockets is there a way to change the gears in the transmission to get the RPMs down at highway speeds any suggestions would be nice Thank You

My wife just got an 08 650 custom. Ive been trying to learn about them. We did a J slam on it and lowered it four inches in the rear and put some phats risers on it to bring the bars back two inches wife is vertically challanged at 4'9" she can flat foot it now. Ive been reading on all the forums and ive not ran across anyone who has been able to change the gearing on them. I ride a Suzuki c50 and a guy in ohio came up with a way to swap out the gears from a c90. It reduces the gearing by 14% so now when I ride at 60 mph it revs like it use to at 52 mph. I really love it. You wont hurt that 650 running at highway speeds these motors are short stroke and can easily handle the higher rpms. anyhow keep surching maybe you will find an answer but ive never heard of any options. this pic was taken before the risers were put on. Thats my c50 in the back ground.

No "practical" way to change the final drive ratio
BUT
Riding slightly slower will lower the RPMs a bit.

Thanks for the replies I am still doing some looking around for some answers but another thing I thought of was looking for a diffrent ring and pinion gear that would fit then it would change gearing in every gear I think the bike is still too new to have parts like that for it but im sure with enough compliants someone will make alot of money with a set of aftermarket gears for this bike I know I wont hurt the bike cause it does have a rev limiter ive hit it. but it would just be nice to cruise at 75 or 80 without the bike screaming at you.
