For those of you familiar with the V Star 1300, you know it’s very sensitive to accelerating at low speeds, causing the bike to jerk a bit if you’re not careful (“throttle snatch”).  In addition, the standard handlebars are NOT the most comfortable for many people.  The grips are too far forward, resulting in the rider having to lean into them and/or lock their elbows.  This makes for an uncomfortable ride.

Well, to combat the throttle problem, there’s a product on the market that purports to smooth this jerkiness out.  It’s called the Throttle Tamer.  What this does is essentially smoothes off the first part of the cam that the throttle cable runs on so it has a smaller diameter.  This results in less cable travel during the first part of throttling up.  The below picture is from a review on

The standard throttle tube is shown on the left, and the Throttle Tamer tube is on the right.  Note that this is NOT the model for the V Star 1300, but it’s the best image that I could find that shows the difference.

The second problem (the handlebars) is another topic frequently discussed on the V Star forums I visit.  The most common solution to this is to replace the handlebars either with bars from another model bike or aftermarket bars.  Most people end up replacing them with the handlebars from the Yamaha Royal Star Tour Deluxe (RSTD).  These bars are slightly narrower and come back about 4” more than the factory bars.  Yamaha finally recognized the fact that the OEM bars were uncomfortable, and made a change to them for the 2010 model of the V Star 1300 Tourer (there was no 2010 model of the standard V Star 1300).

The outermost bars are the OEM bars for my bike, the middle set are the new 2010 OEM bars, and the lower set are the RSTD bars.  You can see the RSTD bars come back and in quite a bit more than either of the OEM bars.

Well, these two problems were the target of my latest motorcycle modifications.  I ordered the RSTD handle bars from SC Custom Cycle (see link to right).  A disadvantage of the RSTD bars is that you cannot use the grips/end weights from the OEM bars with the RSTD’s.  Therefore you either need to buy RSTD grips and end weights (mucho $ for them all) or go with an aftermarket grip.  I chose the latter, getting Kuryakyn ISO grips and end weights from SS Custom as well.

Well, since I was going to be replacing my grips (and subsequently my throttle tube) anyway, I decided that it wouldn’t be THAT difficult to do my own “Throttle Tamer” style modification on my new ISO throttle grip.  So I dug out my Dremel and cautiously proceeded to do just that (after all, they were more than $60!).  Here’s the result…

A little difficult to see because it’s all black, but if you look carefully you’ll see that I ground the first 50-60 degrees of the throttle cam into a ramp going from the diameter of the inner tube to the diameter of the rest of the cam.  This is effectively identical to what the Throttle Tamer does, for zero cost (well, SOME cost, since I had to buy the new grips anyway, but this could have been done with the OEM grips had I been able to reuse them).

Replacing the handlebars was a little more involved, but I followed the directions given on the forum, and all went well.  A few of the steps were irrelevant as the guy who wrote the article was moving his ISO grips from his old bars to his new ones, but the bulk of the instructions applied.

The end result is that I can now sit fully upright in my seat, and I’ve eliminated MOST of the herky-jerkiness of accelerating at slow speeds.  I hope to take a ride this weekend to see how much more comfortable it will be not having to lean forward and lock my elbows…

Good luck and ride safe,
