Ah, I was gonna say sell it and buy a 1st gen, but today is "nice" day. Get ahold of Pegscraper and see if he can fit a V-boost on your bike like he did. Might help you out.

The '96 - '01 Royal Stars do leave a little to be desired in the hp arena, don't they? A V Max engine will probably go right in, but there are easier ways. We already have 100ccs more to start with, and our blocks are heavier too. When the V Max boys want to build up a radical engine, they will start with a Venture block because the bottom end is heavier.

 

The V Max cams and springs are a direct swap into the existing engine. I've done it. Swapping cams and springs took me a day and a half.

 

The early Royal Stars have 28mm carbs, for which Yamaha ought to be slapped. The later 32mm carbs are a real easy swap. Here's the article I wrote about it, hosted by this very board. 32mm carb swap If you're interested, I can make the adapter plates and mill the intakes down for you. I've made a few sets for people. Once I had all the parts assembled and ready to go, this swap took only an afternoon from start to finish.

 

Check the dyno sheet in the article. The cam and carb swap together will give you 90 rear wheel hp, about 15 hp more than the newer Ventures and RSTDs, or about a 50% increase over what you have right now, with zero drop in gas mileage doing it. That's huge, and it's definitely worth the trouble.

 

I did also have the V boost system in my bike for a while. Actually it's back out now, and the parts would probably be for sale if someone were interested. I have my eyeballs on something else, and both won't fit at the same time. Because even the 32mm carbs are still too small for this engine's displacement. There's more potential there yet.

 

Then after that, get the D3K ignition module and swap in the V Max rear gear ratio. They will make a good difference too.

 

There's a set of 32mm carbs on ebay right now, and not bringing much at the moment either.
