Oh, I'd have to disagree here, I installed a yamcharger on an apex before, and while it worked as expected, it would be no match for a stock winder.
Whenever I jump back on an apex(or an 850 or 800)from a winder, I can't help but think how doggish they feel compared to winder.

Well I'm headin to the UP in a few weeks, hopefully I'll have a chance to see how my sled measures up to the "competition". Gonna have a chance to see what my top speed is compared to previous runs on my secret high-speed testing road. Best previous pass was 130 mph (approx 117 mph actual) on the dreameter, Between my higher performance and soon to be installed overdrive primary, I expect to be well above that.

You should grind one cog off ur speedo gear mutch closer to acturate. I did mine i also run shaved clutches
I bet your sled will really impress...trouble is good luck finding a "Stock" Sidewinder out there as most have some sort of flash done to them even though they are claimed to be stock...trust me I know

I would like to see it against a modded winder. Something with the 11K rpm and gear reduction, the old style chaincase, the Ape's are just flat out fast! I would love to drive your sled macheater! I bet the insane throttle response is fun as heck!

Thanks for the vote of confidence fella's. Yes, I'm very pleased with how it performs. And whether it be a stock or modded winder, I'm still very interested to see how 180+ hp compare's with 200+ hp. I really think my machine will have a respectable showing, regardless of the outcome.
When I recorded that 130 dreameter run several years back, it was much closer to stock, having only a fix ramair lid, excell exhaust and pc3 with a less than perfect map. In all honesty it was probably only slightly faster than stock.
Keep in mind this is a trail machine first and foremost. It is set up as a trail machine and not a drag or radar sled. What it runs (top speed wise) in trail trim is what it runs. And I'm good with that.

Have you or anyone else ever experimented with cams? I would think that would be where the power is to be found, especially with an intake cam.

Cams are available, but, IMO are more of a race only item. My reasoning goes like this. I believe that Yamaha did a good job of choosing cams that would give good midrange and topend power for the Apex's intended purpose. Which is good trail performance. And given its weight, they felt it needed good midrange power. They had to be conscience of engine rpm and belt speed to give adequate longevity. IMO the Apex is in a fairly mild state of tune. Conservative fuel maps, and timing, and reasonable rpm. For the guys who dump crap gas in their machines and then go out and hold them wide open for miles. The factories don't like warranty claims, and they don't like unhappy owners trashing their product.
Would hotter cams give more power? Most likely, but, they would in all likelihood push the rpm's higher in the process and lose that all important midrange power. And now the belt speed is reaching even higher inefficient speeds without even further reduction.
Already been through this scenario with my street going Kawi ZRX12oo. The stock cams give great low and midrange power, but, sign off quickly at about 8,500rpm. Very low by todays standards. So when I did put a hotter set of cams in it, guess what; more power, but higher up the rev range, and a predictable loss of midrange. Bikes can get away with turning more rpm as long as the engine can take it. They don't live at redline like sleds do, and they don't have to worry about driveline speed.
An Apex is already close to making its peak power near rev limiter cut in. So you don't have a great deal of rpm to play with, maybe 800rpm at best before the limiter cuts in at about 11,200. So right about the time the better power is coming into play, guess what, end of party. Now can you eliminate or raise the limit? Probably, but your still stressing the engine more and pushing belt speed higher in the process.
All of these things can be overcome, but, at what cost, and with how much work? Its much cheaper and easier to get better performance through a power adder, and keep the belt speed and engine rpm at or near stock levels.
