What’s up everyone? I’m Dan and I ride a 2015 ZX10R. I’m here in Kentucky looking for ideas and tips to help improve HP and custom ideas for the bike. I have added a Austin Racing slip on exhaust with a K&N air filter. I had the ECU flash and Dyo Tuned. I’m at 190hp now. I’m wanting at least 200hp. Anyone with suggestions?

Hello mate welcome to the forum. There's a lot of folks here that can help with that power info. I don't know enough about the G5 yet, but i think without engine work your going to struggle to get 200WHP on the same dyno. But you never know. Maybe the right system and filter cou;d put you in the ball park.

"at least" 200... :lol: the gen5's struggle to make that much power. They need to be squeezed like a lemon! A gen4 will not hit 200 (on pump). You're going to need to invest in MR12, a sprint F2 or MWR WSBK filter, and another detailed dyno-tune. That should be good for anywhere between 8-10HP. Mind you, you're never going to be running that tune though on the streets. The fuel maps and timing for MR12 are completely different so you cant mix fuels, you gotta siphon it out each time you switch, there's no MR12 at any pump period, and it's like $25/gal.

Aside from that, you can port/polish and cam for like $3500-4K, that's good for, idk, about 12-15HP on pump. You can also get ceramic wheel+trans bearings and get (maybe) 1HP on the dyno.

Yea that last 10hp is really hard to reach. Thinner head gasket and mr12 would probably get you there. Also unless you're a phenomenal tuner and feel like tearing your bike down a bunch of times to re degree the cams then dont even bother with the kit cams because theyre really hard/picky to see gains with. Welcome and have fun.

>> confusion <<

Please don't misinterpret my tone here; I'm simply & sincerely confused on this thread.

A good friend of mine has a '12/Gen4 that was thoroughly built, tuned, and flashed @KWS. His bike has:


  • Ported & Polished Head w/High Compression Head Gasket
  • Race Cams
  • Upgraded Timing Chain Tensioners
  • K&N
  • Competition Werks Full Exhaust
And with all that, I've seen his 191hp dyno-sheet on pump gas. How is a '15/Gen4 making 190hp on a dyno with just a slip-on, a K&N, and a flashed ECU.?! :dontknow:

There's not a major difference in MR12 and pump gas maps. You can fill with MR12 and ride til close to empty. Then fill with pump gas, ride on the MR12 map for a few miles then switch back to pump gas map.

Dyno's all read different.

I think it's like, what, a +2 difference on top your base fuel map? I forgot what my map looks like off the top of my head but I remember it being like one or two numbers across the board. So you'll be running a little lean on MR12 with a base map. Not gonna damage your engine like an E85 map on pump would, but you'll be wasting all that money on little to no perf gains. MR12 likes to gum up too, so probably not a safe fuel to run if your bike is sitting for long periods of time.

Did some research after posting that and you're right, no ill effect from mixing :p

I entirely agree that getting hung up in HP numbers is an exercise in futility & that a Dyno's merit is in it's comparative ability to compare gains/losses after modifications, but to entertain the reality where a basically stock Gen4 with only a flashed ECU is honestly making 190hp at the wheel - I suggest is poor place to begin when trying to attain a 200hp dyno target. I guess if the true goal here is just to gain 10hp on that dyno and rather, not to achieve a true 200hp target, then I understand your premise & acquiesce. My logic is simply: if he wants 200hp at the wheel - like he asked for, I reckon he's got a long way to go. :beer2:

Your friend was bs-ing you with 190hp or the dyno was way off! A tune means everything man. I see bone stock bike derestricted bikes beat bolt on tuned bikes all the time. ALL the time. Your friend's tune is just bad if that's a reliable dyno. A gen4 can hit 190 without touching the motor. The port/polish/cam is good for conservatively 12HP. That with a thinner (assuming it's thinner) head gasket, a good tune, and something other than a K&N filter and you'd hit 205HP with 93 all day on the dyno.

Put a gen5 side by side with your buddy's gen4 and if he doesn't win a roll race his tune is sour. You live in South Florida? Talk to my good buddy Nick Russo @ NicksPerforanceTuning on Instagram or go to Ace Performance Tuning. They are the best tuners down south. I guarantee you, numbers aside, you will see a noticeable difference in the way your bike performs from idle to redline. I had my bike tuned three times and wasn't happy until I put my trust in Nick.

DIPAOLA <> I'm a little unsure if your last comment was directed at me. It doesn't seem to apply to me, but then you talked about S. FL so I'm guessing you're talking to me.

As I said in my first text, I'm just confused here. I'm new to all these new bikes as I've been outta the game for a minute, and I was simply unaware a Gen4 can hit 190 at the wheel without touching the motor. As explained, I was basing that off my buddy's Gen4 that was built, flashed, and dyno-tuned at https://www.kwsmotorsports.com/index.htm. I don't know them from a hole in the wall, but they are lauded so highly around here I had thought they were well beyond competent. I'm nearly positive CLCRacingAaron just had some work done there. As for my buddy's Gen4's tune being "sour", I don't know. I know it easily walks away from everything I've ever seen next to him... scarily easily. I'm not saying his bike is faster than Nick or Ace - I know it's not, but I do know he's the type that wants it faster so I'll refer those shops. He had already asked me for a referral to add nitrous. I was going to refer him to this guy "Willy" that is sorta legendary down here for his ECU flashes for top-end racing out on 27. Interestingly enough, when I Googled Nick's Performance there is a video of Ace vs. Nick via Manny vs. Willy
so I'm guessing we're both talking about the same people/shops. Thank you for the input, and I'll post up if anything interesting happens.

I appreciate all the advise from everyone. I think I’m just going to keep it the way it is and be happy. It’s not like I’m going to be drag racing. I was hoping there was a way to increase more power to the bike without doing a ton to crap.

As long as your buddies bike is walking everything it's next to then we can at least be sure the dyno he was on was undercutting him :p. I was only concerned because I deal with both Nick and Ace who do that kind of cam and porting work all the time and I know it's not cheap! $3-4000 worth of work only to make 190HP was concerning... if he can walk Gen5's he's good to go :thumbsup:

A dyno is a tuning device. The numbers dont mean shit. The difference in calibration, conditions, SAE/STD correction values will all give different numbers. If you are looking for 200HP give me your bike and $500 and I will give you a dyno sheet with a 200HP measurement with some quick changes to your tire pressure and STD correction.

This is the biggest BS discussion on a motorcycle forum with members across the globe. Might have better luck with an ignorant discussion like this in your local cycle gear.
