No denying things like this help. if you've never owned a 110 before, the race cam does a TON for power delivery even on stock bore.

However, Is that 2HP gain a butt dyno, or did you actually dyno the bike?

 

A race cam would do little real world on an otherwise stock klx110. The bike just does not have enough bottom or part throttle power to give up any and come out ahead. At 190# I could never keep it singing that high riding off-road. 2HP is a very good estimate on a 7HP bike. The change is very noticeable. I am trying to line up a dyno now. I have seen a ton of HP claims on this site and zero actual dyno sheets,lol. I am sure the gain is there. This ain't my first rodeo.

Do you have a dyno sheet to quantify that TON of power?

 

Since we're getting technical here, cowboy, I didn't say "TON OF POWER" I said it does a "TON FOR POWER DELIVERY". But hey, I don't own a dyno, so what do I know? (hint hint)

But, i'm sure that revving it on the stand and claiming a 2% increase signifies that this may be your second, or third rodeo.

Also, just curious, what is the ambient air temp and correction factor for your butt dyno? You know, for science.

 

Surely a TON for power delivery would show up on a dyno, no? Since we are getting technical what is required to see that ton? Pipe? Carb? Pod filter? Porting? Labor? $$$?

You show me your dyno,I will show you mine. Your the one who called me out on the dyno.

 

A ton for power delivery would show up on a dyno. Especially when changing the profile of a cam, where it does what cams do..power delivery.

Whats required to see that ton? Put the bike on a dyno. Run it. Swap the cam. Dial in your AFR, and run it. Compare graphs and use the provided data to give a brief summary of what occured.

I already said I didn't have a dyno. I called you out on the dyno because you claimed a HP gain, and yet you don't have a way to measure that gain. Thats all i'm asking. HOW DID YOU MEASURE YOUR CLAIMED GAIN?

 

I said I estimated it and you made fun of me for demonstrating the throttle response. The only reason I did was to show the bike was running clean with the mods. For real world performance the cam needs to be matched to the CC's and head/intake porting. Adding a bigger cam to an otherwise unchanged combo will do nothing real world if if the cam was big enough to begin with. In the case of an otherwise stock KLX 110 that is the case. You may see a small increase in peak but loose a bunch in the curve
.

 

chubbs, I made a video of a demo ride if where where sharp enough to notice. That's all I could do until I get to a dyno. Like I said, how many dyno sheets are posted around this place?

 

KX kid I'm with chubbs that your title made me interested in seeing the dyno results but all you have are guesses with no empirical data. I know these mods make a big change(Ive done them all myself in the past) but 2hp is a big claim. You can even get an estimated hp gain by doing a timed pull before but again the title is very misleading as nothing like that was done.

 

I have an appointment next Wednesday on the dyno... Nothing misleading as far as I am concerned. Maybe I know a little bit more about making HP than you think.

 

Better watch out Norman...

I know a little bit more about making HP than you think.

 

What's that el camino make for power? Probably 285 like every other SBC guy.

 

Lol, It's not my car. I am a ford guy. If he ever buys a jetting kit I think I can get about tree fitty out of it.

 

You could always do a speed test going from 0-what ever your bike tops out at with stock setup and then one with the mods. That will tell you how much faster it increases speed do to HP gain and then do the math on the difference and that should give you a % for your overall HP gain. I would say you have a higher chance at a 1-3% gain in HP rather then 2HP. Sorry but I do agree with the other guys on this matter. My 110 is bored and stroked to a 155 with a stock head for higher combustion and I know I didn't receive more then 3-4 HP if that much. My bike is not stock by any means but it is nasty. lol
Good luck and I hope you prove us all wrong.

 

Thanks Holman for the suggestion. Too many variables and opportunities for the trolls around this place to take more shots at me. As far as gains my butt dyno could not reliably detect less than a 5% gain so it has to be more and my butt say's it's a lot more, lol. A big bore will not give you any MAX HP gains if all you change is the CC's unless you combination is overkill for you current CC's. It's would change your power delivery but you would need to find a way to get more air in and out to increase HP. An increase in compression will add a bit of HP but has other side effects. It's all about finding the perfect match to get volumetric efficiency over 100%.

 

I think if you had the test mentioned by us we would be more apt to accept the claims, we dont even really accept the claims from big companies like Takegawa bc they hyper inflate their numbers. StorminNorman did alot of dyno comparisons and testing so we have got accustomed to have really well backed data. You dont NEED a dyno to justify estimated power but seat of the pants testing isnt really a valid test as its easy to be tricked by the sounds of mods to give a false sense of speed. A simple time between two points is all that is needed(for example two mail boxes), you can actually get pretty good estimates that way, Drag racers can get really close estimates this way so no reason you couldnt on a bike. Also the dyno with the mods wont mean much if you dont have the results of the stock as its all about % gain. I do actually want to know the improvement so dont take this as me trashing you, I just am picky about the data( I am an engineer after all haha)

 

What sound could I possibly get tricked by? It sounds like a stock bike.

 

The intake mod removing the snorkel in my experience creates a larger sucking noise and there is a slight increase in exhaust note from the additional air flow as I did an exhaust header drill out at the head.

 

The stock header is only about 1/2' to 13mm opening witch is pretty small. I ported my header out using a 5/8' grinding bit and drilled 3 3/8' holes in the back side of my exhaust and it made a world of difference.

 

I did not notice any sucking sound. Did you open up the hole in the airbox? The only sucking sound I hear is if the bike is lean and was like that before mods as well. Very minimally increase in exhaust note. It seems folks are still more interested in telling me I am wrong than actual results.

 

I did cut my airbox hole to match the hole in the frame cutout. I didnt say it was a massive noise but it is there. I really would like to see the results and if it was really a 2hp gain Id be very impressed, I just know from mine it was no where near that, if I had to guess maybe 1hp gain(purely speculation), it was just a better throttle response and pulled a bit longer on top which wouldnt even hardly show on a dyno.

FYI Ive probably caught more attacks than anyone on here(look up the debate on the crf150r with 14/12 wheels as its 30+ pages and half the posts basically called me an idiot)

 

I do undersrtand. They key to finding the horsepower is in the jetting. The stock jetting is marginal and doing the mods changes the requirements significantly. If you heard a sucking sound you where lean.

 

Validating parts is serious business
Not all rear wheel dynos are calibrated the same
all tests performed on the same day same fuel same starting pull temps is a good beginning.
Then add in a lambda system for help.
Usually percentage of increase from start to finish is a bit more realistic.
Most will strap down the bike and if lucky warm it up then give You a 3 pull graph.
Want to get serious about it.
Test 20 - 40- 60 - 80 and then 100% throttle for comparison of the new parts
many think they spend a majority of time at WOT.
Well strap a logger on it for a bit and be ready to be surprised in many cases.
Take a way broader power curve all day long over a small percentage of peak any day.
A 28% increase on the little engine without bustin it open would be impressive.

 

Trust me, I don't need a lecture on the idiosyncrasies of dyno testing. If the aftermarket was held to the same standard as I have been advised about they never would have sold a part. It's a free mod FFS.

I don't have to prove jackall to anybody here. Why don't all these experts show me all the horsepower they have found? TBH I am ready to take my ball and go home. I guess by trying to help a few people and share something good I am opening myself up to this internet nonsence.

 

Relax chief, It's 2020. Not 2002. These mods aren't anything new or anything that can't be easily searched on the forum or on google.

 

No lecture intended
Just a slice of how its done in this zip code
Was excited about seeing a true +2hp posted in the title
There is a great group here and a few well understand what it take to generate a simple real +2Hp
Was disappointed to find out it is just a guestimate from a rig with a soft rear suspension
A simple AIM logger will validate a true Observed not calculated experience.
The Dyno here is known as the "Heart Breaker" for a reason.
Bike sounds Good
Just a bit oversold in the title Bud that's all.

 

Thanks! Point well taken. The title did not say anything about dyno included. If I had access to a dyno it would have been included with the original post. Yes they are on the internet. That's how I found them. The problem is the stories of people didn't match the results I was getting.

 

Its way Cool to see Your Enthusiasm for improvement
Keep the wheel of wanting more Knowledge turning.
You have a Go pro its a good start for time and distance testing

Enjoy
B Safe.
