Point 4. My bike was tested at the Rear Wheel. The conversion factor is that as stated by Viper biker. Which is that my reading on the Dyno being RWHP at 48. whatever I forget already, should be roughly Multiplyed by 1.25 to give the Crank power. That means my bike is Running just over 60bhp at the crank. According to Viper biker anyway and you all roughly seem to agree with what he has to say.. this tallies in with the expected power and the Official Honda given power Figures.


Point 10. No, honest its not me. LOL


But serious. im not taking any of this personally and would probably really enjoy a day out with all of you. What bugs my shit is that people put me down a lot when Im right.

RACE RACE RACE!!


I seriously couldn't care what power my bike puts out on a dyno: she's fast and I love her!

When it comes to improving on it though, a dyno is a different matter.

Fair enough but dont you find it a bit strange that all the other graphs are rwhp and up around the 55 - 60 figure.


The main thing is that the bike is on the road and youve got transport again. Presumably its you we have to thank for the recent bad weather? Wasnt there a heatwave right up untill you got the bike sorted? :scare:

That means I got a bargain on my exhaust system, if my bike was only running at 45-48 horsepower before and now it runs 62.7, thats a 15-18bhp increase from a half system, one of the best increases ive heard (and before you say anything about engine mods, the only thing changed in my engine is the jets in the carbs. and they are only 118's)

Hi challymo , you just don’t get the point , you cannot compare two different bikes on two different dynos , who has said your bike makes 47 bhp no one has !( it may have made 55bhp on that dyno before the exhaust was fitted) then you fit the exhaust and you get 62 bhp ,so that is a increase of 7bhp not 18 bhp you are just plucking figures out of thin air , you can only compare your power increase after fitting the exhaust by having a before and after run on the same dyno ,not different bikes different dynos.,you use the dyno as a tool to see what effect the changes you make have on the engine to see what works and what doesn’t .
There seems to be a lot of desktop expert motorcycle tuners posting un educated theoretical opinions that are ok on paper but not in the real world, how many of you actually work on motorcycles or tune bikes for a living? at a guess not many, but o so many are experts .
A modern load control dyno has come a long way from the old style dynos working on Jurassic windows 1995 BC operating systems ,its called technology , I have more accurate testing equipment in my workshop than Honda had in 1989 so who’s to say that the HRC or Hondas race bikes didn’t run a bit rich to get the best power ,the answer is they didn’t know ,as the technology and the computing power just wasn’t available at the time .The AFR is a good guide but its not set in stone for getting the best out of a engine , some bikes like extra fuel to produce best power , some like a little less it all depends on the engine and how it burns the fuel mixture ,
Some of you seem to be running my company down with the way I have set up hamsters bike and you obviously have your own favourite dyno company, but the dyno doesn’t lie it’s a machine not a human , so if his bike shows a better curve and more power with bigger jets then that’s what the engine likes and it is what it is, there is no perfect set in stone AFR for producing best power ask any dyno operator ,yes a over rich mixture can affect power as can a weak mixture, but thats what its all about finding out what works best .
I have no problem with hamster having a dyno day at my company or bmc racing in Shropshire it makes no difference to me , the point of the exercise is to test the bikes on the same dyno to give each other a good reference point to how their bike is running and how it compares to other bikes on power ,you cant do this by waving a 5yr old dyno chart from different dynos about.
Same day ,same dyno . kev@projex

Hi Kev,

I think Challymo's comment was probably tongue in cheek. Its a bit unrealistic to expect that much of an increase just by fitting an aftermarket exhaust.


I dont think anyone is trying to run your company down. Possibly the way that the hamster told everyone they were wrong in their thinking has got a few peoples backs up. Some of the guys on here have had NC30's for years, theyve built them, raced them and modified them and to be fair, they do know what they are talking about. He posted some dyno results and going on what other people have seen their bikes produce, his do seem a bit low. You might notice that help was offered to see what was up with his bike, in fact, as you know, the problem that he originally came to you with turned out to be electrical rather than fueling related.

I for one would love to come along to a dyno day. Ive been meaning to get the bike sorted for a while but ive also been bitten in the past by taking my bike to a place that didnt really know what they were doing. - This was a regular bikeshop and not a dyno place but it was the first time my bike had been to a bikeshop since i bought it and i wasnt overly impressed. The mechanic i have now is fantastic and i trust both his work and his judgement on what needs doing etc. I think now im more likely to go on recommendations for getting work done or gut feeling on the people doing the work. You coming on here to defend your viewpoint says a lot and is a very big plus.

Also, it will be a good chance to meet some of the guys from the forum, ive been kicking around on here for a couple of years at least but never really put faces to names etc. Catching up somewhere where there are bikes, cups of tea etc is a good idea.


Cheers

Ian

Hi Ian
A lot of the posts that have been made have been tongue n cheek or just made in ignorance, but either way it didn’t make my company sound very good. I can only do so mutch with a stock bike, as with any bike power is down to how deep your pockets are and until you start changing things you are stuck with what you have.
I have a nc30 track bike myself and have spent a lot of time testing parts and trying things to get that extra out of her , when I first got the nc it made 55bhp (on my dyno) with a full ethos system hrc needles 135mains and no filter in it ( eek) , it now makes 61bhp with smaller mains ,std deedles and a k&n filter in it, and a lot of testing to find out what worked and what didn’t .
Yes I agree there may be a vast amount of people with a lot of knowledge about nc30s on this forum but a lot of the posts were made by spotty faced students or pen pushers with the mechanical ability of my 8yr old daughter, who probably have trouble wiping there own arse without a Haynes manual
I admit i may not be rick oliver when it comes to nc30s but I am no fool when it comes motorcycle tuning or anything bike related , no doubt you have been on my website for a nosy , you want to see some of the things I have to sort out ,it makes nc30s or any, what I would call stock bikes a walk in the park , I have a very good reputation in the biking world and I have built many magazine feature and show wining bikes over the last fifteen years , and every part has been made with my hands( apart from the obvious), and I have a lot of pride in what I do, unlike most fly by night bike shops who haven’t got a clue .
Richard saunders has used my company to set up his ZXR400 , and the last I heard he was leading the EMRA F400 championship , his bike made 73bhp last year on another dyno but the best run we had was 67bhp , so as you see there can be a big difference in dyno machines .
Hamster is one of your younger members, and he started a thread about organizing a dyno day for people on this forum, and a member of your forum showed no respect to hamster and openly posted their dissatisfaction with his choice of venue , he should have sent a PM to hamster regarding his choice or he should have started the thread himself and not blatantly ran his choice down for all to see , its called manners ! .
