1. Is there a set formula for which carb jets to use for specific parts combinations? Like since I finally got the Two Bros carbon full system, I want to combine it with the K&N air and oil filters with Royal Purple oil, and maybe the airbox/snorkel modification recommended by the DynoJet kit. Which jets should be used?
2. Exhaust wrapping or ceramic coating. Is it worth it on the 250, especially on an the 2Bros full system? Does it make the bike at least feel like its running cooler when the summer temperatures finally get here to Texas? |

Dyno tests have proven that oils like Royal Purple have less friction, and free up some horsepower, not much, but even 1HP is a noticeable gain on a small bike like this.
That means the carb and jet settings (or EFI mapping on injected bikes) COULD need to be changed to accommodate the higher horsepower potential. |

Royal purple is a waste of money and will not make any difference at all for power unless you switched from something like ... vegetable oil or something 100k miles old.
covering your headers will make the bike run hotter.

you may see gains in HP on an 8 cylinder high displacement engine, but a 2 cylinder 250, no.

Some oils, like Motul 300V, can give a power-gain up to 3% (even on a 2-cylinder).
But also please keep in mind, that Motul 300V is a real racing-oil though it's declared as street legal. |

OK, I have to admit that my numer of 3%, taken from the talk in german forums may have been a little bit to hopeful, so take this from the Motul-Webiste: ...300V Factory Line Road Racing gives a power increase of 1.30%...
Link: https://www.motul.com/de/en/about/30...tion-lubricant By the way there are many sites in the www where one could find things like this by himself/herself (if one wants). |

So what should we think about dyno runs showed from companies here in the forum i.e. about exhaust systems? Would you say when they need to sell them then we should also not trust in their results? Lucky one for sure can trust in any such information given from a German company ![]() |

But also the laws and regulations are so clear that the rules for everything are strictly given and enforced. Also please don't forget i.e. about the TUV - which worldwide stands for the best test organisation, just remember the DIN EN ISO 9000 Quality Management System. Make a selftest and ask you which high-tech cars nearly everyone in the world would like to have (besides the Italians and not the Japanese) or where the worldwide best high-tech machines are produced... And now please let's stop this off-topic talk before it could become political and not break this thread more than we already did - @Kurgan excuse me please for the off-topic. |

Since the ultimate fate of the bike is a track day toy a year or two down the road, every ounce of power is needed.
Also just to clarify, I already know all of you that say "RP oil doesn't work" are wrong. I've been running the stuff for 5 years already and I was able to feel the difference the minute I finished the oil change from the oil that was in it from the dealership with the stock oil filter which was then changed out to RP 10W40 and the K&N oil filter. Those were the ONLY changes that day because I went out for a short ride to warm up the stock oil before the change, then went right back out after it was changed and could definitely feel the difference. The bike had more power, the oil really does work as advertised. |

also, 335 torque vs 352 torque? yeah. i'm SURE the oil did that. had NOTHING to do with the way they set up the dyno, or any other mods to the car.

After here so much high qualified answers were given, I want to ask those whose high expertise knowledge apparently must be larger than that of the engineers in the concerned companies, why don't you start a production and give us the honor with the best product forever?
I for sure would buy it ![]() |

The old oil only had 1000 miles on it, the vast majority of which were babied slow miles during break-in.
To the person who said "placebo", nope. Now, end the oil garbage, I know the stuff works, and it's obvious that none of you have the guts to try the stuff because you'd rather believe the naysayers than anyone who claims positive results. You're so deathly afraid of "being marketed to" that you already form a negative opinion about something regardless of what you hear otherwise. Now back to my question......K&N Air filter, Two Brothers M2 Carbon Black Series full pipe, DynoJet kit, possible snorkel and airbox mods. Which jets to use??? |

I already bought the DynoJet Stage 2 kit, it comes with multiple jets of different sizes, and doesn't tell you specifically which ones to use.
I was hoping that someone would have already tried this parts combination before and could give some actual help on the subject.... |

i used the biggest jet, and put the washers in the middle of the pins. I have a K/N pod filter and muzzy slip on exhaust. Ran it on the dyno and it was pretty smooth topped at 27hp @ about 3500 ft. Elevation
