Reggy ruck12/19/2023 I don't say that a dyno isn't a good tool to tune your engine, because you can perfectly see what progress you are making, just have to keep in mind that dyno results and real world results aren't the same.įor your reference, we are thinking about it at this moment to buy a eddy current braked dyno so that we can test on the street, see what result we have, and can continue with that to brake the eddy current dyno until we have the same result as we had on the street.Ĭoncerning the broken connecting rod from that Japanese company, once I drilled two holes from 3mm on top of the rod, I never broke it again, even if I revved the s**t out of that engine!. There's only 1 way to fiend out and to give a honest answer to that question, and that's taking your bike and hit the streets with it to see what result you get, and as extra bonus you see what problems you meet while testing and should be improved. if I install this or this set on my bike. We know from experience that the stock crankshaft is the weak link, so we have to fix this problem first, and then we can play ball!.Ĭlick to expand.Are you talking now about a inertia dyno, a eddy current braked dyno, a water braked dyno, a fan braked dyno, a hydraulic braked dyno, a magnetic powder braked dyno, a hysteresis braked dyno, or something else?.Īnd if you are talking about a inertia dyno, are you talking then about one with a 550lb drum, a 770lb drum, a 1300lb drum, or do you believe they all will show you the same result?.įor me it's important to be able to answer one very simple question from you as a customer: "how fast will I go?". If we did, then this wouldn't be ethical, so that's why we haven't started to produce the 180cc set at this moment. If we know in advance that you have no chance, we shouldn't send you on the field. Our job as engine tuners, and as producers of high performance parts is to analyse and to fiend out why and when a part is breaking to make it able for you to go play a game against the Boston Red Sox and to come out of it without injuries. If you keep below the 10.000RPM, you play a local baseball game, if you go over the 10.000RPM you'r playing against the Boston Red Sox where you have to come with something more as "average". The extra money you are paying for high performance parts compared to OEM parts, is, or should be because more research, testings are done and parts have been improved based on it so that can you can play at a higher level.Ĭompare it with a local baseball game, or a game against the Boston Red Sox. Our Tune-Up ECU Corrector isn't a pod controller like Takegawa, so if you don't feel comfortable with revving higher as 9.900RPM, good, then your dealer can limit it for you with our software at 9.900RPM. Your official Yuminashi dealer have our companies software and can cut and limit the ignition and injection to where you want to have it. If you are not a racer, then we aren't holding you to ask your official Yuminashi dealer to limit the RPM's where you want to have them limited. Our job or company mission is to make reliable high performance/racing parts, not to make parts for a ride to church at sunday.

I'm guessing they have also had some problems otherwise they would have these kits ready to ship and wouldn't have cancelled a bunch of orders. Who knows, the Takegawa and Kitaco kits really have not been tested and proved yet either. This will give people a chance to really put some miles on these kits and see how they turn out. I say let's see what happens this summer. People will think what they want and that's fine. The 150cc kits are working fine now as far as what I've heard. It was just a hard lesson that quality control needs to really be checked at all levels of the manufacturing process. When Yuminashi got the parts from the machinist a few of the kits had longer piston skirts than what they had specified and unfortunately made it to a few customers (me). They then sent the specifications out to the machine shop for mass production.
