Not to throw gas on the fire but i've run wiseco and venoila forged pistons,,pistondude is correct this is a squeeze casting,,,there would never be this granular look  ? There is no fire.... Am i missing something here? Pistonguy makes the disclaimer he's not trying to be confrontational and you say you don't want to add fuel to fire... This isn't an argument or even a debate. With a name like pistonguy, I'm wagering he's a piston aficionado and likely knows his stuff. If he has valuable input, it will be accepted as such. It is also why I shot off an email to Taida's tech team. By this time tomorrow, we will know what forging process they use... I'm Confident in my findings. The picture says a Thousand words, you just won't see Texture like that on a Forging. For the better part of my 55 years I've worked directly for One and several High Perf Forged Piston MFG's. There is Only One Forged Piston MFG in the USA that MFG's its Own Raw Forgings. I will also be confident the response you get from Taida will be either the responder doesn't really know so he will stick to what the label says or they are ordered to Wear the "Corporate Hat" and stick to what the label says, Either way its a nice piston, nothing wrong, just not a Forged Piece as Labeled. |

How about some dyno runs of the stock vs stroked motor showing the full torque and horse power curves with the same head and piston if possible so we get a hard numbers of what is gained from stroking the motor?

How about some dyno runs of the stock vs stroked motor showing the full torque and horse power curves with the same head and piston if possible so we get a hard numbers of what is gained from stroking the motor? That is an excellent suggestion and it's something I want to do really bad... However, I don't quite know how, nor do I have the means currently.... I thought about getting an electric motor/generator, and fit it with a scooter wheel (acting as a pulley)... I could then belt the scooter motor to the generator and measure the current output... However, electrical motors are not 100% efficient and I would lose efficacy in the pulley setup.... The reason I haven't pursued this route yet is because it doesn't seem practical because I would need different rims for 10" ~ 16" rims.... I do have a friend with a 3D printer, perhaps I can get her to make me some gears. Does anyone have a good idea how I can build a dnyo bench tester? I already have something for measuring current. This is my latest invention. It's an electronic load simulator. I can hook it up to a stator (or even a running scooter) and measure how much current the stator can produce throughout the RPM band. Here's a video, Check it out, it's pretty cool: |

No Local M/C shop with a Superflow or Dynojet Chassis Dyno?

No Local M/C shop with a Superflow or Dynojet Chassis Dyno? Not that I'm aware of. I live out in the country, about 30 minutes away Kalamazoo, 45 min for Battle Creek and about 1 hr for Grand Rapids. In short, "Local" in this case is a relative term because I would say I I don't even have a local M/C shop, let alone one with a Dyno....  Besides, don't know if you've seen any of my videos, but the amount of engines I need to have dyno'd is a lot. So, last night I figured I would research Dyno's a little better and this is what I need: SD12 SCOOTER DYNO .... It's right around $7000 and with accessories it can go up $15,000... However, they also lease. I wish I wouldn't have discovered this because now I can't stop drooling over it. It would be the ultimate tool for my shop when it comes to diagnosing issues throughout the power band. ----------------------- We have to wait until Monday for an answer about the forging. |

Gotchya. I'm a Big fan of Dyno's It does take some training/practice to make very accurate comparative testing. Many Parameters to consider. Need a Whole Dmn Weather Station. Oh, we don't have to wait till Monday, I already know |

They have a 3 day certification course I would have to attend in Las Vegas, Nevada. I got married in Vegas and go out there (I live in Michigan) every now and then. I may try and make this happen when winter comes around.... If I took their course, I'm sure it would arm me with the info I need in determining if I can build one of these. My motorcycle lift has a big cutout and it could be fabricated into one of these.... I asked my friend with the 3D printer (she also used to be on Professional drag race teams) about making me pulleys and she said she advises against it. Doesn't think the plastic is durable enough... But she recommended that I may wanna build something called a "Pony Brake"... You ever hear of one? She provided me a link to a really good article, check it when ya get the free time and tell me whacha think? |

All True Builders use these. and there aren't many. You can make your own Chain Drive Water Break Dyno with a Depac Computer system. The Mathematical Formulas are Available in Machinist Guides. A bit involved The Drum/Roller Chassis Dyno is most common in the Two Wheel World. |

Married in Vegas, Huh, Been there done that.
Went to the Chapel in Cuffs, Bad idea, the marriage ended the same way.
I Miss My X, Next Time Ill Take Better Aim.

The judge asks " why did you shoot her 32 times mr piston?",,,," because I ran out your honor ",,,  |

Absolutely amazing to see them being driven by the low RPM old time steam and gas/diesel tractors. www.google.com/search?q=prony+brake&gws_rd=ssl |

Oh, we don't have to wait till Monday, I already know Ok, this wasn't exactly the answer I was asking for, but it's what she replied with... This is the company Taida has manufacture their pistons. Watch the video then you tell me if they're true forged pistons or not: |
