I'll ask on TR

Comments from TR:
- They'd prefer to go high compression with the coating
- They can't get 93 octane gas in Cali (only 91) so the high compression couldn't be too extreme
- There might be some interest in 49cc pistons that are high compression with the coating
- They'd like to see some results before they mod their bikes

I dont see why we'd go 49cc with higher compression, to save the $80 reboring fee  When your spending $200 on a new piston, why not spend $80 to get what is sure to be a huge increase above the stock, Seems kinda dumb  About the 93 octane, very few places actually sell it, i think mohawk is the only place here that sells it, and it is 15c a litre more, so about 60c a fillup for more performance Perhaps going for a higher compression piston suited for 91 octane would be best |

Here's a vote for at least high compression from a Metro rider. The coating...I'd want to see price and actual effect first, especially if we're talking a $50+ process. If nothing else, you can at least count me in for the project as a whole, I can help spread the word to the Metro riders happy with just a variator and some new weights  |

I pump 91. I would pump 93, but there are no gas stations in the Bay Area that have 93 avail. 93 would be sweet.

I just can not justify the cost and time on a stock bore high compression piston, and i guess everyone would be happy to stand on the side waiting for the kit to work great and then buy it, or if it does not then on to another thing, so i guess i will have to prove that is worthy, the octane problem is something i will have to talk over with the wiseco people, more than likelly we will have to make it for the biggest market which appears to be the 91 octane Any final pricing will have to wait until monday, then we will really know how much we are talking about

91 isn't that much different that 93. I think we could still increase the compression from 11.9:1 to about 13.5 still.

as long as it will give me more power  BTW Dan. Tha Cams is sitting on my desk. I firgure I'll wait till the piston is done, then i put it in. I'm waiting for my manual to arrive. |

upping the compression is cool, but isn't that kinda peaky at 13.5? And i would have thought stock compression is extremely high already

cool keep up the good work Chanito, and i agree the higher compression stock piston isnt worth your time. I dont see why your worried about the new piston not working great, a 15% increase in displacement is sure to have positive results. The only thing id be worried about is if someone else comes out with a piston before you do . And in reply to those on T.R, I would love to see the results before and after everymod before i do them, but its not possible, so just trust the great Chanito |

Jasper, I was a bit quick to speak with that 13.5:1 figure because I don't know much about compression ratios. I'll shut my mouth and let Wiseco do what they think will work the best but since we only need to run 87 octane with the stock 11.9:1 going to 12.9:1 or even a bit higher doesn't seem like it would require more than 91 octane. However, I don't know much about 'peaky'-ness and how that relates to compression.
I agree with Timber that the concern seems pretty unfounded. Regardless of the decision on compression and the coating the difference is still huge and for sure you'll be going noticably faster and the concerns that our engine will blow up or something doesn't seem founded on any reasonable grounds because 1mm of sleeve is still plenty plus the walls are still a good 5mm thick which will never be an issue and lastly the cooling system shouldn't have anyproblems. I've ran my engine in the summer without any coolant and as long as you keep it below 30mph it won't even over heat. The only reasons I can see for not getting a piston would be cost or your lack of willingness to tune in the carb for the new found power.

since im gonna spend the $200-250 on the piston, and then prolly another $200-300 on the install, i might as well pay the $80 and have them dyno tune it |

It's be nice to have the piston by April because I've got the month off so I could do a lot of testing etc. plus hopefully an install vid.

An install video would be cool!

 OK here are the news, we will have hi-compression pistons with low friction skirt coating  they will cost 220 dollars, so to clarify, it will be a kit with the piston, the rings, the wrist pin, the circlips, the head gasket and valve cover gasket, crank seals and silicone sealer. I will charge shipping, and since i do not know how big and heavy the package is going to be i can't figure out that yet. They should be ready for delivery at the beginning of April, there is only 24 unit being made as of now, but two i will use, so i will have 22 units for sale, hope i can sell them all, making more would take three weeks

rock on, and for all those worried about not high enough octane, you can buy octane boosters for your gas at Canadian Tire Chanito, whats the lowest octane we should be using for the new pistons |

count me in on one of those new pistons as soon as theyre ready |

I'm glad you're going all out and making the perfect pistons. Now there is no way anyone can come out with a better product (unless we get into 4 valve conversion which I don't see happening). The only questions I have (other then when can I pay) is why are you including a new wrist pin? Isn't that reuseable? Also, make sure you order all those gasket etc ASAP so the kit isn't waiting on those because they'll likely be backordered from your Honda dealer since you'll need so many. Thank for all your work Chanito ;D I'm stoked! Have you actually placed the official order with Wiseco? |
