One suggestion Chanito is that you should include a photocopy of the page in the service manual where it tells you how to apply the sealant.
Also, what will the compression ratio be? Surely Wiseco calculated that...

count me in on one of those new pistons as soon as theyre ready  Chanito should have a nice burst of intially sales and then a nice constant demand once the performance result are and people see my Veypor VR2 graph showing my 6 second 0-30mph runs. |

 Wiseco was suppose to sent me an email with all the important info, but i guess i will get it tomorrow, they include the wrist pin so they can use a lighter and stronger material and stand behind its product, the octane rating require will be 91 octane  I can't include copy of copyrighted material, they will sue my behind in a hearth beat, but i will include a page with some instructions and the torque specs, plus i will probably do a how-to and post it here

 I forget to mention the gaskets will be made for the engine and are not Honda parts

Sounds good ;D I do have another question....I've been all excited about the special coating on our pistons but now that I've stopped to think a bit I can't really figure out what it does. It supposedly is a low friction coating but the piston doesn't even touch the walls right? Don't just the rings touch? Please explain...

Nice work chanito.  I still would like to get my hands on a kit, not sure when I would do the overhaul though. Hopefully I'll have the cash for you by the time you get them, I need a set of tires for my truck now, almost went off the road this past weekend in a snow storm this past week end. None the less, this is great news. |

You rock ;D Did they give you a more definate date when you placed the order?
I am still wondering about what the coating does (as detailed about 4 posts up). Could you explain?

My guess is that the piston still rubs against the walls and the coating is just extra protection against wear.

I just remembered what this is called...piston slap.

The piston skirt is a little smaller than the area where the rings go, as the piston heats up this skirt will expant and will ride on a fine oil film on the cylinder wall, ideally this film thickness is just small enought to prevent the piston to be too lose and slap the wall as it goes from top to bottom and up again, if they are too loose this slap would be so strong it will make a very big tapping noise, known as piston slap, and is bad because it will wear the cylinder wall badly, and big enought to allow some oil between the piston and the cylinder wall. So yes the piston skirt rides again the cylinder wall, other wise if only the rings ride on the cyl wall, the piston will rock, not good. Anyway the coating (like teflon on a frying pan) will make the demand on the oil film less and the piston will loose less energy as friction I do not know how much power this will free up, but any little helps at this time

Thanks guys! I guess all that's left now is the waiting portion. In the mean time I'll contact my local shop to make sure they can do it and get a price estimate etc.

I hit up my local motorcycle shop today to see what they had to say about my upcoming bore job. Initially they were concerned because they thought our engine has an unsupported sleeve (which it does not) and they thought it was a 2-stroke. Once I had all the specs sorted out they said it would be fine. Here's what you guys need to tell your local good motorcycle shop:
You're interested in getting your 50cc, 4-stroke, liquid cooled engine bored out. The stock bore is 38mm and you'd like to increase that to 41mm. The cylinder fully supports the 2.5mm thick iron sleeve the entire way via a 5mm thick alumium alloy outer wall. The sleeve is 43mm wide so you'll still have 1mm of sleeve left.
If they don't understand you their main concerns will be that the sleeve is made out of some wierd nickle composite or something that is really hard bore. Also, you might need to reassure them your sleeve is supported the whole way. The sleeve is just the inside of the tube that our pistons slides up and down in but it's an iron tube that's pressed in because it resists wear better than alumium alloy which makes up the outer 3/4 of the wall. You can read more on this in the FAQ - Chanito thread. When they ask if it's supported they are wondering if the actual iron insert sticks out the bottom of the main aluminum tube or does the aluminum reinforce it the whole way. If the sleeve was unsupported and we wanted to bore it down to 1mm thick then it wouldn't work.
Anyways, so yeah once they understood what I wanted they said it would be no problem. They said if I bring just the case in then the cost would be 68$ Cdn (55$ US) and it wouldn't be hard to do or take very long.
One important thing Chanito: They said they would really like to get some clearance specs from Wiseco for the piston. Is Wiseco gonna provide that?

The piston should come with a clearance specs and hone finishing specs, that means they will recommend how tight the piston should be and what kind of grit to use to hone the cylinder wall ;D

ETA on pistons , ill probably buy it and then let it sit until ive decided what im doing ruckus wise |

I am still waiting on the engineering drawings and spec sheet, which i will post as soon as i get them, then the production department will take over and we will have an ETA then , i am running out of nail to bite, and i still have to get the gaskets done, i will do that next week

Is there any chance the valves will hit the piston if I use the H.O. cam since the piston is high compression?
