Hey Chanito, just curious, ~ how much are the pistons gonna cost, and when do we expect them done by? Im just trying to wager my $$ to see how much i got to spend on my ruck for the time being, living from paycheck to paycheck with my insurance and gas covered for the year  |

I think it's gonna be a bit before we know a final price but I think Chanito has posted elsewhere that it should be under 250$ for the piston, rings and custom head gasket. I'd guess we're still looking at a 2-3mth wait so they should be here for spring when your wallet's fatter if you can stay away from the BSS.
PS - This is my 1900th post. I've really been reeling Chanito in today and the race to 2000 is getting tight. I was back over 50 posts a couple days ago.

Well, i have some good news but not as much as i hoped, the machine shop run some tests and the ruckus cylinders are not coated or chromed as it was stated ;D  , they have a sleve so yes they can be rebore easily, the bad news is i have to find another machine shop to bore something that small  so i still have not find that elusive price for the rebore, i will have to go to another one tomorrow, some interesting details the sleve total thickness is 43mm so we are at the max anyway with the 41mm piston

Rebore price is $85 CAD, i had a local shop quote me that. Try a motorcycle shop chanito  |

cool, try and get a dyno done with a before and after the piston's installed, despite how innacurate they seem, always good to have an idea of what we're getting. If not ill get my shop to do it

Yeah I've talked to a local motorcycle shop too and they said it should be under 100$ Cdn (87$ US) and they'll have no problems doing one that small.
So if I understand correctly, the diameter of the sleeve is 43mm across so a 41mm piston still leaves us with 1mm of sleeve on all sides. Is 1mm of sleeve adequate?

 In theory yes, my only fear is that it might warp if allow to overheat, and the conical shape in the bottom which allow you to install the rings easily will be gone, so we will have to compres the rings while pushing the piston in, not as easy as stock, the engine have a lot of aluminum around the sleve, so it will actually should run cooler than stock ;D

So 41mm is okay? Because if we start going much smaller then these pistons won't be worth it. A 41mm piston is a 17% increase in displacement which is significant (imagine a pickup truck going from 4.9 litres to 5.8 litres) but any less and I start to question the cost/benefit of the project.
I actually noticed how the sleeve widens at the base when I installed my new crankshaft and figured that's what it must be for.

1mm is way thicker than any coating, so we are ok on that department, but we do not have room for more, so 41 it is, i finded a place, they will quote me on monday, as i explain them that we might be doing quite a few (hopefully), i will fabricate some spring compresor so we can install the piston easily ;D

So Monday i will know how much for machining, i will send the piston and the head to find out the price and when the pistons will be, also i have to send thwe gasket to the gasket place to also find out the price and when they will be ready, hopefully will know within 2 weeks all we need to know , but hopefully the pistons will be here by April ;D

Anything to update Chanito? How many pistons are you going to make the intial run for?
You should buy a little engraving tool and lightly engrave inside the piston 'Chanito Motorsports Piston #000002'. It make them seem so special but maybe even that would set off the balance of things.

Not much to say yet, all i have been told is that the aluminum has gotten more expensive, but it is still within budget, the first run will be 24 pistons, and i will see how fast they can be sold so i will make more as needed

Aluminum has gotten more expensive??? Meaning that Wiseco is upping their piston prices at bit? It seems that the alumium costs would be such a small part of the cost compared to the R&D and tooling that even if the price doubled it'd only be a couple bucks more per piston.

So have you actually placed the order with Wiseco yet?
Also, is my local motorcycle shop gonna freak out when I walk in there with 1/2 of my case and say I want my sleeve bored out so that the walls are just 1mm thick? I'm no expert at boring things out but that doesn't seem to leave much room for error.
