whats the price?

if youre looking at OEM.. you cant beat this seller, even after shipping + exchange rates, it was still 3/4 of the price of what the local honda stealership wanted: http://myworld.ebay.com/hondaeasttoledo/

I just bought a cylinder, piston setup, gaskets, and 2 other small things, the total was 375$!! local honda shop wanted 380$ for JUST the cylinder, 150$ for piston, 50$ per gasket, their total quote was approx 600$ and I got the same stuff online for 350$

I have an Athena big bore kit that has about 4-5 hours on it.

It fits 08 and below and has sat on my shelf for close to yaer and a half. Made the big bore bike for Lorettas in 08. Took it off after the race and placed it on the shelf. Shortly afterwards I got my 09 and never looked back. It has the cylinder, piston, rings, and 06 head that is ported (no valves). The 06 head had 1 mm larger intake valves for more flow on the big bore. Lots more bottom and mid range but signs off sooner in the higher RPM's. Anyone interested? email me at jmcgeemd@hotmail.com or call me at 610-820-9292

I found the cylinder works kit on ebay for 410.

does that include gaskets and piston and shipping? if so, thats a pretty good price.

but keep in mind a bigger piston/bore will add way more stress to everything else in the engine (crank, engine bearings, tranny gears, etc..)

not trying to discourage you from the big bore kit, but you are basically sacrificing engine life for power.. which do you want more?

you can either have a normal engine that will last a long time.

or a super powerful engine that wont last quite as long...

thanks, I went with a wisco piston/stock cylinder setup. I was told the bigbore kits are hard on base gaskets... oh and yes I got everything for around 400. about the same as the bigbore kit.

I dont know about the base gaskets.. but def hard on a crank, tranny, and clutch like I mentioned earlier, not to mention rear tires!

I think you made a good choice and wont regret it. for the most part, 488CC is just too much for most people in the trails or on the trask, its only good if youre drag racing, street riding, or sand duning it.

I don't know exactly how this pertains to a Cyl.works kit but,I had a Atherna 488 kit,the parts were quality and with the exception of the copper head washers "don't use them" everything went together well,positives are big power and slows down the rev some,most of the increased power in concentrated in the midrange it really shined on uphill runs.negatives are much harder starting more difficult to jet and the pistons would crack across the dome from side to side, in the end I went back to stock bore with stock piston and near stock jetting and I like the easy starting and longer power.
