My computer had been acting up and i was without INTERNET for about 2 weeks, i could get into the net at work, but only for a little bit as they use it for INTERNET sales here at the car dealership where i work, last week i was in the INTERNET for a while as the work computer was not being used, while surfing i got into the Battlescooter Web page and reading thru it they said they are the only ones with a REAL BIG BORE, so when i had the chance i went to totalruckus where DaBinChe had a post about their big bore project and posted about this, and when he reply he said, the WISECO big bore was not a real one just an oversize piston, i got mad but i let it go. Then during the middle of the week i got a call from somebody wanting to buy a piston, when i called him back, he started asking all kind of questions, and after a while i came to realize that this guy though that the WISECO piston was from another scooter/motorcycle and was trying to get me to tell him from which one so he could save himself some money but buying that instead, so after the million time i told him they were design for the ruckus, he got upset and told me that it was not, as he knew that Battlescooter is the best shop for the ruckus and if they do not sell it and if they say there is no such a thing, then there is not such a thing, after that, i told him that they do not sell mine or even talk about it because, they are making their own kit, which will come on the market someday, which a guess infuriated him more, so he call me a lier and hang up on me. I just hold the receiver for about 5 minutes figuring out what just happened. After that i got so mad i went into TR and posted a thread about it, and somehow it calmed me down, most of the people there gave me their support and understanding and that make this experience a lot less bitter, i still think Battlescooter should not say that, as it is misleading, but hey that is something i can not change, and part of having a business is dealing with this kind of moments, just thought i should let you guys know what happened

I could have sworn a piston that was bored bigger than the stocker was a big bore piston. But what do I know? Don't let the stupids bring you down. It's their loss.

You are the big bore Godfather Chanito...don't let those ignorant people get to you. Whether or not they admit it, eventually they are going to figure out that your big bore is the real deal and they'll be eating humble pie...even if it's just by themselves.

Chanito,
no need to worrow, your Big Bore batches are elite. That's wahts make s it so awesome to own one............never mind waht these yo- yo's are saying, your credability, and knowledge is invaluable, so keep rocking your thing and chanito motor sports,
Chanito, Dandy Dan and some of these other cats, have a solid fix on these Ruckus' you guys know them better than most bike mechanics..........anyway s you guys know your stuff and you guys rock.............can't wait for summer riding..........yariba

chanito, is the front half of the engine the same for all years? as in, would it make sense to get an old, worn engine from an old ruckus, take the front half off, bore it, and then put it on my engine, leaving everything else as it is?

Yes it's the same.

The main part of the engine is the same, the only difference i noticed is that in 06 and later they did not install the vacuum port for the PAIR valve in the intake track on the head So yes you could buy an earlier engine and just bore the cylinder to install all your parts on it

I bought Sanjuro's 05 motor and thats what I used to put the big bore in my 06 with. I just plugged/sealed the port that is in the intake that Chanito is talking about.

i have only bought the upper half of the crankcase, it it affected as well? or is just the head that's different? the crankcase i bought was from an old engine ('03?), no damage to the body but the sleeve was all rusted out, so if a guy with a normal engine would've bought it, even after rehoning or reboring it, he probably wouldn't be able to use the stock piston. by the way, did anyone ever made a full how-to on installing the big bore? as in, besides what's in the manual. like, how hard was it to adjust the rings? did they just fit by default? or did you have to grind them down? how did you compress them? i think we need (or, maybe just i need) a very detailed how-to on things not covered in manual and "sanjuro engine overhaul" thread.

ok, i have been reading this thread and more questions come up: 1. since the shape of our cylinders is somewhat conical, does boring change it? do shops have to know it's conical? 2. from someone's experience, how practical is it to buy a high-output cam? did anyone actually make HO cams besides BSS? 3. i suggest to do a Big Bore sticky somewhere with answers to all this questions, for people who will do all the job but boring themselves. ( i know about the faq thread, but there isn't too much on big bore )

ok, i have been reading this thread and more questions come up: 1. since the shape of our cylinders is somewhat conical, does boring change it? do shops have to know it's conical? THE BORE IS NOT CONNICAL, THE BOTTOM PART OF IT IS IN ORDER FOR THE RINGS TO BE COMPRESED AT INSTALL TIME. SADLY BORING WILL REMOVE THIS INSTALL AIDE, SO WE HAVE TO COMPRESS THE RINGS THE HARD WAY 2. from someone's experience, how practical is it to buy a high-output cam? did anyone actually make HO cams besides BSS? THERE WAS ANOTHER PROVIDER OF CAMSHAFTS, BUT SO FAR THE WEB CAM THAT BSS SELS IS THE BEST, IF GIVE THE ENGINE A MUCH NICER TOP END BREATHING, IT HELP WHEN YOU INSTALL A CDI TO REV HI EASIER 3. i suggest to do a Big Bore sticky somewhere with answers to all this questions, for people who will do all the job but boring themselves. ( i know about the faq thread, but there isn't too much on big bore ) YOU ARE RIGHT, NEXT ENGINE OVERHAUL I WILL DO A HOW TO ON ENGINE OVERHAUL AND BIG BORE BUILDING

chanito, i am planning on doing my big bore in april-may, so i hope your next engine overhaul is by that time.
by the way, what do you charge for an engine overhaul? i remember talking to you on this subject, but that was sometimes last summer, so i forget.
about the rings - i read in this thread earlier that the shop that does the boring can put the piston in with rings compressed for about $5. is that still true, after a couple of years?

Regarding the rings, the stock cylinder is flared out at the bottom to make it easy to slide the rings in (as you've probably seen). When you overbore the piston this flare is gone so you need to compress the rings to get them in but it's not that hard. You can do it by hand if you're patient but it's a bit awkward because of the tight working conditions. What I do is I take a large hose clamp, oil it up well and then I clamp it around the rings to compress them. I tighten it enough to compress the rings but not so tight that it's grabbing the piston very hard. Then I just slide the piston down into the cylinder in one smooth motion and the piston and rings slides out of the hose clamp and down into the cylinder. Sometimes it takes a few tries but it's not that bad. This probably isn't the best method but it seems to work fine and it's something anyone can do themselves.
Regarding the H.O. cam....it doesn't do as much as the big bore does but if you already have the big bore then it adds a little more which is always nice. It's also a nice thing to toss all these parts in at once and then rejet once. The downside of doing that is that you don't know what performance gains where caused by each part but it is simpler.

man, finally, i read through the whole thread. that was a very long and emotional story, a lot of nerve cells killed, a lot of money invested (but hopefully all returned), a lot of hopes created but at least a big part of them realized. seriously, this big bore kit is more than just a big bore kit. it's a story. story of life. and it's good that it has a happy ending

Wow! That is some really cool info! Thanks for posting Thank you, anytime. Also, those big bore pistons, I'd smooth the rough edges to prevent hot spots and to possible improve flow. Here is an example of a 13.5:1 piston for a TRX450ER If that did not work - Sometimes I smooth them and polish them, pro's and con's to both. "From the box" Into the engine:
