CP pistons custom order for 350x

[The Goat]

This is just to build some awareness. I have spoken with a gentleman in there sales tech department concerning doing a custom run of pistons for the 350x.

If you aren't aware of who CP Pistons is...I suggest going to the following website

http://www.cppistons.com/

reading

and then search the web for opinions and reviews of their products.

I would say that they EASILY make the best piston in the business for an atv. They have even managed to make the 450 pistons reliable. There are many stories to be found of people toasting the top ends and finding their piston unscathed.



A wiseco 10.25:1 piston for the 350x is by no means the best piston. It is a compromise...it's what is available.


I'm proposing that we do a run of pistons in 11:1. The pistons should run perfectly fine on pump gas. Correct me if I'm wrong, but the higher compression should produce slightly more torque, and the new technology being used to create these lighter stronger pistons will also free up some more weight.

Now the big question that will kick off or kill this...is anyone interested?

He says we need a custom run of at least 4 pistons, I'm trying to convince him that these bikes are still out there in great numbers AND as of right now, wiseco is the only choice...a poor choice.

If I can make it seem economically viable, there is a chance they would carry these pistons BEYOND the custom order.

Please reply with any thoughts or interest.

i wouldnt call wiseco a poor choice.....they worked well for me for over 20 years.

how is there forged pistons better then a forged wiseco?

[The Goat]

just that a dumb goat like myself can see...

weight savings

the bridges on the bottom of the pistons look to be a lot more thought out to me... just looking at it and thinking about how the stress is being applied, I would think their curves and arcs would create a substantially stonger piston than the wiseco and oem ones. Granted this is just my thoughts on it... But I do have an eye for seeing weak points and making things stronger.

reputation... they have earned it from what I've seen.

come on now swigin, you're telling me if you didn't have that monster motor, you wouldn't be the least bit curious?

11:1 piston designed around a midrange cam... not a little curious? not curious what a piston lightened on a five axis will run like?

Im tearing mine apart as we speak What kinda price can you get? Do their pistons come with rings, pin, and clips?

[The Goat]

165.75 per piston with all hardware...minimum order of 4. That's dealer cost if you check the price of a regular off the shelf affair.

Now...we also have the option of deciding additional features.

additional gas ports, skirt coating, additional 3d milling of the interior, a CP oil groove, and a couple of other hardware upgrades.

Unfortunately, I'm over my head.

I know that the skirt coating with certain materials can GREATLY extend cylinder life as well as further increase revving speed by even less friction.

I need someone a lot smarter to come in and comment on the gas ports.

Total cost right now is 663.00 before shipping for four pistons.

additional sets of rings and other things can be purchased later on for a rebuild.

We need to committ to a bore size.

I personally...wish I could have standard, as my cylinder is new. However, I understand that others will require a larger bore...and will bore my cylinder accordingly. Unless of course I can get them to make these fairly standard. then we may be able to get multiple bores.

Still have to iron out the details.

[The Goat]

Still talking to them...goign to discuss all bore sizees tomorrow...will that possibly raise interest?

[DeePa]

people on here love to say they will take it then back out...look at the 250r carbon fiber rear fenders...no one has any money to spend here, thats why most are riding old 3 wheelers...

and goat, werent you just talking about how broke you are? How are you gonna drop 150+ on a piston if you dont have any cash? People wonder why they get into debt up to their eyeballs...its like restoring a trike while you have thousands in credit card debt...

[Erics350x]

Thats abit more than im willing to spend on piston i haven't ran before.

[oscarmayer]

you may be better off doing weiscos

if you contact www.theoldone.com and talk to larry (endyn is the shop) they are a weisco WD and have a direct link to weisco. it may only cost you 4 pistons in stead of 8 or 10.

[The Goat]

Deepa my definition of broke is having no liquidatable assets, ie cash in a checking account.

The contents of my savings and checking are immaterial. Even if they are empty, you can always get more by working.

Money means nill to me.

I was "broke" because I had exceeded my budget the pay period because of my car. My car is npw fixed, Another pay period has arrived, and I have an additional 300 bucks to spend on parts out of this check.

As for spending 160 on a piston, I merely look at how much money is wasted each month buying a bottled water or eating out or fast food... Most people spend 160 dollars and don't even realise it.

As it is now I'm questioning buying all four pistons if no one is up for the purchase.

Oscar, wiseco already makes a piston, but just like riding a trike, I want something different. And better.

Whatever, if I've got the only one in the world running a cp piston, so be it.

Parts availability WILL dry up. One would think opening new avenues of purchase would be a priority.

[Dirtcrasher]

I don't want to spend the cash right now, but I am interested.

Not sure if anyone remembers, but I wanted an 11:1 for the 200X motor but it was too much of a hassle....

Wiseco's cost me 120$ all day long so I'd be willing to pay another 50$ for 11:1 compression and I could care less who makes it as long as it's a well engineered and constructed piston.

[oscarmayer]

weisco vs. cp is a completely different debate. I've had expirneces in both. but that's for a different thread. ;)

Steve, or anyone else knowledgable, interested in helping me pick some features on this one? Even if you don't purchase one right now. If I end up having to buy all four...there will be some hanging around in my spare bedroom.

I have an NOS piston I'm going to send them as a model.

Oscar, I've found only one instance in the import world with shattered CP pistons, and it was certainly the engine builder's fault. All four pistons broke in the same spot because he didn't check his clearances.

I'd be interested in your opinion of them. I've been reading that because of their material they run a little sloppy on start up, so a warm up is required.

[Erics350x]

I'd be more willing if money wasn't so tight right now. If you do get em, i'd buy one from you later in the year. It would have to be a over-sized bore for me. I have a few cylinders that are on standard, but they all have rust and will need bored out
