forced rebuild... my rebuild ....

[El Mamito USMC]

As the tittle says, I just came back from San felipe, and my wifes cousin locked the engine(no idea how, to be honest).

 

So its rebuild time for my May race in Rocky Point.

 

So questions:

 

What piston to get and compresion? I want to keep it pump fuel.. 91oct

 

What conecting rod to get?

 

What cylinder to get? If there more than one brand.... and stock bore btw

 

And I got everything else covered...

 

 

Thanks guys

Piston - Just get a CP pump gas.

Rod - stock is fine for what you want, get a carillo if you want to upgrade, but you'd be just as well buying a new OEM crank.

Cylinder - OEM

 

Have you torn it down to see what's locked up yet? I'd do that first before you start buying stuff..

yeah i was thinking about CP but i was also looking for other real sugestions..

 

rods.. thanks for that input..

 

and cylinder, defenetly OEM..

[bvet4dog]

Well keep everything oem and get cp 12:5:1 piston from kbmotorsport for 180.....

 

That's where i'll be getting that cp piston unless there's one (new) with lower price tag.

jajajjaa just checking.. you never know if any one can get you a bad a$$ deal on parts.. but todd has always given me some good prices..

 

im thinking about getting an 12:5:1 CP and a HOt Rods full crank assembly http://www.immortalatv.com/index.php?l=product_detail&p=117

[El Mamito USMC]

Well the pistons is shot. The cylinder as well and apparently the crank is locked..

 

So I guess its time to fully rebuild ...

 

So new OeM crank assembly and berings, cylinder

 

JE piston

 

And PRO X full clucth and CFR 500 springs....

ok update on the brakedown..

 

 

 

appartently i created the problem. since i got the oil cooler and its not measured in the lil window i always over flowed the oil compartment..

 

 

 

apparently i did it so much that it created some heat spots on the engine, and since we did hit it super hard this past week in San Felipe, it didnt hold all the beating we did...

 

 

 

but hey leason learned.. and it shouldnt happen again... ill post pics later of the crank once its out..

I'm confused. :gr_confused: Too much oil in crankcase would increase pressure, resulting in seals to fail. Did you run it low on oil?

and i talked to the Team Alba guys and they said just use 1 full qt in every oil change and thats it for the oil amount... so atleast im happy with resolving one issue...

[bvet4dog]

hmm i'll have to see where 1 qt of rotella oil sits in the sight glass. Thanks for sharing that info

that wont work on your unless you have an Alba oil cooler.. http://www.teamalbaracing.com/product.php?productid=2652&cat=194&page=1 which was my problem for the fact that i didnt knew how much oil i need to properly fill it and remove air boubles. but apparently i put to much oil and creating some air spots in the engine..

[bvet4dog]

ohhhh i see. That cooler looks sweet!

[nico]

I've been running a CP 12.5 piston for a couple months and couldn't be any happier with it... But my cylinder and crank were in good shape.

 

If I was forced to rebuild, I'd be shooting for 510+ cc's at least. That was my original goal when I had the head built, so it's a bit overkill for my current 450cc cruiser.

its finally here...

oh my that looks even sexier on my big screen!

[450R]

not sure yet. we havent broken the engine yet. but ill post it once we start on it..

[450R]

Yeah but the top end is off... You should be able to see if the bearing on the big end of the rod went out... You're lucky it's only gonna cost you a cylinder/piston/crank.... It could have been so much worse.

thats about half of the engine, jajaja

[450R]

My buddy's rod bearing went out and the only thing left that was good was the tranny, cam and clutch... Believe me... What happened to you could have been much worse.
