again your wrong!!!!! cutting the head down involves milling material off the bottom of the head raising compression what u do if not using a spacer is cut 2mm into the head dome not take it off the gasket surface 8-|

i knew it had low compression from the "weird noise" vid you posted.. it looked way too easy to spin the flywheel.

 

[Whitty21]

i am not sure, but hey, i am a noob

 

[Whitty21]

totally terrible and out of scale btw

 

[Awk08]

i dont know if bronc's motor is straight out the box, but he was running race fuel all weekend at the "awk mt. ride"

 

[1bad442]

[scotj77]

hey you been in my garage 442! LOL!

 

[Whitty21]

haha well i had the idea right lol, thanks 442, i knew what they did, just not where they were lol that is a sexy crank btw lol

now i get it!!! lol on topic my vitos 240 was around 170 and i was running a mix of 110 and 93 octane. vitos told me around 170 you should start using a higher octane. so unless the compression test was off a bit i would say its time for some rings, however if its still running good you could just keep on riding it. i know a couple times i took my motor appart and it was running fine. kinda regreted it a little cuz then i didnt have anything to ride... i had to make sure it was gonna be able to handle me at busco.

You need to hold the throttle wide open and kick it til the guage won't move anymore. More then 8-12 kicks

Yes i held the throttle wide open, and the guage did not move after 9 kicks...

 

[79 bronco]

if it didnt pick up with oil that means your rings are sealing good

It did pick up about 7psi after oil...

so is the head cut or is it still a pump gas motor awk said u were running race gas on the mntn did u need to or just wanted to??

 

[79 bronco]

is that a pump gas motor or a race gas motor

I have to run 100 octane out of the box, a mixture of 50/50 pump gas and race gas....

 

[1bad442]

compression is def low then should be up around 170 - 180 i would think

 

[Surfrjag]

i had a blown headgasket for a while and never even knew it till i took it appart...

 

[1bad442]

and if its been making that noise for a year and a half its quite possible it was honed wrong when it was brand new i woulld check piston skirt too wall clearnce when u pull it apart

Time for a new piston and bore job... a stocker should have 115 minimum. Shes toast
