high Comp head instal

[bmxnick7]

ok i put a ada head on my ski it has 35cc domes, has 170psi each cylinder, i put race gas in it just for ha ha s, and it runs like it will idle but no wot, it ran fine on pump gas before this why is this, and what should i do with the heat sensor

 

[DAG]

what plugs are you using, it may be from using the original HS plugs,, you need ES plugs with the extended ADA head. Rip out that heat sensor ASAP!

 

[bmxnick7]

i have br8es in it,

pull the E-box, unplug the two wires from the heat sensor and remove it altogether. then use some silicon to fill the hole the heat sensor wire went through.

Also, you should be getting 185 psi with 35cc domes in the ADA head.

My heat sensor is just zip tied near the e-box out of the way right now. (I have an ADA head too.) Is is a bad idea to leave it hooked up like this?

Why disconnect the temp sensor

 

[SurferSmurf]

is there porting on the motor? race porting will give lower compresion numbers.

nah, it's doesn't matter... i had mine like that for a while before I removed it.

one less thing to flop around in the hull.

 

[bmxnick7]

im probally just going to disconnect it when i put my 701 cdi in it

 

[McDog]

You don't need race gas with that compression. Maybe that's the problem?

I'll disconnect mine and use that grommet for the remote switch on my Advent Ignition when it arrives next week.

I can't remember what the wires are like inside the e-box but do I just leave them disconnected or do they have to be hooked together?

 

[orangefinger]

why race gas ...?? I run mine with 91 pump gas...with no problems ??

the final PSI will be depending on how accurate your gauge is and your altitude your bore.......

 

[bmxnick7]

to be honest idk i just wanted to run it, i am going to put 91 in it and see what happens, my carb is still jetted for a stock 701, what does everyone else run, i have a protec pipe, op filter, and the head

they can just be disconnected...

I run 93 octane with 195 psi no problem... I don't do a lot of WOT runs. There's no need for anything more than 93 octane with the compression you are running.

protec head question

I have a protec head that has 37cc domes and it only runs 160lbs of compression, the site says it should be making 180. The cylinder is brand new ( resleeved ) with no port work, just wondering if anyone could tell me if this is common with these heads?

 

[Frosty]

not sure with Pro-tec, but all of the ADA heads/domes i've ever used their compression numbers have been dead on for me.

 

[McDog]

It's probably an inaccurate pressure gauge.

protec head question

I will try a different gage, the only thing I have checked it against is a stock 650sx, which showed 150. thanks for the info
