Anyone know what type of head I have??

[dirkdiggler]

Im not sure which type of head I have on my 94 FX-1?? Its not stock(I dont think)

 

[wetjet701]

It's an aftermarket yamaha think non removable domed head cant remember if they had removable or not
says yamaha right on it

 

[wetjet701]

wow you really did splice your plug wire I thought that was a joke

 

[dirkdiggler]

Pictures old!! Those were the old $15 crappy Napa ones. I drove it with those crap wires for the last two months of summer without a problem.

Thats why I dont understand why everyone is anti "cut wires back". These new Moroso Blue max wires I just got should work even better. At least they better for $95 wires!!

The head says Yamaha on it but I didnt think Yamaha world make higher compression head? Thought thats for aftermarket companies to do? Anyone know What my compression should be with this head??

 

[wetjet701]

On the head where the plugs go in are there any numbers stamped there like 33, 35, or 37 and if you payed $95 for wires I would of just bought this

Westcoast?

 

[dirkdiggler]

ok ok ....I didnt pay $95 for them but the guy I bought them off of did!!

I got them on ebay for $30. Came as a set of 8 wires because their made for Marine V8 engines!!

 

[HBCwatercraft]

never mind,didnt look at the pic close..not westcoast

 

[wetjet701]

Thought it was a factory A/F head

 

[dirkdiggler]

MWVEW2HD is stamped in the head

 

[Mouthfulloflake]

Ive patched plug wires like that, and they worked for YEARS, in fact, one of my kawi sitdowns still has a plug wire like that, and it has worked fine for a LONG time.

it looks like azz, but its cheap ( I used a discarded toyota plug wire...FREE), and works.

you cant tell when the hood is on.

 

[wetjet701]

I think it might have removable domes, Your either going to have to remove the head, and see the stamping on the domes, or check the compression with a guage. Still should of bought a new coil see if somody on here has a used one for sale. Try oxnard

 

[Big Kahuna]

that head was build by westcoast for yamaha

 

[dirkdiggler]

So....what should my compression be at with this Head?? I assume it should be higher that stock??

I am going with connecting wires myself, like MOUTHFULLOFLAKE said, he did it and they held up for years!!

I will take pictures of how I do it and post them. Trust me, I am going to connect the Shizzznit outa them!!

 

[wetjet701]

The compssion depends on what size domes you have and if there is any porting done to the motor

 

[dirkdiggler]

I have no idea if its ported or dome size. All I know is that I am getting 125 psi compression in both cylinders with a crappy gauge!!

 

[wetjet701]

oh are you paying these women to pose with you because of the gay post the guys did to you? :joke:

 

[wetjet701]

125 is way to low does the ski run good I know it will run but for rec ridding you want 170-185. I don't know a dome that compression goes that low might have a bad guage or rings

I don't see why you couldn't with some dielectric grease on the connection with shrink wrap around it.
