EU/AU PAIR Valve / Solenoid Removal

[unclesam]

yes, whiteout vacuum to the petcock it will only work in "prime".

I'm not too sure about these dimensions.

I had to file away at those holes inwards about 2-3mm on either side.

Anyhow I took the pictures of what I took out.

To remove the valve from the top end, you need to remove the left scoop, loosen the radiator and remove the fan. 5mm Allen will remove the bolts.

See my old PAIR metal tube rusted to crap, on later examination I noticed it had rusted some holes out of it.

Then I suggest you have your blocking off plate near to hand to check whether the damn thing will fit. this is the 2nd time I've had to strip the bike down to do this job because this wasn't the right size. That top drawing is what I made, and didn't fit.

Blocking off plate in place.

Here's all the crud that you're left with after removing the valve.

I am using the vacuum hose to create suction for the Scottoiler so I changed the T valve to a nozzle and just feed off of the carb like that.

I have not yet removed the solenoid since I do not have a tap/die set yet. Will remove as soon as I get them.

You really don't need a tap&die set to remove the carb solenoid.

I started this late last night, finish it tonight. - Using blank off grommets to do the plugging up. ?

[crawler]

Little confused. What's a blank off gromit. Like a rubber plug?

[nhb006]

Yep... worked fine... easy as/

[crawler]

I'll see what I can find. Did you glue it in?

[brad-drz]

removed pair valve yesterday...

but now bike pops more on decelleration :S more like crackles to be honest

is this right? or is there something ive missed?

thanks

[Harvey600]

Did you make sure the plate sealed the air port?

[brad-drz]

the air port as in where the blanking plate goes?

i put high temp sealant around it, might need to be taken off and abit more applied?

[Harvey600]

Yep, that's the beasty. If it's not sealing properly it will draw air in and pop worse than it did with the Pair valve.

[brad-drz]

thanks for quick responses, its all sorted now, the carb tube that i blocked off had small hole through middle of sealant.

[Harvey600]

Excellent, glad you got it sorted.

I was thinking of removing the solenoid next week. I'm thinking about going about it this way:

1. remove the solenoid (duh)

2. cut off the hose going to the top carb and block the hose off with either some sealant, screw or whatever.

3. The hose that goes from the air-box to the solenoid, in which end should this be blocked? I am very confused.. Is it the carb that should be blocked? or is it the air-box that shouldn't be allowed to get air through the hose?

[Mototalla]

If I just disconnect the wire going to the solenoid under the carb, will the solenoid stop working? I was just curious cause I wanted to try how it runs without the solenoid, without actually removing the whole system.

[brad-drz]

just remove it i done it yesterday, block the hole off going into the airbox

[Faltpihl]

I've got it sorted now, tried the bike a minute in the rain, I heard one or two big bangs on deceleration, but I'll have to give it a decent run to see if I notice any difference..

[sendadrd]

i went to remove the pair valve from my drz after printing off all the info but come to a problem. the tube that goes to the carb splits into two and one goes to the carb and the other goes to the petrol tap. my mate removed his the other day and his isnt vacum fed and has an off instead. if i take the tube off of the petrol tap will it still work or is there another way to remove the pair value's and keep the tube conected.
