Non Genuine Rubber manifolds

Hi all
Looks like I may need to replace the 4 rubber intake manifolds for the carbies and my local mechanic says I'm looking @ about $100 each for them. does anyone know of an after market one that is cheaper yet still of decent quality?

Cheers
Sammy

 

May need to replace?
Are they leaking?
What shape are they in?

You might be able to get another season or two out of them by doing some repair work on the ones you got.

WARNING:
The Cap Screws holding those Manifolds on to the Head are made of some pretty cheap and terribly soft steel.
Don't break even ONE off!

If you try to remove them and they don't budge ... put-off the work until the Off-Season!

 

Hi Rick

I just bought the bike (and it's already turning into a nightmare ... Thought it was an '81 750 which the frame is but it's an '80 650 motor I now realise.

The rubbers look pretty bad...someone's attempted to seal them with something before....I'm not sure what but they're covered in some sort of sealant.

The bike gets up to running temp and then idles @ about 3 - 4000 rpm, so it looks like it's sucking in extra air somewhere.

 

Probe it for leaks.
Use a Propane Torch. Just turn the Gas on ... (don't light it!)
While its running ... probe all over and around the Intake Manifolds, Carbs and Boots.
Listen to the Idle.
If the Idle increases ... you got an Air Leak.
If it don't ... you need some tuning.

 

Holy cow Sam. For my 550 Seca, boots & gaskets were under $200

 

Ahhh the joy of being an Aussie....Lots of space, few people, long way from everywhere, and everything costs more :cry:

2 Left rubbers $94.10 each
2 Right $85 each
4 Gaskets $10 each

Aussie $= about 87cents US @ the moment

 

here ya go... 100 a peice is WAY to much

Thanks... A website worth Bookmarking, but Doesn't look like they have the manifolds.

I'll look up the part numbers and see what I can find out there I guess.

Thanks anyway

 

Manifold Boots-R-Chacal!

ww7) OEM and reproduction INTAKE MANIFOLDS, both original and reproduction individual manifolds and complete sets are offered to allow you to replace cracked, dry-rotted, vacuum-leaking (making carb tuning
impossible......) originals. These are the vulcanized rubber-over-aluminum tubes that run from the front of the carbs to the cylinder heads!

NOTE: the reproduction manifolds are excellent quality, basically indistinguishable from the originals. However, the gaskets that come with them are a very thin paper style, much less substantial than the originals, although they probably will work okay. You might want to consider buying some of the original manifold-to-head gaskets when ordering a reproduction kit.......

That should be enough to get you started... PM Chacal for current pricing and shipping information.

 

Ah ha...you didn't tell us that Sam!

 

Even at that exchange rate, and with shipping, Chacal can still do a lot of good for you, Sam.

 

:lol: Could be worse.... I could be a Kiwi (New Zealander if you're unsure what I'm talking about :lol: ) !!!! Things are usually even more expensive there!

 

Often look at the prices you yanks pay for bits and bikes and just shake my head,but on the bright side we dont have an off season.
Especially in Byron Bay,eh Sam.
Pretty much bike heaven for roads and weather!

 

The funny thing about living up here is that if anything, the off season is in summer 'cause it rains so much, but if you're prepared for rain properly, it's actually not so bad.....except that I have about 17 creek crossings which turn into torrents during the heavy rain (but I'd take that over cold 8O any day).....

Give me a home among the gum trees
With lots of plum trees, a sheep or two, a kangaroo.
A clothesline out the back, verandah out the front
And an oooooooold rocking chair.

:lol: & a nice bike too!!!! :lol:
