are the o rings that seal the intake to the head special? in other words do they have specific "crush properties" for lack of better terms or some special properties that require the specif use of the o rings yamaha supplies, i have bought a set of o rings that fit in the grove perfectly...

Hey guys , I believe I need to change the 4 carb intake boots on my '88, they're still original, while I can't seem to find any vacuum leaks on them with the spray test , the bike seems to act like it has a small one, I have noticed some seapage around them , particularly near the carb bases. My...

While breaking down my bike in preparation of the arrival of Sean's shim kit I noticed some carbon buildup on the back side of my intake valves. What would be the cause of this (running rich) and the solution to clean them up without complete tear down? thanks in advance, Bill

Have a 98, it sit outside for years. The rubber joints connecting the carbs to the intake look pretty bad, ie, cracked rubber. Have not taken off carbs and done inspection but from what I can see, they are pretty bad, especially around the band clamps. Some of you experienced hands know what I...

Hi all I need to make some intake manifolds flanges (the face that sits against the engine head with the o-ring) and i was wondering if anyone has them in CAD or at least a sketch with the dimensions. I wouldn't like to disassemble my carbs just to measure that up. If anyone can help me i'd...

Ok guys who may have the best price on new carb and vboost intake boots? Tried ron ayres, but i think theyre a bit pricey

Have you guys seen this? Looks nice!... $$$$$$$$$$$$$ http://cgi.ebay.com/ebaymotors/Yamaha-V-Max-1200-V-Stax-Carburettor-Covers-set-4-/120762954287?pt=UK_Motorcycle_Parts&hash=item1c1e08722f And...

I ended up getting in touch with a guy in Michigan about some parts and turn out he has some 2bbl intake setups that he wants to sell. I have no interest in one but figured I'd at least post up the info he gave me. His words: Attached are 2 photos of the V-Max induction system. A stock...

Had to take the intake manifold off to replace the rubber boots that connect them. As some of you may know there is two different bolt sizes that attach the manifolds to the engine. Well, pretty sure the guy that owned the bike before me botched the bolt placement. (only had one short bolt out...

Hi guys. Just wonder if someone can tell me what the black tar crystals are in the intake manifold. Is this cause for concern? All four intake ports were like this. Some worse than others. I had to remove the carbs to clean them and notice this after removing them.

As part of my crankcase breather housing job, I had to remove the carburetors and V-Boost intake manifold assembly (VIMA). I found what I needed as far as removing the carb rack on the forum, but as far as I could tell, the forum lacked a How-To for removing the VIMA. So here goes: First...

I removed the intake manifolds from #3 and #4 cylinder heads. The right side.. Oil was leaking out of the bolt holes for #3:ummm: but not #4. Why would these bolt holes be connected to a oil gallery or return?:ummm:

There is a seller on ebay offering the covers shown below. I was interested in getting a set, but there was no indication of material used in the ad. I contacted seller and they finally got back to me. They indicated material was 0.6mm thick. This converts to .0236" or standard gauge...

I can't find this torque spec anywhere....does anyone know what it is? Thanks

Ok so I just bought a 97 max with 14000 miles. I had it running but it was idleing rough so I decided to clean the carbs. With the carbs off I looked down into the motor and noticed a small amount of green fluid sitting on top of the intake valves. The coolant level is still full and the oil...

has any one tried running without intake duct? I have a marks exhuast, needles shimmed, 152.5 jets, K&N air filter

Hello Since the carbs are off anyway I removed my intake ducts today to clean everything up. Haynes says to reinstall with new gaskets every time. I'm wondering how crucial this is (old ones lok in good shape to my untrained eye). If it is crucial, can anyone find a part number? I couldn't...

As some of you know I'm stripping my bike down pretty much to the frame this winter, I'm down to engine removal this weekend. I'm also a jet engine Mechanic so I know my way around a tool and a manual, with that said I think I take very good care of my bike, but when I removed the rubber boots...
