valve

Is there anyway to repair the stock drain petcock valve? I have a 91 and the PO did not care for the bike properly, so this has been a work in progress. No matter where I turn this, it still drips coolant after the bike has cooled down. I see that there is a little mark on the housing. I...

Hi all: I hope everyone's doing okay out there. Question for y'all about installing some new 90 degree valve stems I purchased for my Max. They are from Moto-D Racing, and can be seen at this address...

For you motor gurus - Damon just posted something interesting in another thread - "Erratic idle when hot" Quote - "When was the last time your valve clearance checked and/or adjusted? I have seen when a valve adjustment was needed the idle rpm & vacuum readings would be bouncing all over...

I am about to dig into my first ever valve job. I have condensed naughtyG how to threads on the clearances to a word document I would gladly email out for anyone looking for a "printer friendly" version. This is my first time ever working inside an engine so I have a few things I need to ask...

Below is a link to a valve shim source that was posted on Venture site. Current pricing is $3.88 per shim with a flat rate shipping charge of $9.99 for orders under $99.00. Free shipping on orders over $99.00. Compare to Yamaha MSRP of $15.49 each. The VMax's/Ventures uses 25mm diameter...

Fellow Vmax enthusiasts, a scenario/question I pose for you; When setting the cams for valve clearance measurement I followed the Yamaha Manual procedure as follows; Set T1 mark, make sure rear cams have timing marks pointing up and Cyl 1 is at TDC Rotate 180 Degrees and Cyl 3 is at TDC...

A few years ago I put 1300 venture carbs on my vmax, I swapped everything over(including the butterfly valves) from the vmax carbs to the venture carbs. Now that I'm rebuilding the carbs and putting in morleys jet kit in I noticed some of the butterfly valve screws are stripped. I figure the...

I picked my motor apart. Valve seats and valves did not look very pretty. After lapping the valves, the contact area between valves and valve seats measure about 1.2 - 1.4 mm wide. The manual specs a service limit of 1.4mm, and a desired seat width of 1mm. Do you think it's worth the...

When you need em, make em,

hi for my first post i have a great question, does someone know the sizes of all the bleed valves on our vmaxes (rear , front and clutch) ? i saw this http://www.speedbleeder.com/ what do you thonk about it ? thanks for your help

I need to replace my valve cover gaskets so, I figured it would be a good time to check the valves. I asked Sean if his valve shim kit was available. His response was ,"I wish". He is having problems getting the kits returned. I'm not sure of the whole story or who has these kits. I...

What side is the valve stem on a stock setup? I assume the front is on the right side (sitting on the bike) as most are due to sidestand lean but on the rear there is more room on the pumpkin side, so i'm just curious which side yamaha put it on? thanks!

I think I'm losing a little oil from the gasket on cylinder 3 (according to Haynes manual, rear, right). I've cleaned it all up today and will apply talc when totally dry to verify that's where it's coming from. I'm questioning exactly what needs to be done to replace it. The Haynes manual...

I've read somewhere that the valves tend to tighten up when they go out of adjustment on these motors. Is that right? It would seem that if that's the case, the engine would pull more vacuum? If that happened, wouldn't it then pull the slides and needles out earlier? It seems my bike is doing...

Man i will never use a ratchet wrench again on these bolts man. :bang head: Outer bolt rear lift hand side. I went up to the yamaha dealer ship with some pictures they said the heads need to be pull off to remove the broken bolt at a cost from $600.00 to $900.00 to repair. Any help on the...

Hi I just purchased a 1998 black vmax with 15000 miles. The bike has cobra 4 into 4. The left rear cylinder(right side rear exhaust) will make a piece of paper slap the exhaust(suck it in). Hoping for the best. Hopefully valve out of adjustment. I didn't think anything major could be wrong with...

Hi everybody. I have a 1994 vmax with 35000 miles on the clock that suggests it's time for some maintenance I bought the bike last autumn as you can tell from my vmf join date. Immediately I noticed greyish smoke from the exhaust when I rev up after a bit of idling at traffic light or warming...

I'm waiting on Sean to respond but does anyone else have valve shims I can Buy and have overnited? Need: 2x 2.80 3x 2.75 1x 2.70 Thanks!!!

I want to remove the valve cover on my 1993:ummm: to paint it and I am just wondering if there is a trick to getting it out? Doesnt want to clear lifters. do I have to lower engine?

I need some sort of flexible extension to screw onto the valve stems to check the tire pressures. The VMax is a pain in the ass, but the Roadstar with the spoked wheels is a true horror show... Or else could someone recommend me a accurate pressure gauge that has a filler that will snake...
