    Misfire and backfire on decel - '88 Vmax

    Before I go through the process of pulling the carbs, I thought I'd solicit the group for some advice. I bought this '88 Vmax from a co-worker who was "throwing in the towel" as he couldn't get it to run properly. The symptoms are a stumble coming off idle and a misfire (often triggering a...

    Fork Brace Identification

    This fork brace came with my 1988 Vmax. Anyone know the manufacturer? Any reason why someone would remove the stock brace and replace it with this one? Is it an improvement over the original? Thanks for your help.

    The Vmax seat thread! The all seat thread!

    I'm working on reconditioning a 1988 Vmax and am currently focusing on the seat. It's in great condition other than a few cracks in the pleather on the "hump" Does anyone know if you can buy a new cover just for the "hump" piece?

    Oil Level Sensor Removal

    I'm having some trouble getting the oil level sensor out of my '85 (prepping for paint/powder coat). I have the oil pan off, I've removed the obvious mounting screws, but it doesn't want to come out. Inspection on the inboard side of the oil pan shows what looks like a snap ring around the...

    Needle valve clip attachment

    Anyone got a good trick for getting the needle valve clipped to the float after installation? I've tried installing the needle valve and float together, but the physics don't work out. It's easy to install the needle valve and then the float, but getting the clip on after installation seems to...

    Mixture Screw Extraction Success

    A passable set of reverse drill bits can be found at your local Harbor Freight. The extractors came from eBay. There are many sellers of the exact same set, but for reference, this is the one I bought...

    Mixture Screw Extraction Success

    Glad the left hand bit worked for you. I was hopeful, but this one was tight. I soaked it in PB Blaster for a week (I was on vacation) but ultimately the brass screwdriver slot let go...leaving nothing to with which to apply torque. I used a 1/4" left hand bit to ensure a good center dimple...

    Mixture Screw Extraction Success

    Those of you who have battled your way through this can probably appreciate the photo. What an ordeal. Happy to say that it ended in success. I tried several different methods including left hand drill bits and EZ-outs, but ultimately used a "hammer in" extractor to finally get my stuck...

    Do you happen to have any literature on this recall? I can't seem to find any information about it on the 'net.

    5th wheel/pinion design change

    Anyone know why Yamaha moved away from the original 5th wheel/pinion design (gear teeth engagement) to the new design (dog/slot engagement)? Both designs seem like they'd work okay. My original '85 5th wheel/pinion gears still look really good after 32k miles...any reason I should switch to...

    2nd Wheel Id

    Anyone know why these two "2nd Wheels" are different? One is from my '85 and I believe it is original to the model (bottom). The other comes from an unknown year spare transmission (top). Is this a design upadate? If so, what is better about the top design?

    1985 Vmax 2nd gear repair - Looking for advice from seasoned techs

    Thanks for the feedback guys. Looks like I'm in the market for some new gears, a good condition used tranny, or I'll just bite the bullet and get them undercut.

    1985 Vmax 2nd gear repair - Looking for advice from seasoned techs

    I've put about 2000 miles on this bike since I bought it used from a dealer. Its performed very well until recently it started "ratcheting" in 2nd gear under heavy acceleration (near peak power). I'm familiar with the issue from reading these forums and was prepared for it when it started...

    Hard accell...Slip/bump??

    Can you explain this further? My '85 just started "bumping" in 2nd gear under hard acceleration. I'd like to be sure tranny wear is my issue before I tear a well running engine apart. Thanks Chris
