    Watered-down fuel

    Bike has been running a little rough for a while. Smooths out and runs good in the upper RPM with a little popping from the exhaust when engine braking. I just figured it was time for a shotgun or a carb cleaning. Been a couple years since I had to do it. So, as part of the procedure I normally...

    Spark plug soaked in fuel, stuck slider?

    I have a 2000 Max with 73,000 miles on it, stock carbs, jets, and exhaust. For the last 4 months, it has been running as if one or two cylinders are not firing. At a red light, the idle will switch from perfect to a stutter (like a Harley), then back to perfect, within the same red light...

    Fuel issue

    Hey guys I need some direction, I have a 1988 Vmax that I am working on for my friend, he asked me to help get it running and what I found was a tank with a lot of water in it, a fuel filter that was clogged a fuel pump that didn't work and ungodly dirty carbs. So long story short I have...

    Fuel leak and white smoke

    Hi guys, the last time I had started my 2005 vmax was a couple of months ago. I started it today. Started fine. Left it running in the garage and went inside the house for some breakfast. Came back 15 min later, the bike was still running but there was a bunch of gas on the floor, and white...

    Fuel tank not venting...

    My Vmax (2005) keeps stalling about 7 miles after a fill up. I might be overfilling the tank, and plugging the fuel tank vent line. I disconnected the vent tube, and could barely blow through it. Is the gas cap supposed to also be venting? After I stopped (it's happened twice now) and took off...

    Quick Comment - Preventive Maintenance - Fuel Lines

    Just a quick comment... Last weekend I took a ride to Dallas (3 hours away). On my return, my bike stalled about 5 times, but eventually re-started each time and got me home. I suspected my fuel pump, which I took apart and found everything (including diaphragm) in order. Fuel filter is...

    Kink in fuel line

    Anyone have success in using a normal (nonOEM) fuel line for part from tank to fuel filter? My bike would start and then die straight away. I noticed a kink in the hose, since I am not using the stock that has the u shaped bend. It has lasted a little over a year, but not sure how the kink...

    450-Mile Ride Today + Possible Fuel Pump Issues

    I synced my carbs and installed new rear brake pads this morning, and headed south 200 miles to Dallas, TX - just for fun. Perfect weather! BUT... on the way back, after about 70 miles, I felt the engine lose a couple cylinders, followed by the rest. I coasted to the side of the road (in the...

    Fuel pump issue

    Hey all, my '85 max's fuel pump doesn't work like it should on the factory wiring. I have eliminated the pump it's self by wiring it directly to the battery. It pulls and primes on the battery but when on the key it sounds weak and don't want to prime. Has anyone ran a bypass to a relay or...

    fuel needle thread pitch?

    I tried but could not find reference to the fuel/air needle adjustment screw thread pitch. I have come up with a size to (to the best of my ability) but I was hoping someone else here has found out by experience for sure what the thread pitch is. My plan is to chase the threads in the carbs I...

    22L/100km fuel consumption on the racetrack!!!

    Hi guys, few weeks ago we went to MotoGP in Brno Czech Republic and we had an opportunity to ride on the track. In the camp right before the ride I topped my fuel tank. For 3 laps on the track (one lap is 5km) and 5km of highway ride to the first gas station, my Vmax burned 4.5 L of fuel. That...

    Cleaned Carbs and replace fuel inlet valves. Now no fuel is getting into the bowls

    As the title states I ordered 4 rebuild kits which consisted of O-rings and fuel inlet bodies/valves. I noticed the new inlet valves are stiffer then the original ones (figured the originals were worn) and they hold the floats in the low position when turned upside down. This is uncharted...

    A lot of fuel when I pulled the slide

    What's up guys? I've been away from the forum for a while. My vmax has been in pieces in my garage for the last six moths since I returned the carbs to Sean that I borrowed to help diagnose my problem. That's a long story..... but anyway my coasting enricheners were pretty rotted out so I...

    Ethanol and fuel stabilizer

    Some folks think that using fuel stabilizer is only for off-season storage. While this may have been true in the good old days of pure gasoline, its not at all true anymore in this day and age of ethanol bastardized fuel. Unless you enjoy pulling carbs and cleaning pilot jets, etc., here are...

    Fuel pump goes into high speed chatter when hot

    Hello guys, was hoping someone has ran into this before. When the max gets up to temp and the fuel pump is hot as well, it starts hyper cycling and doesn't supply enough fuel to carbs to keep idling. This happens with fuel cap off and I checked filter is clear. Only happens when fuel pump is hot...

    A Fuel Question?

    Living in the Philippines, most of the forecourts offer a choice of either 91 regular or 95 premium. Some also have 97. All the fuel here has an additive of 10% ethanol. Unfortunately, they add a horrible red dye to the fuel which causes carb contamination problems over time. Since I have owned...

    Aux Fuel Tanks mounted on radiator

    The fuel reserve system was not operating, so I relied on the odometer for fuel stops, but found that really depended on my riding habits. All bulbs tested OK during the start button sequence, so I traced it back to a faulty fuel sending unit using a resistance check. A used replacement was...
