I haven't ridden my max in over a year (yea I know!!) and started driving over the road in April of this year. When I came home in June of this year I out my Max in the shop to have the carbs cleaned. I ordered a turn signal relay from Python Motorsports before I went over the road and changed...

Hi folks: My 1986 Yamaha FZX700 (Fazer) fuel pump is dead. Replacement cost is $300. Now, the VMax fuel pump replacement costs $140. Other than mounting issues for the VMax pump on the Fazer, is there anything else that would prevent the VMax pump from working on the Fazer? Thanks very...

Out riding today and pulled up to a stop light. Bike is idling fine and when the light turns, I proceed through the light, only to have the bike choke when I give throttle. I pull off the side of the road, the bike will idle but die when throttle applied. Turn the bike off and let it cool for a...

While my carbs are out to Sean I was thinking about checking to see if my V-Boost is opening all the way. I am thinking about having it all time V-Boost so now with the carbs off would be a good time to check things. Is this my fuel pump connector? where the arrow points?

Hey guys, I don`t know how it happened, but my fuel pump took a sh!t on me today . When I took it apart I noticed a small wire had worn off the thin insulation and burned off and un fortunately I can1t solder it back but when I tried to put power to small wire that was sticking out of the...

I used a hvac vacuum pump to pull brake fluid through my clutch system. I primed a close to dry system in a few minutes. But now my slave is leaking. Did I fry the seals in the slave pulling to much vacuum? I found the system almost dry with the master locked up. Guess it must have...

The fuel pump took a dump on my 85 max. I was going to order a new oem until I figured out they get $150+ for one! Anybody have a good suggestions for a replacement that will be reliable and lower cost. I have seen the junk crap at the parts store that last 2 days, so thats not an option...

Hi all: Does anyone know what Yamaha VMax part diagram the Max's fuel pump is located in? I'm having a hard time finding it. Thanks. Elimax

Ok I finally got time to check my fuel pump. I put the output into a bottle and filled a 500ml bottle in 20 seconds. That should be plenty of fuel I believe. Fuel tank vent is not clogged and filter is new. My problem is I can run up thru the gears to redline untill I hit 4th. Then it breaks...

All right for all you guys out there who's bike will only run when the fuel switch is in the reserve position..... Check Your Light Bulb!!!! :bang head::bang head: When you first start the bike the light should come on. Mine didnt. :bang head::bang head: I never really paid attention to it...

I noticed on the youtube video, "The Vmax Thrill" when the ignition is turned on, the fuel pump cycles for what seems like only half a second, while in comparison, my 85 fuel pump cycles for at least a couple of seconds and the "ticking" sound of the pump seems much slower than the VM in the...

HI. I have a 1985 VMAX. And I am having a series of problems and I could use some advise. The biggest problem is the fuel pump will only work if I have the switch set to "RES". If the switch is set to "On" the bike will run the bowls dry and quit. Also the VBOOST is suspossed to cycle once...

Hi folks: I've seen the term "accel. pump linkage" cited on the forum but don't know what it is or where it is on the Max. Anyone know? Thanks. Elimax
