    tach and temp gauge lens

    Anyone know where I might be able to get the lens for the tach and temp gauges? mine are crazed, maybe even cracked. I tried buffing them out and that helped, but after sitting in bright light for a while the cracks show up. I finally figured out why; the cracks are small but when left in the...

    'VBoost' tach

    After reading the thread about the 185 mph speedo for an '85 it brought back a memory I thought I had about the first years. I could have sworn my buddies '85 or '86 had the words 'VBoost' on the tach around the 6000 rpm mark. Am I remembering correctly or did I have a little too much fun in...

    Fuel Pump issue and Tach Isuues

    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...

    Tach conversion

    I know this question has probably been asked 100 times, but here it goes. I'm wanting to put a 5in monster tach on the bike. I want the Autometer tach with shift light, but I cant find one that is adjustable down to a 2 cylinder application so I can tie straight into the factory tach lead...

    Tach and Speedo switch?

    I was looking around at some pics of Vmaxes with monster tachs on them. It made me think.....since it would be more vital to have a better view of the tach rather than the speedo, would it be possible to mount the tach in place of the stock speedo(i know this has already been easily done) and...

    I started my 1985 vmax today after painting the side covers and replacing all gaskets.There is no tach or temp gauge.The lights on the gauge cluster work as do the neutral light and signal indictor.Where is the best place to start? Is there more fuses other than the 4 under the seat? Thanks for...

    Aftermarket Tach hookup

    Ok I installed my new tach but when hooked up to the stock wire it just did not seem like it was just right so I tried hooking it up to the common wire for the coil fairly close to the coil and that works not at all I was wondering if this is b/c I installed the COP or am i missing something?

    Tach stopped working

    Riding in to work this morning I hit a series of very bad bumps ( which is unusual because normally the roads here in Quebec are smooth as glass :biglaugh:) The motor then felt like it was running on two cylinders and the tach stopped working. It did this for about 1/2 mile and then came back...

    Tach redlines after heavy rain

    Ok, I don't ride in the rain if I can help it, but my 99 Max had a Texas Frog Floater of a rain descind upon it one afternoon. When I fired her up to head off, the Tach redlined. It was obviously an electrical issue and did not affect the engine or Vboost as far as I could tell. When it dried...
