    Ignition Pickup Coil

    I had a post a while back with questions about this same issue With no response. I hope this one does better. Has anyone ever had their ignition pickup coil fail? If so can it cause misfire like running off timing or does it just stop working altogether? I’m rebuilding the carbs for the third...

    Cam timing

    So, first, a little back story... Beginning of summer I rebuilt the motor on my '94. I had pulled the motor for second gear fix and found the oil pump o-ring issue and some main bearing damage. I also discovered that somebody had been in the motor before. Both cam chain tensioner guides were...

    Camshaft Timing

    Hi guys, I am in need of help again. Two of my front cylinders are not working. Maximum compression is okay, current flow is okay, spark plug okay. Rear engine works but really hot. Why do you think the front camshaft is not working? Can I interchange the camshaft of the front and...

    Oil light timing?

    Hey guys! So whenever I'm going up a hill and accellerate from 2-3k, my oil light comes on at around 4500 - 5000 rpm. Is this normal? I mean if I just steadily go up it rarely comes on, it seems to be triggered by acceleration If I'm going downhill I can get to 6500 before it comes on, or...

    Measuring Valve Clearances

    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...

    Timing chains.

    126,000 miles is making me think about wear issues. One of the things I'm thinking about is the timing chains. They are original, as are the chain tensioners. I believe these camchains self-adjust - I seem to remember that they self adjusted after the motor was revved up to like 5000 RPM...

    Balancer Shaft Timing

    I split my cases to repair the notorious second gear issue. Since getting all my parts back from Sean today, I started reassembly and came to a snag in the process. My book (clymers) says there is supposed to be a timing mark on the main drive gear on the crank and a mark on the balancer shaft...

    Cam timing marks on cam caps?

    See Photo The book says to line the appropriate cam index holes up with the mark. On my 99 there is a thin line that looks sorta of like a casting line that is straight up 12 o'clock. Just to the right of that (for all caps, they're all identical except for the location stamping)...

    Anyone got a pic of the crank gear timing mark?

    I can see a timing mark on the balance shaft, but I can't see one on the crank gear. The genuine and aftermarket manual I've got don't have any good pics. There is white paint on one of the teeth. I scraped it off a bit but couldn't see an indent.:ummm:

    Finally the cam timing specs.

    I used a degree wheel and piston stop to get true top dead center, which by the way is spot on with the timing mark on the rotor. Intake: Open @ 11.5* BTDC Duration 230.5* Close @ 39* ABDC Lobe center 103.75* Exhaust Open @ 41* BBDC Duration 235*...

    Timing intake, exhaust cams

    Gen 1 Main Pickup Coil Signals, Ignition, Timing Data from the VMax Guru

    I e-mailed Tim (the VMax Guru) a while back with a few questions on the gen 1 pickup signals. What I was hoping for was an easier way to get a 4 to 8 cylinder tach to work with the VMax. My idea was quickly shot down, but Tim did provide some nice data that I asked him if I could share with the...
