    Tach only works when I tap it

    In the end, I took the tach apart and resoldered the electrical components. You can get the circuit board off without having to remove the gauge needles which is pretty cool. The tach is working fine again.

    Tach only works when I tap it

    Hi, As topic title. The wires are good and clean, Tach is dead until I gently tap it. Then it`s just fine. When the bike sits for more than a few minutes, I need to tap it again for it to work. Is there any way to fix this? Thank you.

    2003 Vmax 24,xxx miles Odd Neutral switch behavior.

    Probably a wire indeed. If you have a multimeter, find the side of the turn signal fuse that goes into the bike. This is the side that has 0V between battery ground and that side of the fuse with the ignition on. Next, turn ignition off and keep the pins of the multimeter as they are (1 side on...

    EFI conversion on a Gen-1

    That`s a lot of questions in 1 post :). You first install both injectors into the aluminium t-connector, then add the manifolds and across the manifolds there will be two aluminum plates securing the two manifolds together. That will be the same style as you can see in previous posts. The...

    EFI conversion on a Gen-1

    There is about 7mm space between the two injectors so a T-shape connector is the only thing that fits. You should see it as a subassembly like the Vboost manifolds :). Fuel pressure is about 60 PSI.

    EFI conversion on a Gen-1

    Thank you, I will use values close to those. In the Netherlands, we use fuel which has around 5% ethanol so I have account for that as well. Ethanol is heavier so my flow rates are slightly lower. It doesn't mattter that much however, the ratio between the two injectors is what mostly matters...

    EFI conversion on a Gen-1

    Hi! It`s been a while so I thought it was time for an update. I`ve done a lot of work in the mean time and decided not to just move the injectors closer to the intake manifold, but to use two sets of injectors. The second set I got from a CBR 600 PC41. The injectors close to the cylinder head...

    V Boost Controller issue

    You just resolder everything on the back of the unit. Vibrations can crack the soldering points to heating them and resoldering them fixes that.

    Coolant drain from block

    Number 9 on the picture below. Once screw 10 is removed, youc pull plate 9 off and find number 11 behind it.

    Battery reconnect problem

    Like Fire-medic says likely the starter solenoid. Disconnect the two leads from the starter solenoid inside the red circle and isolate them (for instance by putting tape on each of them, do not tape them together). Now you should be able to connect the battery without the starter motor engaging...

    Requesting a few pictures of the speedometer with rear cover removed

    Correct, and the chrome ring will definitely get damaged when opening it. But you can rotate the ring so the damage is on the bottom where you don't see it. The white plastic tends to chip so make sure you clean out all particles before reassembly.

    Bad sounding engine. Big end gone?

    I just asked and the sound is coming from the bottom of the engine. I`ll ask him to indeed drop the sump and take it from there. Thank you for the suggestion.

    Bad sounding engine. Big end gone?

    Thank you Fire-medic, forwarded your reply, let`s see if the sound can be localized.

    Bad sounding engine. Big end gone?

    Hi, A Vmax rider from the Netherlands reached out to me with this video: I`m afraid it`s a big-end failure or something similar. But before I tell him to get a new engine I`d like for you guys to also have a look / listen and tell me what you think. Thank you. Edit: I`m sorry this should...

    EFI conversion on a Gen-1

    Hi Parminio, Thanks for the detailed response, it seems you know your stuff :). Some of the abbreviations you used (like IROC) were unknown to me coming from the Netherlands but I did my homework. I understand your point that air has mass, and although the MAP pressure might change, it can take...

    EFI conversion on a Gen-1

    Hi there, time for another update. Over the last months, I`ve been driving and tuning the bike. One of the main things I learned is that only using Manifold Absolute Pressure (MAP) to calculate the fuel load worked great for the 0-10% TPS, above it the MAP values did not have enough resolution...
