Hello, if you have someone near who has a similar set up can you try your CDI box on their bike to see if it works.?

Hello MM , yes I have checked them following the guide in the workshop manual. Thinking that it may be a loom issue, so I plugged everything in except the lighting / indicators and the oil level switch is permanently on. Removed it and tested that as well and the readings are as described in...

Another update and question. Investigations /work done so far. I have tested the original vboost ecu and a spare I have on a running bike, a number of times, and both operate as they should. Tested the motor and a spare on the good bike and all works as it should. Removed the inlet manifold and...

Thanks for that , I have opened it up and it appears to be covered in some sort of gel so not sure if that is standard or has been repaired in the past? Regards Chris.

Hello, just a quick update. Plugged the vboost system into a known good running bike loom and all works well so Seans tip about the control box looks to be right. Now to open it up and see what can be done. Regards Chris.

Thanks for the advice Sean, I will check it out and let you know how I get on . Regards Chris.

Hello everybody. Some information would be appreciated. I am rebuilding a max from boxes of bits and have got to the point of installing the v boost system. The system was working ok when removed about 2 years ago and dry stored until now. I tested the system by turning on the ignition and the...

Welcome, Radioguylogs is correct that there is a wealth of help and information on here and a few based in the UK as well. And don't forget that the only stupid question is the one you don't ask ;) ;)

Looking good , although I am not a lover of tribal / flames I think they work well in this instance as to have just left it plain would have been a bit plain ( in my humble opinion !!)

Hello , the wire fits inside the fly wheel retaining bolt . I believe it acts as an oil thrower so the straight bit goes inside the bolt and the curved bit sticks out . Remember to hold the flywheel on the large "nut" while loosening and tightening the bolt. You should not disturb or dislodge...

Hello , any more detail on what the problem / fix was would be helpful. Regards Chris.

I thought that the workshop manual states the crankshaft should be turned anti clockwise ? maybe try that first . I would also rotate the crank using the larger (32mm?) nut not the centre bolt.

There are a number of complete units on Ebay UK for various amounts. Regards Chris

Hello , I spoke with Ian at PDQ for replacement springs for my 43 mm forks on my trike. Very quick response and helpfull. Regards Chris.

Hello , I have a Gen1 vmax that has been modified. It has Yamaha R1 forks fitted to billet ally yokes , standard R1 blue spot callipers etc so basically an complete R1 front end with billet yokes. I believe a Suzuki GSXR 1000 would also fit with billet yokes. Mine has also had a 17 inch rear...

Hello , if it will start but not run maybe check the fuel tank level and filter for blockage. Check the fuel pump is actually pumping fuel by removing the hose from the pump outlet and fit a pipe to a can then turn on the ignition to see how much fuel it shifts. A quick test for the starter...

Hello , I wonder if there is a restriction in the tank air vent slowing down the flow of fuel . Remove the fuel tank cap and try again . Regards Chris.

Hello , According to my manual oil quantity for change including filter is 3.8 ltrs ( 3.5 ltrs without filter and 4.7 ltrs after rebuild) Coolant capacity is approx 3.25 ltrs made up of 50% distilled water and 50% anti freeze . Regards Chris.

Hello , I made the assumption that the cops had been purchased with the plugs / mini loom as part of the kit and not just purchased the cops. The plug / loom can be purchased separately if required . The sets I have seen are advertised on EBAY UK but are manufactured in the USA. His EBAY name is...

Hello , My understanding of the situation is as follows. Gen 1 vmax up to 1989 used an analogue control unit so needs resisters fitted to the cops to give the same resistance as the original coils. Without them fitted it is possible to overheat and damage the ECU which will be far more expensive...
