Finally sorted it ,disconnected the ignition vac switch and blanked the manifold off now perfect idle and perfect transition to on and off the throttle .What I think was the problem was too much advance at idle and with open v boost uneven pulses giving the weird Jerky uneven overun

Looking at the settings I would say califonia settings were closest for the jap vmax ,I may try setting it up with an 1100rpm idle speed rather the lumpy 950 rpm mine has at the moment.

The pilot circuit is clean and the pilot jets are the same as a full power machine. I was wondering if the ignition module had a different advance curve for the japanese market as it has a speed limiter built into it which others do not . I am going to try it with the vacuum switch...

I am trying to derestrict my japanese import vmax ,I have replaced the slides and bored thru the v boost block off pipes .I had to put the needles on the bottom clip and have the pilot screws 4.5 to 5 turns out to get an acceptable idle . I bought some UK spec idle jets that were exactly the...

Problem is the jap speedo has part of the restrictor system built in to it .It would mean changing the cdi and altering the wiring to suit to get round it which is a real pain

Good thinking that man ,that may be the issue. As a quick fix I have managed to reposition the needle so it is further up the dial.As long as when I pass speed cameras I am going slower than indicated I am happy.

I am in the process of resurrecting a japanese import vmax a 89 model.The speedometer was damaged but a virago 750 speedo had the same top speed ,the jap import has a lower top speed on the clock. I managed to get the speedo opened and replaced the face ,I pre tensioned the needle like it was...

We have a similar problem over in the UK, scum on stolen bikes in packs bike jacking other bikers machines.They had to change the laws re buying battery acid as they were throwing it in people's faces to rob them. Our police are useless at stopping them and get prosecuted if they knock one...

The japanese clock has 4 extra wires ,3 in a block and a blue red in a bullet connector that runs to a circuit board that is controlled by a disk on the speedo needle .

My latest purchase is a japanese import 1200vmax. Converting to full open v boost etc is no issue ,however the japanese speedo is damaged .They have a restrictor built in to it ,I have a none jap mph speedo and the restrictor circuit board from the clock. I have read on a xjr yamaha forum...

thanks for the info,i will be investing in a hid kit,seen loads fitted but people seemed more fixated on the light colour than the output & function of the light,now i know a stock reflector will work i will proceed

i am trying to find a suitable way of uprating my max headlight,it has the double relay mod .however the beam patten is useless on either dip or main,tried another yam reflector from a virago ,just the same.i ride on back roads & every car coming towards me has superbright lights,they dont...

if your after hassle free performance its the busa ,bomb proof .the zx12s ride better as a sports bike but occasionally the crank spits out its dummy & wrecks the cases.the zrx12 is quick but a bit like a vmax in its dynamics without the carisma.the bandit is just dull but fit the gsxr1100 cams...

as the bike has not responded to the usuall subjects,how about loosening the rear cylinder exhaust pipes ,see if the collector box as collapsed blocked baffles.has the bike had a new flywheel starter clutch fitted.the early 2 pickup & later single ones probably vary.you will be getting a spark...

could be a number of things,carbs out of balance,slight blockage of idle jets.best thing is to check oil levels etc,if there is no local vmax gurus ,record the noise on a decent camcorder ,post on you tube etc & post a link.someone will diagnose & probable ease any fears you have.
