I bought a 1997 VMAX 700 triple with low miles that runs great. It seems to use a lot of gas and oil, even more than friend's Yamaha triples. It even fouls
plugs at least every 100-150 miles. Since gas is now over $ 3.00/gallon and
oil is way up, does anybody have any suggestions on how to lean it out a little without burning it up? What size should the primary jets be on this model? Thanks.
 
Been covered on here a lot
142.5 main jets right across
drop the needles 1/2.
 
Mine was identical to yours when i first bought it it was running really rich killing plugs hard on gas and oil etc. I am at sea level to 2000ft temperatures to -25C. I ran mine 140 pto 138, 138 down 1/2 clip on the needles and 40 pilots also the float heights were way out from the factory 13.3 +/-2, the reed spacers or reed stopper mod makes a big difference to throttle response.
