try mo sir spark plug reading. rev mo ng 5k rpm kung san nananablay, for about 15-20 secs. tas patay mo engine na hindi ibaba ang throttle. saka ka mag read. make sure well ventilated ang engine.
Since I got this bike.....I got no issue whatsoever.....long rides ..no issue. But at again, as time passby and as you daily warm-up the bike, may mapapansin kang kakaiba. It all started when I noticed na isa sa apat na exhaust manifold ay hindi masyado mainit, so I was thinking....ahh...palitan nang sparkplug! and there was an instance din na during downshifting, may tendency na mamatay ang makina, that you need to rev up para maiwasan yun. Well....isang tao lang ang pumasok sa isip ko : ARIES" THE SHOPMAN"! he recommended ang NGK Iridium(CR8EIX), medyo mahal but it's for long term use! One thing about him is, he will still check yung bike for other things para nga naman isang trabaho na lang. Lo and behold...may issue din pala ang Carbs (which was never opened since I got Gray Wolf) plus nagpalit nang Rectifier at hindi tama ang reading ang Voltage Meter. ARIES THE SHOP MAN...is the Man!!! He will be really meticulous in fixing your bike, and hindi niya sa iyo ibabalik yan until 100% sure na walanang Covid ang bike mo! He pulled out the bike last Thursday evening and kanina lang niya binalik ! Hindi niya bibitawan ang bike hanggat 110% sure siyang ayos na! Yes...the bike is for sale due to an upgrade...but nw...am having second thoughts na ibenta at nag 'RESURRECT" si GrayWolf!!! lalong bumangis ang takbo! Sa mga nagpapagawa at magpapagawa kay Aries...be patient, trust him and have faith sa work niya. He doesn't have any assistant at all...solo siya and if you will see mga nakapilang bike...you will be amazed how he can he managed at all...SUPERMAN !!!! And with regard sa "Labor Cost"???...wow!!! alam nyo na!!! Very reasonable! Lastly, he is a man who thinks of 'QUALITY ad NOT of QUANTITY'. He is a man of passion sa work niya as a bike Mechanic coz' di katulad nang iba...just for the sake na maayos (temporarily), mabilisan para makarami! Siya?....QUALITY !! Na pag inayos niya bike mo...for sure matatagalan bago mo ibalik sa kanya fopr another repair or check up! I salute you sir !! ARIES "THE SHOPMAN...THE LEGEND...SUPERMAN!! STAY SAFE AND GOD BLESS!
