Im running 2004 vario on cng for last 2 yrs... Almost 55000 kms on cng... Total mileage 120000 kms...
Replace cvt fluid after 30k instead of 40k... Keep the airfilter clean... Get the spark plug adjusted for cng.... Never convert to cng till engine is warm enuff...
Most imp...Get the idle rpm adjusted to exact 1100 rpm... Nothin more or less...
Ur vario is gonna b good on cng...
Take good care of trnsmsion and nuthinz gonna go wrng... I instaled cng after the car had already done 57k.... And till date no issues... Jus a lill extra care...
Best of luck...
