Fuelie engine question .

[Barber213]

Good evening to all . I currently have a Fuelie engine and wanted to know how reliable they are . . It’s a Rev 4 Bolt 30.5 cc 2 stroke . It came with my king motors baja . I’m currently upgrading it and wondered if I should upgrade the motor too . An is factory team differential 7000 fluid by team associated good for my differentials .

thats not a real fueliee engine. you can probably even spot a spelling error on the sticker. thats a clone engine so no it's not very reliable. i would run it till it breaks and then upgrade as i have done with the rovan engine i had in my baja

Zenoah makes a way more reliable engine, China's attempts are hit and miss. Your oil is good for a 1/8 scale diff, pretty sure the spec is 100 000. 7000 would have you spinning on wheel often.
