How reliable is the Fuelie engine?

[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 30.5cc 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.

I thought the engine name Fuelie was what just HPI used and is a zenoah but this 32 engine that is used in a HSP has Fuelie also but with a yella sticker instead of the red that HPI uses.

The 30.5 is the best engine KM makes. Run it till it breaks!

I have zero knowledge about KM engines..i did do a google search and i still haven't any clear manufacture details about it.
I did find this 30.5 kit for a rovan.

I did find the KM engine here, i guess the name Fuelie is used on many brand engines.
