HPI BAJA engine advice

[ESC-RC]

Hi guys.Looking for a bit of advice.The engine on my baja is running well but how much smoke is normal out the exhaust.And their seems to be a slight echo as well at idle which goes out as I put the gas on.Im useing 2stroke motorcycle oil that I got at a local petrol station.I think the buggy is sound but just wanted to get a bit of advice before I go and run it full throttle.Tried to put videos of it on but it would not let me.

Theres no metric for smoke. Different oils burn at different rates, as well as ratio being a depending factor. What I say is too much or too little smoke may, or may not be fine. If your confident in your tuning abilities, then the amount of smoke doesn't matter. If you have a strong idle and a smooth transition to mid through high rpm then you are more likely fine. Again smoke level doesn't really matter.

If it ain’t smoking it must be broke ?


could you please provide more info what oil gas mixture are you using ?? Do you have any videos of it running ?

Thanks guys.The buggy does have a strong idle but have not gone above quarter throttle with the engine so can’t tell if it’s ok at mid to full throttle.The car was build in 2012 and a tank put through it at low throttle and then not used till May of this year.I put 80 ml of oil to 2 litres of gas.I have videos of it running but don’t know how to put them on the forum.?.

Your mix is 25/1 that's plenty oil ?? as long as you have decent oil you good to go ?? 28/1 - 35/1 is what most of us here run with premium oil??
