Just to manage some expectations here, be prepared to find out that your engine may not be up to par with some of the better ones.
The Comer c50 is not a racing engine so there are wild variances in performance. There are rumours of top level Bambino engines going for 5 figures...
In terms of an engine, even a new one out of the box needs 10 hours or so, a fiche, possibly selected carb to get the best out of it. Which obviously means added costs for practise, tyres, fuel etc.
Feel free to touch base with any questions as we've had 2 years of Bambino now. We refuse to throw money at it as there are more gains to be had later on in my little one's karting journey...
Hey man, I was interested reading your post as i am just prepping my 4 year old to get into the Bambino level.
Being so new to this i didnt realise there would be differences in engines at this level, are you basically saying that its luck whether or not you get a good performing c50 if bought new? That surprises me as naively i thought each engine would be the same. I know later on in different categories you can pay for better equipment but i thought the whole reason for the restriction on this type of 'pay for success' in the Bambino catagory was to even out the field.
Also, lf engines are being rebuilt after lets say 10 hours couldnt that turn a good c50 into a bad c50?
Forgive my ignorance, i really have zero experience with anything motorsport or mechanical.
