Just got an arrow x2 kart with a 100j engine with clutch. Havent taken it out yet. Need all types of advice like what oil to premix ratios?? Tyre pressure? Anybody been to stony creek vic? General maintenance etc.
Also want something cheap to be able to see my lap times without spending $600
Cheers

20:1 we used to use motul 2t from a motorbike shop there is no kart shops near us. Go the mychron 4 cheap but still good.with our j I treated it like a lawnmower it won't die just keeps on reving.you will get plenty of practise out of it then weigh up the differences of cost between a rebuild or something more competitive a bit more zing the Ka100.
I would say 16:1 and a caster / synthetic caster based oil. Not sure if Shell M is still available, but that or Maxima 927.
For the lap timer, you want a magnetic pick up for lap times and a head temp sensor that mounts under the spark plug.Mychrons are easier to use (my opinion), but even an older Alfano will do want you want.Just get something that suits your budget, with the two sensors mentioned.
Yeah mate sounds good just why will I need a temp sensor for?
Head temperature will give you an indication of the carburetta tune. In a J you probably should be under 200 deg C.Would need to find some old data to check what we actually ran.
Almost any second had laptimer is likely to have a temp sensor as well anyway - just make sure it is head temp, which mounts under spark plug,.
I picked up an alfano ads gps for $250 new. Sometimes they pop up for this price.
Where abouts you get them from??
