still not sure what to do with my daughter, to move her up next year to cadet or keep her in Kid kart, was looking at a few cadet k80 there more affordable then the micro max and a nice in between from KID kart to micro max is a big jump, i tought the k80 would be a better option, keep earing alot of mix reviews, could you let me know your toughts those that run that class

I'd go K80, allot less complicated.

now got into reading about hpv seems easier to set up and decent price

That HPV/KPV is a great package not too expensive used and you'll have to mount a pipe. KT100 jr can muffler set up is good too with the new dry clutches. K80 has a Tilly and a pull starter. Honda Clone racing is cheap and getting big in some areas. If you're going to jump into the rotax world I'd do allot of research to find the real cost of maintenance and required upgrades, resale lose ect. Depends on what gets raced at your track and your future goals.

Hi Marc,

If looking for engine work.

Doug Fleming does as good a job as can be done on the K-80's.

Things went very well, im Green when it comes to that carb i had read alot before hand and we logged over 70 laps all with no hickups.

Daughter loved it only 3 months in kid kart to Cadet and at least on straight away we logged 11810 rpm letting off.

I have no balast so we are under weight wich made kart looser then should be.

One question is CHT temps were fine for her first time, high 300 low 400 but on Decel once in a awhile we saw 580-600cht but fraction of sec.. she was on off gas thru alot of corners, would that cause those Temps.

Thanks

Those temps are a glitsch, try separating the temp and tach leads as much as possible. possible intermittent open in temp sensor or internally in guage
