What would be the effects of to much left side weight too determine if you needed to reduce your % ?

Re: Too much Left side weight?

4 wheel drift, no side bite equals to much left side. about 54-56% is a good middle baseline probably for most tracks.

Re: Too much Left side weight?

For me the kart goes flat when I've got more left than I can effectively transfer. However, I rarely fix the problem with less left; most often I try to add bite or something like that.

Re: Too much Left side weight?

Can we say as traction decreases so does LS%

Dead on 100% what we've seen. With the newer karts that prefer the LS weight, we'd prefer to create more transfer through bite in the tires than to pull LS off the kart.

Re: Too much Left side weight?

54-56% will get you lapped on most SE tracks.

No, you can't say as traction decreases so does LS%. You can create grip with LS tires just as well as RS tires. The key here is to get the kart rotating well on its own (stagger, geometry and grip).

If you're counting on load transfer to create rotation then yes as traction decreases so does leftside. HOWEVER, that is not the fast way around the racetrack.

Re: Too much Left side weight?

54-56 was just a starting point suggestion.

Re: Too much Left side weight?

Thanks for all info. I know about the way the manual's read and people say as far as lite,med,hvy.& super hvy. what there percentages should be "BUT" they only go by weight. You can have a guy 5'6 205lbs. running super hvy. or like me 6'2 230lbs running super hvy. the weight is going to transfer a bit different in my opinion. But was wondering what to look for to determine if you have to much. That way your not thinking it's a cross,cam,tire issue. Thanks for any further info.

Re: Too much Left side weight?

IMHO, Available bite in the track will determine the amount of ls weight that should be run. In the south were there is a lot of bite in most tracks they run anywhere from 58-60+ leftside weight. In the north where most not all track are moist slick or dry slick you usually see lwer leftside weight because of lower available bite to transfer weight. In my area you rarely see a fast kart with more than 57 %.

Re: Too much Left side weight?

look at the tire wear,,, if out side tires wear faster than inside,, you don't have enough left side weight,,,,, if you start out real good early in a run and you slow down, you may not have enough left side,, we race down here in the south,,,, but all track are not bite up like some think up north,,, several track you will have to run a Vega in the teens to be fast,,, but most track do require a tire duro in the 45 to 60 range..........

Re: Too much Left side weight?

I dont race dirt but on pavement when i see a kart with too much left side weight its usually flat from apex out or has a 4 wheel drift.

I start off around 57% in sr champ karts. pavement

Animals seem to like more ls then flatheads

Re: Too much Left side weight?

look for a dead kart...(handles fine but slow off) or 4 wheel drift. look at banking, track grip, and the track shape/size when choosing a ls weight

Re: Too much Left side weight?

If you know the tires are close for the conditions, it'll usually fly for about 3 laps and then start skating on you. I know it's sounds backwards and was biting me for awhile when I wanted to keep taking left out and it never got better.

Basically, the kart starts out good and then the RS will start giving up/releasing. It needs the LS tires to help make grip.
