Re: Building a shifter kart

Can the weight be added anywhere or do they limit the locations?

Re: Building a shifter kart

It can be mounted anywhere pretty much. As long as it's secure and safety wired. I'll be throwing it all over to get my corner weights set

You don't think I will? That's the beauty of these, they really are hard to hurt.
i've broken pieces of my shoulder and spine in one. broken many ribs over 14 years of racing them across the nation. i've seen two fatalities and friends with broken backs and necks.


twisted a few chassis beyond recognition. hit someone in the side pod so hard once I broke both of my front brake rotors into a number of pieces. bent and broken rear axles. racing competitively, we would bend both 40 and 50 mm axles on a weekly basis. we would normally carry 5-10 different axles for replacement. they varied in hardness, thickness, and length for tuning purposes.


they are not to be messed with. anything from an 80cc shifter up is getting pretty darn fast.

when i was racing back in 07, i was significantly lighter. i would fluctuate between 152 and 158 lbs so i ran approx 25-30 lbs of weight depending on my weight at the time of the race. We had it down to a science with how much fuel to run so i could make weight at the end of the race.

I expereiented with fuel all of the kart. I ran it on the chassis, floor pan, and seat. after spending a lot of time in the seat (approx 15 hours a week for 14 years) and a lot of time on the scales, I found that mounting the weight as low as possible on the seat. Use thick seat mounting washers so you dont tear the weight off of the seat. Also, a word on seats, I ran Tillet fiberglass seats with the 1/4 padding on them for about 10 years. Then i finally went to a Ribtect carbon fiber seat and a ribtect rib protector. It was the most comfortable, supportive, and secure seat i had ever used.

Oh absolutely. These aren't toys. I mean they are but... You are right there is the potential to get hurt for sure. I only raced for about three years and in that amount of time I saw 2 broken thumbs, and one broken leg. I cracked a rib, but that was my fault. I didn't have a rib vest at the time. There was a motocross track right next to our kart track. I don't think I can remember one race day where there wasn't an ambulance at the motocross taking someone away.

I might have to seriously consider a ribtect seat. All the top guys were running them when I used to race. I remember being a little beat up after a race day and I'm not any younger now.

Weight is a huge factor. That was my biggest downfall when I raced is I didn't have decent scales so I'm sure my corner weights weren't ideal. I'm definitely going to take a more scientific approach this time around. Thanks for the input!

Well I kind of forgot about this thread. Here is an update. I got the kart all put together just in time to make the last practice day of the season. I mixed up my fuel and took a ball park guess at jetting and she fired right up!

After starting her up and getting some heat in the engine it was time to test her out. Unfortunately I found a gear box issue. My 6 speed conversion didn't work so well. I found out that Honda has two versions of these cases and transmissions. A wide and a narrow. I had a narrow trans in wide cases and it wouldn't stay in third. As pretty as it was since I wasn't going to go to the track without a third gear I decided to tear the whole kart down. I had a couple of crushed frame tubes from someone clamping an engine mount way too tight. I got that fixed and just need to get it on a chassis table to make sure the frame is straight and then new powder for the frame. I'll be tearing it up this spring!
Saweeet! Brad That kart looks great!
