Building a shifter kart

cnckart is an old sn that I have had for years. It comes from when I used to race shifter karts. Shifter karts are an absolute blast! But with any motorsport it isn't a cheap one. It's no where near the level of cars on the money scale, but it isn't a poor mans sport. I had to give it up about 7 yers ago due to being a poor man I now have the means to get back into it. I won't race often because that is where it takes the money to compete. I just have missed the sport and want to go turn laps on practice days.

If you aren't familiar with shifter karts they use a honda cr125 dirt bike engine. This gives them a sequential 6 speed trans. They make about 35 horsepower, but when the driver and kart together only weigh 385 lbs. that's a pretty good power to weight ratio. They have 4 wheel hydraulic disk brakes and are liquid cooled. They will do 0-60 in about 3.5 seconds, and can pull upwards of 3 g's through the turns. On with the build!

I found a screaming deal on a used, but low time and clean 2001 PTK Monterey chassis. It's a pretty complete roller.

I bought a used bottom end and transmission off ebay. Again I was frugal as I plan on rebuilding it, and modifying it within the rules.

The engine had thrown a chain at some point in time. The cases were good, but had some slight damage. After tearing it down i had to do a little welding and machining.

And here it is all torn down. I have 90% of the parts needed to put it back together.

This engine should be done within a couple of weeks! I will post pictures of the build as I progress. I am really looking forward to this!

Re: Building a shifter kart

I've always wanted to do something like this. Last summer my wife started tracking her BMW and it is really expensive. Maybe someday I can play around too. Looking forward to seeing it all come together!

As am I! This is totally a budget build. I plan on having a track worthy kart for about $2000 bucks. Not too bad for that level of performance. Maybe I'll bring it to summit!

Make sure you put some knobbies on it! You know... you might have just found a way to reuse the FJ's stock tires when people upgrade.

Do show him. If you are patient you can put together a kart pretty cheap.

Re: Building a shifter kart

A Lap around Laguna Seca. This isn't me obviously, but this 125 shifter kart is only about 30 seconds slower than an Indy car on the same course. Keep in mind this is a car track, not a Kart track. I can't imagine taking the cork screw in a shifter. Lap Around Laguna Seca Raceway - CR125 - Stock Moto Shifter Kart on Vimeo

Re: Building a shifter kart

Those Busa karts are insane! The only place you could really use it would be place like Laguna. One of my favorite tracks as well. Once the kart is done I'll get a go pro, Can't put a whole camera system on a kart.

Re: Building a shifter kart

I hear ya. Seca is just so different from other places. The elevation change, the scenery and the turns. Some parts, if you got the line right, you can fly through without slowing at all. Other parts will really bit you if you are a little careless. It was fun watching that video!
