PPIR is gonna be back as well? That’s awesome. At last year’s SOLO nationals a 125 shifter set the fastest time of the event. Clearly the handling and power to weight ratio of a kart is a force for big cars to recognize. Greg’s a hell of a driver, but to do that with only 60ccs is nothing short of amazing. Although, assuming that was what? 3 or 4 years ago? He probably only weighed like 70lbs at the time, huh? 😆
Hah!
Yeah, it would have been around 2000 or 2001 when we last raced at Second Creek. I was in 80cc at the time, and we were running faster than the Formula Fords could!
I think a 125 shifter held the track record out there for awhile, until Paul Tracy showed up in his Champ Car for a test day.60cc engines have not been used regularly in karting for the last 4 years or so. A modified KX-60 would have never been legal to race.
So…. if it was bolted to a kart, I think you might have a shot at selling it… but I’m guessing it’s fairly unlikely that just the engine alone will sell, particularly since it’s still set up in dirt bike trim (kickstarter still attached, etc.)
But hey, throw it up for sale and see what happens.Franco, we charge $45 an hour for labor. Generally just going over a kart and checking it out would take about an hour – and then if we’re fixing anything, it will obviously take longer. I do not know if Kartworks does service work, or just retail sales, but you could certainly call and ask them.

The hoses…you need to replace them. I’m guessing they hit the exhaust pipe or something?
Actually, no. Those hoses are vent hoses, they are supposed to have holes in them. You’ll see something of that sort on all Keihin and Dellorto carbs.
As for the brakes, I can’t really say without seeing them in person, but my recommendation would be to drain all the fluid and clean everything as Troy suggests. Then fill with new fluid and try bleeding them. If you’re still having issues, chances are the seals in the calipers and/or master cylinders need to be replaced. SKM brakes (SKM is the brand name of one of the larger Italian component and chassis manufacturers, by the way) are standard stuff; IMI may have the rebuild kits in stock, or we can definitely order them in.

The 3rd pic down is under the seat but the rest of them are in front under gas tank
Yeah, exactly. The skinniest area of the chassis, under the gas tank, is what I’m referring to as the “waist” and is the most important area of the frame. The flex characteristics in the waist are crucial to getting the kart to handle well, and when it’s flat spotted that much, the flex is definitely thrown off.
I would pretty much consider that chassis toast. Flat spot the size of a penny in the waist is definitely not good.

Hi Ken,
I think the fact that you had 5 race weekends on the top end is what caused it to fail.
3 weekends at the most on a top end is what I would recommend, I’m guessing it’s a 2 day weekend.Rob
The stock Honda can run much, much longer than three weekends on a top end without failure if everything is installed correctly.
A built Honda, you’re right, 3 weekends is pushing it.@Rich Vito wrote:
Can I connect to the rear bolt hole?
Not recommended, because if weight is transferred to a point behind the rear axle, it will tend to unweight the front tires. Imagine someone jumping on your rear bumper – same thing.
@Rich Vito wrote:
On the engine side can I connect to the inner cassette, which I run loose?
Again, not recommended. Trying to transfer weight through a point that is essentially floating is inefficient at best. I think it would also defeat the purpose of running it loose, as the strut would hold the cassette in place… and the whole idea behind running it loose is to allow it to float around a little. I don’t know anyone that’s tried this though, so I guess you could be the guinea pig…

Can I connect two struts in the same bolt?
Sure, I don’t see why not.
Mark,
There’s a bunch of different series in CO.
The Colorado Junior Karting Club (CJKC) that Rick mentioned is basically a regional series. It visits 4 out of the 5 tracks in CO, plus a temporary circuit in the parking lot of the Littleton Home depot, and runs the Comer K80 engine.
The Colorado Sprint Championships (CSC) is also a regional series and visits 3 tracks. The difference is the CSC runs classes for all ages whereas the CJKC is for kids only. The CSC uses the Rotax MiniMax or Honda engines.
CRE Motorsports, near Colorado Springs, would be the closest track to you. They have a series that runs at CRE only. You can run either the Comer K80 or the Rotax MiniMax there.
The Track at Centennial and IMI do a “club series” which bounces between the two tracks. You can run the Rotax MiniMax or the Honda engine packages there.
So, there’s lots of choices. Like Greg said, give us a call at the shop and we’d be happy to go into detail on any questions you might have. 1-800-608-3457
For what it’s worth, I recently heard about a small track in Albuquerque that’s apparently running races now. I don’t remember the name of it, but it might be worth looking into.
Drew,
Maranello is built by CRG, and uses all the same components as CRGs do (just anodized a different color). We are a CRG dealer and can get any of the parts to fit Maranello. CRG parts unfortunately are very expensive. Some of our own brand components will fit (axles, tie-rods, others), but some parts (front stub axles, brakes, hubs, others) are unique to CRG.
Chains and other engine-related parts are not unique to chassis brand and are readily available.
Slop in the steering wheel is not normal, but can usually be fixed by something as simple as tightening the bolt where the steering hub attaches to the steering column.
Most people just remove the rear wheels and sidepods. The sidepods are one or two bolts each, and you can remove the wheel & hub assembly together, which is only one bolt on each side. It’s not as difficult as it seems.
I have never gathered sector time data. What I have done is used an E-Box (with the lateral accelerometer and speed sensors) combined with the AIM software to break the track down into splits based on each individual corner. I think this is more useful than just 3 time splits, but you have to buy an E-Box, which aren’t cheap. Theoretical best lap is extremely valuable.
