really digging the black plastics and compkart livery
That plus the dark blue frame and I went with a dark metallic gunmetal wrap on the floor tray it has really come together.
I’d like to source a black fuel tank. I think the older CRGs were a translucent grey.
This bad boy probably gets sold tomorrow, unfortunately got no time for it. House, girlfriend and the classic kart takes all my time. But it doesn’t go far so I could still see it.
Only material stuff, and if I plan to run Kz I will buy more up to date stuff. But the 10c has never failed me, still outpace R1 stuffs at certain tracks😄

I recoated my compkart to try to match the blue as closely as possible. I think it looks killer with the black plastics. BUT i run a Harden Motorsports Group livery.
I did a full teardown of my 2025 praga dragon, 3 races old to check for worn parts and a nice clean took 5 hr and also did 3 engine rebuilds for customer!

Neat! I’m curious what your objective was with this…clean off carbon? Create a particular surface finish? Alter dimensions? 
Also how are you liking the LKE?

Matching the port to the header shape?

The engine is absolutely awesome and I think is a notch above the R2. This particular one comes from the Factory in Sicily, then Barcelona to one of the best independent,factory-backed developers then to me in CA. So it’s already 99% perfect as a top tune/Factory special. At 6hrs run time, as I go through a regular piston change, I try to take care of the 1% left…since I have to de-carbon the exhaust port, I do a final smoothening to match port to header/polishing/surface finishing job. Same with the head insert, squish and few other things, but the baseline is already there and there is very little to do.
A friend of mine took the sister engine (in Supernats config) to a (major) US tuner and he was absolutely impressed. I think we got all there is to get out of it, we are now working on tradeoffs…like a bottom-end cylinder, a max power and a high-revving one. In parallel, reeds and head inserts are the other big variable, since fuels are completely different in US so we are trying to explore a little. The engine design comes from Roland Holzner (Maxter, Modena, now LKE) so the thing is a little bit of an artwork. (Maybe I’m biased)

Not a kart, but got my mountain bike out now that the weather is finally starting to break and it’s finally under 90 in the morning

Spent the day giving my kart a much needed deep clean and a general freshening up, added some weights for my next race and ripped the crusty floortray stickers off, Still have a bit of work to do but that will come in the next week or two as i chip away at it

Looked at my data and realized my engine isn’t as fast at 140f water temp as it is at 130f. I noticed the radiator curtain covers about 10-15% of the core even when fully open, so I took it off and make this little scoop out of lexan. Heated and bent it in the vice, trimmed and decorated with some blue number backing that happened to match the rad mount and cap fairly well. Also planning to make a guard screen out of some stainless 1/4" spacing chicken wire.

It always surprises me how rarely you’ll find ducting on kart radiators. Maybe you could argue that it’s an aero problem… but then again you could use a smaller radiator too… possibly.
The guard will reduce the airflow quite a bit, it’ll be interesting to see if you end up with same temps or lower ones.
I tested this exact guard design back to back on my old superpro shifter, zero difference in temp on a roasting fl summer day.
I think the positive cooling effect of the induced turbulence likely offsets the velocity drop. We will see how it behaves. On the KZ I took the curtain off, and added the scoop/guard all at once so I won’t be able to determine exactly what each change made, but overall I expect better cooling with less radiator damage. Old shifter pics for reference.
Edit: I just spoke to a friend who Was a long time IMSA crew chief, and now owns a team, He said they tested it on the cars and as long as the grid is bigger than 3/16 and is around an inch away from the radiator or more it has negligible effect. Any smaller than 3/16 and you can see a negative effect on cooling
On the KZ and on the old super pro machine, the grid is a quarter inch. The new guard I just made for the KZ it is about 2 inches away from the radiator so that should help even further

Yeah that’s what I had on my KZs…
