Close to the end of building my version of the spidercarts tarantula. I have the full chassis done (no body panels or floor yet) and all the mechanical is also done. At the point where I am driving it to make sure it all works good and like I want. Just finished with my final upgrade and that is a juggernaut on my basically brand new TC despite one or two run hours. The first time I used the whole stock TC and it worked fairly well just did not let the predator 212 rev past 4K so I put a juggernaut on to help that issue and also put a new green spring in instead of the stock red spring in the TC also. Took it out for a spin and does not go as fast as the stock TC did. Why is this? Gets to about 5500rpm on flat ground so it revs like I want it to. For reference I was hitting 45mph before now about 38mph using the same app.
Also noticed that when I whip the kart around and do a donut every now and then the engine will all the sudden loose all load and rev out and the tires will stop spinning. When I look back the TQ where I put the new spring in is smoking, what is causing this?
One more issue I have is oil coming out of the valve cover breather. I think this is my fault as I filled it about 20 ounces and not the recommended 16 ounces. Am I correct? I’m planning on just running it until it hopefully stops as it gets back down to the correct level.
The last question I have is what is a safe rpm for me to rev to considering the connecting rod is stock? s of now I’m keeping it under 5500 as I have a digital tac to help me keep track.
Predator 212 mods-
• Governor removed
• Low oil sensor and sensor inside engine removed
• Performance air intake
• Bigger carb jet
• Custom exhaust, no restriction
• Arc Billet flywheel
• 22lb valve springs
• 30 series TQ with Juggernaut and Green Spring
Go Kart-
60 feet of 1/8 wall 1x1 tube so far
18x10 in rear, 18x6.5 in front
6:1 ratio
I weigh 160 I’m guessing kart weighs 200 as it sits
Yes the engine is at a pretty large tilt but it somewhat flattens when I sit in it
