There are no local G4 drivers around this track, they just resealed it for the second time so everyones setup is up in the air right now until the track settles down but there are a couple of wicked bumps (one putting ron atomic into a flat spin going down the straight, while going straight amazingly enough) and with enough rubber the traction gets decent, previously to the point of traction rolling but I haven't seen it anywhere near where it was last year yet.

Hi Gansei,

I have run the CRF engine almost all year and I find it very good. The bearings will suffer if you have poor quality fuel, but with good quality fuel (better quality oil), the bearings are very good. CRF does recommend changing them after every 10 hours though. The good thing is that the conrod very rarely needs replacing. The piston and sleeve are also very durable as long as you get everything right.

One of the best methods for tuning this engine is to start with 1.5 turns out on the middle needle and then adjust the low end needle to make 47.9mm (see the team orion site for a diagram). This is an excellent starting point and I always start at this point for racing. Adjust the top end needle for maximum power from there. If you want more bottom end, don't adjust the needle, just adjust the clutch parts.

I have even run this engine after it swallowed a plug element and it built up enough carbon deposit to seal the piston again.

The engine will not have the same bottom end power you were used to with the modified TZ engines, but you can compensate with clutch tuning and very slight bottom end needle settings.

Hope this helps.

Sorry I don't run a g4s and I don't think I've even seen one at the track before and certainly not since they've resurfaced it. The track is mostly 180 turns with short straights, one sweeper at the end of a 160-170' straight that is fairly tight. There are a few large bumps, but mostly smooth and medium traction.

At least everyone is in the dark since the new sealer was laid down. Ron Atomic was out testing last weekend and was at least a full second slower than he was on the previous track and was changing his setup considerably.

These settings are for UFO1 as I never tried UFO2.

I ran the red clutch parts, .5 or .6 gap(depending on the track and grip) and .3mm preload with the modified clutch nut (filing down the lip on the nut so it's flat.
