+1 on Garth's recommendation, the longer hose gives the oil (in the blow by mist) time and surface area to separate and drain back to the crankcase. Gases go out and the oil drains back....Good catch Beano.

While I haven't fixed it yet, I came to the same conclusion, particularly with sustained hight revs.

Well that might explain it, with my pinched fuel line sustained high revs is currently limited. The new shoes go on the weekend and if the weather holds a long test ride with properly routed fuel line. Guess i will wrap a clean white paper shop towel loosely around the breather filter to see I get any signs of oil. The eye might miss tiny drops but the white will expose them.

Back to your original topic. Why don't the fuel lines have springs around them, given the tight space and heat and many a mention here about similar issues.

Here is an update, I chose to buy FP carbs from my buddy Frank for the meager sum of a $100 beer. I have been riding with FP carbs on a GF bike with limited success. I get about 100 miles before I get fuel starvation issues. It is like having a 100 mile range tank. I got the bits I needed from RPM to convert the carbs over to FG a few weeks ago but they sat due to a lack of motivation. My ride down to San Diego with 4 other FJowners really gave me motivation. Its like having a small bladder and having to stop every 100 miles because you have too.

I bagged and tagged my old carbs for parts. I rebuilt the FP carbs today to GF. I took my time and managed to do one carb at at time to avoid mixing parts and loosing where I am at any given time. I used the SST fastener kit as well to get rid of the F%$# Philips fasteners. I also fixed some minor issues while I had the bike opened up. Synced the carbs and took her for a short test ride. I already have 100 miles on the tank so all I need to do is some sustained freeway speeds to see if the carbs run low/dry under load. I ran at speed (70+, not telling how fast I really went) on the 210 for over 12 miles then back the same distance with no issues. That was good to get that far at that kind kind speed. I think I am back in the Kookaloo zone for now. So thanks to Randy for the parts and knowledge to make the conversion for my old ambulance. WCR here I come
