Pine -sol, purple stuff and Castrol Super clean all work really well, I haven't tried it but LA Awesome cleaner undiluted would probably work well also.
Replaced the oil lines, I use Tygon weedeater fuel line for oil lines, they are a little thicker on the wall size of the tubing , I resuse the stock clamps instead of using zip ties mostly because I have never seen an oil line come off of one with a stock style clamp on it, like I said the lines are slightly bigger , to compensate I use a center punch and a hammer to open the clamps up slightly.
Just place the clamp and centerpunch over any piece of metal that has a slightly smaller hole than the clamp and give it a tap, reverse the clamp and do it again, you can see in that first pic the difference between one that hasn't been enlarged and one that has .
When you put the clamps back on I use end nippers to retighten the clamps, you just pinch the ears on the clamps and you are done, the top hose is next to impossible to get to the clamp on so on those I remove the banjo bolt and fitting from the pump. put the hose on retighten the clamp then put it back on the pump.
The oil lines are done, the carb is back on, gas is back in the tank and the system is primed, to prime it I leave the return line loose then blow pressure into it , when you see gas coming out the return line on the carb it is primed and ready to fire up.
Add $3.00 for fuel line and $16.00 for fuel and another 30 minutes on the clock , I decided to leave the fuel in the 4 tec and go run it to check it out further, it has current regs on it and it just might be my rider for the rest of the year.
Headed out to the other shop now to remove the impeller and repair it , as soon as the pump is back on it , the silicone is cured , it is fired up and on a decent trailer it will be ready to be water tested. After that all that is left is cosmetic work
