Hi all, I thought my '99 ER-5 was vacuum-fed, since the petcock only has ON-PRI-RES, but when I pulled the (very cracked and brittle) line off the petcock, petrol went flying I bought some 3/16" (4.8mm) fuel line but this seems too small. I saw 6.5mm regular plastic tubing at SuperCheap, should I have bought that? (pics to come) Now I have a bucket of fuel with a red/ruddy haze at the bottom - would this indicate some tank rusting? (pic to come) It's always looked fine from the top filler cap. The wells around the plugs were full of junk-organic and otherwise but the first one looked ok to my untrained eye... (see pic) Lastly, it's always been very loud, clangy, and rumbly around 4.8-5.8k revs. Not sure if it's normal but is it worth checking valves, carbs, and cam chain tension? I have a manual but it would be my first time. I recently overhauled the front caliper without much issue, but the cam chain seems like it could be trickier.
