I have some wooden dowel rods I scrounged. If I feel the urge, I use wood. I woulkd think a straw would be long enough to not fall in.
Remember to inspect closely around the plug for dirt & crud before pulling it. I found a stack of junk on mine once.Sand & road grit & grime had accumulated there. A flashlight & a few seconds is all it takes to avoid crap in the cylinder. I ride on an oil over sand road, near the house, maybe thats where it copmes from, I know I need to check, maybe you dont.
