it's not that bad of a job,just a lot of steps and having an extra body to lift the HEAVY seat off will save time. Also nice when lifting the fender pan off.
Before you start...order a 'cold coffee Mason jar filter' ! Recently saw here TEMU had them for $12 ? Amazon of course, prices vary. I got mine from TEMU for about $15 (?) years ago, Super fine cylinder of SS,fit PERFECT.
5-6 years ago a 'sliver of black plastic' got wedged in the exit spigot,so tank HAD to come out. I 'booked' 3 days for the job, summer, nice weather, no hurry.1 to get it out, 1 to clean, 1 to reinstall. Two guys, warm garage,good lights,great music ,it'd be a 4 hr job.
