Probly have 7or8 of the multimeaters waiting to be opened up and a couple on my desk and one in every vehicle including the bikes . A cheap piece of crap but when you think your bike battery is weak you know in seconds , no guess work . When the battery in the meter gets weak enough that it won’t read I toss it and get a new one .
I never had a heat gun , I got torches to make all the heat I want . One year at Uncles his DR 350 wasn’t running right so we pulled the carb , at some point somebody had been working on it and the airfilter boot had been improperly installed and was letting a bit of dirt in that had clogged a air port in the intake horn , after curing the performance problum I started trying to reshape the boot to fit correctly , being cold rubber no way could I make things fit right . Roger said “ I got a heat gun , try that “ we warmed up the rubber fit it to the carb and clamped it and let it cool and everything fit perfect . Next day after I came home I went to hf and bought a heat gun . It gets much more use than I thought it would , specially in rebuilding hydraulics . Cylinder seals were always a bit of a pain to install , not any more , a little heat softens them up till they pop right in . I keep extras on the shelf with hf tools , when one craps out I open a new one just like the multi meters , a replacement battery cost more than a new tool .
