I am getting ready to install frame sliders and my Hama exhaust. In another post I saw I might have to lift the engine a little for the frame slider install, or rather support the engine. At pepboys they have a engine jack for real cheap and I was thinking about grabbing one but I have a couple questions. First, where do we lift our bikes when we want to? Second, will the jack get in the way of the exhaust install, so for the slider install I should just look at renting something? Third, in the future will I have a need to do this?
