Jack placement for lifting front end

Does any one lift front end by jacking under black plastic vents .I was thinking of a fork paddock lift like they use on sport bikes. Any other ideas would be greatly appreciated

I've rested the bike on some wooden blocks there while the front forks were off. As long as the bike is still supported by the centre stand theres little weight at that point.

I use a small trolley jack. I place the lifting cup under the frame cross member just behind the tupperware. I can then make minor adjustments to the amount of front end height as needed. For safety use a small wood
block between the cup and front axle of the jack.

Here is a close up using a trolley jack. Like Kurt I use a piece of wood and a foam pad. Raise it slowly

Following advice from here I did the same when jacking-up the front of my Silverwing although I used a scissor-jack, not a trolley-jack.
The wood spreads the load, especially since the platform on top of my jack is not very big/wide.

I have a scissors jack that I will use with block of wood thanx to all
