I did an oil change on my Prima 150 today, and this went remarkably easily thanks to a few handy items which I thought I'd share.
I have no handy stand and if you use the centrestand, this gets in the way of drainage. I used a 100 x 100 block of wood under the right side of the stand and and a 50mm thick block under the side stand. This holds the bike vertical and steady.
Next up was a 150mm "wobble" extension bar for the 24mm socket; this lets you unscrew the oil drain with ease, working around the exhaust.
My last win for the day was a cheap oil pump to transfer the new oil into the filler. This cost me about USD15 at my local auto parts store, and allowed a completely mess free refill of the bike (as in not one drip spilled!). I can recommend this item, looks like it will also be ideal for refilling the final drive too.
