How to Rebuild a Derbi Start V Engine - J's Garage

In this video I rebuild my daily driver Derbi Variant Revolution with the Start V (Start 5) engine.

I broke the transmission input shaft the other day playing with stuff so it had to be completely torn down to fix, so I rebuilt a spare I had in the shop.

I take the engine down using less than ideal methods because I am missing my crank puller, but there are some good tips there if you are stuck in a similar situation.

These are the bearings and seals I could get numbers off of.

Crank = 6204 x2 (20x47x14) I would use c3
Seals = 20x35x7 and 20x30x7
Output shaft = 6203 (17x40x12)
Seal = 17x35x7

If anyone has any of the other bearing id's let me know in the comments!
