Hi, I recently purchased a dt125 sm 2005 and I thought I shall rebuild her. Ordered a wossner piston kit, and I came to realise it wouldnt fit, as the old piston is .25 oversize!!
So with the old piston being in reasonable condition I put it back together and now I'm back on the bike (it now runs and starts better but it doesn't tick over without the choke on and bogs down before the power band??????)
A: does having an oversize piston and barrel to suit = more power?
B: would it be better/easier to go back to standard barrel and piston size?
Thanks for any help in advance!! Just trying to learn
