Why what would be wrong with these ones ¿
Where would I get a reasonably priced Athena onewrote on 20 May 2021, 15:01 last edited by Calum@oisin Why are you cheaping out on the heart of your motorcycle.
Firstly, tolerances. China aren't known for the QC's.
Are the bores correctly honed, are the ports chamferred.
Secondly 3BN is a larger bore requiring a shorting stroke.
Fitting a genuine 3BN barrel to your 3MB will result in the piston fouling the head. Which would be disastrous.
I got a brand new 170 Athena kit for under £400.
But Athena also do a 125.

@calum
Thanks I really appreciate it. If I get rebore would I have to get new piston and if so what sizewrote on 23 May 2021, 16:39 last edited by@oisin When you rebore you need a larger piston. The piston should be supplied at time of rebore to ensure tolerances are matched. The borer will advise what piston to go with.
Once you go to a certain bore size, the powervalve must be modifed to avoid fouling the piston.

Hey
I’m looking to get the bike up and running again for the summer and I’m wondering if anyone is selling a cylinder for a 2005 Dt125. Ideally with piston and pv, all good to go.
Thanks guys
