Hi, photos of the 4FU barrel with powervalve fitted, you can see the bore is scored
so will need replating or reboring. Just make me an offer if any good to you.

@2stroketerry what’s top speed you had out of your dt with the 170 kit on ?? Coz A few people saying there no good get a 4fu00 barrel and head ??
-
@sprintall84 It's not necessary speed you benefit from, but more torque. So gear it appropriately you should be fine.
As a general whole, the Athena kit isn't brilliant. A 3MB00SP Barrel is what you want. But the price for those is astronomical.
4FU is a decent barrel which is plated rather than steel liner. This benefits from better heat transfer. But draws back from expensive repairs. Ultimately the DT is limited.
A decent spec'd Athena 170 should top out at 100mph. Plenty for a 125.

Here is my ported 170 athena when first fitted it using standard gearing and went off the clock. Fitted an Athena exhaust and a 34mm polini carb with top of air box cut out to it after this video, did 110mph with an 18t front sprocket but really scary on nobbly tyres,lol
