craigbulmer · Guru

fairrrr enough

you topend buggered?

RudiRulez · DTR Senior Member

not yet but everyone recommends tidying up the top end at about 10k miles and im at 7k reckon i will hit 10 sometime during the summer so may aswell start looking for bargain parts now.

craigbulmer · Guru

fair point.
but when you change the piston, its best to rebore aswell, is it an oversize piston?

is a hole kit?

RudiRulez · DTR Senior Member

just piston, was gonna use gudgeon from the old one and just buy small end bearing, circlips and rings seperate.

Also, didnt think i could rebore a DT was told they were nikosil plated?

nope not nikosil plated.
(well truth be told, no idea what its made of)

mines just had its second rebore, first at 11k, second at 14.7k (dont ask i dunno whats gone wrong)
just had it done

btw, i wouldnt get to worried about rebuilding so soon, elements DT125RE is on like 28k on original piston.)
wolls bike is on 15k no rebuilds.

if it starts running bad or rattles bad then rebuild it ;)

my first rebuild on 18K. still on my second at 4K later. long as the bores are the same, cant see aproblem using a tdr piston. yup and craig is right, not nikosealed.. think its a steel liner., daf not cast liner
