[k14]

Well the fact of the matter is that I have talked to chris about it and to get it working well again you would need to pay more than $2000. So stfu.

[aff-man]

yip there are a few problems i can attest to it

[shandawg]

Anyone want to enlighten me a bit more?

Tossing up whether to bin the motor and start fresh, or do the work on it.

[aff-man]

Have you got it assessed it might just be a gasket problem

[shandawg]

Nah not yet, hopefully something small like that

Exams coming up real soon, can't afford to worry about it yet,

Still a cheap zxr even if I sell it in bits
