346xp 45cc saw

[Whiplash1]

Have the old edition here and still running strong with 140psi compression but found a ne346 oem top end kit for $136 and wondering if I'd notice the differnce in the extra 5cc? Both the old and the new will be run with a ported cylinder. Any input in appreciated.

Personally I'd not fix what ain't broke. You can probs get a whole 50cc 346 for not a lot more than that if you scratch about.

If your sure it'll fit a meteor kit might be worth a thought as they are good quality.
