Does NT50 Melody mini fit bigbore kits with NQ50 Spree engine?

Post by IplayBanjo »

Hi from Denmark

Yeah like the topic starter. I want to build a bigbore kit on my Honda Melody MIni (NT50) and cant find any parts for it. My question is, does i t fit parts with the Honda Spree NQ50 ? :coolcruise: :coolcruise:

UK models ND50 and NP50 do not have big bore kits and all you can do is buy an oversize piston and bore out the barrel to get something like an 8cc increase in power.

I did try a barrel from an 80's Vision (NE50) but it didn't match the crank case.

You could try ordering base gaskets to see what might fit or just stick a Dio in it and have the job done.

Just had a look on CMSNL and the Danish NT50 has a different barrel to the english one (Danish one not pictured on CMSNL).

If you post a picture of the engine and the year you might be lucky for BBK and might be able to get something like this (note angled/ side exhaust stub):

correct me if im wrong but that's just a spree with different fairings. kicker points forward like a spree, no variator like a spree. that's a non USM spree...
if all this is correct, yes a spree bbk will fit

I wouldn't bet on it.
You'd need to try seeing if a base gasket fits and go from there.

In the UK the Melody Deluxe, Deluxe 2 and Mini have different heads and different shaped pistons amongst many other subtle changes.
