im jonesin for more power. are there any nb/se50 stroker cranks? is there any way to adapt an sa50 crank to nb crankcase? i know the nb/se and dio motor share many parts...the variator being one, so do they have a similar crank?

stroker crank=more displacement and bmep=more power

The '94 - 02 crank is not interchangable with the earlier Elite. You might try one of the EU / UK scooter part sites to see if the parts are available there. It will not be an easy upgrade path.

yeah, i know it wont be easy, just wondering if it would be minor machining or if it just wont work at all....

don't quote me on this... but quite a while back i did see a Phongeer "PG" stroker crank for the 86-87 NB50 / SE50.
overseas, the '85-'87 Aero 50 is called a "Vision."
i know that the 85-87 Aeros look identical to the Vision in Europe.
you will rarely see performance parts listed for the Aero 50, but if you see parts listed for the Vision, you have a 99% chance of the parts working on your Aero's bottom end. Malossi has quite a few parts listed for the Vision on their site.
keep in mind that the '85 Aero had a TOTALLY different engine than the '86-'87 Aero - so i would assume that the Vision did as well too.
anyone correct me if i'm wrong.
later, jc

While were on the topic of strokers...To get things cleared up...theres NO stroker mods for a Spree right?....theres no PURCHASEABLE mods either right?

There are NO spree specific aftermarket parts. An adjustable timing aftermarket DIO CDI is a plug in.
Carbs are carbs, you could (in theory) bolt a tilly straight to the reed block and do away with the manifold.
With some modding a SE50 bore kit is suposed to fit(it bolts on but the pop up is -5mm) probably enough meat on the deck/first fin to shave it.
Front pulley can be modded for taller gearing, with a macine shop at your disposal a variator is possible(although nobody has done it yet).
You can port any motor.
Tuned pipes can be made or modded to fit.

hmmm so this means that sb50 shares the head stud pattern with nb/se50?
