Hello everyone. My name is oscar, I'm from Spain.

I just want to introduce myself and my bike.

It is an nsr mc18 with swing and rear wheel of mc21, fork of gsx and front wheel 16.5 magnesium.

It a track day bike.

Actually I have 4 engines.
1 mc16
Mc18
Mc21
And nf5 1987.

Actually I use mc16 (while I rebuild my mc18) with mc18 barrels ported (similar than nf5 barrels), head modified and ktm 125 flat piston (I saw people using Rm but it is not same degrees (8 vs 10) so better to make it flat.

Actually I use 2x 38 PWK and NX5 exhaust.

I'm making 2 independent CDI programmable with 4 different curves for the nf5 ignition wheel.


I'm thinking about making a project. I saw tyga 300cc, I think it's just a normal nsr150cc adapted to the 250. So I got the idea of putting a set of malossi 180cc from nsr125cc to the 250 cases. What do you guys think about it? Did anyone tried it?
