@Stevie-Wonder The RX/SX/MX just have better bits, immediately I can see that the shock is better, the swinging arm is better and probably the engine might be less restrictive.
I've ordered an RX swinging arm, SX shock for it. New piston, rings and gaskets. New plug, two stroke oil and gearbox oil. Full Arrow system, 28mm Flat Slide and VForce3 reed system for it. Would benefit from a new 28mm inlet as this one is starting to perish.
I need to raise the bike a few mm as it's a bit short for me, company in Germany make a jack up kit, but appears they won't ship to the UK, so I will probably just make my own jack up kit.
I'll whip the clutch cover off and make sure it's not going to shred the balancer shaft gears. There is a heavy rattling sound under load, that needs looking at.
I'll take off a few pieces run them through my shot blasting cabinet and get them looking pucker.
Plan is to thrash it on some green lanes, keep an eye out for brand new genuine panels and get it all refurbished in the future. But for now, I'm enjoying the dutty look as all my other bikes are pristine.
