    Fizzers... Painful at the best of times to tune up haha.
    Best of luck - I still haven't figured mine out sufficiently to actually give useful advice other than change one thing at a time and incrementally see how it reacts.

    That being said it's the most rediculously temperamental setup around

    I'll take it for another spin and see what it does. I'll try lowering the idle before pulling the carbies off again... that's a royal pain. See if it holds and the richness keeps it going. I just want to get the RW done so I can have it on the road legally, all the fine tuning can come in due course, at the moment it's a bit risky riding it around unregistered - cops passed me yesterday so I escaped by the skin of my teeth heh

    So I took it for a run, it just feels like it's not clean through the rev range and it ran pretty average. Rideable but I'm not satisfied. So I attempted to "tune" the pilots while it was warm, you can wind them in until the engine starts to cut out but winding them out I can never seem to find the spot that the rpm "changes". It's just like it winds endlessly with no difference until the pilot comes out. Comparing to the 250, the 250 is definitely "cleaner" even though it struggles on the top end. With the OEM exhaust the sound is annoying, it sounds like it comes from the front of the engine and is a bit hollow... the aftermarket exhaust is 10 times better.

    I think I have to reset the pilots to stock and start again, the other thing I noticed is that turning the idle knob seems really really hard. Don't know why, you can turn it but it's an effort. The 250 is really easy to turn in both directions.

    Try running some sewing machine oil down the idle adjuster cable.
    I found with tuning my 250, it run's the best when the mixture screw's just start to lower the idle speed (2 turn's out)

    I put it back to stock pilots 2.5 turns out and she's much better. @MashtX gave some good advice and suggested it was probably tuned for the aftermarket exhaust and it would work better around stock with the OEM one... that was a good call.

    Had a good 15 minutes on it and I reckon it will get over the line now, I just need to fix the leaky sump plug which I haven't done because I couldn't be bothered draining the oil after messing with carbies for the past couple of hours!

    What are the main things they look at there in Mexico for a new registration?

    The same sort of stuff Ese, fluid leaks, brake peformance, disc thickness, brake lights/indicators, general rideability, tyres/tread, headlights, fairings are secured properly etc. They are making it harder for aftermarket mufflers now that need photos of baffles inside them and also need to be independently noise tested to meet the 96 dB ADR. If I hadn't borrowed @MashtX 's OEM exhaust I believe I would have run into that issue as well, mine runs with a Macrae exhaust (wherever that came from, might replace it in due course).

    Good work. They're still very easy going on the UK when it comes to bike noise. As long as it has an exhaust then the majority of testers don't care how it sounds!

    I also used the label maker at work to make a "noise" sticker for the frame... a direct copy of Alex's one on his 400 that is a bit more *cough* genuine.

    I do need a better after market exhaust though, Alex has a black widow and it sounds really nice. Suppose once I move on the 250's I'll spend a bit more money on the 400.

    I need to look at the throttle cables though, the throttle is really "heavy". It pulls back and forward OK but it requires more force to move it than my other bikes.
