    I'll be in masterton. Flatmate will be home so you can still stay at mine if you want.

    well maybe true at higher speeds, I noticed a huge difference going from a 60 to a 70 profile front on the NC30. It now "tips" in heaps faster and feels a little more planted through the turns, nearly fell off the thing when the tire was first put on as I threw my normal amount of body language in for a turn and was then having to pick it up before the corner.

    Ok now we are getting into the difference in terms of discription.
    Yes it will lean over faster i agree, because the tyre is taller you need to lean it more to get the bike to the same lean angle (i am talking about the length of the arc your body travels from vertical to leant over, not lean angle here). No it will not turn in faster because of the more leaning for the same angle but it will definitly affect the way it feels. If a taller tyre front helped you try to raise the front end a little by pushing the front forks down thru the tripple clamps by 5mm (assuming they are not right down yet) or add a little preload in the front.
    I am also assuming you understand that the difference between a NEW tyre and a wornout one is huge even if it is the same size and make. A worn one slows steering and makes it feel heavy.
    Fiddle away man its how you find out what works. Do not be afraid to play with the knobs on your forks and shock. Have a twiddle and go for a ride. Note down what has changed in the way the bike behaves and fiddle again. Repeat until it feels great.

    I wish it was that easy R1madness. I can happily adjust my rear shock, but my fronts I can't. What do you mean by dropping the front forks?

    Ok. Have a look at the top tripple clamp. Is the top of the forks poking thru or are they flush with the top of the tripple clamp? If they are pokiing thru and you want to have a little play then you need to support the bike so the front wheel is just off the ground and loosen off the bolts that hold the forks into the tripple clamps as well as the ones that hold the handle bars to the forks. Now carefully push the forks down until they are level with the top of the tripple clamp. You may need to twist them as you push. Then tighten up everything and go for a ride. How does that feel now?
    When was the last time you had your fork oil changed? You can change the whole feel of the bike by changing the fork oil viscosity. In the days before adjustable forks we used to combine different weights of oil to change the damping effect and add some washers to the spring to change spring preload. Thank god for fiddly knobs and aftermarket spring suppliers.

    Lol, yep, the oil was changed in both forks about 3 months ago. I put them flush with the thriple clamp. Maybe a bit of a play is in order aye.

    Sounds like you have it pretty well sorted actually. Is there something in particular you want your bike to be able to do better?

    Like I said earlier, the handeling just feels heavier compared to a CBR250RR I took for a spin a while ago.

    Now we are getting to it.
    Do you mean heavy to turn in? Heavy to pick up after the corner? Needs a lot of pressure on the bars to keep it turned in?
    All will be affected by a change in tyre brands/compounds and air pressures. By the way what tyre pressures are you running?

    I always used 32psi front and rear, on my rr with gpr70s, and this always worked good as a guide.

    You still havnt posted what tire you now have on the bike (make and size)
    The contents of this post are my opinion and may not be subjected to any form of reality
    It means I'm not an authority or a teacher, and may not have any experience so take things with a pinch of salt (a.k.a bullshit) rather than fact

    If the tyre has been squared off, it makes the handling real heavy/shit. But your tyre is pretty good - it didn't seem that bad when I was on it. The manual recommends 110/70 - R17 for the MC22.
