    Good update Big Smile  The difference you get with a few choice investments is certainly worthwhile.  Looking forward to hearing more...

    Caroanbill:

    Hooo - weee! Collected my PX150 ("Blackie") on Saturday mornng and spent much of the day zipping about, mostly two-up.

    It's transformed!

    Motor

    The SITO Plus / re-jet / hotter plug / freer intake has made a marked improvement to midrange urge, without losing the low-end urge that makes teh PX so tractable.  It would pull through much more quickly to 80kmh two-up on level ground - previously it would lose urge from 70kmh, solo.  Hills are still a big ask above 70kmh two up - but I didn't expect a miracle and I don't really use the PX for fast two up riding ... have the GTS for that (around town).  I feel I've still got the PX character I like, and now even more of it.

    Ride 

    Tyres first. The nice surprise is that the SL26 3.5s are just fine. A reasonable amount of spirited riding saw my "chicken strips" down to about 1cm each side, whereas on the S83s I was skipping on the edge of the tread. Of course, I wasn't about to test the edge of the envelope with Ms Delectable aboard! I should get right to the edge of the SL26s with a bt of solo fun.  More to the point, the stiffer sidewalls and even 'feel' of a good tubeless tyre makes the PX feel more planted to road - it's lost the jittery feel of the tubed S83s. 

    Rear Bitubo shock plus new bushing (firmer - think it's urethane but not 100% sure) has made the back end both more planted and more compliant.  The PX has lost a lot of the "hinge in the middle" feel, and it tracks a lot more predictably through corners where it used to wallow.

    Sound

    Nice and crisp!  The Sito Plus (plus the better intake flow) has a bit more snap / bite on overrun, and noticeably louder but still not offensive.  Well, It's a lot quieter than the Lammie series II I was riding with!

     

     

    thats your best post yet Big Smile

    What plug did you put in as mine seems to struggle in higher rev range when accelerating hard.  Also,  did you drill the air filter?
