    Totally interested in what kind of gains you get. Looks easier if I send my motor to AF1 for the upgrade.

    For sure. This motor had been run 70 tkm so it needed to be taken apart completely to see what is going on inside. As a result the crank and balancer bushings were replaced, the gearbox got less worn gears and oil pump got new gears to name the most important. The 50 tkm engine I have in the frame now will be left as a spare engine. If you have a fresher engine or feel daring otherwise you may just replace the barrels and get the Gen2 heads/ ported Gen1 heads. The 1060 kit is waist of money with the standard twin plug heads, pretty much Gabro's words.

    A "quick" tune would be:

    Collector mod/ 2-2 exhaust + chip
    Timing the cams. Importante.
    Open airbox, like Jolly's carbon (not completely necessary. Stock airbox and filter are pretty good. I will start with those in my project but might later on try Jolly's airbox).

    Do you have 40 oil jet in clutch side? I read somewere that putting 40 jet will increase oil pressure..

    The .40 jet is to make neutral easier to find, has nothing to do with oil pressure

    But if you think about it? More pressure before jet..

    OEM jet. So far no issues finding neutral as I have learned to live with the quirks. Let us see how the TSS slipper changes the affair.

    The oil pressure is controlled by the oil pressure relief valve, not by an oil jet.

    A quick question to those more into Rotax cam timing (Amauri, Derbybrit, Gabro, Micah etc.)

    We got the rear cylinder timing to IN/EX to 111/111.

    Ran out of space to manouvre. How does that sound for timing. (Goal was 110/114)

    The day was much wasted as we got on the wrong track as the cam chain was not tight and messed up the measurement and we did silly things. Eventually we put a M16 bolt to squeeze the tensioner to keep the chain tight during the measurement and got to the result above. Live and learn.

    Next time we do the front and hope to get near near 111/111 if that sounds OK.

    Edit:

    That is standard 2004 Gen2 heads in a 1060 BB.

    Additionally, do I need to worry about the piston to valve clearance?

    I’ll get the exact degrees the next time I am working on it.

    111/111 could be a nice timing for an "all around" motor.

    usually there's plenty valve relief clearance with those 102mm pistons, and that timing is nothing extreme. You may jump the check but i would anyway stick a thick lead wire in the spark plug hole, have 2 complete turns of the motor, and see it you have at least 2.20mm at intake and 2.80mm at exhaust in valve to piston clearance.

    Those are the thightest value i use in street motors (but i usually ends in the 2.5/3mm region)... done even 1.8/2.2 in race motors but it's very tight.

    Cheers Gab. Once the engine is ready to go to the frame I’ll drop you a note about a chip. Also, some questions about running it in will follow here but later. We have a plan for that and I’ll test the idea here.

    At 111/111 you are perfectly safe on valve clearance between valves and piston. Power band will bias mid to top of of rpm range but this is good really with big bore which makes so much more low end torque anyway.
    Diminished expectations is the key to happiness in life.

    i've just started a new job.. a 1102cc Caponord!

    tested yesterday the base run, 113hp. Std motor with full 52mm custom exhaust with Akra can, 51mm Futura TB's and open airbox.

    i'm gonna built a new motor with 102mm piston in steel liner cylinders, RSV ported heads of mine, and '00 RSV cams. Let see if i can get 140hp's out of it
