    Replaced old spokes rim to tubeless sport rim. All back to business.
    AAP sports rim + tires + bearing..etc install by shop. Bring back pasang jee...:biggrin:

    Old carburetors replaced, will service old carb + new main jet, pilot jet.
    Cleaning, oil change, scrap off any rust, wipe off old dust...etc.
    So is a temporary minor restoration to get my ex5 to move.

    Alway reconnect the vapor hose from the bettery to dispersed out battery vapor outside the compartment. Its normal for the hose to be missin. u can use aquarium air hose.

    So far from the picture its just surface dust so no worry. The sponge air filter is known to decayed and clogged the carb when no periodic maintenance is done. I just skit the sponge but kept the wire mesh.

    U upgrade to sport rim just like what i did when i started to ride to work. Now i am itcy to go backwards by using spoke wheels modified to be tubeless. Been hearing mixed opinion and review in this conversion. This or gold colour 6 spoke aap wheels as my rear rim bearing hub is worn out, need to 'alas' the bearing for perfect fit.

    Now mileage is 96k km. i will wait for it to be 100k km before deciding on engine service or minor upgrade. 53mm block with carb setting should be enough for daily ride.

    using tubeless on spoke rims is very messy.

    How will you keep the air in? Got to seal all the spokes? Moreover the rims may not be build to hold tubeless tyres.....

    got kit for sealing the spoke.
    feedback is like leinzz mentioned...messy.
    i too have doubt on the rim lip if it can properly seal tubeless tire.

    Spokes wheel can do tubeless. I opt for easy sports rim. Anyway still keep the spoke wheels. hahaha

    Good for u...stock is sufficient.

    My route to work involved straights where the bike will reach 80/90/100 on the speedo and stayed there unless the lights turn red. It will do this everyday on weekdays without fail. Thats how tough these machine are. My OCI is monthly basis regardless of mileage and always on the 28th. 28th coz gaji masuk which is an easy tracking method...hahaha

    MOU have been obtained with finance minister on getting another bike but i am afraid if i go for it i dont have time for both bikes coz the EX5 will NEVER be sold.

    From your pic, is that 80/90 size tire for the front?
    From my experience 80/90 up front makes handling less nimble and kinda weird when cornering. Stock size is 70/90.

    Normally std kapchai stock setup is 80/90 rear and 70/90 front. Maybe the sidewall is taller on 80/90 thus it will flex causing the weird feeling at the front.

    Wanna ask otai here about setting ex5 carburetor. By youtube, adjust higher idle then adjust air to get higher idle.
    Lastly adjust to normal idle rpm.
    Any good instruction for stock setting...tq

    I have never understand how to do it. I did it once long time ago after diy servicing the carb but result in lower power. could be previously it was setup for a tad more power at high end.

    I screw in the air IN to the max (will cause the engine to idle abnormally ) and adjust the idle slightly higher. Then i turn the air screw out until the engine starts to idle or firing normally. Give it a couple of rev and it should rev up smoothly at entire range. If not then need to fine tune little by little. I get very good fc with this setting but loses a bit of breath on top end.This could be the stock setting.

    Need good communication and listening skill to understand what the engine note is telling u.

    The feel of ownership is hard to express.
