    Hello tom . Just simple advice for 2stroke lovers . After a month even a year our motorcycle doesnt been been start , we need to put a 1-2 2t cap to the piston so the piston doesnt have a friction because our piston is in dry + have vapour condition . Its also make our starter and combustion become more easier and the block and piston doesnt have any scratched . If want to do more before we leave it for a month even a year fill the gas full tank so our tank doesnt have any rust , fill the 2t oil in small amount so the pressure become lower and the 2t doesnt kept flowing on the engine , close the muffler hole to prevent dust and steam from entering the engine and causing the exhaust rusty and put the piston on the det end so our piston block is in free condition . It will make our bike become more long lastings

    The thing is with these little bikes as I own three rs125s all SP models from factory full powers one being a all out race bike one being a road / track bike and one being a collectors bike is that my 41hp set up on my road/ track bike is very fun and also suprisingly reliable as long as you have the correct jetting on the bigger carbs mine has the 39mm carb they’re fine, 17/40 gearing top speed of 114mph but it does cost a pretty dollar to tune this far , vforce reeds and vhm cylinder heads make a massive improvement on these bikes obviously you’re riding it daily so you wouldn’t want it to be competitive with a 600cc bike but if you want more all round power the vforce 3 reeds give a massive improvement in low end mid range and top end including responsiveness a vforce 3 reed kit for these bikes around around 130 pounds so about 160-170 dollars but will give you 3-4 horsepower on the dyno too

    • @thesweeneyboys2974
      @thesweeneyboys2974 2 года назад

      The v force 4r reeds can be fitted which have the petal stop you’re talking about but on the dyno it gives a more unnatural curve and has more midrange

    • @thesweeneyboys2974
      @thesweeneyboys2974 2 года назад

      Other ways you could gain more pulling power is through a vhm or italkit cylinder head, actually improves the bikes cooling and will run more crisp as the stock squish clearance is quite large even with the smallest cylinder base gasket on , they’re not too prices but gives power through all the rev range without harming the engine

    Well done, Tom. I have a Krr 150 2t from Kawasaki. Sounds similar like yours 👍🏻 I always wonder about the speed limit in Australia which is shame you can’t enjoy the full potential of the bike. Here where i live everyone is changing the sprocket setup for top speed 😅 It’s mind blowing sometime to think small engine like this can run up to 170+kmh. Anyway, thanks for the video!
    Cheers.

    • @tomdidit4216
      @tomdidit4216  2 года назад +2

      Hello lil pac. Thanks for your comment.
      I believe the KRR bike is rare in Australia. That extra 25cc can make a real difference over the total RPM range👍.
      There are areas outside of the city where I can open her up, however I chose the current sprocket setup to suit my day-to-day riding.
      I agree with you - 170+kmh is great performance for such a small engine!
      Long live the 2 stroke😎👍

    While you were changing the sprocket, there’s a little plastic clip to the left on the frame with a zip tie through it. Do you know what it’s for? I’ve just bought my RS125 and I’m working through sorting some problems out and working out what’s missing and what’s been bodged!
    Also there is a brass union connector on the crank case on the same side as the sprocket just to the right as you look at it, do you know what it’s meant to connect too? Mines open without anything attached but it looks like it should have a breather on it

    Hi Tom.
    Does your bike have the EFI ECU?
    If so is it drilled?
    It seems like my bike does not gain that huge boost when the power valve is supposed to open.
    The bike seems to be vibrate a lot more at 8k or above, but that might be normal. Yesterday was my first time applying full throttle.
    If you would not mind, check my latest video and look in the comment section, there I've put some time intervals where the "noise" appears when approaching 8k.

    • @tomdidit4216
      @tomdidit4216  2 года назад

      Hi Phillip.
      Yes my bike does have an ecu.
      There is a long list of reasons why your bike may seem sluggish in the power band. I believe the Aprilia RS was shipped around world with different restrictions. These include ecu power valve and exhaust restrictions.
      Sorry I can’t help further mate.

Can you message me or give me your email to just have a few words?

      I'd actually like to hear about this, Bought an 08 model last week and has the same issue although I couldn't get it passed 100km/h on the highway ride back, She has the ECU Done and also a new exhaust! and also, if tom wouldn't mid, I have a lot of open pipes on mine from the carb and also a pipe that plugs in the bottom, what pipe plugs into the bottom of the carb!

      @Paul Mickiewicz it's the 28mm Delotto, vbsh28nif I remember correctly, just giving the bike a once over as she needed adjusting, back down to sea level now

      Agreed. Thanks Paul.
      There are many variables as to why the bike is under performing👍

      @Paul Mickiewicz Hey Paul, I am In South Africa, I will check all of those, I haven't checked the PSI nor the hearing set up yet but I will do today but I do know there is a power cable and it's working, I have had a look and I can see the hope drilled into the CDI under the set.
