      Did you use the stock head, or did you have to upgrade it? I bought the 52mm bore piston and jug, but the head is stock and too small (piston hits the head at TDC)

    Not sure if i've commented here in the past, but even if I have, I would like to reiterate my opinion on this video and the author of the commentary.
    This is the most comprehensible step-by-step installation of a Bore Kit on a qmb139 engine that i've come across. As you've also stated in the video, you've done this many times and get overconfident; however in other tutorials it seems as though they skim over tiny important details because of that overconfidence that you seem to explain very well.
    Crucial information for beginners and seasoned professionals alike.
    I used this video as a reference for installing my first Bore Kit, and she ran wonderfully. I will use this video for further kit installations.
    Thanks, Rouse Garage, for being so thorough and taking your time. Teaching is an art.

  • @suzannecouillard5312

    Excellent video. My only recommendations are to also use assembly lube on the camshaft to avoid a dry start, and avoid getting any sealer near any oil passages. If sealer makes its way into the oil system, it will ruin your day.

    Hey, I wanted to thank you greatly for posting this video! Definitely the most comprehensive set of instructions I have found. I just performed the steps on a Kymco 2023 super 8 50x. They were pretty much identical with the exception of the housing had one extra bolt. Otherwise, it was spot on. I ended up using a zip tie to keep the chain safe and one mistake I made was not pulling the chain far enough out when I was trying to push the assembly back together. So the chain got caught a little bit nothing happened, but, just caution for anyone else when they were putting everything back together. Again thank you very much for a fantastic guide!

    Great video. I would add to check the flywheel to make sure it's still at TDC (the "T" at the mark) before closing up the engine... It's not impossible for the flywheel to get turned/rotated while you're trying to get the rings and piston into the new cylinder. You should recheck it before lining up the camshaft and timing chain.

    The rings, I have always put the gaps 180° from each other, I have seen others do 60° but that doesn't make sense to me, 180° always worked for me! And I always put them at 12 & 6 o'clock, I also like to polish the dome of the Piston, to help prevent carbon build up, and reflect heat a bit, possibly. It wouldn't hurt to slightly lighten the Piston, without weaken it!! I just done one of these, I ported the head and unshrouded the valves, went to a A9 cam, and 20mm carb, I'm about done, and ready to see how she do!

NO issues running , idiling or in performance , it runs fine . Just knocks and its driving me nuts. Fresh rebuild last week. Thanks for the advise so for all the rambiling .

      Also put assembly lube on the cam, (both the bearings and the lobes). And for good measure, both contact points and the pivots of the lifters. Assembly lube is cheap, new parts are not - "An ounce of prevention is worth a pound of cure".
      May not be needed, but I always turn over any motors I work on by hand with the spark plug removed, to help pump a little oil before a hard start. These little motors are easy to do.
      BTW, great video. Only wish you did a before test run and an after, to see the difference.

    I'm going to put a big bore kit in my wife's scooter as well. On your video everything was stock except for the big bore kit. My question is do you think the larger valve head and big bore kit are worth it or does it add very little performance in relation to the added cost. I ask because you didn't bother with those upgrades. Also want your opinion of performance exhaust and heavier/ lighter rollers as far as actual performance high end or otherwise.

Maybe he should have said something but this vid is on the installation of a Big Bore Kit not tuning a carb just the bbk i believe i seen a vid in his list about carbs. But as far as the vid amazing! I watched tons of vids i tried watching ones with "non mechanics" doing it since im not 1 and figured they would do it the way i would (i was right) but i also like a few full breakdown vids and this is the best one i seen the little extra stuff like adding Lube to the Piston which makes perfect sense but never seen or heard it before. And using a tiny bit of gasket maker shit like that is great. 👍 good job and thank you. Dont worry you cant make everyone happy just know you helped a new scoot tuner out a lot!

    Great video. My only gripe is that you shouldn't use assembly lube on the parts before install. It's going to get into your engine oil supply. You should use the normal engine oil that goes in the engine. That is what is going to be lubing it when it is running anyway and using engine oil to coat your parts means that your oil supply won't be contaminated by the assembly lube which may not be suited to the engine.

      You're kind of right, but any competent and experienced tech knows to change the oil almost immediately after breaking in new engine parts.
      The factory uses the same lube, and it stays in the crankcase until the first owner decides to do maintenance, if ever.

      Thank you for the views and comment.
      We will be launching rousemotorsports.com in February, and will be selling the best quality big bore kits. As it’s not necessary to up-jet the carb, it is most definitely best practice if you want optimal performance.
      In the very near future, we will offer a big bore kit that will include a high performance carb.
      Thank you for taking the time to watch and comment on our channel!

    Great video man. I've got a 50 cc Kymco Agility 50. I've installed a performance carburetor and exhaust. Not hardly any changes in speed. Still only about 35 mph. Runs way better though. What kind of increase would I get with an 80 cc bore kit? Also will the oil pump still keep up?

    I have an idea for keeping the chain from falling while you're working. How about using a plastic chip clip? The small ones that are made to keep potato chip bags closed to keep them fresh. The chip clip could hold the chain while you're putting the jug on.

    definitely put a cire or pad lock(don't lock it) around that chain, don't let just hang. a 10 inch piece of copper core wire is best. This guy knows what he doing, if you don't, then put someone thru it to make sure it doesn't fall.

    And also theres an other pipe from that octopus that goes to a "pump" or so to the top of gas tank.

    things to know you should put a bigger jet in the carb and I seen in your video you loosening the vales after you tighten the head down I would loosening them first so you get a good tor. on the head because if you do not then could be putting more pres. on the head bolts but grate video like it a lot I have just got a 50cc rally scooter looks like a VIP to me for 125 with looks like 1.2 because it was lay down first ride to me but not bad few little markand I have a 2008 vento triton 49cc that has a big bore on it and I had to jet it up to make it run right

    If your kit came with an aftermarket cam gear and camshaft that only has 2 holes without the bigger 3rd hole, how would you time it? Also I can seem to fit a feeler gauge under the bottom valve even if it's fully turned out.
