Calculation of CC:- For RX-100:-(1/2Bore Square × Stroke × 3.14 ÷ 1000. That is 25×25×50×3.14=98125 ÷ 1000 = 98.125. RX-100 is actually 98CC. To calculate the CC You need to know the bore and stroke of an engine in mm.
@@SpeedyLio I have been regularly using RX-100 since April 1986.I do all the maintenance, modification s and overhauling myself.Some of the modification I have done:- 1)5 speed gearbox of Yamaha RXS-100 purchased in London, the model there comes with 5 speed gearbox.The complete set fits without any alterations.2)22mm Carburettor.3)Hy-Tech and Boyesen dual stage racing fibre reeds. streamlined and free flow reed block. From Singapore:1)115cc cylinder along with std,2nd,3rd oversize piston kit.2)Two piece Clip on handlebars. 3)115cc cylinder head. 4) Compression gauge to check the compression.because without proper compression the engine will not run properly,no matter how much adjustments you do. 5) Tachometer gear set along with meter and cable. Done port matching and raised exhaust port for top end power. Thanks.
Porting is basically enlarging the intake and exhaust while boring is removing material from the inner diameter of the engine. Both porting and boring help in improving the performance of the engine/ bike. Porting and boring have to be done correctly with calculated formulas or else the engine will get butchered. If u want to improve ur Rx or any two strokes performance just change to a performance air filter, good spark plugs and mainly carburettor has to be tuned well as the air fuel ratio plays a major role as lesser the unburnt fuel equals more power. Keep up the great work Speedy Lio🤘🏽
Some issues : 1. Porting formulas are there and it's not as simple as making the ports larger 2. A 175cc engine won't work very well because the crankcase is still designed for 135cc. If you bore out that much, then you also have to widen the head, which is possible but you can't change the crankcase 3. By Head porting he is probably talking about milling the head and reducing the volume of combustion chamber. This will increase the compression ratio, but there is one problem with it. The spark plug comes closer to the piston. That can cause more overheating issues. Its better to machine a different head with a smaller combustion chamber with the spark plug slightly away from the piston. Also, in head, there is squish band which also affects power range. If you change it too much, then your power characteristics will also change. Exhaust port height will also determine your head volume 4. 12 ports karne ki jarurat nhi h. 7 port me bhi Acha power nikala ja sakta h. Naughty nut ne 22bhp nikala h... with same port layout. 5. It would be better to modify the block and head to create a coolant jacket so that you can use a pump and radiator to make a primitive liquid cooling system. 6. block kharab hone pe poora block change karne ki jarurat nhi h. Sleeve bitha do ache se toh power theek se aayegi. Material aur port matching. Ye dono ka dhyan rakhna padta h
I hope so you know msk .. When his channel is started i have that strong feeling that he is going to grow very fast in vloggging scenery of india And i have that same feeling for you brother ✨ keep working .. Even i have rx 💯 1987 model ❤️
Ho sakta hai bro but mut karna agar tere pass rx hoto to . Bass timing set kr , side oil use kr . Aur aisa kuch bhi karne ki jarurat nahi hai isse tere l lag jayenge . Keep it og .
Bhai mera rx100 hai ,maine second liya bt kuch kam nahi kiya ek sal se chala raha hu , dikhne me takatak hai bt jaisa chahiye vaisa feel nahi aa raha chalane me , pickup kam lagata hai to mai abhi kya karu boar karu ya na
Volume of a cylinder - 3.14*r*r*h I don't think that 1 mm which is the last number of rebore piston will make it even near to 140cc Even if we talk about after market oversized pistons which goes upto 3 mm used for drag racing, will hardly make it reach 145 to 150cc. For making it 175cc with the current stroke length, you will have to drill out the whole cylinder leaving no wall that the piston can slide around.
Hi dudes good to hear your experience all about upgrading,in also have kawasaki gto125 2stroke engine it's really a powerful machine but I there is a problem that cylender liner is end and there is no availability of cylender in karachi Pakistan 2nd option I have is to insert liner in it and most Of the guys told me it's just wasting to install cylender liner it never perform as it were before,it always get seats during fast run.so please I need a suggestion from you guys should I install liner or not...thanks regards...
Agar porting kar rahe ho to mileage mein compromise karna padega.. ya to power ya fir mileage choice is yours lekin haa semi port me thoda jyada mileage milega as compared to full ported.
I'm certain that the speaker in this video has his facts inaccurate. One cannot increase 7 ports to 12 ports. One can only increase the size in the intake and exhaust ports, to increase the air-fuel intake flow and exhaust flow. All this is calculated. Also, the bore size, when recored, increases by stages of 0.25mm each. So, maybe it was the speaker's incorrect speech, but the RX's 132cc cylinder will not go up to 175cc or 200cc. This video is not accurate. Thank you.
Boss..please let me know from where does your friends have done modification in engines. Who was mechanic. Bcoz I want to do same thing like your friends. I want to increase power etc. I don't care about mileage.
Stop posting crap like this, your other videos are good. But don't get clowns like this who do not know what they talk . Saath port ko baara kar diya? Seriously? 😂😂😂 . And 175 to 200 cc ? 😂😂😂

Do we need to install bigger jets or can we keep the stock ones?

If you port the cylinder than the problem comes of engine hot other wise if it's stock you can push the bike as much as you want
