Hi, now I have one of this beautiful machines since two moths, I have bought semi wreked and now im putting new fairings have changed piston, oil, cleaned all the fuel circuit and cilinder ports etc.. Now im noticed that the water pump have a little leak, at the front left part of the engine case, only few drops but i want to fix it. What is the problem anyone knows? Are the oils seals and o ring from the pump system? If its the problem..i have to put silicon or ptfe oil between the oil seals? Thanks
The cause seems to be degradation of the oil seal. Please apply Molykote™ 111Compound to oil seal. If the water still leaks, the water pump shaft also needs to be replaced. I will exchange water pump shaft and oil seal at the same time.
@@PochiRS ok thanks, i have ptfe grease and i was not sure about molykote is the only grease recommended, I have ordered molykote 111 compound 100g. How can I know if the shaft is not ok? I want to fix it next week and i think that the best solution is that you said, so I have to buy now water pump shaft in Aprilia official shop. Thanks for that quality on your channel, in that great videos and the feedback at the comments section. Keep the good work man, I'm excited waiting some NSR 250 videos. I also have an NSR but mine is a little bee, i have the 125 version, hard as a rock haha.
mine with full gianneli and no filter got 29 hp then i put 140 italkit dna fliter again the full gianelli a keihin pwk 33 and a vhm head and got 45 on dynojet
is it true you cant drive 2 stroke engines for long distance? especially on steady RPM on the highway? (i heard it wont get enough oil to the engine and it would blow up. cause the 2stroke would only pump oil when its been reved, not on steady RPM. pls let me know if you have any info, thank you
no, 2 strokes aren't for long distances. They are great bikes to ride with friends and probably the most fun. But not for long distances, especially on high rpm
Hi Max, The rear wheel output was 35 hp. My NSR250R rear wheel output is 70 horsepower over. Considering the displacement at 140cc 35hp is never bad, but not good. I think that it is an ordinary result.
35 HP are 35,5 CV. I believe that this is a good starting point. 35 HP at the wheel means 38 HP at the mainshaft. BC Engineering said me that the 144cc at maximum arrived at 39 CV, don't remember if at the wheel or at the shaft. I believe that you can continue to work on your motorbike to increase the power, maybe with the compression ratio or a different exhaust. I remember you have inside your Rotax the steel countershaft gears from Rotax Max. They probably drain power and acceleration because they are more heavy than the Delrin gears, for example.
I do not use steel countershaft gears now. They are reliable but too heavy. I do not use a water pump and oil pump, so there is no possibility of putting the engine in jeopardy when the resin gears is broken. So there was no need to increase reliability. By the way I have not measured power of 125 cc.
I believe that the 140cc has no less than 3 o 4 HP more in front of the 125cc. An original 125cc probably is 28HP at the wheel, 31 when improved. If very well improved a 125cc can reach 37HP at the wheel but is no more usable under 9000 rpm and it must be rebuilt after less than 1000 km. Keep in mind that with 15cc more you gained both torque and HPs. You can gain more HP working again the cylinder inside but again you will lose again torque at low rpm. I see that you run on short tracks with short straights and many curves. May be a more elastic and torquey motor is more usable and fast than a super powerful one that has no torque. But only you can decide what is better for your performances.
@@PochiRS yes it is But you must be really good at porting and also you must talk with some aprilia's racers in italy there are a lot, they speak in english and they can help you.
I have 100 octane from ENEOS. ENEOS is big oil in Japan familiar with Moto GP YAMAHA Works. Furthermore I am using an octane booster to improve 4 octane.
Yes that's a good result. You can spend a fortune and not get much more gains. Its funny ppl think 140cc = more power, but on a dyno the genuine aprillia barrel gives 1hp more than makita n same as italkit 140cc barrells. 35/36hp is great, to get to 40 is going to be hard and expensive lol
big bore kit buys you more torque, more important than HP gains. I love the way this spins up, so quick.
I agree.
And the more torque you have, the easier it is to ride.
As an RS owner all I can say this is wicked bro,nice one :D
2 Stroke Power good old time.
It's a bit lonely.
That's one beautiful rs125
