I have the same bike, I went for a 47mm bore instead of the 44mm bore original and tuned it perfectly: 12 holes diffusers in the carbs, 3D printed specialy designed velocity stacks for the carbs, 90/100 jets instead of the 88/100 as well. I went also 14 teeth front and 38 teeth back (which gives a little bit more acceleration over stock). I switch to 15teeth front for long summer rides though. I top out around 130 at 12.000rpm and 135 at 12.500 rpm, and since I lightened my pistons and have a good carb set-up, it goes to 13.500 rpm with no problems for short bursts to maximize acceleration. It does not cost much if you do it yourself and really makes a difference (the top speed is the same but it takes 8.5s for a 82 kgs rider to go to 100 km/h). I have video on my channel if you want to compare the acceleration.
It's full power. 17Ps is required to put out 130Km/h with the cowl installed. It's a sign of a well-tuned engine. It's an enviable country to be able to run on the highway. The only place in Japan where we can test the potential of this machine is the circuit. Thank you for posting your precious video. Early 1977 model, from a viewer who owns it. I would appreciate it if you could watch my video too.
@@teppo233 i remember it well. I loved to rev it. You can't rev an actual bike without getting too fast. You could ride so long with open throttle and horny sound!
HEY, Bike is orginal.I have changed only the primary nozzles 88 -> 90 - size. I have also Honda Goldwing GL 1500. weight over 80kg. I have been in many times skiing in Austria beautiful place.

It was bikes like this that gave me such a respect for Honda.
I agree, a great bike and effective when it is their position.

Ok, my bike is standard, only the main nozzle has been replaced according to the recommendations 88 - >> 90
Engine vibration??
フルパワー仕様ですね。カウルを装着して130Km/hを出すには17Psが必要。調整の取れたエンジンの証です。ハイウエイで走れるなんて羨ましい国です。日本にはこのマシーンのポテンシャルを試す場所はサーキットしかありません。貴重な動画を投稿していただきありがとうございました。1977年初期型、所有の視聴者より。私の動画も見て頂ければ幸いです。
I had the same at the end of the 80's.: I have always been very happy!!!!

Can you not go on highway with 125cc? In Japan
thank you for your reply.
In Japan, motorcycles under 125cc are not allowed to ride on expressways. On public roads, it can only go up to 50km/h.

thank you
Great to see this video, great bike
thank you, yes, I agree with Honda has done a wonderful bike.
@@teppo233 how much HP does she have?
there are several versions of it.
Thanks
高校時代(45年前)に乗っていました。(1978年式)。8000rpm以上をキープして走れば、音とスピードが素晴らしかったですね。あ、ツーリングもイケましたよ。
Bloody Brilliant, my 125t did 85mph stsndard.
This was my First motocycle in 1977.
great bike isn't it
