My first bike... a candy red one in 78...top speed was 142 kpm then it started to starve , I found that the marine 2 stoke oil available at the time (blue) reduced the plug oiling up problem resulting in the bike running on one cylinder !!
Ben vous les anglais vous êtes toujours différents des autres pays de l'europe 😂😂😂, nous le quick de démarrage ce trouve à droite et le ralentie se trouve à gauche
I had a GT250M with the 'Ram air' system in 1975 and a GT250A years later. The noise is unique! Slow as pooh mind you. I was always being burned off by RD 250's and when the LC came out.............Great memories😀
It looks terrible it's called a cafe racer it's got 1 piece seat made of aluminium and pop riveted together and signs on it myself terrible job put it back original waiting for abuse
My dad had one exactly the same in the early 90s that he used everyday for work. He bought it from the " loot" for 350 and it was mint!. If only we had a crystal ball ha. His would start first or second kick every time and went like a rocket . This one sounds like its struggling a bit?
Servus! weißt du noch wie du das mit dem Hauptständer hinbekommen hast? Am Originalauspuff ist ein Stopper für den Hauptständer verbaut. Wenn ich diesen durch einen Slip On ersetze, fehlt dieser. Meine Sorge ist nun dass der Hauptständer kontakt hat zur Kette oder sonstiges. In deinem Video ist dieser ja noch verbaut.
Servus! Ich hab das Motorrad zwar schon ein paar Jahre nicht mehr aber einige Fotos hab ich noch. So wie ich das auf den Fotos erkennen kann war am vorderen Rohrstück ein Anschlagwinkel angeschweißt in dem du den originalen Anschlaggummi einstecken kannst. Ich hatte damals jedenfalls nichts am Auspuff ändern oder anbauen müssen. Sollte also auch heute kein Problem sein.
Ich hab gerade weiter unten in den Kommentaren nachgeschaut, da hab ich schon mal was zum Anschlag geschrieben. War wohl doch kein Anschlagwinkel verbaut. Lies einfach mal weiter unten nach.
Moin Moin, wieso hast du zum Ende den Auspuff von Unit-Garage nicht dran gehabt? Hast du da irgendwie was eingetragen bekommen o.ä.? Oder jetzt den Originalen dran gelassen? LG
Hi Niklas, der Unit-Garage Auspuff hat ein e-Prüfzeichen. Ich hatte den aber trotzdem bei der TÜV-Abnahme mit eintragen lassen. Danach bin ich ca. 1000 km damit gefahren. Der Auspuff war mir aber trotz DB-Killer viel zu laut. Hab dann noch etwas mit der Geräuschdämmung experimentiert. Hat aber nichts gebracht. Ich hab keine Ahnung wie die Italiener sowas durch die Abnahme bekommen aber der Topf war mir echt zu laut. So hab ich den originalen Topf wieder verbaut. Hört sich ja auch nicht schlecht an. Den Unit-Garage Auspuff hatte ich dann verkauft. LG
@@MrStarfighterf104 Alles klar danke dir für die Antwort, finde dein Motorrad Umbau unglaublich hübsch und werde ihn als Beispiel für meinen nehmen, gibt es noch irgendwo mehr Fotos von dem fertigen Umbau ? LG
@@niklas1936 Den Fender und die Rückleuchte hatte ich, glaube ich, bei Kickstarter.de gekauft. Wobei ich den Fender auf der Oberseite abflachen musste. Kann man aber glaube ich auch im Video sehen.
@@niklas1936 Hi Niklas, danke für das Kompliment. Natürlich habe ich noch andere Fotos von meiner 7T5, aber ich habe keine weiteren Bilder mehr im Internet veröffentlicht. Ich wünsche dir viel Spaß beim Umbau deiner K75. Wenn du noch weiter Fragen hast, kannst du dich gerne wieder bei mir melden. LG
I had one, loved the big petrol tank, always had to clean the contact points that keep burning up, couldn't go past 90kmh haha. The cool thing about it is the gear box. There is a neutral between 5th and 6th gear and another one between 3rd and 4th if I remember correctly hhh
For two-stroke advice - you followers can reach me at victormontijo@yahoo.com... Beautiful bike! Congrats on getting back into shape and sounding great. The simplest way (but risky if you are not careful!!!) is what I do - put a shutoff (in-line petcock) on the oil supply tube that I turn off when parked for extended periods. On some of my more "leaky bikes" i have to shut this valve off even sitting overnight, others in my collection can go a week or more. But you all know what can happen if you ever forget to turn the valve ON when you go to ride the bike - BEWARE! For me, I have so many of these old 2-strokes that it total habit for me to turn the "oil petcock" on whenever the "gas petcock" is turned on and vs vs. I understand that Suzuki 2-stroke outboard engines have replaceable in-line automatic check valves... Good luck with yours!
würde mich auch interessieren?!... der harry hat ja noch ein video hier mit dem original auspuff. da klingt der zard schon etwas ‚kerniger‘ mein ich...
When I turned 15 I talked my parents into buying me a brand new 1973 GT250. Your engine doesn’t look right to me. Is it missing the RAM Air scoop? Maybe yours is an older version? As I recall, mine was dead reliable and easy to start once I got used to the differences in control manipulation between a cold and a warm start. I had to learn how my baby liked being started. It’s a thang.
The second versions from 1976 onwards ditched the Ram-air-system for conventional heads. Those models were slightly more powerful than the Ram-air-ones, even though they needed to rev higher. A two-stroke being hard to start after 20 years of standing around is pretty normal.
i had plenty of these old killers back in the day ,kicks in on 2 cylinders then runs on 1 as he pulls off , petrol turned off doesnt help and a leaking tap with seal gone , may have crank seal on way out too . lovely bike
Nope. I am an old guy that grew up all around Suzuki two-strokes, and I know these bikes front to back... I have currently have 28 Suzuki 2-stroke street bikes (not a typo!), many GT's, and now even more of them are RG's (yay!). Younger/less experienced 2-stroke enthusiasts please read on: It is indeed running on both cylinders, it would never idle on only one cylinder. The smoke you see on the right cylinder is one of two things: most likely: a) All two strokes with oil-injection have a "check valve " on EACH oil line going to the cylinder/crank bearing... this is to stop oil from dripping into the crankcase when parked... the oil pump alone will NOT stop the oil from flowing through it when parked... the force of gravity acting on the oil in the oil tank will pass oil through it, and ALL injection pumps (that I know of) need some mechanism to stop the oil flow when it is parked (for extended periods). After time, these oil check valves fail to stop all the oil from seeping past and allow oil to dribble into the places that the lines are going. If parked for weeks, months, years, I have seen extreme cases where so much oil has seeped into the combustion chamber that the engine would not turn over at all (hydraulic lock). Most folks that ride vintage two-strokes are NOT aware of this problem but the check valves leak when they get old. There is a tiny ball bearing being pushed to oppose the flow by a tiny spring... under normal conditions the oil pump pressure is easily enough to "crack" the seal and push the ball bearing open against the spring... all part of the design. But over time the (chrome steel) ball bearing begins to form tiny "pits" and local defects - much like fork tubes do. When this happens, oil begins to seep past. It is such a gradual process that the owners may not realize this is happening - especially if the bike is ridden regularly. As you can guess, this almost always happens on one side before the others. Whichever cylinder has the offending check valve will smoke terribly at first start-up then "clean up a bit" as the you keep riding and burn through all the excess accumulated oil. But when you park the bike, the process repeats. As an older 2-stroke lover/restorer, I am so amazed at how many people think that this "smoking" is a natural part of two strokes (nicknamed 2-smokes!), but it ABSOLUTELY IS NOT! Back in the day my old GT's, Yamaha RD's, Kawi triples NEVER smoked like this - even on start up. If you got a smokey two-stroke - especially on just one side, or one side worse than the others, etc. this is almost certainly what it is. Now the other thing this might be is b): This bike's right cylinder needs a crank seal. If this is the case, the smoke you see coming out of the pipe is actually transmission oil being sucked in and pumping out the pipe. The difference will be in the way the visible smoke SMELLS... Trans oil smells ugly - a bit like like burning rubber... if it's excess 2-stroke oil seeping in, it will smell like the 2-stroke oil itself, which generally has a fragrance added to oil to make them more acceptable. I hope this helps you fellow 2-stroke lovers! Cheers!
Too much information. Mine was shite. One pot was always cutting out. The points drifted too easily. My test instructor passed me because it was raining. The chain and sprockets were made of soft monkey metal. Rubbish bike.
Very good and detailed info. Please also provide information on how to solve this problem in detail. Many people would benefit from your knowledge and experience. Thanks again.
vmontijo AWESOME WRITE UP. I love reading by someone who really knows what they are talking about. I'm looking for a nice Two Stroke that I can ride and not leave me stranded, not to just sit around.
