    I shoud post some picture on my bike, it is not completed yet.
    Next thing i will do is fabricte a new gastank. i should remowe the upper frame tube and replace it white a 3inch tube 1/16 thick. The Expansion chamber is from a Yamaha DT50 and works very well on the engine.The muffler is modified originale muffler whitch is modified white parts from a RZ350. I should also replace the front fork to one white suspension and a discbrake , i think it is
    necessary when the bike is going 40mph. The engine has got a "Blueprint" and it works great

    A Husquavarna tank with the chrome would look great on it.

    Update! My bike project

    Hello! A little update on my bike projects. I have driving about 100miles with my bike, and it works very god. it has a topspeed about 64kmh. All that has happened is a broken aluminium Inlet manifold
    The chinese quality of aluminium is not so good. So i have to make a new manifold in steel.
    I have also made a develoment of my bike, has anyone done this before? two rear rear sprocket.
    I think it vill be nice to have both speed and torque! so i have mounted one 36 and a 44 sprocket.
    Its very easy to shift from 36 to 44 you only need some chain links!
    And i have also made a new chain tensioner instead of the uggly oem version that followed by the engine kite.
    Next step is to remake my expansionchamber to get more torque on lower rpm. Its start working about 7300-9400, if anyone has driven a ypvs yamaha, its feel the same but in a 60cc way!! not so many hp. So i vill make the header a littel bit longer for more torque on low rpm.

    Re: Update! My bike project

    Looks good........so it is a manual switch between the 2 sprockets because of the added chain links?

    Now i had make the header a littel bit longer (2,5inc) for more torque on low rpm, and with a 36 sprocket i hit at last the 40mph (GPS) 42mph with a cyclecomputer. Next step is new carburator and 45mph is the target for mexct2

    The tune pipe is from a Yamha DT50 .I have build a new header so it vill fit my bike. It works verry well, when i drive for longer rides it is much smother and less vibrations white a 36 instead of a 44sprocket

    Thanks A buddy of mine has a very similar pipe coming around the left side looks Identical.
    His bike runs quit well. He blew out the wrist pin cage over revving it though. I like the left side route.

    His came off the same brand bike too I think. Put a bigger carb on it added about two and a half or three inches to his header. Had to cut the expansion chamber down the middle and re clock it to fit the frame it was a project.
