Sounds like you have a blown head gasket. Does it go away when the engine warms up? Does it "chirp" when you blip the throttle? The changes you made had nothing to do with this, but when you started the cold engine and twisted the throttle to hear your new power the head gasket went away. Harmless until it gets real bad and does not go away when the engine heats up.

How to change piston on Jonway 50 cc 2012

Air cooled 50cc motors usually have 4 long bolts holding the head on, they go up through the 'jug' and through the head to bolts under a decorative cover or just out inthe open. remove nuts or entire bolts and then use a mallet to whack the 'jug' (cylinder) to break it free of the lower gasket, pull jug up and off piston, remove old piston by circlips or other retention and install new one. pinch rings and work jug back over piston, lower onto case gasket (if you didnt rip it removing it) and button back up. Check cylinder before replacing piston to make sure a new one will work. If the walls are scored, you will have to get it bored and use a +.25mm piston.

Not realy a problem more of a question I have a 92 suzuki intruder 1400 and was woundering of i would b able to take the back jug off the bike and turn it around so the exhaust outlet and carb inlet could...

Not really a feasable option, the chain or belt driving the cams would be on the wrong side and the cam timing would run in reverse, there would be oil feed problems,the cylnder bolts would not be symetrical, etc in other words you would probably need to recast the crankcase and the rear barrel, make new cams,inlet tubes and exhaust.
but good luck with it

How to add coolant vulcan 500 en

If this bike has a coolant jug on right side hidden behind a chrome cover, you can add coolant there by taking that cover off and there should be a rubber plug on top to take out. If no jug, you will probably have to take fuel tank off and fill through radiator cap.

I have a 97 scrambler 400 4x4 i stripped some of the jug studs out of the jug when i went to tighten the head down how can i fix this problem w/out taking out the jug? I am also not getting any power to...

hi buddy maybe a blown fuse on the head light or blown bulb also the only thing i can think off is you taking the studs out by putting 2 nuts on the thread and tighten them together then on the bottom nut turn it anti clockwise and the hole stud will come out then pop to your local hardeware store and get some studded bar and then cut to the length required thats it buddy

Polish and port

Take some duct tape and put it around the shape of the new port opening. Now put on a second layer of duct tape. This does two things. First it outlines the size and shape of the revised port, and second when the rotary grinder skips out of the port, (as it is going to do a bunch of times), the grinder bit won't nick up the cylinder wall.

The only polishing needed is on the face of the new port area. Give the burned gas a smooth exit into the exhaust pipe. Don't go too extreme on the changes. Too much and you loose performance. This is the voice of experience talking.

Please rate this answer. Thanks!
