110cc and 49 cc dirt bikes

[Dave.B]

ok, i as title states i got 2 dirt bikes and yep both are not running, the 110cc is apparently a siezed motor, i hadnt rode it for few months cause of few things i needed to fix, i got on my high horse fixed these probs rode it gently for abit then went to open it up down the street and from 1st to 2nd gear the back wheel locked and hasnt moved since, i cut the engine and the kick start is jammed aswell as the front cog, now i havent actually had it checked but from phone calls the people are saying its siezed, i have no hope fixing this myself but if any of you have a different and cheap theory in which i can get it running feel free to let me now, now the bloody 49 cc thing is only a week old, today after reading this site i set out and bought myself a new plug, fuel filter and lines, after puttin all these together it seemed to keep cuttin out, after abit of fidling around i got it going smoothly until the ever lasting problem everyone seems to have when it dies or wants to die in high revs, yet again after searchin this site i figured its fuel related and went about to check everything over and it seemed fine so off came the carby, cleaned that out or so i think i have, with the pin and float all coming off when i took it apart ( me not reading the carby thread) i didnt know a pin n such was gunna come out, so i put it back together in a way i think is meant to be and it looks quite right and now it wont start, now wat do u guys think is the problem there?

i was told that i can fit a 125cc engine to my 110cc frame and convert it all over no worries, now does this seem right to you fellas and also would anyone recommend this?

the 110cc is 4 speed auto
49cc is just a simple cag model

and while im here seeing i want to get myself a 125cc moto if anyone is interested in buying any of these pop me an email on defacto_hardwear@hotmail.com im located in the sydney area

mate will u sell ur 110cc bike i dont mind da motors sized because i need a frame

[mac90]

the 110 could be many things sized just means she wont turn over could be in the bore its self
or a timing chain broken and siezed valve stuck open or bent!! bottem end dramas and 20 other things
u need to know a lil more about a 4 stroke engine if even thinking about repairing it and it may even be cheaper to grab a 125 or 110 3 valve oil cooled engine they should fit any frame configuration that ran a 110 even a honda

the 49 cc it is probbly a carby problem for sure if its a standard carb the taps can sometimes be restricting flow kinked lines vent hole in cap , fuel filter etc... etc..
as you have read in other posts but blowing the main jet out with compressed air and Another clean out wont hurt it
even try to borrow a carby from a friend who has already upgraded their carb and kept the standard for a spare

last is the coil but if it ran before then its still getting some spark, try disconnect the killswitch it could be shorting out
its trial and error but sounds verry much like the dreaded fuel problem almost all bikes have once or many times

yeh 49cc bike shouldnt be a problem just not bothered to look at it considering i was at it all day sunday fixing riding bla bla bla, yeh i dont know jack about 4 strokes, ive sorted it out and am going to put a 125cc 4 speed in it with a yamaha miki carb, should be fun huh, does anyone know what kind of speeds i should be looking at with that?

[divyupon1]

i have a lifan 110cc engine in my pitty an have hit 80-85 km/h but it depends on what type of gearing you have on it cause i ride on alot of straights so i changed my gearing so i get more top speed, i raced a guy on a atomix 125cc and i bet him on the straight but around a track he would beet me so yeah you can get all types of speed out of ya 125 if the gearing is standard id say you should hit 80-90 km/h
oh an try to get a lifan 125cc engine not a ducar 125 cause the lifans are more durable

[Dave.B]

got the engine put in today and god damn it goes, got new exhurst, new cog, bigger wheels, new plug, fuel and air filter, and the new carby, anyone with sum knowledge of the 4 stroke engines could u tell me what else i can upgrade to make this a weapon?

u got any pics of the conversion m8? sounds good as. You can get postie bike CDI boxes that supposedly beef up the postie motor - so don't see why it wouldnt work for that one... $100 or so off ebay so they arent cheap
