hey guys whats up just bought a 2000 xr50 that sat in my friends garage for the past 2 years he put a 88cc-big bore kit from brand x minis from ebay
when i got the bike it was missing the kicker so i couldnt try to kick start it and finelly got the kicker when i went to start the thing it was really hard to kick it like the motor is seezed im able to kick it but its very hard its not soft at all what can this be please can someone help me figure this out thanks guys

 

it should start throw a new plug in it and fresh gas try kickin it then should fire right up let it warm up then for like 3mins

 

I'm not sure if it will start cause it feels like something is restricting the piston

 

It should start. If its got good compression it should fire. Make sure you got yhr kill set in the run position and the key in it. I would hate to read this later on and your boy sold you some bad ****.

 

Who put the big bore kit in? If they didn't know how they could have not seated the rings right or a whole number of things could be screwed. Does it sound bad when you kick it over? You better do some research on the install. There is a reason he never rode it. No one owns a 50 and doesn't ride it. Unless they are a *****...

 

ya hear ya there buddy just kick it sumtimes wit key offf and see if gets better and check tha oil in it. make sure the key is on along wit the gass. and how long has it been sittn and was it ever started then

 

the thing sat for 2 years checked the oil and its good nice and clean

 

im trying to kick it over with the spark plug out of it and its really hard like its got alot of presure my boss has a 04 crf50 and his all you got to do give the kicker a slit push and it almost sounds like it want to fire write up

 

the reason he didnt ride was cause he moved to new york city

 

Is it in nuetral ? Can you spin the rear tire by hand ?

 

yea it rolls good and the gears are good

 

take the spark plug out and kick it over a few times. Also check and adjust the valves because they could be way out of adjustment.

If that doesn't work then check the timing on the cam because it sounds like the exhaust valve isn't opening causing all the pressure you are feeling.

 

what he said^^^^^

plus if it sat for 2 years, firat thing you should have drained the gas in the tank, and carb. if you do get it running and it runs like poo, clean the carbs. the jets are prolly all gummed up from the old gas.
good luck

 

it should turn over if the spark plug is out.... try push starting it..?...
