I have a 1984 Honda xr250r dual carb. My dad brought it when i was a kid but as I grew up, he didnt enjoy riding anymore. The bike stayed in the shed for around 6 years with nothing done to it, not started or anything at all. Recantly, I decided to try fix it up so I can go for trails with my mates. I have replaced the spark plug, cleaned the air filter and changed the oil. I was informed by dad that just before he stopped riding it the bike got new jets, new piston rings and new pistons in it. The bike starts, but after 1 or 2 kicks fuel just starts **** out of the fuel deposit when the bike is not started. When it does get started after a while it calms down and stops but the bike will only idol with the choke on. It blows out alot of white smoke aswell. When the choke is off it will stay started aslong as you keep reving it, but if you stop the revs will lower and it will eventually stall. It does go into gear and you can ride it but no matter what it just sounds dead and somtimes stalls. I havn't pulled the carb out/apart. What can i do to fix this?
Well you can do the idle and maybe fiddle with the mixture screw right on the carb will be a screw and idle screw you need to turn this in 1/4 of a turn at a time with the bike running until it idle ok and the mixture screw you simply just fiddle with this turn it all the way in and unscrew it 2 turn and try this get back to me if not ok 
did you try both buddy and what size jets do you have in there get back to me
ok buddy the only thing i can thing off at the moment is the clip inside is too high or low put this on the middle position try this and gte back to me
HI BUDDY TRY THIS PICTURE GET BACK TO ME IF NEED ANOTHERÂ 
no buddy inspect seal on the inlet manifold and on the piston cap on the carb also clean air filter and put a fuel filter in the fuel pipe which will allow dirt to be filtered get back to me bud
ok buddy no probz im always here just ask me if you need help
yes buddy try blowing the jets with compressed air also tyr fiddling with that mixture screw again

yea man I've tryed to do this, it makes no difference.
hey ..yea man i tryed both made no difference. and im not sure what jets are in there.. im guessing whatever the stock one for that bike is?
ok man thanks ...if you think of anything else please post it.. I will do this sometime through the week as i have work for the next 4 days (hoping to get home early tomorrow) ..Im going to check out the float also because it seems like not enough fuel is getting through to the carb without the choke. Like i said it only idols with the choke on which i guess is forcing more fuel through to burn. So yeah i will check this out also.. thanks for your help so far buddy :)
hey would you be able to give me a link to a carb manual for this model (1984) ...or a pic with labels and all on it?
hey mate. sorry to be a pain in the ass ..lol but would you be able to post another pic? cheers
another diagram please. like a labled one if you could?
hey mate. I finally got around to doing the carbs and cleaning them out. There was so much shit in there and both floats were stuck. Ahwell that bits all good now but it still seems to rev high and low.. I played with the idol screw and it made no dif. It sounds like its sucking in way to much air. Could this still be a prob with the air mixture screw? Get back to me,
Cheers.
Hey man. Yeah the bike has a fuel filter already i will have a look at the seal later on tonight. The air filter is clean as i had a look last night.
hey buddy.. I tightened up all the screws and done what u said around the carb/pistions... it made a little difference so i played with the air mixture again and by the looks she is all good!... Dad said that this bike always would rev high then u could ride/rev it and it would calm down ...and it did! it idols fine! im taking her for a test run tomorrow hopfully she is all good! thanks heaps for your help buddy! *VERY HELPFUL RATING*
Hey mate.. took her 4 a ride and sometimes shes good and she flys then others she stalls (starts first kick again tho) and sounds dead in the top end of a gear... I think i still need to clean the carbs out as i just did a rough job haha.. Do u think i should have a look at the jets aswell? cheers
