hello every one im new but have a problem.

right i took the engine out and have put new gaskets on the engine.
put the engine back in the bike, timed it right and wont start.
i dont have a kick start so i have to bump it.
theres a strong spark and there is compression.
i also cleaned the carb and cleared the jets and i also cleaned out the tank and put new fuel in it.
the engine hasnt run in a good 3 years.
anyone got any ideas?:)

Ha ha bet its fun checking for spark on that without the kick starter. Do you know how much compresion there is? How far apart did you take the motor? Does the plug have gas on it after you try and bump start it? One last thing how does the air filter look?

im not sure how much compression there is, but i do know that there is loads because it locks up in 1st and 2nd when trying to bump.
i took the head off and that came apart for general inpection.
today when i was bumping it, it fired a few times i heared a pop or two.
i think i need to be towed then bump it:)

I have a few kickers around if you measure your shaft I can see if any of them will fit. That and I need to know about how tall it needs to be.

People do sometmes weld them on but I would never do it my self. I am pretty sure it would ruin the shaft and as you say the engine wont come apart. I wont charge much dont worry bout that not like the dollar is worth anything anymore any way lol.

Maybe you took the advancer apart and put the rotor back on 180 degrees off? Pat Orman.

Ya I guess most of us are but not all. I have ten or 11 xls from various years and lots of parts here and there I know I have a kicker from an 85 xl250 and a few from xl100's as well I just need to know how big your shaft is preferably in millimeters as I hate inches, why we cant be like the rest of the world and use the metric system is beyond me.

I found two that will fit one is silver its from the 70's the other is black pretty sure its mid 80's xl250 not poossitive tho. The black one comes out further when opened for kicking. I think the black one is gonna work better but I cant say for sure you want a pic? I can post one just let me know I will get you a shipping quote just give me an address I think 15 bucks plus shipping sounds fair.

Ok the black one is defenitly from the 80's as it is much more curved as the 80's rfvc engines had the big round stator/rotor area and it had to clear this.

my address.
75 lily hill road
bracknell
berkshire
England
postal code- RG12 2RY

A pic would be cool :]

i tried to bump start the xl again today and it fired a few times, could the timing still be out?
or do i need to keep trying to bump but for a longer period

The timing on these is generally either on or off. When you put your cam back in did you make sure it was lined up perfect? It can be easy to get it installed off by a tooth and then it wont start. This does have cdi and not points correct? Pat may be correct a lot of people do put the advance together 180 off but I dont think you bike has one but I may be wrong. If its just poppin and wont start I would bet the cam is off by a tooth or two that or you may need to push it down a bigger hill. I will get a pic up here in a sec and head to the post office I need to ride my bike today its gonna rain tommorow. On a side note my favorite band is touring europe The name is tiny vipers she will be in the uk 11/3-11/6 with damien jurado ha ha sorry I had to say that I never talk to anyone from the uk.

yep that kicky is the same as the one i had for my bike, they're so hard to get hold of hear i think.
im pretty sure the timing is spot on and the cdi has a little woodruff hey thing so it cant really go out of place i think.
i checked the valves, when the piston is at tdc, the valves were both closed and didnt move when the stator was wobbled - the manual said to try this to see if it was timed properly.
and the pilot jet, how should this be set up, because when i check the spark plug after bumping, it was black and wet

Is the advancer on the end of the cam? And you lined it up on the pin in cam? Correct? Ok, the rotor part of the advancer will come off the advancer and can be put back on 180 out. I'm not sure but I think your 85 is still triggered on the end of the cam not on the crank like later ones are. If the advancer is on the cam there are 2 o's on it, one is on the face of the rotor and one is on the advancer base. They should line up. If not, take the bolt out of the end of cam, pull the rotor off the advancer[pull out and rotate back and forth] turn it 180 and put it back on. Hold the spring loaded weights out a little and line the notches in the rotor up to tangs on weights, slide the rotor back on and put the bolt back in end of cam. Do the few pops you have gotten out of it sound like a fart out of the pipe? Usually do when they are 180 out. You've got good compression so it shouldn't be[hopefully] cam timing[valves usually get bent if that's off]. Pat Orman.

Good ole pat he really knows what he is talkin about. You say its like the kicker you used to have jus wonderin what happened to it? I have lost shifters but never a kicker its fallen off but I felt it and pulled over. Anyways They want 35 bucks for 1 to 2 weeks with insurance and 75 for 1-3 days with insurance. They will do it cheaper but it wont have insurance and you probably wouldnt get it. I have paypal if you like or you can just send me a money order but I can get it out sooner if you paypal it let me know what you want to do.

the advancer is on the end of the cam.
it is lined up to the pin in cam.
the o is lined up to the rotor. the cdi only has 1 pin that locks onto the cam shaft .
the pops kinda sound like went it starts up its makes a ploddy popping sound.
so your saying its not sparking at the right moment?

i lent my kicker to my sisters boyfriend for his tzr125, and he got rid of it with my kicker still on it.
i wasnt best pleased.
as for your kicker i'll have a think about it and i'll also hav a look around to see if there are any in england.
thanks for all your help guys.
ps. the pilot jet in the carb, how far should it be screwed in?
my spark plug is getting wet with fuel and is also black?

I dont know about your 125 but its 2 and 1/8 turns out and you adjust it from there and I thought I read but dont see it now that turnung it in will richen it and turning it out leans it. My carb has an air screw its located at the back of the carb by the airbox. I think if its in front of the carb by the engine it lets in gas and not air so you would have to screw it in to lean it and out to richen it. Not sure how the 125 was set up. Hope this helps. That sux about your kicker I would be pissed.

i'll hav a fiddle with the carb in the morning, i couldnt find the mixture screw on my carb, the only screw is on the bottom of the float bowl that drains it.
i'll hav a better look in the morning

That's what I'm thinking. Firing on ex stroke not compression. Good luck, Pat.

I would also take a look at what pat suggested he knows what he is talkin about. I once rode all the way home without the adjustment screw even in my carb it vibrated out and droped onto the engine where it sat untill I figured out it fell out so they can run with that not adjusted right just not very well.

Your welcome Max, and the carb is tough thing to clean especially those itty-bitty holes like pilot jets. The air/fuel adjustment for idle is probably a fuel screw on the bottom between the bowl and the spigot. In is leaner and out is richer. Pat.

Max, The parts fische on CMSNL shows there should be one. If it is missing you would be way rich on idle. The front of the float bowl kind of wraps around a boss the screw goes in. Pat.

He probably went here

http://www.bikebandit.com/houseofmotorcycles/honda-motorcycle-xl125s-1985/o/m9695

7 is the idle screw and ot looks like 10 is the mixture screw and as its on the side closest to the engine I think it lets more gas in so screw it in to lean it out a bit.
