RE:1987 Honda XL250R Advice Needed
(Date Posted:09/03/2009 07:12:15)
Hello RJ, welcome to oldrice.
Ya know, it kinda sounds like the float height adjustment could be off. If the tab that closes the needle valve is set too low, it could be letting the valve too far out of the seat assembly and getting cocked and wedged, not allowing it to move as a consequence.
I don't have the specs for the float height adjustment, but to get you in the ballpark, pull the carbs off, remove the float bowl and flip the carbs upside down. Set the float so it is parallel with the bottom of the carb/bowl mating surface. Just bend the tab that moves the valve to get the desired height.
Hope that makes sence.
As for the cold starting, these bikes come jetted very lean from the factory and because of that are very cold blooded. Several minutes of warm-up time are not uncommon, and are usually needed.

Hello thanks for the reply! I will re-check the float height. Would it be advantageous to go to a richer jet, I like the fuel economy, but haet the starting issues. Rob

Sure. You can go richer on the pilot and the main. The pilot's the one that will affect starting.

These floats are stupid mine did the same thing bike was a 350 but has the same carb setup. I ground a little bit away from the part the float tab was getting stuck on and it quit doing it. It sounds like its getting stuck on a different part in your carb as it wsa getting stuck on the part of the carb that the rod goes thru to hold the float in there on mine.

Thanks for all of your advice! I did re-adjust the float levels and they were a little low, haven't had any issues with it dying, and the enrichening circuit seems to be working better now.
I do have another question though... my turn signal relay is dead, and Honda wants almost $40 for one (the stock one has 2 terminals). I found a universal one with 3 terminals, and the factory wiring harness has an extra green wire thats runs over by the relay that is not used. My question is will a 3 wire relay work??? The universal relay is like $10 in comparison.
Thanks for your help!

Hmmm... I've never tried that. But you say there is an unused green wire close, and if I remember right, green wires are ground on the older Hondas. So... maybe the three wire universal needs a ground to work? If so, you have one right there. Guess it couldn't hurt to try? If it doesn't work, you're only out $10.00. But then if it doesn't work, you'll have to buy the $40.00 one, so you'll actually be out $50.00! LOL Good luck!

Guess can't hurt to try it out!
I still don't have the turn signals working, but I took the bike on a little road trip about 125 miles each way this weekend. The bike ran good but it did something weird on the way home...
I was cruising 2 lane highways about 60-65 and was about 80 miles into the ride home, and I caught a light and had to downshift and brake hard to stop, and after I stopped, the motor was making a whining noise like quite loud like a fan bearing in a car going bad sorta but not quite that loud, and it did this for a minute or two and then stopped. There was no power loss, but a few miles later it kinda sputtered a bit, and I noticed on the right side carb that there is a hole in the side of the carb that looked like it spit some black stuff out it got on the muffler and stuff I could see where it had spit it out. Any ideas what the heck she did? I thought maybe when I stopped suddenly maybe the oil pump lost prime for a minute or something? It was the weirdest thing. It sputtered a little bit at the next light and the whining was gone but I kept it running by burping the throttle and it never quit and then like cleaned itself out and was fine remainder of way home.
Any ideas?
Peace

Rob, I don't know where the crap came from but that hole goes nowhere. It's cast in the carb body for the fuel line, but since it's the secondary carb, no line goes there. The carb bodys themselves look like they can be used for either the primary or secondary carb, depending on the final machining.
You might have a look around the carb boots and make sure everything is still where it should be and tight.

I am thinking it may have come from the muffler where it clamps onto the header pipe now that I looked at it more. The bike did use some oil on the trip, as it was just over the bottom line on the stick. The bike doesn't leak any oil, so it must be burning it, but it doesn't smoke or anything so where is the oil going? The plug is not black, but light tan color looks good. Is it normal for these motors to use oil, maybe rings or valve seals or going?
I had to tighten the chain after my trip it was about 2 clicks on the adjuster too loose.
I figure thats probably normal after a road trip?
Thanks for your advice!

My xl500 made the squeally noise you refer to. Was it comming from the left side of your engine? On my 500 I had a bit of crud in the oil and had layed the bike on its side to do some clutch work didnt want to dump the oil. It worked its way into the fly wheel/stater area and got inbetween the where there isnt much clearnce and made the noise you describe I changed the oil and it never did it again may be whats wrong with yours.
