1987 Honda 250sx ATC

[boutselis]

Hello;

new here. I have not road for a very long time. I just purchased a 1987 honda 250sx and have been enjoying putting around on it. I have only owned it for a short time.

It seems to run good. it starts easy enough even though the choke does not work. takes about 4 or 5 kicks cold. then it goes right to a soft idol.

but I have noticed 2 problems.

When I have been riding and I stop and put it in neutral the rpm goes up pretty high. A little to high to pop it back into gear.

and if I take of in 1st without using the L1 it will bog down if I try to punch it. is this because you should always take off stating in the short L1 gear

or could there be any other problem.

I dont notice any smoke at all and it idols pretty soft so I didnt think the compression was low.

i would try cleaning the carb and putting a rebuild kit in or use some seaform in a few heavier than normal doses and see if it clears, you may have to adjust afterwards ... check to see if the throttle cable might be pulled or not in the proper location along the tank ...

is there an adjustable low jet on this thing?

Now that i think of it it kinda acts like my chainsaw does when the low jet is closed a little to much.

according to the manual there is a pilot adjusting screw. Even though it points to it I still havnt found it.

not sure if it will help in adjusting the L jet fuel flow or not.
