So my dad bought this 01 Recon 250 semi automatic.
I have had to do a lot of work to get it to run good.
Biggest problem is this. ( I have had a bunch of diff quads but this one is a first)
She fires up perfectly all the time. Idles great
After she is warm and I put it in 1st, she leaps ahead and dies. I have read many posts about people having similar problems but not sure if it is the same as mine.
Idle seems good. Kick up and it is like it was shifted when at 1/4 throttle and then the key was turned off. Not like a lack of fuel thing or.... Its kinda hard to explain.

Then, if I start it with more throttle when I kick it into 1st, she will fly off the start and run perfect. It is only from neutral to 1st

Thanks all for any help

 

I suspect your centrifugal or one way clutch is sticking. Very rare for this to happen, and they usually either are, or are not, so for it to do it only when hot is odd. Are you sure the idle speed is set low enough to start with? Try lowering it until just above stalling. Only clutch test I can think of is, the bike should roll backwards if you push it, engine off, in first gear, but won't roll forwards, if it won't roll either way, a clutch is stuck.. This will only occur when the fault is on. The oil filter is also centrifugal, and is part of the centrifugal clutch so it gives you the opportunity to clean the debris out if you dismantle it to check the clutches.

 

So when doing that test
engine off, I put in first gear
Push backward - No go
Push forward - Also no go
I should add this does this cold or warm
I did an oil change and it seemed to shift a little better
Could the previous owner used some garbage non wet clutch oil?
If I go run the pee out of it with new oil, will it help free it up some?
Once it is going, it runs perfect.
I have never done clutch work and to be honest it kinda scares me.
I would however prefer to do my own work rather than give it to a mechanic as I like to know how to do this stuff myself.

 

The wrong oil (in theory) would make the clutches slip, not stick. As I wrote above, very rare for this to occur. Have you tried slowing the idle right down?

Removing the clutches is awkward on 250s as the clutch case is in front, at least there isn't a diff in the way like the 4WD models. I usually stand the bike on it's backside to do this job, and an air or electric impact wrench to slacken the clutch centre nuts is almost an essential item. You should have a special puller for the centrifugal clutch too, but I use a normal one with legs round the outside of the drum.

 

What if it will roll forward but not backwards? Mine has a new 1 way bearing and the centrifugal clutch will move counter clockwise but not clockwise.

 

If the bike will roll freely forwards but not backwards, you have put the one way clutch in the wrong way round. Take it out again, most have something written on them on one side, like "outside" so you shouldn't have got it wrong.

 

The one way clutch is performing as the manual says it should it will turn freely counter clockwise but not clockwise. I did have in backwards the first time I reassembled and yes it would shift ok but upon shutting it off it something inside the engine would continue to spin and come to a stop with a thunk.
When I rebuilt the change clutch I went into the inner casing where the transmission is I thought I got everything lined up correctly as it looked like it would only go together 1 way but am now thinking it may not be.

 

The 250 is a bit of a one off in Hondas, as the engine, although longtitudinal, is the opposite way round to all the other longtitudinal models, pull start on opposite side, output shaft also opposite, etc, I suspect the engine may revolve the opposite way too. Whichever, the clutch should lock when turned in the direction of crankshaft rotation. That thunk is quite common on bikes, doesn't seem to affect anything.
