Just got my first 84 250r my first 2 stroke. when it is in neutral with the clutch out it makes a knocking noise if I pull the clutch in the knocking stops only does this in neutral is this normal for 250r's ?

Also the clutch fills like its slipping It will barely pull the tire up I tried adjusting the cable that didn't help. Do I just need new friction plats or could it be something more? First seems ok but if I hit 2nd or 3rd and hammer on it makes a Wired sound if I baby it it's ok? I have a carb kit coming just need to know what clutch parts to buy

Time for some new plates and possibly a basket.

The clutch noise is normal.All my 250rs have that chattery sound both air and liquid cooled.

Thanks for the help i will post pics of the basket. if I ride it like this will it hurt any thing? every one wants to ride the legendary 250r

Depends on how about the plates are worn. I have seen pieces of them in a case before because they shattered from extreme wear.

all I could hear was the RPM's rising and falling with the clutch actuation. I have heard worse than that. Only way to be 100% is to disassemble and inspect.

I found the friction plates at bike bandit but I can't find the gasket. Where can I get the gasket? Hopefully the steel plats are good.

Thanks for the link. The manual shows that I only need to remove the clutch cover to change the clutch is that true? If so I only need the round gasket for the clutch cover. It's an 84 air cooled

yes, my fault, wrong part number. Right one is below. Its the gasket behind the round cover.

Rebuilt the carb today carb was clean except the main jet I replaced everything that was in the kit. Set the float level buy blowing in the carb I don't have a gauge. Helped a lot but still needs clutch I ordered one already the only problem is I set the air screw 1 1/2 turns out but for it to idle the idle screw has to be all the way in. I will try this tomorrow 229601 this is my compression cold 229602 this is my plug229603 any input is helpful I'm going to try the compression tester with the engine hot maybe it will go up.

Did you hold the throttle wide open when you took that comp test?

The plug looks a little rich.

For the air screw adjustment, start the bike and set idle relatively high. Then seat the screw and count number of turns out until bike is idling at its highest. Let us know how many turns out that is.

I assume stock carb and jets?

I had it wide open choke off/down but the engine was cold
A little rich may be good for me at this point it's my first 2 stroke and I don't want to go through piston.
Carb and jets are stock 50 and 130

i will report back about the air screw tomorrow air box has 4 or 5 ...1/8th holes in it very small holes maybe 1/16

sounds good. I will check back in tomorrow.

Warmed it up turned the idle screw in a bit more. Seated the air screw turned it out about 7 or 8 turns before the bike idled up just a bit screw was about to fall out? Reset the air screw to 1 1/2 turns out and it idles fine just the spring on the idle screw is under pressure lol .needle is on the 3rd grove

ok, so when you blip the throttle at 1-1/2 turns out does the bike come back to idle very quickly? Does it sound crisp or blubbery?

averysdad
03-27-2016, 02:40 PM
Yes it returns to idle almost instantly. Sounds crisp to me I will post a video when I get home. I just want to get the tuning right all the threads about going through Pistons and ceasing is kinda scary lol. The bike runs good just seems down on power. We will see when the clutch comes in. Until then I need all the help I can get with the tuning

Sounds good. Before you tear into the clutch I would do a pressure test just to be 100% sure all is well with your seals. Up to you.

I was afraid you would say that. I'm going to do the clutch first and hunt down the plugs for the pressure test. Do you think it could need reeds? I don't know any thing about reeds clutch seems to be getting worse.

Need to examine reeds. Post up some pics. If they are OEM I would think a new set would be a good idea.

According to the manual 128 psi is the service limit for compression. Hard to diagnose jetting with the compression that low though. If you're having to turn the air screw in all the way it sounds like your pilot is lean, or clogged.

As far as the rattling noise; you'll have to pull it apart, it sounds like something's broken. I know mine doesn't make much noise at all just idling. Did you check the transmission for oil?

What is up with the thumb throttle on there? It looks like you are pushing it half way in before the rpm changes. Make sure the slide is opening all the way at full throttle.

Bkm That's why I'm posting this is my first 250r and it don't have the power It should.just rebuilt carb with stock jets slide looks to be opening when looking in carb

Of course I cheeked the oil and changed it 229629 looked good to me

Well compression is low, that's the first place I would start.

averysdad

I know it's low and will need a rebuild soon but I'm going to ride it some first and learn more about 2 strokes that way I only have to put one top end on it. Will being a little low on compression make it not pull the tire up in 1st and 2nd gear?
I need to master the carb and clutch and tuning before I do a top end.

loganm
03-27-2016, 08:37 PM
Maybe. Are the tires spinning? Or does it sound like the motors spinning but not going anywhere?

I wouldn't shy away from doing a top end because of my fiasco. You already have a running bike, I bought a blown up basket case with no top end and have had to rebuild and tune the engine from scratch. I'd imagine your top end is just worn out.

Still sounds a little blubbery but it is falling back to idle nicely. I would set the air screw at 2 turns and leave it. I agree with BKM, somethings funky with that throttle. You may need a new spring in the slide or a new spring in the thumb throttle box.

averysdad
03-27-2016, 10:45 PM
The spring was kind of easy to hold when I changed the needle usually have more trouble. I will set the screw 2 turns out and check the cable. If the spring is weak I should still get full throttle right? Maybe bkm is right and I'm only getting half throttle. I don't know any thing about 2 strokes yet but it's like it won't stay in the power band comes on for a sec then gos off it try's to come on but don't 1/2 to 3/4 pulls harder than wot.

Yeah if you could easily compress that spring time to get a new one. Carb springs is my banshee and 250r are a PITA to hold and hook slides back onto. Also make sure the spring on your thumb throttle box is ok. I saw your tumb throttle jumping around. It looks loose. Should be good and tight.

This is the throttle 229684229685 looks like that tab should be in that hole and it's not. Any way that should not have any thing to do with the low on power problem I don't think. ran it with the lid off the air box and it came to life a bit more. But I want to run it with the air box on and the stock jets. I will take the reeds out this weekend and post pics. Been reading up and I think that's the problem. I'm going to figure out how to post a video of me riding it so y'all can see what's going on. How much power should it have? Maybe I'm expecting to much out of it. After hearing it's so much faster than a 200x get a 250r get a 250r lol

If it's running correctly, trust me you will know. I built a pretty mean 200x and it couldn't hold a candle to my stock 250r.

That's good to know. We will get it running right just takes time. Cheek reeds put in clutch new throttle pressure test top end.
