Plug chop

[averysdad]

What's the best way to cut the threads of the plug without braking the white part Now I know y not a lot off people actually cut the spark plugs. I have wasted 2 plugs already tried cutting with a hand saw that didn't work. Tried it with a sawsall cut around it and wiggled the threads with pliers broke the white part, tried again with a grinder on a new plug broke the white part again. Any tips what's the best way to get the threads of without braking the white part? Now I only have 4 new plugs left

[yaegerb]

Have a dremel?

[averysdad]

No I don't need to get one them plugs are harder than I thought. Do you cut the threads or on top of the nut? From looking without cutting the plug it looks lean. How can a stock bike with stock jets at 100ft above sea level be lean? I need to cut the plug without f ing it up so I know for sure.

[onformula1]

I use a lathe.

Sounds like a air leak is causing the lean condition.

Can you post pic of the spark plug?

[averysdad]

I don't even have a dremel so no lathe as well lol. Already did a pressure test and also spread half a can of carb cleaner around everywhere after I changed the reeds I didn't take a pic of the plug before I destroyed it.

[yaegerb]

Cut the threads at the base of the nut. Can you post a pic of the plug?

[averysdad]

Way to lean230533 stock everything pressure tested 230535 rebuilt carb. Warmed it up changed plug wot for about 1/4 mile killed it pulled clutch. What is the problem?? Stock bike stock jets EL 75 ft

[Jmoozy27]

What model machine? Stock as in bone stock?? No pipe, filter, eBay carb?

[averysdad]

84 250r original stock carb and pipe Moose carb rebuild kit and filter.

[Jmoozy27]

Did you use the jets from the moose kit or use the original jets? Sometimes the kit are generic and don't meet oem specs. If you used the jet from the kit, switch them back to the original if possible. How does the trike run in general? What does the old plug look like from it warming up and riding around. When jetting my bikes and trikes I like to go for about a 3-5 mile ride trying not to idle too much if possible. Get back, kill it fast, check the plug. Just to make sure that I'm good across the board before I start checking individual circuits. Feel the performance, then look for it.

[averysdad]

I put the new jets in from the kit the original jets are plugged up all the numbers were the same.

The old plug looks black but it's really old

[yaegerb]

So WOT plug chop is showing you main jet only. stock main jet? You are using aftermarket reeds right? What size is your new main jet? New filter? Airbox lid on?

[averysdad]

130 stock main from rebuild kit New moose filter air box lids on. O ya I have the power reeds the directions said they would make it run rich?

[Jmoozy27]

I put the new jets in from the kit the original jets are plugged up all the numbers were the same.

Not a big fan of aftermarket jets. Moose jets are not the same because they have the same number. Order a 132,135,138, and a 140. You should be able to find a reputable bike shop near you with some jets. Surely in Houston.

[yaegerb]

No, you have to jet richer for the reeds, they don't make it richer. I would go up 1 on the main and drop your needle clip 1, pilot should be fine where it is.

[averysdad]

What you are saying makes sense now that I think about it the power reeds let more air in so I need more gas bigger jet.

But the paper says rich and to go down 1jet size why is this? 230549

[yaegerb]

That's interesting. How is the bike running overall? I would still increase 1 size. That plug looks a little lean.

[averysdad]

It was running good as far as I can tell just seemed hot that's why I did the plug chop.

I put the original jets back in they looked clean and set the float height it was off now 230552it's running like trailprotrailprotrailprotrailpro lol didn't have time to do a plug chop run.

So now that the float is right I need to put the moose jets back in if that don't work I need bigger jets.

Maybe some one can tell us about the messed up reed directions? If the reeds let more air in y would they say jet down

[Jmoozy27]

If it idles like crap with the original jets then the pilot is likely clogged. Try putting the moose pilot in and keeping the original main. Get more main jets as Brennan suggested. One size up should work but every motor is different. Those pilots are very small and get clogged easier and more frequently.

[yaegerb]

Go here and get some genuine Keihin pilot and main jets for that carb. I would get stock and a couple sizes above and below for both the pilot and main.

[nicker71]

I just installed a moose carb kit on my 81 250r. It had the same 83-84 250r carb as yours, aftermarket reeds, open airbox, but was completely stock everywhere else. It's ran fine with it and had a much darker plug that what your photos looked like. Just fyi.

Sounds to me that your float was causing the lean condition. I think your moose jets are fine

[averysdad]

Ya now that I have the float set right I'll put the moose jets back in and try that.

When I read the directions with the reeds they said it would be rich and I assumed could take the air box lid off to lean it back out.

Nicker thanks for your input. you run stock jets with your air box lid off? What reeds do you have? I have boyesen power reeds.

It's raining here now when I can I'm going to but the moose jets back in and do a chop.

[Dirtcrasher]

I've been using these guys for years. http://www.ebay.com/itm/10-main-jet-120-138-for-PWK-type-Carburetor-Keihin-Stage6-Polini-/331717401151?hash=item4d3be5da3f:g:4EIAAOSwnipWVd9 c

I can't find "made in China" anywhere. :lol:

They seem to measure up and fit great. They react to changes.

I must have 10 or more sets for every carburetor I own......

EDIT - Found these as well, http://www.drowsports.com/koso-pwk-carburetor-main-jets-122-145, - KOSO is what the other link gives you.

[averysdad]

Well I tried to drilling the jet out that wasn't a good idea doesn't run at all now idled good that's it lol

So now I'm waiting on jets.

[yaegerb]

Yes, I never recommend drilling jets. The cost of new jets is well under the price of all the Advil that you will need when it doesn't run correctly after drilling.

[averysdad]

Could the problem be that I'm mixing the gas at 32:1 and not 20:1 ?

Also I have a bit of the black goo coming from pipe don't seem like an exhaust leak no smoke or back fire just the goo.
Could this be the problem?

I may as well take the air box lid off if I'm going to buy jets. What size will I need for that?

I would just like to buy 2 mains and one pilot if possible $7 don't sound like a lot but if I buy 10 it adds up.I may get the jets dirt crasher suggested 10 for $20 then I'll need to buy more slow jets any way.

The bike doesn't idle up even if I turn the air screw all the way out. So I need a bigger pilot right?

[yaegerb]

Not at all, matter of fact I would run 36:1

Also I have a bit of the black goo coming from pipe don't seem like an exhaust leak no smoke or back fire just the goo.

No, this is typical.

Why are you wanting to take the airbox lid off?

If idle doesn't increase then pilot is too big.

Other answers in the box above.

[averysdad]

It seems to run better and sound better with the lid off. Is this not a good idea? I don't plan on putting it in the mud or water.

[yaegerb]

You can run without a lid, I would run an outer wears on your filter. You will need to rejet pilot/main and re-clip needle.

[Dirtcrasher]

So now I'm waiting on jets.

Ye sir, I double that vote. NEVER drill jets unless you have a #80 set and no other options.....

[averysdad]

Dirt crasher The first link you posted is the exact jet kit I need for my 84 250r stock carb just want to make sure ?

I see that company also sells pilot jet kits just not sure what one I need if you have time can you post a link to the slow jet kit I need?

I'm still trying to figure out why my stock bike with no air leaks runs lean with stock jets at EL 100
And why the directions with the reeds said to jet down

[averysdad]

Anyone know

[yaegerb]

how does it run if you pull the choke and run it around? Does it bog or sputter?

[Jmoozy27]

Because every machine is different and a reed manufacturer doesn't tune bikes, you do. Elevation is only one of the many factors that determine how a motor will run. Jet kits suck, buy a grip of jets and start tuning. Call motorcycle shops around your area and find one that has multiple jets for sale. It will save you time, money, and heartache in the long run.

[averysdad]

From what I remember from a couple times I accidentally left the choke on it would sputters .

I have asked the bike shop in my little town they have to order the jets tomorrow I'll call shops around Houston.

So I may cause my self more headaches buying the ones dirt crasher posted?

I am sure the ones DC posted are fine. They are likely the generic versions of the Keihin mains. I always use OEM Keihin jets so I know they are correct and I can eliminate any jet orifice quality issues from a future diagnosis. If you are on a budget then go for it.

If you are certain it is sputtering then you shouldn't be too lean. Double check to ensure your choke is richening your whole carb. Pull the choke out and ride it around. If it's sputtering then you arent WAY to lean.

[averysdad]

I got my oem jets in today from jets r us. Went from a 130 to a 132 no real change when I cut the plug I'll try the next one up when it stops raining. I don't understand why the plugs not showing richer when I changed the jet?

If I leave the choke on after I crank it up it smokes like crazy from between the pipe and head and also out the end of the silencer and bogs.

I am running the bike wot in 5th for a couple hundred feet hitting the kill switch pulling the clutch and letting of the gas all at the same time that's how you do it right?

[Mackus84]

Sounds like you need a new exhaust gasket and torque the pipe down to proper spec

[yaegerb]

Not much of a ring there to look at. Put a fresh plug in and ride it around for a bit (hour or so) through all the gears and all speeds. Don't cut the threads off and take a pic of the plug from the top looking down at the electrode and a couple from the sides.

[averysdad]

What do you mean torque the pipe down? It has 2 springs on it I have the bolts that hold the pipe to the frame tight. I may need a gasket where do I buy one can't find it? I bought a tube of red rtv but couldn't bring my self to do it yet lol.

[yaegerb]

Don't use rtv, buy a new o-ring for the pipe

I assume you have a stock pipe?

If so, here is the part number: 18352-961-010

Call around to a couple dealers in your area and see if they have a Honda nationwide database to look up stock in other states.

[averysdad]

Will do I have cut $20 worth the plugs and haven't got anywhere. I have 1 new plug left I think lol. I took the fule value off looks clean has a small white tube on it that's clean. gas flows good when draining the tank.

[averysdad]

Ya I have a stock pipe thanks I looked for that every where on the net didn't think to try the dealer

Oh sorry, for some reason i was thinking it had bolts holding it down like 4 strokes. Sorry for the mistaken assumption Sir. Im not very well versed in 2 strokes. Didnt realize they all have the spring get up until i just read about it lol.

[averysdad]

Had a run in with the law so I didn't get to rid it very long today. I forget it was Wednesday when I rounded the corner seen a couple people in the church parking lot and a cop car but no cop. Riding real slow I went down a ways and turned around by that time the cop was standing by his car flagging me down. He said how would you like me to take that you better get it of the black top I replied yes sir.

I know what I was doing was against the law and he let me go I'm think full for that. I live on a county rd golf carts, gators, rzrs, tractors, dirt bikes , drag cars, off road trucks, are on my road all the time. I bet 2 or 3 cars in the church parking lot had expired tags and inspection. He was not on duty he was at church he could have just minded his own business. I bet he thinks he saved my life and the lives of others lol.

I was never planing to ride on the road a lot and ruin my new tires just trying to tune my bike.

[averysdad]

This is after 15 20 min looks rich to me? Some have flash on some don't.
231969231970231971231972

This is my plug chop looks lean?
231973 same jets in all pics 132 main 50 small?

[Jmoozy27]

Definitely rich on your idle, probably lean on main

[averysdad]

this is a really crappy video taken with my I phone in my shirt pocket.
I don't know if y'all can tell how it's running? If you can stand to watch the video. The first part is where I forgot to choke it and the last part is pulling the choke to show how it runs with the choke on.

https://youtu.be/685BxhBQ4RQ

[yaegerb]

I would say you are rich enough. Leave main alone and move needle clip down 1. And get some grips! :)

[averysdad]

Move clip down raising middle up right?

Ya I need new grips a better camera and more practice riding it.

Now I can move on from the hole cutting plugs up thing for now.

[averysdad]

I may try 1 more size up on the main and see how it runs later for now I'm tired of taking the carb of and cutting plugs.

It does seem to sputter around 1/4 to half throttle I'll see how it is after I move the needle.

3,4,5 seem to pull pretty hard something seems off with 1st and 2nd. Mostly 2nd.

[yaegerb]

Oops, I told you the wrong direction. Move it up 1 clip or lean the needle. See if that clears up your bog.
