*Part 3 will be up this Saturday!*
I own the same big red and love it. I just found out today that the
Champion heat range number is: "8 is hotter than 7", i.e. the higher the number the hotter the plug runs. NGK however does it backwards, i.e. 7 is hotter than 8. Also the NGK DR8ES-L plug has a heat range half a point higher than 8. This is the meaning of the suffix -L. The DR8ES-L plug that your referred to in the youtube above can be interpreted as DR7.5ES. In other words hotter than DR8ES but not as hot as DR7ES. Your video was the best that I have seen on this subject and I have been watching for help on Big Red carburation for over a month. Great job, and professionially filmed.
hymersbees thanks a lot Hymmers! I try to be as thorouh as possible when explaining things!
every 100 hrs I change the oil. and clean the carb every 6months or when it acts up. and a spark pug when it doesn't start under 5 pulls !!! after 7 yrs it still runs like a dream !!!
Bro !! This is the most intelligent explanation of the Big Red carburetor I have seen !! I have two Big Red 250s , one 200 es , and a Yamaha 200. They all run , but I struggle when I take carbs apart to know which jet does what. ThankYou!!!! And the tip on sparkplugs..Spot On !! Fixed my problems.
Thank you!
Huge help! My carb started stumbling all of a sudden. This video definitely helped me take it off, clean it up and get it fixed up. Put it back together and runs like a champ! Thank you!
Rick H Thanks a lot! That's why I do it!
Don't forget to subscribe 👍
Thanks for your videos! I recently acquired a 85 250es that has sat for 5 years. You really helped me with tune up and tracking down an electrical issue!! I subscribed and will make an effort to view your advertisers! :)
Thanks for watching Jonk!
By far and away the best I've found on Big Red "how to" videos. Thanks. We still run one of these. We get many laughs from folks in their 15K side by sides. I guess it never occurs to them that in the 40k for the 4 wheel drive truck which never gets muddy, the 10k trailer to haul the 15k side by side all added together would put their Child through a two year RN Program at some college and does not matter. Being a poor person, I just don't know any better, I guess, than to run my little old Yota 4 wheel drive and Big Red out of the back of it, without incurring massive debt. In this country if you can afford to make the commercial and get it air time you can sell anything. Thanks again for a very well done video. It is saved to my Favorites now and I subbed. Peace to you and yours son.
Great job man! Very helpful!
Hi awesome carb detail I have 86 trx250 same bike one more wheel. Just wanted to mention you were right about champion plugsbut the higher number on NGK plugs the colder the plug.
Man, your vids are really well done!
Thanks for watching!
Great video.
Thanks for watching Joseph!
Too bad you had to pull the carb again to adjust the metering rod but as Frank Sinatra sang "That's Life". For any of your Eliminators the carburetor pressure pump is Stens part #705-020 with a list price of $192 Cdn which includes the sales tax but since Eliminator Performance has set up an account with them you got the $110 Cdn price. Presently Stens offers free shipping with orders of $150 Cdn or more which is a great savings over time.
where do the top 5/8 hose go for vent. One hose goes from crank case then has a T, lower hose goes down to vent . Top hose goes up behind carburetor then comes out under frame below front part of seat. I can smell gas fumes from it while its running. Does this top hose go somewhere? Fumes are stinking up my garage
Thanks
Is there supposed to be an o-ring and/or washer in with the spring on the air/fuel mixture screw?
Yep. And screwing in the mixture screw will make it leaner, not richer. Only 2 mistakes though.
To answer my own question, for the sake of future readers.
Yes, there is supposed to be an O-ring and washer on the air/fuel mixture screw, along with the spring.
The o-ring goes into the carburetor first, followed by the washer, then spring.
Or to make it easier to understand, slide the spring onto the needle first, then the washer, and lastly the o-ring.
@@hassandawudi4810 Right
Unscrewing the pilot screw leans it out??
He said it backwards
1986 big red 250, replaced battery, electric start has nothing. No clicking no anything. Headlight n neutral light turn on after the machine runs awhile when i use kick starter. Headlights do not turn on with new battery unless machine is running for some time???
What solution do u use in you’re ultra sonic cleaner?
I have a big red 250.. has spark. Plug is wet. Wont start. I can smell gas coming out of the 5/8 vaccum line that is under the seat that connects to the motor then T's off and goes up to my seat. I can also feel air coming out of the vaccum line when i try starting it. Help please. Had carb off 3 times
Would u care to do a video on a 1984 200es big red firing issue had a couple loose fire
I don't have one of those, this was a customers that I had to go over.
Probably coil pack or grounding on kill switch. Try putting electrical tape in between handle bar and kill switch sometimes they ground to the metal bar and cut spark!
Are the 4 stroke plugs the opposite of the 2 stroke plugs? Lower number is hotter Br8es is hotter than a br9es
NGK and Champion are different. Champion plugs are hotter the higher they are, and NGK are hotter the lower they are.
My 250 es drives fine for a bit but when I decelerate she dies on me any ideas
Mine doesn't have a spacer 🤔
Canadian eh?
Yessir!
My mid length carb jet seems to be blocked. I can not get my cleaner rod through it. I am assuming it should be open all the way through. Is my stupid self correct in that assumption????? HELP Thanks.
87 250 Big Red. Sorry. Great video has been much help. Thanks again.
@@ergot57 try using a compressor to blow it through, sometimes the holes are very small and you need to improvise
Ok will do. Just glad to know it should be open. How else could it work if it were not? Silly me. Thanks again.
