Yeah that ethanol is rough on carbs.

Turns all green inside carb. Not using it anymore. Thanks Mr.

​@@bearknuckles100you have a link to the one you used? I have a 99 grizzly that's leaking and stopped running.

2003 jets are not adjustable, you have to change them out if needed. Altitude elevation and clutch springs usually dictate jet replacement. The only adjustments I know of on the carb is curb idle, throttle cable, and air/fuel. * that one is located on the bottom of the carb up in a hole. It’s should be a flathead style screw and it right past the float bowl and before the intake boot. Loosen your intake boot clamp on the carb side and also the clamp on the carb where the air box connects, you can turn you carb towards the side and maybe see the air/fuel adjustment screw. Be mindful the your choke cable, throttle cable and other hoses are still connected when and after doing this. I hope this helps out? 👍

It should screw into the same spot as before. Time stamp 6:23 on mine had a new screw connector, I removed the new one and just reused my original that was still connect to the end on my choke cable. Choke port for cable should be on the driver left side of the carb, just above where the thumb curb idle adjustment is located. ⚠️caution⚠️: That connector is plastic screwing into aluminum. You can easily damage those plastic threads when installing and tightening. Might wanna install by hand only. Just my advice.👍

It’s just a R2 tip. Got it years ago off of eBay. I have a couple videos posted before this one just on the exhaust tip on the channel. I haven’t made any adjustments to the oem and not any yet to the new aftermarket carb. Yes stock muffler.👍

@9:14 in the video the cable on the right is the throttle cable. The hose coming from the bottom region is the curb idle screw adjustment the comes around to the other side of the carb. Did this help?

@@MichaelEd thank you!!! Todays gas just eats these carbs if you let them sit.

@@Enjoytheinbetween yes Sir, 87 ethanol blend is straight garabage for these small engines with carbs. I run ethanol free as much as possible, if not 97 octane from the pump. No long term storage! Run your quad out of fuel when not in use has been the best way for me to help assure it’ll start up after it’s been stored or not used in months. Boats, lawnmowers, chainsaws, etc. Run’’‘em outta fuel if not use soon. 👍

Man I’m not exactly sure. Last time I went riding on trails, we ( as a group ) rode for several hours, including stops, and making it back to the beginning without running out of fuel. Running pretty low but never ran out.

What year the grizzly? Is it a 660?

I have the same issue

@@Doveproductions73 what year grizzly do you have?

@@MichaelEd mine is a 04, I actually got it figured out, the short tube on the top of the T goes up to a vacume port on the carborator and the long tube goes down to nothing and the other short tube goes up through the armor under the fuel tank

@@Doveproductions73can you show me somehow?

The wheels are ITP SS and the tires are Interco Reptile. Love the Reptile tires💚

The carb I purchased is no longer listed. I bought it about 2 years before this video. It was thirty-something dollars and I added an air filter that totaled out to be fifty-something dollars. I was looking at what is offered now and it looks like they include the air filter, fuel filter and even a new spark plug for about what I paid for but not with the extras like what offered. I know mine is not the Niche brand, but I think “in my own personal opinion” as long as it matches your carb you should be fine. I don’t know your grizzly spec, model, year. Mine is just the base 660 YFM660FR and the carb part number for mine is: 5KM-14901-10-00 You can cross reference with Yamaha and Partzilla to help make sure your getting the right carb when purchasing from Amazon or eBay. I am truly sorry that my purchase is no longer available to share. I hope my response is helpful. Thanks for commenting, and watching this video. I will make a new grizzly video soon, and I hope you’ll enjoy the next video even if it’s not grizzly related. Harry, Be sure and “Subscribe,” and I see ya on the next one.🤙

@@MichaelEd if you can buy a rebuild kit for the factory one

@@hodlr8489 yes you can.

I wish I had the link, I would. Amazon seller has removed the listing or doesn’t offer the item any longer. I can’t even find it in my list of previous purchases. 🤷‍♂️

I put some time, not a whole lot, but so far it fires up, idles, and runs pretty good. Yeah, that’s what I’m doing also. Rebuilding the oem, but until then this aftermarket was priced to good to to try. 👍

@@MichaelEd I appreciate the quick response. Yeah, I believe I'll do the same. Fuel seems to go bad quick these days with more ethanol in them. A backup wouldn't be a bad idea.

@@Tazman1966 for sure. Best practice I’ve found is shut off fuel and run it the carb outta gas. If you can get non ethanol fuel I would definitely do that. Ethanol blended fuel is garbage for anything other than daily driving vehicles. Thanks for commenting, more grizzly stuff soon. Until then I hope you enjoy my other videos. ✌️

I'm in the same spot... Thanks for the video.

@chrisc9802 thanks for watching!!👍
