Yamaha warrior/raptor 350 timing

[@jefferykaighin7039]

Thank you Brother! I was concerned until I watched your video!

[@jjtt6866]

You forgot to mention if it is on compression or intake cycle TDC when adjusting, rookies might break their atv. It needs to be on compression cycle otherwise it will not set right. people can see if is comp or intake cycle by testing if there is any play on exhaust and intake valve, if there is none it is wrong cycle to adjust, and you can get piston knocking / pinging and or spark plug late combustion of gas due to late/early timing that can destroy piston cause of excess stress and pressure to piston / piston rings .

I wish I still had this 4 wheeler to redo my video on this, I was new to the youtube tutorials and it's an awful video if I'm going to be honest lol glad you made a straight to the point video on it!

Hunter's Mechanics thank you

So I have a question I’m checking for top dead center have issues with running rich and eratic, burping so forth early combustion I assume, though I was top dead center I have my t dead on with line but the cam sprocket the line center but on the lower side of the sprocket not at the notch but lined up

[@Burkley429]

Okay I have an important question. I bought a 98 warrior that's been sitting since 2015 in the garage. Rebuild the carburetor got it to run idle's great but when I go to get on the throttle it will backfire and cut out. I checked the timing and when the bottom crank is at top dead center the top sprocket is just a little bit off of the marker on the side of the case so I adjusted it over one one link and it's off just a tiny bit probably a quarter of an inch. Do you know what would cause that?

[@michaeltaylor277]

If it’s off like a half a tooth that’s fine I would take the jets out and clean them out a new spark plug in it clean the air filter and put some fresh gas in it the carb could also need adjusted if you took it all apart and cleaned it

[@huntergraham8034]

On my warrior the exhaust side chain guide isn’t setting in the correct place so I can’t put the top sprocket on am I able to just wiggle it down in there or do I have to pull the flywheel and gears to get it in?

[@michaeltaylor277]

You might be able to get it in like that but your better off buying a cheap fly wheel puller on eBay for like 20 bucks and do it that way

[@huntergraham8034]

@@michaeltaylor277 ok that’s what I was assuming would be easier thank you.

[@Burkley429]

I have another question about my 98 warrior. The timing chain tensioner threads on the block are stripped. Should I buy a thread kit drill them out and rethread them? Or what is the best way to fix this issue?

[@michaeltaylor277]

I’d tap it to the next size up if not your going to need a new cylinder

[@ultragunner1585]

What blue beacon do you work at because I work at one too

[@danielfl.9347]

Do you have Any tips on repairs and typical maintanaince on a raptor 350?

[@michaeltaylor277]

regular oil and filter change air filters and greese everything you can

[@felixvalentin1618]

Theres no perfect point for me when i do the timing on it its damn close

[@tristensilva8448]

felix valentin mine it the same way

[@felixvalentin1618]

@@tristensilva8448 yeah as many times as i take it off and adjust tdc and line up the cam it still ends up being a tad bit off. I even rotated the engine 2x full cycles and end up the same each time.

[@AFondLaCaisse2024]

felix valentin stretched timing chain maybe?

[@Burkley429]

That's exactly the issue that I'm dealing with it's either a quarter of an inch off to the right and if I just at one link it's a quarter of an inch off to the left I'm trying to figure out why.

[@Burkley429]

So if it's a stretched timing chain and not perfectly on time would that cause the motor to backfire when I throttle it up?

[@thatawesomeman323]

So my 05 raptor 350 has an f not a t after it compresses is that not too dead center?

[@themiddleman7322]

It's usually a firing mark there should be a T and a F T for timing and honestly I have no clue how to set the firing mark

[@themiddleman7322]

so would I set my valves before or after doing the timing?

[@thatawesomeman323]

After timing while at tdc

[@cnote2774]

So when you put the cam shaft back on there’s no specific way to put it? I see the cam gear does but how about the shaft

[@michaeltaylor277]

Nope just goes right it you might have to turn it to get it in

[@cnote2774]

Thank you for the reply
