Drive chain slack

Recommended Posts

Slee

Hi all

 

I have a 2017 MTO7 Tracer. The manual I have states 30 to 35mm slack as pictured. My dealer was adamant it should be 40 to 45mm. Is the dealer right or go with the manual? 

 

Cheers

I loose chain isn't a bad thing if it isn't TOO LOOSE (real saggy) so I would think that somewhere in between 35 to 40 would be fine. Chains do loosen up gradually after they've been set so being a little on the loose side isn't going to hurt it. They say a loose chain is a fast chain so that's a good thing.

I'd trust a manual over a dealer.  Heck, I'd trust a rotten pile of dog poop over a dealer.

Maybe show the manual to the dealer.  I'd check with a mechanic who actually works on bikes for a living instead of the dealer.

Like @Beemersaid, a little loose is better than tight and splitting the difference won't hurt.  Just keep an eye and ear on it.

Yamaha designed the bike, and wrote the manual to those designs. The dealer should follow the manual, but I've yet to find one that does.

Flat-rate hours are a horrible system, and lead to shoddy repairs. Then you have the salesmen and service writers at dealerships that have likely never turned a wrench before claiming they know what's wrong/giving incorrect advice. 

The fz/mt likes a loose chain but you don't want it bouncing. Follow the manual.

Yamaha also designed the fuel guage, and look at how well that went 😛

What is wrong with the oil sight glass?

as Beemer says, the engine and bike performance overall is top notch. It has its flaws(as do all bikes) but you'll learn to live with them. Or make mods to lessen or eliminate  them. Or buy another bike.My gripe with the oil sight glass is when you fill the engine with oil after a oil and filter change, the glass is showing over filled. I use a Ratio-Rite to fill the engine with the amount of oil required by the owners manual so either the manual is wrong or the sight glass is in the wrong spot. Maybe the drain plug is in the wrong place. Only engineering knows for sure. The gas gauge is really bad. I generally put in around three gallons of gas after running all the bars off the screen and going into the reserve 40 miles or so. I'm too cautious to run the tank dry to find the true tank volume and as far as I can see, no forum members have done this to find true empty and actual tank capacity. Myself,I've accepted the bikes as it is  and just throwing my .02 in.

Its a mystery to me, why Yamaha did the gas gauge the way they did. The fuel sensor is just a variable resistor (~10 ohm full, ~215 ohm empty), they would only have to adjust the firmware of the dashboard. I  bet if you decrease the measured resistance by putting a little resistor / poti (around 2 kΩ ?) parallel to the green/white cable  coming from the fuel float sensor and ground, you could even readjust the fuel gauge by yourself.

 

Btw, the oil sight glass is perfect, with the bike on its center stand at a leveled surface the oil is close to the maximum - mark after adding 2.6L of 10w-40
