Default 2018 Yamaha EFI Quiet Tec losing Acceleration

My cart is suddenly losing acceleration, so bad, that it can hardly make it up the incline coming out of a tunnel. I am having the same issue when traveling on MMP's that have any kind of an uphill portion.

Purchased from Carts and Clubs, who I have called and gotten a service app, but not for another week.

Wondering if any one might have any suggestions Thx

I would start by checking the condition and tension of the drive belt.

Definitely the spark arrestor. On the 2018 it’s accessed through the bottom plate under the motor.

We had the same issue. Got so bad it would barely run and had to have the thing hauled home by Kartaide! You have to pull the bottom cover of which is 4 bolts. The exhaust pipe is covered by a rubber sleeve on the drivers side that comes through the plastic cover and has some tabs you have to pull aside to get the cover off. Once the cover is off you can slide the rubber boot off and see the exhaust pipe. We had someone who used a drill to remove the steel wool like substance that makes up the arrestor. Problem solved. It can be a DYI if your able.

Default I agree with the spark arrester

I just had my cart's yearly service done and the tech warned me about the arrestor might become a problem giving the cart poor performance and the "fix" was to remove it;

My 2018 Yamaha Drive2 gas cart had this symptom just before the secondary clutch failed. It was most noticeable when going up a steep incline. At first there wasn't much sound, but just before failure it started making occasional clunking sounds. I purchased it from Carts and Clubs, and the guy who picked it up said they had seen a number of carts with this issue. It was covered by warranty 3.3 years after I purchased it because it was part of the powertrain.

Default Also secondary clutch on mine

2014 cart had same problem struggling uphills 2-3 years ago.
Carts and Clubs replaced secondary clutch. Caught it before it let go completely.
It is located at the drive belt pulley that is towards the back of the cart. Took a few quick minutes to replace in my driveway. Was a couple of hundred bucks total back then.

If you put the cart in neutral by putting the shift lever between F and R and try to rev the engine it may help identify what the problem is. If it struggles to rev up, then probably the Spark Arrestor. You can tell it's in neutral because it will be very easy to push the cart forward or back.

Same thing happened to my 2018 cart. Villages mechanic said it was defective muffler installed in factory and they were replacing every one as 1st year service came up. No problems since.

What did other places who work on golf carts say when you called them?
