So I have an 89 Yamaha moto 4 250cc and when I ride it, itll get hot after like 10-15 mins and then will just die and turn off.
It's has new carb rebuild, new air filter, new battery, new spark plug so I don't think it's a crack in the spark plug
Can anyone help me?

Hey everybody,
My proficiency is with Hondas and Yamahas make me see RED!
This bike is my brother in law's, it has 1199 miles on it and went from running great to dead with no start. Every once and a while it will start and sputter for 2 seconds. It is extremely sporadic when it fires but never runs for longer than 3 seconds.
Here is where we sit:
Brand New Fully Charged battery
Carb was cleaned with air hose and carb cleaner then into the ultrasonic cleaner with Aircraft aluminum cleaner
New Shindy Carb kit (made in Japan version)
Cleaned out petcock and gas tank
New 93 Non Ethanol Gas
New Spark Plug
It gets a spark through the spark test light every time
Bluish white spark
When holding the spark plug 1/4" - 3/8" away from head it will jump and spark to the head
Good Compression
Here are the readings:
Pickup Coil 519 Ohms (range 459-561)
Charging Coil 266 Ohms (range 270-330)
Lighting Coil 0.700 (range 0.702-0.858)
Spark plug Cap 10.58 Ohms (10kohms
Ignition Coil Primary Coil 0.5 ohms (range 0.18-0.28 ohms)
Ignition Coil Secondary Coil 8.20 kOhms (range 6.32-9.48 kOhms)
Would y'all think stator and pick up coil, rectifier or CDI are the culprit?

I just saw a video on TikTok where some guy took the rear end off an ATV and bolted on a roto tiller in place of rear wheels. I wish i saved that video to post here....good thing it was 4 wheel drive...lol but, it seemed to work.
I'm not sure how he made it bolt on to the drive....

I generally use Non Ethynol fuel in all my small engines. I just got back from the gas station and that fuel has really increased in price since last year, I will continue to use it, even though its north of 1.00 a gallon more. That seems minor compared to cleaning and repairing carbs every year.
I was just curious as to what others are doing in regard to gas in their quads, i know a lot of the newer ones are fuel injected which shouldnt pose a problem, but i have had lots of problems with rust and jell forming in carbs when using ethynol fuel.

Hi, I am having issues with my TRX350D fuel pump. It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals. I have fitted a new pump, fuel cut-off relay and rectifier. Still nothing!! The pump runs when attached to a battery. The engine will start on the choke and the filter fills with fuel but it will not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine. Any ideas where to go from here would be very much appreciated!!
