Just stripped the motor, crank is partially seized. New rod and it should be good to go.

Video - https://www.youtube.com/watch?v=AuJawMs8UqY&feature=youtu.be On idle the motor sounds normal but once the throttle is opened it makes a loud noise, it sounds top end but I've had a quick look and can't see anything obvious. Bike has a manual ... more »

2018 250f, no idea on history of bike.  1-5 gear works fine, selects, holds and runs smooth. 6th gear is selectable however makes a horrible noise (not crunching/locking up) and will rev as if you're in neutral. I have attached a video below where the ... more »

Hi Steve, I don't remember all of the gritty details but I know the solution was replacing the regulator and the CDI. I purchased the regulator first thinking it would be that however it didn't fix it and the issue continued so I purchased a CDI but ... more »

BACK STORY: I purchased the bike as "only runs with high idle out". I removed the throttle body, cleaned injector, TPS was set at .47 I reset to .48 (tried .50, .55) still wouldn't idle, at this point it was running the same as when I purchased it. I ... more »

Today as I was out of ideas I had a lot more time on the bike just testing around the yard. Some things I found: If I go from 10% throttle > 100% it pulls like a train, perfectly fine If I go from 100% throttle > 0% then around 30% of the throttle ... more »

I don't have the tools to check the fuel pressure unfortunately, I did look at the spray pattern, not really sure what good looks like but it looks OK to me? I can try to record it tomorrow maybe. I have access to a fuel tank (+pump) from a rmz 250 2012, ... more »

How do you recommend I clean the injector? I hooked it up to a 9v battery and blew some carb cleaner through and soaked it for a while in carb cleaner already. Is it worth putting some fresh gas in with some sort of injector cleaning and running it through? ... more »

My wires weren't touching the TPS terminals properly, sorted that and set it to around .625 and it now idles!!!! The bike now starts and idles however it still isn't being fueled properly, if I open the throttle slowly and close it slowly it is fine ... more »

Does anyone know why my TPS unit would now be reading 4.5v???! I am using the same power source as before that still reads 5v.

Hey! I didn't see a screen attached to the pump, I replaced the fuel filter itself.

I think the fuel in the oil is a common CRF problem, especially given the bike has had this problem for 6 months with the previous owner and he spent countless hours trying to diagnose it, I will be checking the oil again tomorrow though to see if the ... more »

Picked up the bike cheap, would only start with high idle pulled out, if high idle is turned off but you keep the revs up it will run. Checked the TPS, it was at 0.469. I tried 0.5 and 0.55 without improvement Replaced the very dirty fuel filter with ... more »

It was advertised as a TM 125 2003 needing a new piston... When I viewed it this is what I found. It was kept in a shed for the past 2-3 years and this is the result. I am going to part it out once I have a good idea of what year it is.

I have attached a pic below, the frame has been powder coated, I believe it's around 2001 but not sure how to know exactly? I am tempted to scratch back the coating but don't want to make it look sketchy.

Yeah the bike only has one fuse I believe and it's fine, I have tried swapping that out too.
