r/Dirtbike_Help

Just wanna know if ths is still good for a while.

The bike is a 2014 beta 520 RS. It overheated and the engine locked up while I was riding. A few hours later, it fired right up and I loaded it into the truck. I didn’t run the engine any more than that because I wanted to avoid further damage. I used a borescope to take pictures of the cylinder wall and piston. Is this going to require a re-coating of the cylinder?

The plastic gear in my ktm 350sxf went out and my head and cams got damaged wondering if its fixable

Salve a tutti, ho da qualche mese acquistato una suzuki rmz 250, ho fatto il cambio pastiglie in autonomia ma forse qualcosa è andato storto. Ora la moto fa questo rumore quando è in movimento. Cosa può essere? Ho visto che la pastiglia ha in po di gioco è quello? come risolvo?

CRF450R 2016
I’ve taken the tensioner off, slid the bearing to the side. It’s as if the chain isn’t long enough to allow the chain side of the camshaft to lift up enough to push the bearing back into its seat.

Any ideas on what I’m doing wrong??

My electric start isn’t working and I think this is an intake sensor that is not connected but it could also be a tip over sensor (likely not though because I’m pretty sure my tip over sensor is under gas tank and has label that says up)

This sensor was near the battery area of my bike and was likely disconnected by previous owner

Hey guys! I got this 09 ktm 250 xcf and I have a problem. So when I'm putting the head back onto the motor it seems like there's a indent as if a oring sits on one of the dowel pins. I included a picture that I'm using for reference but in my head gasket set there's a random oring that I can't find anywhere to put. Has anyone rebuilt one of these 09 250s? I'm stuck and need help 😫

It's a template 250cc from Amazon and I haven't adjusted my valves does it sound about like it should?

Hey i have a few questions, so I have been riding 4 strokes for all the time ive ridden dirtbikes, I started on a 90, then a 125 now a 140 kayo, (Chinese slop) yet there really reliable, but now im wanting to chase something different, ive looked and decided to get a 2001 yz125 thats been rebuilt top end i snagged a crazy deal only 2500 AUD, so i hope it is good, Im just more so worried that since its my first big bike that it will have too much power, or even maybe not enough, I havent ridden a track before and dont exaclty plan too, maybe in the future tho, ill ride forestry and trails alot so it will get powerband alot, but im worried it wont be fast enough, like I want to do wheelies going 40 kmph (allegedly) but also to be able to go 60kmph without fully fully pinning it like I do on my 140, )I know the 125 is way more powerful) I just am hoping someone that either has alot of knowledge or has owned one of these machines can help me! And please let me know if this bike looks good, i have mixed feelings about how it looks 😭
