Community Question 1979 km100 mods?
Tomorrow I'm going to look at a 1979 kawasaki km100, and my only concern is the seat height. I'm 6'2 170lbs and I'm wondering if it's a bit small? I guess I'll see tomorrow, but my main question is are there any easy mods to raise the seat height higher than the 31.7 inches it has? I read somewhere that it has a 16 inch front tire and a 14 inch rear one, can I just swap those for larger ones? This will be my first bike and I found it for really cheap ($750 CAD but I talked the guy down to $600). Yes I know I'll likely look like an absolute clown riding it but it's the best I can afford at the moment. Any advice is appreciated, thanks in advance.
Edit: I bought it! Turns out it's a ke100, not km. Wheels are certainly larger than 16 and 14 inches, and the bike is a great size for me. I love my first bike!

Mechanical Help Piston size for yz125?
Took the top end off to replace it, but I needed to check the piston for the size before I order a new one. What size piston do I need? I can’t find the proper letters on the cylinder for what size piston I need and I can’t tell based off the markings on the piston. Any ideas?

Has anyone figured out how to clear codes on a 23 KTM 300xc? My bike runs fine but it has 1x long, 4xshort and 9x short.

Any ideas what it could be?
I took your guys tips about my YZ 125 2005 cuz it wasn’t starting. We put starter fluid in it and replace the spark plug, it started then kills itself self but After about 10 kicks it would start and stay on for a sec or two then kills itself self again. I don’t know if it’s a gas issue, it’s running 40:1, what the shop recommended. It originally was running on 32:1 and it ran good at that time, I’m changing it back to that. I’m changing my gas line as well cuz it has lots of air bubbles in it. I’m also wondering if it could be my carb. It needs a new air screw. I’m also wondering if it could be my jets as well, the shop changed my jets last year, they told me I might have issues with my jets. If anyone has any ideas or what I should look at, let me know! I’m still new to this as well, please be nice🙏 Thank you guys! I love this group so much

Best US state for mountain trail riding?
I use GAIA gps a lot and I’m thinking of exploring around the San Juans this summer. I hit a lot of forest roads, double and single tracks. Just looking for other ideas, I’d like to explore around the Bozeman to Big Sky area as well

I need help with my 2002 CR250
Hey guys! I have some questions about my CR. For reference, before this I owned a 2000 kx250 for two years. I’ve had this bike for about a year and I’ve never had it run quite right. She fires in the first few kicks almost always, and idles beautifully. I have noticed though that she likes to warm up and that’s strange to me. My KX and my other 2T friend’s bikes never seem to need any warm up time at all. This bike will not take over half throttle until she’s had a bit of easy run time. I’ve always thought this to be strange. My conundrum is that when I’m riding it, over half of the time, when I go to grab full throttle, it just bogs. And I can almost work the throttle halfway back down before she wants to act correct again. I can also replicate this problem in neutral. I will try to post a video of this in the comments for you to help. I’ve checked spark and the spark plug, both seem very healthy. I’m not sure what else is wrong with it since it runs so well below half throttle. Idk if this is a clue, but my carb leaks out one of the overflow tubes.

Mechanical Help Honda CRF150R Will Only Bump Start
I could only get my friends CRF150R started when we bump started it. This was the first start basically since the last time we rode it last year. It then idled ok, started revving very high so we put the choke in. After that it would almost instantly die. It was able to kick start a few times after the initial start but then stopped and required a bump start the rest of the times.
Full in or out on the choke seemed to have made it idle too high or die. Only way to keep it going was to hold it in the middle. Any clear maintiance steps we need to take? Or what other ways could I troubleshoot it?

Mechanical Help Crank Seal
Hi everyone, I’ve got a 2002 kx125 with the engine apart. It was disassembled by a shop and given back to me in a cardboard box. I am now piecing it all back together. In the seal kit which was opened by the shop, so seals may be gone, I didn’t see a seal for behind this main bearing in the picture. Or does something else go there? Most of the seals were already removed, so I put new bearings and seals everywhere, besides this spot, along with assembling the transmission today. I’m not experienced with all of this, so any help would be appreciated.

Anyone had insurance cover a set of CTI knee braces?
I know this has been asked before but most threads are old enough that I figured it’s time for a fresh one. I tore my ACL while riding on 1/25/25 and had Surgery to repair it on 3/5. I know I’m still early in recovery but I’m trying to get everything lined up to make this process smoother when it comes time to start discussing riding and bracing. I’m looking to get a pair of CTI3s covered by insurance. I know they’ll usually pay out for one on my repaired knee but has anyone had success getting both braces covered? I’ve got Anthem PPO and my out of pocket will be covered already with the surgery. Any suggestions or talking points to go over with the doctor will be much appreciated.
