Tire Went Flat Overnight
Hello all! I have been lurking on these forums for a couple of months and finally purchased a 2004 KLR 650 with 6,600 miles last week. The bike was owned by an older gentleman who was shifting his riding styles to more pavement riding. The bike was well maintained and has a Rick Mayor seat, crash bars, luggage rack with softbags, and the Doohickey upgrade. This is my first KLR 650, and for all intents and purposes I am brand new to working on motorcycles. I look forward to becoming an active member on these forums as it appears to be a great community!
Due to the age and low miles on the bike, I was a bit concerned about mechanical issues stemming from the bike sitting unused for so long such as dry rotted tires or a gummed up carb. However, the tires (Tubeless Avon Gripsters) appear to be in decent shape with lots of tread life/relatively little cracking and the bike fires right up and runs like a champ. After purchasing the bike I have logged about 100 miles, most of which were on the pavement, but some were off-road and some were two-up with no issues whatsoever
On Saturday we had some great weather here in southern Arizona and I felt like getting back to my limited high school motocross roots. I rode the bike pretty hard and quickly learned why the Gripsters are nicknamed "Slicksters" off-road. I rode the bike back to my house and everything seemed to be fine.
However, the next day I went to go take the short pavement ride to the gym and hopped on the bike to discover the rear tire had unexpectedly gone flat overnight. I inspected the tire and did not find any signs of damage, but did notice an unexpected noise from inside the tire such as something rolling around in the space between the tire and rim. I do not recall hearing that noise when inspecting the bike and rotating the rear tire up on the center stand before as I cleaned/lubed the chain and do not see any damage to the tire.
I spent pretty much all day Sunday searching the forum, YouTube, etc. trying to find information on the possible cause and solution, and initially ended up far more confused than I was when I started. I believe now I have a decent understanding of how these tube vs. tubeless tires work and feel prepared to take the tire off of the rim and inspect it or replace it if necessary. I just wanted to run a few questions past those of you who are more experienced as I did not locate this kind of scenario utilizing the search feature. I filled the tire up with air tonight and I cannot hear air leaking, but it's too late to conduct the soapy water test tonight and I will check the PSI again in the morning.
- Assuming the tire holds air overnight, how concerned should I be about the tire unexpectedly losing pressure?
- Any thoughts on what could be floating around the inside of the tire?
- These tires are in decent shape. If it is just a slow leak and goes flat again in the morning, what are your opinions on refilling the tire with air and utilizing the Ride-on tire sealant?
- Could the air have leaked out through a bad spoke? If so, do you recommend repairing or replacing?
- If it goes flat again, what would you do next in this situation?
Thanks in advance for the help all. If some of these questions seem very elementary, please take it easy on me. I have been amazed at how many hours I could spend reading about different types of tires, tubes, and rims and still feel so lost haha
