  1. Anyone planning to be at Vintage Motorcycle Days this weekend? I am going to be there on Saturday for the 600c race.
  2. I will go. Are you sure it isn’t cancelled? They are pretty bad at communicating their cancellations.
  3. If anyone is planning on being at Nelson tomorrow, I will be there practicing for my first ever WERA race. I will take any advice you are willing to give me.
  4. Yes, I created it on my phone so maybe I need to check an actual computer. It says it is full and gave me an option to get on a wait list.
  5. Just tried to sign up with N2 for the Nelson Ledges track day on 6/4 and it’s already full. That must be a popular place. I guess I am used to my local track never filling up (Mid-O).
  6. Any leathers with CE rated protection are good to start with but if you plan to do this a lot and you want really good stuff, the sky is the limit on what you spend. Mid-O rents leathers and renting a pair may help you get an idea of what size you need and what you like. When you go to your first track day you will see every brand of leather and some will be obvious that they are low cost. bare minimum crash protection....good tires. Frame slides are a topic of debate and some think they cause more damage or causes the bikes to flip. If it’s your first day, there isn’t much bike protection you need. Once you pick up pace, I would invest in track bodywork and something that protects your engine components. Some people ride to the track and ride back but I see a few bikes hit the dirt every track day so if it’s your only ride home, keep that in mind on the track. Also, you may be very tired after your track day. It’s a workout. Bring a chair to sit in, seems obvious but I have had a few days where I had to sit on my tailgate. Bring snack and plenty of water. If you have a shade tent, bring that.
  7. Don’t you only have to safety wire the oil drain, filter, and radiator cap? I think you may be a little off on this one, this feels like the right amount for intermediate. Their tech inspections seem on par with most other organizations. I honestly love mid-o and the staff but I wish their track was in better shape and they would stop canceling days. I can only really go on tuesdays and had purchased several certs last year only to have them cancel all Tuesdays. Now I am stuck finding babysitters and taking vacation days trying to fit them in before they expire. Also, if you have a cert that is good until next year and you sign up for a day only for it to get cancelled, they allow you to sign up for another track day but only until the end of the year. This takes away a full year of time to use your cert and leaves you little incentive to sign up early.
  8. Nice! I have been watching a lot of race videos on YouTube at Nelson Ledges trying to remember all the turns, get a feel for the line, and see where the turn in and braking points are. Your dash is the clearest on video.
  9. Race license? No. Race license course certificate? Yes I was afraid I may get stuck in Novice but that may be the best way to learn a new track. I’m not sure how much help with lines you would get in intermediate but at some other track day orgs, it seems the control riders are willing to show you. I just put Pirelli SC2 slicks on and am a little concerned the Novice group will not keep them hot enough to get good traction. I will send my info into N2 and see what they come back with. I have done about 20 track days and am Advanced at Mid-O and Intermediate with STT.
  10. I am signing up for my first WERA event at Nelson Ledges this year (6/6). I have never been to Nelson Ledges so I will probably be signing up for my first N2 track day (6/4) as well. Anyone plan to be there any of those days that I can bounce questions off of?
  11. Does anyone wear an airbag vest? I just picked up a Helite E GP-Air and am hoping it saves my butt if I need it. Not much online about wearing air vests on track.
  12. @TwiztedRabbit I agree with you that this is a type of cold tear and I know you are a very experienced racer/track rider but your explanation on tire pressure vs temperature doesn’t sound right or I am misinterpreting what you are saying. The only ways for a tire to independently get heat is by either absorption, flex, or friction. The larger your contact patch, the more absorption you will get from a hot track but the more you will lose from a cold track. This would be far offset by the flex in the carcass generating heat and this is the single biggest thing to generate an even heat throughout the carcass of the tire because it comes from the inside of the tire rather than the outside in. The more tire pressure you have, the less contact patch you have and the less you will absorb. The less pressure you have, the more your tire will flex which will generate heat. To some extent, the less pressure you have, the more contact patch you will have but there is a limit and when you hit it, your contact patch will get smaller because the carcass will bend between contact points in a concave shape drastically decreasing your contact. So what I am saying so far is, less pressure=more heat throughout the tire. The last way to get heat is friction. So long as you are not sliding, the reactive force of friction on the contact patch and the heat generated would be independent of tire pressure meaning you will generate the same amount of heat energy. The smaller the contact patch, the smaller area you have to absorb the same amount of heat (for example; If you add the same amount of energy to a soda can as you do a garbage can, one will feel noticeably cooler). Adding a significant amount of heat to a small area will heat it faster than it can be absorbed by the rest of the tire and will cause the contact patch to start to peel away (cold tear). Where I think your information may have come from is a very hot track. If the track is very hot, your tire may be absorbing heat faster than it can dissipate to stay at its ideal operating temperature. That would be a tricky situation to balance.
  13. @motocat12 Yes, this is exactly it. STG suggested staying above 21psi on the rear tire, which I did but what I am reading on the reddit you posted and several other locations is that this tire just cannot handle a high track pace which seems to be confirmed by Michelin. The tire is basically tearing itself apart at the connection point between the two compounds and looking exactly like a geometry tear. I found a few instances of this in some of Dave Mosses videos and he basically said the tire was not matched to the riders pace.
  14. In theory, when you lower the pressure, you increase the surface area of the tire on the ground and increase the heat generated into the carcass. It may also allow the carcass to flex more which generates heat. I suspected I had cold tear which is when the carcass is not hot enough so I lowered the pressure. The left side of my tire gives a better idea of what may be cold tear, geometry issue, too hard rebound setting, or all of the above. The right side of the tire is destroyed beyond telling what happened so I am mostly focused on the left side. Check out the Tire Wear Guide under “Track is Crack” it has a lot of good information to start.
  15. In the Dave Moss video you posted, my tire looks almost exactly like what is at 2:30 which he says is a geometry cold tear. One thing I do when I get off the bike after every session, is I put my hand on the tire to see how warm it is. If I can comfortably leave my hand on their, it is not up to temp. With this tire wear, I would put my hand on the tire and it barely felt warm. i think with hot tear, your tire carcass needs to be somewhere near 200 degrees.
