Lots of updates due for the thread:
Farfle and I took the bike out for the last time this season at MAC track. Farfle was able to borrow a pair of leathers that fit him and was able to take the bike out on the track himself and did a good job of handling the bike.
We were also able to get some really important info about how the bike handles with different tires on. It's incredible how much of a difference it makes. We had been using these Dunlop racing tires, but the compound they are made of is too hard for Mk.4 to keep them warm except on super fast tracks like Laguna Seca. The result is that I spent a lot of time sliding out on the bike because the tires would cool down after a couple of laps around the track. We decided to try out the DOT tires that Farfle uses for commuting and found that while the rubber is better suited the profile of the tires didn't allow for as much leaning in the corners. One of the local supermoto guys we've gotten to know was awesome and donated a pair of rain tires to us and let us use his tire changing tools. These tires are super soft and have a profile that's in between the DOT tires and the Dunlops. The result was about 80-90% of what we would get out of the Dunlops, but all the time instead of for just the first couple of laps.
After the new tires were put on there was some chatter that was noticeable in the front, which was different because usually all of the problems came from the rear tire wanting to slide out. After talking with the supermoto guys we decided that the suspension setup might need to be changed. Farfle was able to take one of the gas bikes out for a few laps to see the difference in handling and suspension.
We came up with a lot of ideas about how to improve the suspension, which Farfle can detail later. All in all it was an excellent way to end the season.
