Yes, I am going to just straight up order a new fuel filter and plug as I should have done that straight up when I got the bike and did the oil change then. Especially as the bike was at sitting at sea level for two years being occasionally run and I brought it up to altitude.
The question of if I’m actually hitting redline or wind noise and such making it hard to hear, that is a good question. Yeah, I have serous wind noise with my helmet, and I’m sure the stock chain noise and stock tire noise adds to it.
For me redline is when I’m flat terrain and WOT and acceleration has topped out; the Speedo stops going up. That’s it, the engine can’t produce anymore hp.
Yesterday I had a long section of downhill from a stop that I could run through the gears at WOT. There is no question I’m getting all four gears. It shifts clearly into fourth and I get acceleration. Though I noticed I could get to 37 in 3rd, immediately went to 4th and it was already revving higher and still couldn’t get past 44mph this time.
I’m waiting until I have a stretch of a couple days where I can go in and swap tires/tubes, replace the chain (and fuel filter and plug, too) and install that reinforcing bracket on the shifter. Then I’ll know for certain the gearing and if the previous owners damaged the intervals when they bent the shifter. But I gotta wait until I have a good stretch of days where I don’t need to be anywhere and I can work on it.
