Umm, Bill, the quarter jr. estimate was for the last rear sprocket, not the current 52(?) tooth one. More teeth will result in a lower 60' time with that software. It isn't perfect, but it does quite good estimations with the information it gets!
Appreciate the adjustment to valve lash. Improving the bottom end has helped the 60' times! If you want to find .014 (or more) just advance the existing cam a little.
Your second round - was it later in the day with better air? I'm trying to understand why it went so much quicker than the previous passes. Improved weather conditions could help explain that.
Yes, the bike is responding to your adjustments. Congratulations on winning a round. Yes, this is supposed to be fun.
Dragracer - I'm here trying to help cut down the learning curve. Sam is coming over in November to drive that bike. Small tweaks to reduce the existing combination variations does help. There are limited opportunities for Bill to test between now and Valdosta. Is the tuning time better spent cutting the variations from .3 seconds to .25 seconds (quarter mile et's) with maximizing the existing combination or replacing the cam now and testing for a reduction from .3 second variations to around .1 second variations? There won't be enough time to properly do both. Does Sam want a .25 variation bike to race in November or a .1 second variation bike to race? If we test and tune to get a .25 variation with the current motor setup, what's the next step? Do we toss in the cam with little testing time before the big meet? The big picture for Sam is to have the most consistent bike possible. If we had the time, doing the exercise to refine what we have would be fine. I don't know why we would want to do that, but we could. The cam swap will improve the bottom end - improved bottom end will help to reduce variations- reduced variations make racing that bike more fun! Even after the cam swap there will be more small adjustments that can be done to improve the bike. The cam is a major change that needs seat time and data recorded to get comfortable with it. This is part time racing. I'm just trying to help reduce the learning curve. I'll buy the Cokes and listen to why we should have refined what we have at the expense of significantly reducing the variations. (if I'm there, still uncertain) Sam is spending a thousand pounds to compete. Check the exchange rate. If I were spending that kind of money, I would want the variations reduced as much as possible. In either case, it'll be OK. I'm supposed to be a help, not a hindrance to having fun. Having a consistent Hondamatic for Sam might even put a smile on my face....(for a moment at least)
Sam posted his opinion on this while I was typing my usual novel. Sorry for the length.
