Thanks Pat for confirming what I've hear about the TOR's. Also thanks for your web site, its really helped me to get to where I am today, which is still a major improvement over the stock tune. Bike runs a lot stronger and now I'm down to the finer points. Nice that there is so much support from the Triumph community. Since, I don't want to replace the TOR's I may try the 128 mains after I get back from vacation and see how they work. Take care.
