Tried the TBS needles with no shims and at the same time removed the rest of the snorkels and installed a brand new stock paper filter (had a spare). The unit had about the same acceleration as before but the popping increased on deceleration (leaner). Noticed a problem when cruising at 1/3 throttle at 90 to 100kph the unit would hunt a bit and at times feel like it was going to quit. Pulling the choke helped get rid of the problem so it appeared to be lean. Plugs remained white. I guess the TBS needles did not richen up the mixture in the mid range enough to make up for the reduction in intake restriction with the 3 snorkels removed.
I installed the 130 mains tonight and left the TBS needles in with no shims and the unit is 100% better with no more hunting in the mid range. Acceleration is noticably better. Will drive it for a few more days then pull the plugs again. I may add a shim to the needles. It appears our long TORs have less restriction than stock TORs with baffles. I guess on Pat's calculator you could assume that our TORs with the packing around the center pipe are similar in restriction to baffled TORs with 2 baffles removed.
Here is the current config
130 mains, 42 pilots, TBS needles no shims, 3 turns on idle screws, AI removed, all snorkles removed from air box, new paper filter. I'm waiting until next summer before the Freak goes in. Colder weather is on the way and my missus also wants the hardwood floors installed, and the counter tops, and the.....
