Hello folks! Even though I had promised myself not to start tinkering with my 426 -01 until I had sold the XR600, I cold not stop myself yesterday. I soooo just wanted to take a look at the AP squirt and the airbox lid (as that is the easiest mod). Yepp, the squirt duration would make Peter North green with envy. I probably drownd the carb with fuel and will have a mother of time getting the bike started later on. But it was worth it - now I know I will have to do the BK mod a.s.a.p. Imagine the power of TT when people start modifying the carb before they have ridden it! I bought my 426 slightly used and only drove it for 150-200 yards to check that the tran´s ok and have not even started it since - waiting for the wether to improve (spring to arrive) and sell the old thumper. Airbox lid, is the mod to remove the entire lid? or just the small lid, with the snorkel thingy? the filter looks kind of exposed without any lid on. Will fuelscrew adjustment be enough when removeing the lid, or do I have to start with the jetting for that mod alone (hope not)? Took a look at the linkage, it will be a pain to dissasemble that, and the steering beerings, just for adding some grease! that should already be there (from the factory) . Oh well, time spent in the garage, is time well spent - I suppose. I will keep You all posted on the developments.
