Hi all,
Working on a 98 tigershark TS770L with twin 38 mikunis for a buddy of mine. My question, and I have checked everywhere, is what is the factory needle and seat size, and spring color/pop off pressure? A 2.3 with a silver spring is currently installed, and I want to make sure I go back with the factory setup. My buddy bought it used, with a blown #2 cylinder, and he is installing a rebuilt 770 from SBT. I do not know the history of the ski, or engine, or why the piston seized. I figure the stock settings and parts will get him up and going, at least with the carbs. BTW, never worked on a TS before, I'm a big Yamaha guy.
