Just finished putting my sled back together and have a few questions before I fire it up. I cleaned and adjusted the carbs and was wondering where the fuel screws should be adjusted. Its a stock 98 srx with 1.146.3 2. 146.3 3. 148.8 main jets. Stock reccomendation is 1 1/8, is this a good place to start? I also just put on a bender silencer, do i need to rejet? I replaced the fuel and oil lines and bleed the oil pump, should i run pre- mix?

Is this the same as the 99? If so I'll be printing this out and getting everything perfect when I go through it.
Thanks for the info, now i can go put my carbs back in and get it started!!!

Open up your fuel screws to 1 1/4 turns or so and it will run better in the bottom end.
