How much should I increase my jet size after adding twin pipes?

That's why I pick up the one above on the weekend. 2000 mile. Should have another 3000 worry free miles. I may not ride my 2014 Summit 800,

I had a 700 with twin PSIs. all I did was mix 100 to 1 in tank and switch to good Shell sythetic mix oil checked the plugs a lot. drove it normally. it had about 8000 miles on it when sold it. still running today 10 yrs later with over 12,000 miles on it.

I ended up going from stock 185 to 195 PTO 205 Mag side. Runs awesome beautiful color. Very crisp. Changed pilots and needle as well. Runs very strong. Almost as good as my 2013 ETec 800!

I put twin SLPs on a 98 700 I had with 4500 miles. went up 1 jet size on mains, and added 1 oz of oil to each tank of gas after that. ran strong in mid range. but was too load for me.grandson loved it..! my friend has over 10,000 on it now, same motor.
