91coupemike Posted December 5, 2014 Report Share Posted December 5, 2014 Currently have a 138 and a 45 in my pwk 28s. It was jetted this way when i got it and after 5 gallons of gas i pulled the plugs and they looked fine, i havent had time to do a plug chop but it starts easy and seems to run fine. I do have to use choke to get it started if its below 45ish outside. Im at 600ft. stock motor with t5s, cool head 19cc, +4*,stock reeds, pwk 28 with pod filters, May buy some vf4s later on. What size jets should i use for around 20-30 degrees? Quote Link to comment Share on other sites More sharing options...
bluebanshee98 Posted December 5, 2014 Report Share Posted December 5, 2014 What was the temp outside after the 5 gallons of gas? Hypothetically speaking if it was dialed in 100% at say 70 degrees. Your gonna have to go up on the jets for colder weather for every 20 degrees if I'm not mistaken. When I jetted my buddy's bike I did it so it's good all year round. Was a little rich in the summer but colder weather it was fine Quote Link to comment Share on other sites More sharing options...
