November 22, 201510 yr Hi, I've just bought a 2016 300cc and I was wondering what the mixture screw turns should be so its set right for me its a kelhin flat slide carb on it
November 23, 201510 yr The Kiehin is a fairly sensitive carb, thus there is no "perfect " setting as it will vary on the day based upon temps, baro and such. Normal range between 1/2 and 1.5 turns out. Set for best idle and response off idle. Colder days require less air(screw "in")due to higher air density for a given jet size. About 1/8 turn on the screw can make a difference. A good ear helps! Edited November 23, 201510 yr by copemech
November 23, 201510 yr The 2016 probably needs to be re jetted from the factory settings for uk unleaded, id try 128 main 44 pilot and 3 slide. From memory.
November 23, 201510 yr Hi i was just wonder what is you opinion on the new sherco and what is the 300 like ive tried to 250. I am worried about getting 250 as i think it wouldnt be powerful enought as a 300 would be easy to get up very steep mounds. I ride a 2011 290 sherco and i think the power is great many thanks
November 23, 201510 yr Author I was going to get a 250 but I tried a 300 at demo day, and thought it suited me more, they are easy to ride, good on power. if I was you I would go for a 300 but try it first
November 24, 201510 yr Yea thanks im just worried because im so used to my 290 that i might feel it wont be as good Many thanks
