2003 polaris trailblazer 400 - came with a few extras ,
hsp clutch kit , v-force reeds , full dg exaust , .


my biggest problems right now is that there is a the big delay between letting off the gas and the engine speed actually slowing down . sometimes but not always this will create a engine brake type of feeling .also studders at wide open throttle . i could use some new ideas because i have wasted plenty of time and $$$ thinking it was just the clutches needing to be rebuilt . as far as i know the jets are stock but i will be checking that later today when i clean the carb up . it was running great last year so can anyone tell me what i should run for a jet or is the stock one ok?

 

hey i have a trailblazer 250 with bored out piston and hsp pipe and i went to put on a minkuni 35mm tmx flatside and it was running way too rich and when i hit the throttle in gear it would just puts along i beleive that the main jet is too big i checked and its was a 340 so i am going to change it to a 210 my stock carb has a 155 so its still a jump i will let you know what that does for me and why dont you check to see what size your main jet is later

 

You need to start with a 270 main jet and go down until it runs smooth on topend then check the plug for a nice tanto brown color.
The HSP clutch kit has a high engagement so learn to live with it.You get used to it quickly.I would also ditch the DG exhaust and get the HSP that matches the clutch kit.
