450r carb ????s

[babiak400ex]

I just purchased a 450r carb for my 400 ex I know I need a throttle cable. I wasnt sure if I needed a new thumb throttle too. Then I was told it had the hrc modification as far as a needle and jet. The jet was a 185 I dont know if the is bigger or not than stock any way I konw it would be too big for my needs. I have a dyno jet kit in my stock 400ex carb and was wondering if any one knew if that kit would work in the 450 carb. I also have a dail a jet so that shold help me greatly with any jetting I will need It made a great difference on my stock carb that is for certain. Thanks for any advive ahead time.

the jets them self will work about the needle idk. I am running a dj 450r 175 in my stock carb.

you dont need a new thumb throttle..just the cable

i am also running a dj175 in mine

Your 400ex dynojets will work in the carb. I"m using them in my 450r carb.

What about the needle I just assumed they needed to match the jets would my dyno jet needle work with the 450 carb
