i am rejetting and the main jet is a no.98 and is 7 mm tall i want 2 use a no.100 or 102 do i have to get a 7mm or does the height matter?

is it a 185s? i got a 100 from my dealer and it didnt fit..i think the threads were like to big..it went in only about 1/4 turn..when i find the receipt im takin it back to get a different one..im not sure what trailprotrailpro talking about in the length

[84trx200]

nope its a 200 and i took some advice from a good friend who knows alot about atcs and the trx200 he told me to get a carb rebuid kit from a 84atc200x and the main jet was taller but it still would screw in all the way it was a no.108. and it didnt work.

Going from a 98 to a 108 is a lot of change. The length (height) of the jet is not important, just the size of the hole.

hey, a longer jet won't work in those carbs. it will bottom out in the float bowl, and won't flow. get the right jet from someone who knows.

hmm..108 is too big unless u got a big bore on that

[84trx200]

do yall think that a 100 or 102 would be good i still have a std bore wiseco high compression piston to put in.

yes 100 or 102 is perfect..im puttin in a .30 over 10.5:1 comp piston in there and im usin that 100 jet so id think ud be ok
