boysen quick shot not for 07

[450rJam]

the boysen quick shot I was looking at says it wont fit the 07 ?
is there a chance that the 07 has a better design and I wonder if it would be better to replace the 06 pump with the 07 instead of dropping 80 bucks on the boysen ?

the 07 carb AP circuit have been improved...

any idea what they changed on it

yes (picture from GPracer2500)

FCR leak jet, AP circuit valve, and diaphram

is that bowl from a crf or a trx. for 07 the crf has a 41mm but the trx is still a 40mm. I pulled up the parts numbers and the 06 and 07 trx are the same for every thing diaphram, pump cover, and leak jet but the entire carb as a hole the part munber is different so something has changed. So maybe the quick shot would work on the trx but not the crf. My brother wants one for his 07 trx thats why I question.

i machine carbs and they the 07 carb is different with the AP circuit and should not require the QS. If anything a richer leak jet could be used....
