mis matched jets in carbs?

[jraymer]

Been lurking on here for quite a while reading.  Have a 99, 

has;

Trinity stage IV head, not sure on domes, did a comp test at it was 150 ish. 

Trinity porting, 

Reed spacers,

V-Force 3 reeds,

Keihin PWK 28's 

K&N 3x5 filters. 

Not sure if timing has been messed with 

 

Pulled the carbs apart and the needle clip is in the middle, pilots are *42 but when i checked the mains, one carb had a 140 and the other carb had a 125??? Seemed odd to me, I am trying to jet for 1200 feet or so, I live in Vegas.  I read about ten pages deep into the jetting sticky and couldn't find a similar set up. 

 

Also a shop told me that reed spacers should not be used with V-Force reeds.  Any validity to this?

Match the mains at 140 and do a plug chop

140 seems extremely low. I'd go 290 at least with 30 pilots

He had keihins not stock

Oh

Thanks for the replies.  I will start working on this piece in the morning.

You might also check to make sure someone didnt drill the 125 out to make it a 140. I have drilled jets many times when I was needing a bigger one. I always scratched off the numbers but just a thought for ya. If you look thru a 125 and a 140 you can see a size difference.

As for which drillbit you need to drill a jet if you ever need to.

There are 25.4 mms to the inch and a 140 is a 1.4mm hole

So 1 divided by 25.4 = 0.039370079"= 1mm

0.039370079" X 1.4 = 0.055118111" approximate drill bit size.
