I'm running the stage 2 needles with the clip on the 4th. 180/185 mains. I'm at sea level.
Craycraft 686

 

was running 148/150 with needles on the third position but couldnt dial it in right as it warmed up so switched to 155/160 mikunis, much better.

 

im running stage 2 needles on the 3rd clip down with 190:185 at 600 ft above sea lvl

doubled valve springs
bored .5 over - wiesco 11:1 piston
big gun exhaust - header - muffler

 

Xx is that dyno jets????

Who has the chart that compares dyno jet sizes to the regular mikuni sizes?

 

I am running 175-177.5 mikuni mains along with DJ needles at a custom location around sea level. Mikuni mains are roughly 10 sizes larger than DJ mains. My setup is 10.75/1 JE, Stage 1 HC, P-bomb header and an e-series /w 12 dics and no endcap....this puppy is loud.

 

Thanks Gary, for some reson I was thinking it was a progressive gain.
example: 148DJ=150mik, 150DJ=155mik

 

I noticed the stock Raptor comes with a 140 / 145 jet combo (5 numbers in between).

I installed a White Brothers R4 Silencer (only) and increased my jets to 145 / 150.

I see a lot of folks only have 2 or 2.5 between their main jets. As an example, I noticed kyraptor23 has a combo of 148 / 150.

Why do some folks have 5 numbers between and others have 2 or 3 numbers in between?

Does my 140 / 145 combo sound right for a new Raptor with a WB Silencer, stock airbox and no other mods? I ride at sea level.

Thanks!

 

how can you use dyno needles and mikuni mains wouldnt that equal out to like
200 dj???

 

You can't, TRUST ME!!! If you are you will NEVER get it tuned in right. I struggled with that for a long time and didn't realise thats what my problem was. Swapped needles and had WAY better luck then.

 

does anyone run 180/185 dyno mains ?
