Storm jets.

The bottom one is two jets. That is your main jet and needle jet still screwed together.

Thank you for the help told you I didn't know what I was doing but I'm learning thanks to this site and members.

at around 600 feet (i think) i run 40/115 in my storm ... was a little rich before the cat was out and opened the air box, not sure yet after that. i suspect until i get a better exit hole, it will still be a tad rich.

That's why we are here. Don't feel bad about not knowing either. Not many people even know how a carb works, let alone how to identify the individual parts. Knowing is half the battle, and we all had to learn at some point. I learned about carbs on a 1976 Buick 455 with a quardrajet carb at the age of 16. My dad helped me remove it, sat me down at a table, gave me some tools, a manual, and let me get to work. Trust me, I made mistakes lol.

I'm still having trouble finding the jets that I posted in post 15. I purchased to sets and they are not even close. I even bought an online carb rebuild kit listed for this carb and it was the wrong one. I'm about to just buy the mikuni but what are your thoughts. Any help for the right parts would be greatly appreciated.

@Barlow where did you buy the jets for your storm. Thanks

This is the reason I recommend just buying a Mikuni as soon as you decide jetting changes are going to be required. Do yourself another favor and only buy genuine Mikuni jets. The knock-off jets are not made accuratly enough. For non-racing bikes I set them up this way: I set the idle fuel screw at 1 1/2 turns out, and change pilot jets until I get as close to a perfect 1300-1400 rpm idle as possible. Then I put the needle D-ring in the middle slot on the needle. Now I change main jets to get good open throttle mixture. I use the roll-on roll-off methoed. Don't do the full throttle test until you've been riding it for 15-20 minutes, so that the engine is well warmed up. Then ride it hot and winding, but not all the way to the rev limiter. Roll off the throttle 1/8th of a turn with the twist grip. Immediatley roll it all the way back on. If the bike immediatly revs, the main jet is too lean. If it stumbles it is too rich. You must do this in high gear in order to really load the engine. When you get the main jet right then adjust your idle mixture screw for highest idle speed (screw should end somewhere between 1 1/4 open to 1 3/4 open) with the idle mixture screw. Reset idle speed at 1250-1400 rpm. Now ride the bike back and forth through the 1/4 throttle position to make sure you have a smooth transition. If it isn't, adjust the needle up (Richer) or down (leaner) no more than 1 notch, and you should be good to go...ARH

Thank you for your response. Wrapping your mind around the concept of the three stages of this style of carburation makes the whole problem easier to solve. One more suggestion if I may - never make more than one change at a time!...ARH

Thanks for the links, I don't have any problem with this carb so far so I'll rejet with the exhaust modifications and see how it goes.

[china007]

So I took apart the two jets and added a 120 jet and it had the 34. I started it and it ran fine but then eventually died out. I used the hex 120 which fit instead of a round 105. When people say go to the Mikuni they are not kidding but it sure is fun going back and forth taking things off etc.etc.

Let me know where you end up so I can have a starting place! Thanks.
