My Bad,

Confused needles and jets, but none the less, holeshot has more than one set while Ivan claims to have correct jets. I am seeking simplicity.

Holeshot:
3 sets of original Mikuni main jets
2 sets of original Mikuni pilot jets

Ivans:
This kit can be used with either a stock or modified airbox, modification instructions are included with the kit along with the "appropriate jets", (appears to be 1 set).

Simplicity is great!

But things don't always work that way. That's why Dale includes more than one set of jets. His baseline instructions will tell you which set to use, and for most people, that'll work out just fine. If by chance it isn't, you already have alternate jets to try. I'm not knocking Ivan, his kit is great, too - and if you want to keep the airbox, IMHO, it's a better kit than Holeshot's Stage I.

So with Ivans I keep the stock airbox? No modifications?
If I go this route I'd probably just add the K&N air filter.

No with Ivans you keep the stock airbox but modify it to the instructions i.e. drill several small holes in it, the instructions it comes with are more detailed and keep the stock filter do not go with K/N

Why not?

Same is true with the Holeshot kit. They say Dyno results are actually better with the stock air filter

If your wanting to get rid of some stock emissions equipment, Holeshot makes a pair valve eliminator kit thats pretty easy to install. Dont believe there is any performance gains, might lose a pound of weight

The mid pipe baffle is a piece of perforated metal laying flat against the inside of the pipe. I am sure it causes turbulance, but it is not a restrictor per say (you can see straight through the pipe). That muffler however is a big cork in the system. It will be tough to increase power to any degree with it on.

So all in all a good performance muffler and either "stage 1" jet kit will produce good results. I am getting ready to do all the maintenance for the summer and am seriously considering upgrading the muffler/jet kit, my only drawbacks are just how happy I am with the stock power.

Do the mods!!! I loved the stock power too but once i put the Holeshot high mount pipe and stage 1 kit on i had a new bike. More low end power, yea, but _all_ the power was so much smoother. and the throttle response is night and day better. Not to mention i GAINED 7mpg

do it

What size main jets, pilot jets, # shims, are you using?

I just went to #110 mains, up from 107.5, 117.5 pilot jets and 4 shims. Seems good in midrange and on top but rich on bottom. (we are both at sea level so I thought I might be able to make a valid comparison) ps I am now using a Holeshot 21" slip-on.

Banditofdoom · « **Reply #26 on:** May 01, 2007, 12:08:40 PM »

Is that question for me? If so, I am using the recommended setting in the instructions that came with the kit (cant remember them exactly, been awhile) and it worked fine. Same as you, a hair rich on the bottom but great where the rpms are most of the time. I use the comp2 14" can myself. Surprisingly hard to hear at cruise on teh highway

Banditofdoom,

I appreciate the reply. The H/S baseline settings are 110 mains and 5 shims but stock pilots. I put in the larger pilots because the 115s seemed lean on the bottom even with 3.75 turns out on the mixture screws. I might keep the larger pilots and just turn the mixture screws back from the current 3 turns out to 2.75 turns out and see what happens. Thanks again.
