Spike Filter and Tuning

[jeffwest5599]

Installed a spike filter on my 08 k-9. Idles fine just cuts out when I give full throttle in lower gears. Wondering if that is a jetting or accelerator pump adjustment.

Did you remove the auxiliary vent plug?

Start with the basic adjustments and then if you can't get it dialed in look into changing the jets which is a little more involved. If your only issue is what you described the accelerator pump adj is a likely suspect. In this guide step # 11 refers to what mleach72 is asking.

My experience with the Spike before I sold it and went with a dual runner was frustrating. Never could get it dialed in perfect, I put in a #60 on the air bleed jet and had to point the spike straight up to get it to stop cutting out on accel, spent a lot of time trying to tune it and was never happy so I went with the dual runner and never had a problem. I know some don't have problems with them, just my experience.

Yup! Must Do.

If the S&S teardrop air cleaner is being replaced with an aftermarket air cleaner, be sure to remove the auxiliary bowl vent screw (#14). (as stated in the tuning guide posted by [B]Mikeinjersey[/B])

Yup! Must Do.

All. I removed the aux vent bowl plug as listed on the s&s site and it runs like a champ. I assume it was just running short of fuel. Appreciate everyone’s response.

Awesome, glad you got that Dog running the way it should

IMO, a good filter should not need any adjustment.

filter should not impede flow.

I have a fuel injected bike was wondering if anybody has used the trask high flow air filter. It's the one that you can see through it and it's round.

A couple guys have installed those type of ac's. I think @Mastiff Rider64 was one. They are meant for harley carbs and efi, so you need an adapter plate. One guy drilled the backing plate to make it work. I forget who that was.

Yep I have one and it's great once you replace the paper filter with a K&N filter.
