Mr Woods knows his shizzle, I have used 210 mains with an EV27 and the plug was still a bit white so I went a grade colder on the plugs.

 

I'm going to try mine without shims on the needle or just one shim. Was running two but when I stepped up to a 185 main my gas mileage dropped off a little.

 

I am sure my gas mileage will suffer but it rides sweet, lots of low-down grunt...which is how I like them...

 

Tranny..........

 

I run the CVP velocity needle, which I believe is very similar to the N65.
I had considered adding a washer to try and help eliminate the occasional lower rpm/throttle roll-on light pinging issue I have.
Does anyone see this as plausible, or am I off-base?

 

It should work.

 

You just had to go and post something like this. Now I have to tweak mine to see what happens. Running a EV27, 46 pilot, sportster needle, and a 165 main. Runs great and should probably leave it alone, but not my nature. Thanks

 

Well I wouldn't want you getting bored now would I?

 

Been fallowing this and have a tuning question. 97 flstc carbed. andrews ev27 cam, Yost Power tube cv-40 master kit. 45 slow jet,170main jet,Idle mixture screw 3 turns out. Drilled 1/8" vent hole in float. Yost Blue needle C-clip in third slot from top. Bike runs great and pulls hard. However at cruising speed its a little sluggish if the throttle is mashed. If I slowly increase the throttle it pulls fine. What should I be looking to fix the issue?
