Maybe. I don’t know. Gonna try the 37.5 pilot and see where that gets me. I will go from there. To quote a movie “never give up. Never surrender!”

Like Dave J said...if your bike runs good with stock everything AND PMS out 4.5 turns better spray some starting fluid around the intake manifold area and see if idle changes...inspect rubber intake manifold carefully...could be cracked through or not sealed properly or the nipple on top where the hose attaches could have crack in that hoseLET'S RIDE

Order new manifold. I always use OEM but recently had 3 Road Stars that all needed new manifolds in past couple months....so I tried a different one from eBay and they worked fine (like $55).
You can hand port if you want extra power (very slight increase and don't over do it or you will hurt performance)...
Make sure you also get new orings and you will want to get 1 or 2 large sheets of 400_500ngrit sandpaper to sand the mating surfaces smooth. Make tontonus a very smooth surface for the sandpaper...use WD-40 oil on paper and sand mating surfaces nice and flat (a greenish coating is on those surface sand till gone). Make sure to use some pressure and keep manifold surface very flat as you sand (figure 8's work best). Takes about 20 min. Then clean manifold with soap and water and dry. Then install new orings (I use a little grease on o rings.
When installing make sure you clean head surface with paper towel and brake cleaner good...
Install by putting 4 screws in finger tight and use 1/4 in torque wrench, 5mm hex head socket, short extension, swivel...
Final torque is 105 inch pounds...start at about 30 and go 60 then 90 and finally 105 and go in criss cross pattern.
Kind of a pain in the ass but won't have any problems then.
Also while manifold is off bike you can seal the top nipple (I use a rubber cap and gorilla glue...works well. Some braze over the little metal tube. Assuming you have removed AIS and aren't using stock air box you need to block off this nipple or you will have nasty leak (bike run terrible).

I would buy new manifold for $55 and not try and work with old manifold that may not be sealing well....all the work to get it apart, sand, reinstall....I'd spend $55 and out a new one in there that will last 15+ years. I messed with re sanding and sealing cracks on one bike and 2 months later had the same leak.LET'S RIDE

Not sure if there would be any harm in using a 167.5 main along with your 37.5 pilot.....Dave J or Duke may have info on this?? If you did this now (resetting) you wouldn't have to do it again IF you ever went to pipes/air cleaner...LET'S RIDE
