Probably the rite call. You did all the hard stuff. I ran out of $$$ so I couldnt do the Axtel bypass. I figure if I see my oil foaming I can go back in and change it out. It is not foaming at hot idle and reved up. I know pressure doesnt matter much but she has been consistently 15psi hot idle and 40-45 going down the road. 50 psi cold idle.

alan you should have removed oil pressure sensor and installed mechanical gauge into housing. and as you were turning it over you would know right away if you had oil pressure. that's what I use than you know

That was discussed quite a bit, even had a couple of free use offers, but Steve said and I agree that that pressure sensor is very simple and not prone to issues - never had a problem before the build. Steve has that gauge and will probably start there, if it is the sensor then simple fix and not much $ at all and my bike will be where I want it for tuning. Heck, I hope it is the sensor for sure.

Ive seen the discussions over there. Looks like a good fix for top end lubrication. Right now working on my bike is the last thing I want to do for a while. Maybe next winter. I did do the Zippers tensioners though. You can still shoot (pm) me his thoughts on it though.

Talked to Steve from GMR on Wednesday and yesterday(Friday). On Wed he simply pulled out the Axtell Bypass valve and polished it up a bit and reinstalled then on the second crank the Oil Pressure light went out. There was a long discussion on whether I should leave it in or not because it was not obvious what caused it to not seat properly. It was pretty much a flip of the coin feelings on both our parts and the decision I made was to just leave it in and if there was any more issues I would put my old stock bypass back in - not too hard, don't have to remove camplate just the cover.
On Friday, Steve let me know he was all done and my bike was ready to go. I was just about to leave for a 4 day trip so I will not be able to pick it up until Tuesday. If I recall correctly he said the bike produced ~ 102 hp and 112 tq. I was a little disappointed because even Steve thought I would get about 120 tq and I thought my hp would be closer to 110. We talked about my Bassani pipes and he had no experience tuning them but said for producing power they were too short and open. I knew this too and even Kurt from Bassani had told me if I was to do engine work to chose another model - at the time I thought I would be happy with just Stage 1
Steve also said there was a torque dip in the graph until reaching about 3000 rpms - I have seen a chart of the V&H Competition Pipes and it had a major dip, I think the 1D5250s are a milder version of those.
I will post the dyno sheet when I get it, and let y'all know how the bike feels. Just plan on riding for awhile, may do a rear pulley swap and I will be thinking about replacing my pipes but will most likely keep my eyes open for some used D&D Fat Cats.

Allan don't mean to sound like a A$$to you but the rear pulley and the exhaust is not going to get you at 120 square . save your money on the exhaust your concerned area is the heads. with a 1.900 intake and 1.575 exhaust your engine will not get the cylinder fill to produce those kind of numbers that u were looking for period. and as for as the exhaust J Pace has a hillside 107 with there stage 4 heads. cams are very similar and throttle body the same and he is running the same bassani exhaust with 130hp/129 tq so that exhaust is very capable of producing good numbers.

I have followed this whole thread. Glad to hear you had a positive outcome. I am a long term "shade tree" mechanic and so appreciate all the work you put in to taking pictures and posting your progress. This type of detailed, first hand experience is very helpful to DIY'ers like me. Again, many thanks for your efforts and ride the hell out of that puppy!

your not going to gain 20 hp with and exhaust change.
