Quick question, would I need to replace the push rods when replacing the cam with an Andrews 57H ?

 

Push rods and lifters for sure, at a minimum.

 

Did these rineharts need any tuning after install? Some say they needed and other say does not.😍

Thanks

 

intake and pipes should at least be tuned with standard map from pv or a 3 button

 

when I was stage 1 no I didn’t need a tune . But after stage 4 of course I did. My bike is tuned with Direct Link from a real good race tuner . He said lot of guys don’t like direct link cuz it’s the racers tuning system . All I know is the bike is blistering fast . I smoke my bike wife’s 2020 R6 from 0-80 mph bad leaving her . Of course After that it’s my *** , but for a V twin that weighs almost 700 lbs and 3 times the displacement I’ll take it .

 

id have to see that..but...anything late model can benefit from at least a tuner just since emissions is a lean setup to begin with...

 

very true . I had it on the dyno when stage 1 just to check to make sure fuel and air was good and I could have us a tune cuz it spent heart but I didn’t want to spend the money cuz I knew the future of my big bore build shortly after. As long as it ran safely with a stage 1 was all I was concerned.

 

the whipping on an r6 part...lol..i roadraced and r6 for 5 yrs....no breakout ever run with that

 

It’s stock. I have a sick amount of bottom mid torque . I couldn’t believe it either . My builder said it’s the quickest bike he has road and told me when I said I wanted to do more why , just get a Busa . It launches like a dragster . Now if I’m cruising at 65 mph and we drop she leaves me like a federation star ship . But from a dead stop at the light I get two bike lengths on her and she passes me heading past 70 to 80. You’d have to be there for believe it and If you raced you stay at a constant higher speed and above . In that scenario she crushes me so your view point is different then mine . I’m taking drag racing and for a distance due to my torque I eat up people early.

 

also there is no lag on my bike . With that much torque off the clutch and the bike being hard to ride at parking lot speeds just to coast because it wants to buck you off. So if I’m just cruising at 20 mph or from a dead stop and
drop its instantaneous and I’m gone . No getting the R’s up getting into power band which is fast on a sport bike being over square and lighter flywheel we all know but that second of lag I leave the R6 and I shift and it starts all over again. My bike creates enough torque to pull the front wheels up with the breakouts long wheel base. My point is not that I’m faster then an R6 cuz I’m not . It’s about what makes a Harley fast , being torque like a diesel not horsepower when a Harleys HP peaks at 5252 on an under square engine when the race is over on a heavy cranking V twin . I built it around that principle and it’s why I smoke other harleys with better dyno numbers but bad torque curves . Down low at 2500 to 3500 harleys have no horsepower if you look on a chart it’s all torque carrying the bike lifting the front end up and blasting . I’m not saying horsepower dower matter . It does but in the meat riding range of a Harley the hp isn’t there and it’s a calculated number , that is why it always peaks at 5252 . Of course when I’m cruising at any speed above 45 if I’m next to my wife she leaves me like warp drive . My point is how fast a 700lb bike can launch . These people with big Horsepower cams that wake up with torque at 3500 plus can’t spool like a sport bike with lighter crank so your waiting to get into the torque if it’s not low to mid and your always gonna weight to get into the peak horsepower when it peaks at 5252. They way around it is have a cam that delivers torque down low to mid and it’s fine to back It up with Horsepower up top to make it complete . People scratch there head when they have a 550 Hp cam in a 131 and have 25 more horsepower then me and there torque may be the same as mine but it comes in at 3500. Anywhere from light to light . Back roads in controlled distances up to quarter mile I destroy them because of my torque curve . All that 25 Hp means nothing down low and mid when you don’t tap into it until 5252 . My example was just how billet fast setting up like this can be. When your racing a sport bike on a track doing 100 plus of damn course it’s gonna eat my breakout and lap it . When cruising 50 or so of course the R6 is just gonna leave me . But from stop to slow speed starts I just bolt on them for a snapshot before they get into it and 60 -70 mph comes quick like a reaction . Turbo diesel trucks with 1000 lbs of torque do the same to some modern sport cars of the line and at slow starts but it doesn’t mean the diesel is faster then the sports car . Sorry if you took it that way but that isn’t what I was saying and maybe I should have been clearer so it’s my fault .
