Breaking new bike in on Dyno - good or bad??

    Looking at buying a new RK and getting SE Heavy Breather, SEPST, pipes and CAMS installed on the bike before taking delivery as part of a "package deal".... (if I can get a good price that is...)

    Only problem is that it will obviously need a "tune" on the dyno because of all the mods.... can a brand new bike be safely broken in on the Dyno???

    The other option I have is to get all the work done at or after the first service, but then I would be paying full price for all the stuff.

    Thanks for any advice.

     Berms, see if ya can't crack a deal with the dealer to include the afters in with the total purchase price and for them to install at the first service.

    Most would be happy to do this.  In fact I think most would rather do that than let the bike go out the front door in contravention of their dealership and licesing responsibilities.

    Personally i'd prefer to run a bike in myself rather than risk anything going on that I didn't know about on a dyno.

    A proper break in on a Dyno would need a very experienced operater, and quite a few hours of Dyno run time.
    If your looking at a basic Cam/pipes/breather setup, you should be able to pick a SEPST map that is safe enough to get a few hundred km's under your belt.

    TTS mastertune is the way go mate if your planing going aftermarket cams, exhaust and head-work down the road. I've been fitting major hop up parts to my bike for 3 years and never had it dyno tuned yet. Don't waste 300 or 500 bucks every time you add a new HP part.

    alot of the bikes i play with an build motors or just touch em up a tad i try get most ppl to fit an AFM on em cant be real time diagnostics while rideing besides i had one mate that seen his gauge say was lean so pulled over an saved himself heap bucks he fucked around with inlet manifold an forgot to do up a bolt gauge showed outta stioch an he got the trailer to pik him up found prob an fixed off he went on his merry way
    when i did issues2 engine we fitted a air / fuel gauge an when he took it to the dyno just outta curiosity the tuner said he didnt have to change a thing so that speaks for itself as far as im concerned

    I've been checking out the RB air/fuel gauge. I might invest when a save enough pennies to complement the TTS.

    I understand mate it does take a effort to tune with the TTS unit. But with all honesty I normaly only run two or three Vtunes and call it done. Never had a problem no matter what parts I fit to the bike. Some people go way over board and spend way to much time Vtuning. Have you worked out what cams your going to run in the new bike.

    Berms if I brought a new road glide and was considering a stage 1 kit with cams I would buy the Kuryakyn perfect storm kit with a set wild things torque cams and use one of his TTS base maps to Vtune . Steve from GMR has had great results using these kits with no torque dip and pushing large numbers. Do some home work on these power kits and you wont be disappointed.

    Thought i'd ask here rather than starting a new thread. I'm familiar with the Mototune technique and have used it when running in new sports bikes with their high reving engines, but being unfamiliar with Aircooled twins -
    In taking delivery of, and stretching the new legs on my bike, is it better to vary the load like I did with sports bikes? (keeping off the freeway and stretching out the motor on take off, to a point - rinsing and repeating to vary the load and revs) or is freeway riding with slight speed variation and a lot of air over the donk ok?

    Taking delivery from Blacktown Harley....riding back to Belfield... then considerin the brake in plan from there.

    Try and avoid traffic ( big ask from Blacktown !) Vary the speed yes, and never "lug" the engine at low revs.
    The last 95 build I did, after a few heat cycles, I used a similar but less severe method to load the rings and run in.
    Basically just ride it normally, but avoid high revs for a few hundred Km's. IMHO
