    Adam you’re posting this repetitively here and in multiple yankee forums. From what I’ve seen you’ve been given heaps of advice and lots of good advice. Dunno if you’ll get much more here. Getting into it might be the go

    Yeah, I've had lots of advice.  Some opinions contradicting each other. Just makes it more confusing. 
    Just going to get started by pulling my motor down and starting with pinion shaft runout.

    Making the right cam choice is no different to picking a room colour or bathroom tiles, the closer you get to doing the job is aided by narrowing down the choice, not broadening it with more colour cards or shades of tile.

    Cam choice is dictated by a few defined variables, capacity [you already know], compression, head capability [not just flow but what can be physically installed] and requirement. Some people also have a manufacturer preference.

    I have seen some incredibly poorly chosen cams, usually based on opinion or a completely unrealistic expectation. As in the first paragraph, there are some hideous decor choices around.

    Fat Bat. 
    No offense mate, but your reply added no useful information, and I'm not "posting here repetitively". Are you keeping count? Did you not have nothing better to do at the time?

    Anyways, I'm at the critical edge of compression and camshaft choice at 200ccp with one of the build options I have and decided to see what others had done in their 95" / 98" builds here in Australia. 
    Yes, plenty of info on US sites, but does not always relate or translate exactly. Different fuel, different headwork, different dyno tuners etc etc.

    Has anyone run the CR575 in a 95" - 98" build?  Intake close of 35* would allow me to use a lower compression piston and keep ccp at around 195.

    Adam, inner cam bearings on 99-06 (99-05 on Dyna's) twin cams are .875". Inner cam bearings on '07 & up ('06 & up Dynas) twin cams are 1". 

    Conversion cams have the .875 inner journal, and 1.00" outer; for using the newer style cam plate in older motors. Hope this helps more than my last post. Sorry mate, didn’t mean to sound negative. I just thought you had so much info you would be right into it. I tend to procrastinate and over think these types of things and need a push to get into it. Sorry mate

    No worries FatBat, all good mate 👍.
    I'm sticking with  the oem '02 Cam plate and pump at this stage. Don't really see the need to upgrade except maybe the Baisley spring and oil pressure valve mod. Depends on the state of the chains as well, if I have to replace worn chains then might consider a cam plate upgrade. 
    Cheers

    And yes, sometimes too much information and too many opinions just makes things as clear as mud.  😂

    Would be keen to see what you end up with and what you're aiming for.

    I've got an 88 on the bench I'm about to get stuck into shortly. Have SE pistons and SE259 cams that where picked up for dirt cheap on the shelf that'll likely be used.

    Nice. Always good to have parts on the shelf and to use what you have. 

    Are those the SE cast or forged pistons?

    Theyre the high compression cast set for 95in, however one of the pistons has a slight nick in on the skirt, so I need to chat to the bloke that does my cylinders to determine if they're even usable. 

    Im leaning towards running them anyway.

    Need to pick a cam plate soon too.

    John, sounds like a good plan. 

    Love the FXR in your galley, very nice build!

    speak to wes at cyclerama or the lads at alpha performance in qld who use cyclerama cams a lot if your interested in using the 575 cr cam.that cam can be used with stock compression but likes compression to 10.2 also.

    Any decisions yet Adam?
    Cam choices are currently doing my head in! 
    The original/current plan is:
    10.25 pistons
    Se 257 cams
    96cu Heads. 

    Now im worried it's going to too far in the top end and not pack enough mid too.

    What are you aiming for from the motor?

    The SE257 will require some decent heads and around 10.8:1 to make it worthwhile.
    It will still be mid-top end power in a 95"
    I'm running the Andrews copy - TW67 ,  in a 120" .
    Totally different build in every way, but it has a decent amount of low end torque due to the extra capacity, and doesn't stop pulling .

    Heads will just be the later model ones whichare an improvement over the 88s, decked to bump up CR a bit.

    The whole thing does my head in, i wish I could just drop the whole lot off to a guru but there's  noone local.

    If your set on stock heads I would avoid the SE257.
    Also if you are set on using the 10.25 pistons it limits Cam choices.
    There are a heap of different combinations I could throw at you that would work !
    An old favorite is Andrews TW54, - would bolt in with later heads - 10.25 pistons and no decking needed, comp'  set at 10.2 .

    Think I've landed on a setup and will be getting rid of the SE257. I like the idea of high HP, high RPM but realistically the bike will be used for wheelies and mucking around so probably needs a bit more torque in mid.

    The SE plate is looking like real good value too.

    Not yet, I did pick up a set of brand new Cycle Rama CR575 chain drive cams that would go nicely with the Wiseco tracker 95" pistons and set me up at exactly 10-1. That's as far as I'm going until I pull the top end and see what's in the cam chest.

    I would also look at the Andrews tw54 or s&S 570. With 10.25 compression you should be in the sweet spot for both those cams which produce good power. 


    I may end up selling the CR575 cams on if you are interested. They are a good HP and TQ cam, but could do with a set of better flowing heads. I have a set of 96" heads with less than 10km on them  (taken off a bike before it even left the dealership 11 years ago. 
    If you do go with the SE cam plate I'm pretty sure you're limited too conversion cams only?

    Thanks crowster, only just read your post and I did actually speak to Wes at cycle Rama and ended up with a new set of cr575s. 

    Not sure if I'll end up using them, but if I do I'm sure they'll go really well. 👍
    Cheers
