2013 Softail Standard
Dave already got me to upgrade the 103 with a set of reaper 574 cams, shaved heads and a 1.9 intake valve this was quiet impressive with 98HP and 108 Torque

Now that he has been bitten by the HP bug we have stripped it down again and had the changed it up to the below specs

CP domed 107 Pistons 10.8/1
Tman 590 cam
HPI 55mm TB with 4.9 Injector
Heads have been worked over bu a local head porter with
2" intake chamber worked on
both intake and exhaust ports shaped

haven't seen the flow sheet but 300 @ 600 is what I have been told.

Will start putting this back together this weekend and it will go up to Thundertech for a tune pretty quickly after a 1000ks are put on it

some pic's of the heads ( not the best but gives you a look))

hi ando , was there new correct size seats fitted to suit 2'' values  or just 2'' valves fitted in old seats ??? just wondering

new seats fitted,
this is the first Time I have used this guy he is a really good bloke that seems to know what he is talking about and has all the gear, has a good rep but likes to keep to himself, if this build turns out as we expect I will be getting him onto my MVA heads.
The bike owner has taken a gamble letting me get his heads done.

2 '' value will work well in 107 '' nice ando , if he has around 300 cfm at .600 lift ,thats very good flow , get him to flow them with manifold and tb or carby and backing plate and see what figures you end up with , then you can cross reference cfm with rwhp it makes for rough idea for future builds , best flowing heads no good if what is infront is restriction ,all good work goes to waste , hope build works out nice , the intake should good , i have been running hpi t/b and manifolds for last 8 years , nice gear cheers

this guy has a few different ideas from what I have seen and heard he has even shaped the combustion chamber a but as well which is not to common a practice, but if it works it will be good and the onwer of the bike will be happy

un shrouding the valve , cool ,

Hilly not entirely sure but 2" is getting up there, we fitted the 2" valve and some FT CP pistons to check valve piston clearance and they where well inside the valve relieves in those pistons but they would smash into the stock piston relieves (post some pic later)). Valve angles on the MVA I don't know yet but will find out soon.
The plan initially was to run FT pistons but when he shrouded the valves we had to go the Domed pistons to get the required comp.
We will mock it all up again and check all the clearances to make sure it all fits

checking Piston valve clearance of the 2" intake valves

Hi. just writing something so I can watch thread.

will keep an eye on that cheers Rob

we are using Manley Valves not sure if there is any or much difference between them and the AV&V valves

just spoke to my head man and it is a 1.625 exhaust valve.
Valve to valve clearance has been checked and is all good

evo heads suffer from shrouding one one side of inlet and exhaust  , they can be easly modded with correct items ,  then some time with over size valves you can also get bore shrouding , restricting flow , inlet valve size is normaly determind  by bore diametre , so big some times is not always better , in the case of the 3.927 bore in this case 2 ''  will be fine

Hi,

When i doing the big builds i use a bit of blu tack

Thanks
Robots

got this 107 back together and started like it had never been apart, have got two heat cycles into it and will get a third one done then take it for a run. It sound a lot angrier than it did before and just sounds like it gonna go good.

here is a couple of assembly pic's of checking clearances

Fired the Softy up today
This is it after 3 heat cycles and taking it out on its first 5ok ride before Dave get back from work and put another 250ks on the build

and why the fuck does my Pics and vids turn out shit on this forum and no others

the final results this is a pleasing result if ya keen on numbers ad 10% for a true comparison

Look at the sheet I reckon the way it makes power all the way to the rev limiter the heads are doing there business and its other factors that are stopping it from making any more HP

Also has a broad torque curve and its set up at about 10.6/1 comp

Awesome numbers for a 107. Why the dip down low ? Starts good drops off sharp then comes on strong.

very nice figures ando , quality job

I think I am on a winner with this head porter I have at my finger tips

now to get the same HP/CI ratio outa my 120
