I posted this in the Tourer section but, didn't get any response so, I'll try here in case someone has some general experience/advice from similar work done on their own twin cam.

I need to get the topend refreshed (valve seals & rings) due to my 2004 Road King (Carburetted model) burning oil; it's done 92,000km. Considering whilst it is apart, sticking a big bore kit into it & maybe cams aimed at good solid mid range torque.Does anyone have any experiences with big bore kits for a carbureted TC88, 2004 Road King or similar

Any recommendations, prices (ie: what is a reasonable cost), should I include Cams in the upgrade or are there better options to consider (other than buying a new bike, which I can't afford).

Thankyou in advance

I not sure what ci you can take the 88ci too, maybe 95ci? but definitely do everything at once like cams etc

If you can't be stuffed, get the stuff fixed/replaced, buy the pipe and cam

95ci or 98ci rebore on your stock barrels, heads get guides inspected seals change, valve seat done and decked to set compression in cam you pic

Cheers Gents,

I have a Freedom Performance Union 2 into 1 pipe coming (courtesy of Fatbat); any recommendations on a Cam? Looking for a bit more grunt across the whole rev range rather than top speed increase.

Hadn't thought about reboring stock barrels, assume that would be a relatively cheaper option than new barrels?

Here is a convo between my engine builder and me RE: specs and price on a 95" build for my '01 Heritage.

 

 bore and hone your pots and fit SE  pistons 10.25 comp (actually went with 9.6 in the end)

gaskets cometic

new high volume oil pump , standard cam plate fine , new cam chain tensioners

cams to suit compression ratio  + lifters+cam bearings (Crane 302 cams, similar spec to SE204 or S&S 583)

port work on heads and 5 angle seat and valve work , you model has very restrictive exhaust port so lot of time removeing metal for improvement

new cam bearings all round

performance ignition , to allow eng to run above 5200 rpm , most mild 95 builds peak hp around 5600 -5800 rpm depending on exhausts (Dyna-Tek DPI)

eng assembled ran in on dyno ,and  tuned , + oil and fillters changes dureing running in and redone when finnished tuneing

gear box and primary oils changed ,

total cost $ 4,000 , all the above items  rebuilt ,run in ,and tuned on dyno + full service to eng, primary,gearbox ,   the cv carby are good for 95 rwhp and run nice , for strong torque eng the cv is great carby.

I couldn't have been happier when I got the bike back. It made 91hp and 98tq with a V&H exhaust that is known for its good looks not its power making ability. (Big Radius 2+2)

Obviously if you or a mate can do alot of the work you could do it cheaper. I say if you have to do the heads anyway then get a nice street port job and go a 95" to 98" with mild cams. Remember the ignition as it is something that is often over looked.  Well worth it in the long run mate. 

Hope this helps with some ideas.
