Upgraded Camshafts

hi guys im looking for some advice, KentCams just quoted me £239.00 per pair + vat to have my current cams reground or £805.00 per pair + vat for new billet cams.

To me having my current cams reground seems the obvious choice, but can anyone see a problem with this?

Has anyone got any previous experience?

 

Cams depends of what you re looking for power / torque / rev range .

best solution is to put in piston , not cams for a street engine.

 

it will be the same profile either way, that's what KentCams said, engine will be Getting +2 CP pistons with the rebuild too

 

Yeah , good choice for the pistons , a lot of torque everywhere, where will you do your cylinder honing and plating ?

Don't buy the billet one, no advantage for us, just regrind your OEM.

Do you plan to change rods ? What compression ration do you want to achieve ? With +2 and high compression , Carillo rods are welcome.

 

I the we have already spoken about this briefly in another post foenix, I plan to use Carillo rods. Langcourt seem the best place to get the cylinders bored out and plated, unless you have a better recommendation? I plan on removing the balance shaft and having the crank balanced and knife edged, along with decent head work.

 

Millenium in USA are the best plating place for our cylinder.

With balance shaft removed, you ll have to adjust perfectly the balance ( if not you ll have vibration ), and your bike will be agressive on the throttle.

With our modern engin, we can conserve a heavy ( if i can said that lol ) crank, to have a smooth power curve and smooth throttle response, to have a better ride.

For example, the s1000RR have a more heavy crank since 2012, and the blade the same since 2010.

Piston + cam +headwork is the way to do !

I have send my head to KWS in the USA, but i f i have to do another one and more $$, i ll send it to Tim Radley in the UK ..... but expensive as hell

 

id rather go with uk companies for ease of shipping, I friend of mine races and he put me in touch with good places to get work done aggressive throttle sounds good to me

 

Be warned I think youll need valve springs if you get cams so it gets very dear very quick for all of about 10hp

 

yeah valve springs are already on the very long list of things I need

 

Tim Radley makes the best head in the world, worth every penny.

You ll need valve springs if you get cams with big lift ( i don't think it will be your case on the road ) or if you ll put HRC ecu to past 14 000 rpm.

If you re stay with common lift and stay at 13 200 rpm, you dont need valve springs, keep this money to ceramic bearing for transmission .....

 

There's a joke in there somewhere!

 

??????

 

Its english word play foenix, head = blowjob lol

 

lilllllllllll really ?? lol

I know only " blowjob " for that, thanks now i know another good English word !

 

Have you got a power reading before the work?

Be nice to see the differences on the same Dyno.

 

unfortunately not as the work im doing is to a second engine I purchased just to have a play with and do the work to, I knew it was going to take me a long time to do due to funds so I can still use my bike while im building

 

I know cost always plays a part in decisions, but it's always better to run billet/original size base circle camshafts than reprofiled ones as if made spot on, eg same size base circle. Tapper adjustment will be ok.

Also the cam followers/buckets have to come out the head more to meet the smaller reprofiled camshaft.

Another thing is the cam will turn more freely with a larger billet cam lobe.

 

is all that really worth the extra £600 tho?

 

cams and springs 1500?
gaskets 100?
gas flowed head 700
labour 200-400?

10hp

I'd rather just ride it with new slicks every time.
unless you can ride it like o'halloran then it'll not be the only thing to make you faster.

you might end up needing pistons and rods once all that's done.
maybe a bigger rad?

let's not forget an uprated gearbox
