Headwork??!?!?

[Nubz]

Just curious how expensive head work is on an inline 4?

Totally hypothetical situation I was thinking in my head nothing I was going to attempt to do.

There has been a lot of talk about increased performance on here...and I believe that changing the cam was the better option...in fact Marthy had done that... do a search for cam...

Look at my airbox mod thread... + FZ6 cams + exhaust + 4 degree timing advance mod.

The head could always come off and get shaved to increase CR a bit and clean up some port. But the gain would be very minimal, not the 70s anymore where ypu coild gain 50 HP from a good porting job.

If you get the "Marthy package" done right and well tuned you will be happy. I personally think that was about as good as it could get without dumping another $1000-2000 to it.

Marthy got it

If you want to go fast on the cheap, they are ugly and sometimes beat up, but there are early 1990s 600cc-1000cc supersports on craigslist for a grand or 2 in my area. For the price of a 5 horsepower port and valve job, you could own a 10 second bike.

You guys missed my point I wasn't thinking about doing it LOL.

Bench racing in my head after a few drinks is what influenced this post last night :zombie:!

Guy on fz6r facebook page is porting his bike. He already has fz6 cams. I'm happy with the full Marthy power package (exhaust, maps, fz6 cams, etc.). I'll probably get another bike before I go as far as porting. Weather is fine ally breaking here, braaap!

That's what I did... FZ09 is a nice little beast and a 600SS killer

I'm sure you remember back before the internet Marthy a guy would get an idea next thing ya know he's 5k in the hole and got not even close to what he was looking for LMAO.

I see the point guys and I probably wouldn't do it without a different bike I was just curious how much guys that do it get paid.
