trying to get an idea on costs for mods

I've decided to mod the DRZ rather than buying something new. Searching the archives, I've come up with this much:

439 big bore $400

5mm stroker kit $400

FCR-MX $550

Ron Hamp cams/spring kit/Ferrera valves etc $934

What I don't know:

Any other important parts I'm missing to freshen up the motor?

Labor to install ?

Running Total so far is around $2,300 - $2,400 without labor.

what are using the bike for?

what power do you want to make?

First of all, it sees mostly, (95%) street duty. I have it set up for motard and I use it to commute with to work, school and hit the twisties with it whenever I can.

I race 250's (see avatar) and my other bike is a Z1000. The DRZ is great but just doesn't have the oomph that I'm looking for, hence why I started looking at other bikes. With all the great things I've read from the project bike and others who've gone for the big power, it seems that I can have the best of all worlds by putting some cash into this great bike.

Thanks for the reply.


what will you be using for a pipe?

i dont think you will be happy with the hotcams on this set up.

Almost forgot to answer your second question: what power do you want to make?

Well, I want to be able to keep up with bigger bikes (not top speed but not get left behind in the short straights either), I want something that's going to wheelie in 3rd, 4th, maybe 5th without throwing my back I want to feel that rush that I get with my Z1000. How that translates into numbers I'm not sure. All I know is there are too many times I say to myself, damn, I wish I had more motor in this thing.

Hope that gives you an idea.

i dont think you will be happy with the hotcams on this set up.

I have a full Muzzy system on it now but that could change.

ok,skip the hotcams.

when you call RHC to get valves and springs,get his cams as well.

Sounds expensive... Someone's bank account is screaming for mercy!

well, I look at it like this: spend 7k on a new bike or spend half that and make the bike I already like badder than a new bike. Besides, I've been a very good boy for a couple of years. I'm due. :thumbsup:

Well, don't skip town on us, I want to hear all the details of how it goes. :thumbsup:

edit in first post to reflect new info.

First off, let me say Ron Hamp is a very cool guy. I know next to nothing about engines and it probably shows but he's really easy to talk with and answers all your questions. Thanks Ron.

any progress XRChuck?

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
