Drz 400 s best performance mods

[Collinrandle]

Just wondering what everyone's opinion is on the best performance mods. I am thinking about doing the 3x3, the jet kit and maybe tailpipe or full exhaust. Is it worth it to spend the money for exhaust. Do you feel a big change other than sound. Trying to keep it cheap but what would be the best bang for the buck

what bike sm s or e

where and how do you ride ?

 

for me rejet w JD and 3x3 mod, tires (st legal knobs) and suspension set up for me handlebars and stock exhaust allows me to ride some street and mostly offroad with great reliability and low maintenance.  its not gonna beat a real dirt bike or street bike but does everything i want and quietly too.

Personally I did the 3x3, Cvk40, and stock pipe end cap. Next I'll do a full exahust, no reason really to waste money on a slip on. Be careful though, because as soon as you begin to mod it becomes an addiction!

[pumptrack]

Yeah! Do the 3x3 and jet it. If you're riding off-road and above 160 lbs., Re-spring it for your lbs.

Are you tall? Maybe some risers and a different bar is in order.

If you're not comfy with the riding position and/or have little control, extra power is almost meaningless. For me, anyway.

Bigger pegs too!

Everyone is different. I always try to mix performance upgrades with comfort ones.

 

For me:

 

1) full pipe

     A) jetting

     3x3

2) fat bars

3) lower seat (I'm old and short)

4) hand guards (see above)

5) DOT knobs

 

You can forgo the seat, bars and tires depending on your body and your riding preferences. I highly recommend a full pipe, 3x3 and jetting. (a slip on will help save some weight, but the header is very restrictive, so it is worth getting the full system. If you can't swing that, you can open up the end cap on the OE muffler) Hand guards are up there, too. Saves money on levers and doctors bills if riding off road a lot.

I mostly ride street. I'm not tall but I weigh 200. Should I set up the suspension differently. I ordered renthal jimmy button bend bars I hope that should improve my ride a bit. I think I will do the 3x3 mod and jet kit and won't mess with exhaust yet.

Best performance mods:

1. FCR carb (from stock Mikuni on my SM)

2. Seat Concepts Seat

3. Good Tires

4. Steel braided front brake line

 

I bought a Yoshi RS-2 exhaust system, sounds good uncorked but I'm not sure if the performance gain is there.

Handle bar risers tend to mess with the ergonomics of the bike (sit further back, different foot position).

Changing the gear is a waste unless you want to give up top speed (either way you change the gear ratio, top speed always suffers).

MRD-ZPRO shorty full exhaust system,  Hot Cams, FCR MX-39,  Seat Concepts,  Mobile 1 motorcycle oil,  Zeta hand guards with built in LED flashers,  Edge tail light,  1 1/8 taller bars,  and have fun.

If I do the 3x3 now and jet kit will I have to rejet again if I add exhaust later

Yeah, I would definitely do that or have that done. Spring for your weight for sure. It's going to sit up right in the stroke and handle much better. You have more control. Dirt bikes and dual-sports have such long suspension travel that it's IMO absolutely necessary to have springs that carry the rider's weight in the ballpark.

 

Then I'd also go for a suspension revalve, street riding or not. The DR-Z is heavy, and top-heavy, and it's not really damped enough - in other words the suspension's hydraulics don't "push back" enough - so the bike wallows and rocks back and forth a lot. It's easy to see when you see a stock DR-Z going over the same stuff as a better-suspended bike. It "boats". A revalve will again bring stability, agility, and predictability.

 

It's fun to ride them without, but it's a mod that I would always, always do.

Yes - but you just have to change the main jet, and the appropriate jets are included in the jetting kits.

In order

 

Re-spring and valve mods to the suspension for your weight riding conditions.

Proper tires for where you are riding.

FCR

 

After that you can do full exhaust, BB kit, cams, and whatever your wallet will stand. 

[epicadventur]

Could be wrong, but when your getting more air in (3x3 mod), you have to get it out. You can do exhaust later, but to get full benefit out of the 3x3 mod, you should also do the exhaust imo.

Baseline suspension set up , cheap to do .

Is this something I can do and is there a forum/instructional vid that could tell me how to do it.

[Collinrandle]

Alright so I think I'm going to do the 3x3 mod, jd jet kit, valve mods and re-spring. I am strongly considering an mrd full exhaust but do I want to spend 480$ is it worth it? Should I just do it because I will already be re-jetting anyways

You can change the springs yourself but unless you are a suspension wizard I would leave the mods to the valve stacks to a pro.  Tires and carb are pretty easy to do, if you search there are a lot of threads dedicated to putting the FCR on and what the jetting should be.  I say carb before pipe but it really doesn't matter.  

 

I see your are new here, have you read the FAQ sub-forum, lots of good stuff in there. https://www.thumpertalk.com/forum/215-drz400-faq/
