hopping front end

My new to me 05 drz hops the front end when riding on the street it has a pirrelli scorpion 90 90 21 front tire the trailing edge of the tire is worn down as compared to the leading edge.This is a directional tire so I assume I can't just flip it to run it the other way. Both front and rear tires appear to have been balanced as they have wheel weights on the spokes To get it down the road properly do I have to buy a new front?

I would check the balance. If that is OK, then yup new tires.

I would re-check the balance. Does it have a rim lock? You can't change the direction on the rotation. When you check the balance or have it checked, make sure the rim is not out of round causing the "hop". If that all checks out its new tire time.



you didn't buy it from a bunch of mexican homies did you?


what is the tire pressure ?

you didn't buy it from a bunch of mexican homies did you?



Once, I changed my front tire and had a horrible bounce on the road afterwords, it turns out I didn't have the bead properly seated. There is a line in the rubber that goes completely around the tire by the bead, mine was not seating properly and by looking at that line, it became obvious what the problem was. Sometimes it's a pain to get it to seat right. At slower speeds, it felt ok but as my speed increased, it became obvious something wasn't right.

My scorp bounces a bit too, but the rimlock is a few inches from the valve stem, and I did not balance it. I bet you get that thing on a balancing rig and it will smooth out.

The pressure is low 15 psi. so I will air it up to 35 and see if it makes any difference. If not its off to the steelership:thumbsdn:

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      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!
