Bashplate and other mods on SM

So, in all my wisdom i have decided to convert my 05 SM for offroad use. I heard alot of people saying that the suspension isnt valved for it, but after two days of hard riding, i can honestly say it performed quite well. I sold the motard rims, and and bought a second hand pair of wheels off some guys E model. Im still running 15/41T and it worked quite well. I will be changing the rear sprocket to a 46T within the next week.

Now heres my problem. I bought a aluminium bash plate from B&B over here in australia. The thing is. it was designed for an E model not the sm. Will it still fit? I figure it will because both bikes run the same engine so obviously the frame in that area will be the same. B&B have no idea if it will fit. They said try it, if it doesnt fit, send it back for a refund. Pain in the arse.

Also i cant seem to find a company that makes a rear disc protector for the SM, cant use an E model one because the bolt spacing would be different, and the SM runs a larger rotor. Any US companies sell these?

Within the next month or so i will start modding the engine. Im at a loss which mod i should do first. The carby (kit from thumpertalk) or hotcams?

Also at the moment i am running a staintune exaust( they are an australian company, anywayz, i dont know wether i should ditch it and get a yosh or what? I dont know how much of a difference there would be in the two. The yosh would be better of course, but im guessing it would only be marginal?

Also my bike shop said that yoshi make a 450 big bore kit. Any ideas on price and availibility?

thanks all

      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!
