    If anybody needs a manual or automatic de-compression top end head, I have one of each with matching cams too. The manual/early head should have one of the rocker arms replaced, but they are good otherwise. I also have a DR250 CDI (has earlier spark timing vs. the 350), an Eiger 82mm jug, a used 89.5mm DR441 jug+piston with no e-start holes for me :(, and 2 of my kick-start add-on kits with short levers to match. PM me, or I'll E-Bay it this weekend. Anybody else do a 5/16 crankshaft pin check and have results for my log?

    Here's a 5 minute video where I get stuck and lost on a mountain, so I take a random trail hoping it gets me down. Alaska is really green this year with lots of rain! Yes, I know my rear brake is screechy and needs to be replaced - the pads are starting to touch and I'm having to hit the lever harder! It probably only has a few dozen hard stops left before I feel nervous riding on the road... I would have replaced it earlier, but screeching the brakes can be fun :p

    I saw a brown bear 10-20 minutes before this video! I couldn't go back the way I came as I'm not dumb enough to follow a brown bear into alders without a weapon. Brown bears sleep all day anyway, so I couldn't just wait for it to move on and get off of my return home trail. Sometimes I carry a .45, but I don't have a holster that works well so I usually just bring bear mace. I'm making a bear mace holster that bolts to the plastic shroud above the headlight :) I've had quite a few bear encounters... I'll post pics when I make the mace-holster for my DR!

    Anybody remember Calvin and Hobbes comics? :rofl

    It takes a lot to get me scared. But, I have been to Alaska and the Yellowstone back country(during bear hyperphagia. In medicine, polyphagia (sometimes known as hyperphagia) is a medical sign meaning excessive hunger and abnormally large intake of solids by mouth.. I can tell you I was efffing scared. When you have to tell your fishing guides to go ahead and shoot at the bear if you are being attacked because the bullet hitting you accidentally is a better alternative to a mauling, shit is serious. When I first started my carreer in tattooing 25 yrs ago, I tattooed a lot of Calvin and Hobbs images.

    Went cheap, all used parts I had laying around...

    My '96 street model DR350 came with a big Eibach spring on the rear, I used that spring on a dirt model DR350 shock, and put DR 650 springs with cartridge emulators in the forks. It works well, I can carry my grand daughter on the back and some other stuff in the bags and not bottom out on rough terrain. Fairly smooth and fairly plush ride.

    The other DR350, the 441, is a '93 dirt model using DRZ250 forks with the same DR 650 springs, and a reworked dirt model rear shock with a big ass spring of unknown origin. Very smooth, very plush on rocks and roots, mostly don't even feel them.

    For those that might remember my situation....I had the nut on the crank that holds the timing gear come loose. Timing gear broke & it jumped time. Now, I'm acquiring parts (thanks Friedom). Upon reassembly, should I use locktite on that crank but? If so, red or blue?

    20170530_202715_resized.jpg I was on my bike the other day and needed to get home fast. Typically I would ride the road as it is faster, about 30min. However there was road construction going on and at least 15 min of delay. Co-worker said he was delayed 1/2 hour. So I decided to take my dirt route home. Mind you the trails around here are very rocky and since this current DR sports mostly stock suspension (dampener rod front, dirt rear) I have been been taking it easy. The dirt route usually take 45mins. But I figure if I ride hard I should be able to do it faster, and faster than the paved route. Since there was no traffic to contend with, how hard I road was the only factor. On this ride I really discovered the short falls of the stock suspension. Front end was surprising harsh, and would buck when slammed against rocks. Difficult to track a line when pushed through the curves or the rock gardens. Really made me miss my RM front end. The back end was surprising soft. Maybe I could crank the comp damp to max. Aside from the suspension I also feared for the tires and getting a pinch flat. I run about 20 psi and did not flat but a couple of hits had me worried.

    OK enough of my rally racer day dreams; I am probably slower than 90% of the local riders around here. The reason why I post this is because of the rear tire rub on the battery box. I have noticed a slight rub before but after this episode the inside surface of the battery box was almost completely void of paint. This had not happened to me before. I am running the stock SE big battery and box. I have a non cush rear wheel, mostly centered in the swingarm with the chain tension snails equally adjusted on either side. Aftermarket rim on stock hub. Running a 110/100 maxxis non DOT tire; seems like the biggest (widest) 110/100 I have seen before. 2 things that I did not check what the chain line or the dish on the wheel. Has anyone had a similar experience. Is there something else I could check. I am going to see if I can pull the battery box out a little. Looks like it is slightly bent in, probably from the numerous dirt naps this bike must have accumulated over the years. Could there be excessive swing arm pivot bearing slop, or simply the ohh so troublesome flex of our 3 piece open channel swinger (should have installed that scotts swinger). Anyone else have a similar issue and/or solution.

    So I ended up doing the ride in 35 min. Washed the front end out twice on the flat gravel corners, but saved it. Tore a couple of knobs off the old front tire.

    When I was younger a friends dad gave me a tip on going fast. You never coast. One should always be accelerating or braking, but never a steady speed. This should be obvious but made a light go off in my head when I heard it in words. Go fast. Take risk.

    Coasting is the only thing I do well.

    Cogent Dynamics (Asheville, NC ) sells a drop in cartridge emulator for the DR650 which has 43mm forks also. It's an amazing transformation. Betcha that would work on those old 350 forks too.

    I was once told "dirt bikes handle best under acceleration. You're either accelerating or breaking"

    I think you meant "accelerating or braking", but occasionally I have been accelerating then breaking! Which is why I generally stick to coasting.

    I think Muck might be right. Your either accelerating or breaking something. And by the looks of the current condition of his bike he broke something.

    I considered those on DR350 #1, but felt that having a beefier more modern fork was ultimately going to be better. I have a set of the 98-99 type cartridge fork from a drz250 that I plan on putting on this DR. But I am slow to act.

    My DR385 (the one I sold to Fredz43) had the cartridge forks from a '97 dirt model. My current DR650 (and the former one) were retrofitted with Cogent DDCs and .52 straight rate springs. The 385 forks had more travel but imo damping/wheel control wasn't any better than the 650's. DDCs are impressive.

    It's a worthwhile transformation and pretty easy to do as they slide right into your existing triples.

    I now also have a 2014 DR650 and I installed Cogent DDC's and .48 springs, as I am lighter than thump! and agree that they are very impressive. Prior to that I put the DDC's and Cogent's springs in my 09 LKR 685 and they were an improvement. even over the Intiminators that were in it when I bought it. Since my 99 DR435 has cartridge forks, Cogent recommends that I send them in for a rebuild and revalve, which I will do this winter. Good folks with very good products and service.

    Since I was on the borderline between the .52 fork springs and the .48's Cogent sent me both rates and let me try them out and decide for myself and then return the ones I didn't want for a full credit.

    Hello DR boys!! So me be a buddy got some plans on setting up an ultimate DR350 for him. So he's been hopping bikes like crazy lately ever since he sold the DR350 he had a few years ago. He put over 10k miles on it. Seattle to Arizona trip... off-road .. commuting etc etc. his ultimate reason to sell is he wanted snappier power and dirtbike suspension. But since then he's owned KTM 400 and XR400 and rden DRZS AND WR CRF ETC.
    All of them don't quite float his boat. Once he's wanting to put down some miles they're all too "dirtbikey"
    So we talked about making an ultimate DR350 for him that he could stay happy with. He's a engine machinist , so pressing, boring, valves cams etc. will be easy on his lunch break. Haha. I know with a dual sport your always compromising. But we're trying to
    Bridge a gap. The DRZ doesn't have the 6 speed and honestly doesn't feel faster or lighter to him. So here we are

    So we're thinking...
    POWER
    big bore 440. Fresh valve job. Pipe. Grind welds on header. Pumper (pipe suggestions? )

    SUSPENSION
    Front end swap (suggestions for trail riding mainly ) DRZ OR RMZ or ??? Re spring or swap rear?

    Weight
    Better Front end. Wheels. Get rid of rear subframe and make small aluminum with newer plastics (update styling) . Console delete. (Small trailtech) Lighter pipe no passenger pegs....

    Comfort
    Seat concepts. Wider foot pegs. Fat bars with rise.


    EXTRAS
    OVERSIZE TANK (maybe save some weight plastic vs. metal ) full hand guard. Trail tech lighting and speedo


    Please let us know what suggestions you have or ways to upgrade l. We have tons of resources at hand with a full machine shop at our disposal. He hasn't bought the DR yet. But we're hoping to get a good deal on a SE and buy a dirt model to swap some parts off of..
