You bought a new coil before you had swapped the plug? Seems arse-about-face to me.

Good luck with the ongoing improvements. I'm sure you'll have it running sweetly soon enough.

Can anyone ID this carb? No model number or serial. The build up just mentions it was a dirt carb instead of the stock carb that came on the 91 dr250.

[slowsuki1]

mikuni tm31 or 33mm, is what it looks like,if it came off a 250, it is 31mm, 350 33mm.

Looks like a tm33

Yeah... That's how I do things.

Just a bit of info on some bar risers that worked out for me because I had the stuff laying around.I have two LT80 quads that I bought for parts to fix up another.I was able to use two of the bar mounts and the long bolts from the quads handlebars to raise my DR bars up 3/4 of an inch which is not a lot but in my case,any rise was a huge improvement.

Hey guys. Noob here planning a father&son TAT ride and considering a 93 dr250 (s? se? it's the dual sport version) and 99 dr350sex (dual sport version) as the bikes to do it on. I have read at least half this thread but haven't been able to answer my questions. I have no idea what the letter codes for the 250 should be, I think it would be an S or SE and I think the 350 is an SE, never seen the X (maybe it's a joke? SEX) but again, I'm a noob. My question is: what consumables interchange? as in brake pads, oil and air filters, clutch and throttle cables, brake and clutch levers, seats, fuel tanks and petcocks, carb kits, etc. Both bikes need at best some TLC and at worst rebuilds of everything but the engines/transmissions. I plan to grease suspension and wheel bearings, replace appropriate seals, lube or replace cables (and carry spares), replace and carry spare levers, change any vacuum petcocks I find (don't own the bikes yet, planning 2 retrieval trips this weekend), and probably make at least 1 gas tank swap, might buy a Corbin seat from the flea market and want to know if it'll fit both bikes or just one. Thanks a TON for your help! hope i join the DR ranks soon!

The X in sex is year code. I don't have any experience with the 250,but it's my understanding that it's the same bike just a different motor basically.

Howdy, I am looking for a kickstart lever for my '90 dr350s. More specifically a shortened one. Last summer at a KTM demo ride, as a KTM employee was trying to tell me not to give my DR any gas while I was starting it (like it was sum newfangled fuel injected bike), he made a point that newer bikes have shorter kickstart levers for less torque, faster rotation. Makes sense. My DR isn't too hard to turn over, unless it's in that one spot in the rotation, so I want to look into some possibilities. Anyway, any help would be appreciated, like if newer RMZ levers will fit, or even just the size of the splines. Thanks!

Also +1 on the needle seat being worn, however if it was leaking you'd be getting gas out the overflow tube regularly and you didn't mention that as a problem.

He's got the pumper carb, so no float cage like on the CV carb. I'm working to source the smaller O-ring for the other side of the float cage on the CV carb as an addition to my O-ring kit, but I don't have one yet.

Sounds like a great plan to me and the DR is more than adequate for the TAT (at least the section I've been on through New Mexico, Colorado, and Utah). I'd pull both swing arms off for a thorough cleaning/inspection/lubrication. If they've been well cared for (greased regularly), you'll probably only need to replace the lower shock bushing/bolt that is not greased. As for wheel bearings, I'd replace them all. Replacement kits from All Balls Racing are of good quality and include all of the bearings and seals (pretty inexpensive, too). High capacity gas tanks (4 gallons) would be a great addition for the TAT.

I'm looking forward to trips like that with my children when they get old enough :>

anyone the differences between the brake lines on the 90-94 dr350 and the dr350s bikes? They have different oem part numbers, my front line is shot and was looking at aftermarket lines. I imagine maybe the length is a little different with the same banjo connections?

[ADV BUM]

Does anyone know where I could find some? Would like to see price for store bought vs me making them.

THanks

[mwilliamshs]

Appreciate the input!

My largest areas of concern at the moment are charging systems. I know the bikes OEM part numbers differ but I wonder if one might fit the other in an emergency or as an upgrade?

I've spent several hours on parts sites comparing part numbers and here is a short list of what I've found so far:

FITS BOTH
oil filter: EMGO: 301701
Turn signal lens, amber: k&s 21534
clutch spring set: ebc: 382014
front sprockets interchange
clutch kit:ebc:384071

exhaust (from headpipe back anyway...)same
skid plate same
foot pegs same
push/pull throttle cables: motion pro: 040144 fits both
shifters interchange
rear disc guard fits both moose shark fin
air filters interchange
front brake pins interchange
front tires interchange
rear tires interchange
fork seals interchange
frame covers interchange
front fenders interchange
rear fenders interchange
rear axles interchange
both sides chain adjuster interchange
front caps interchange
front protector tubes interchange
front spoke sets interchange
front rims interchange
front innertubes interchange

Doesn't Fit Both
speedo drive differ
starters differ
front brake rotors different
rear hub different
front master cylinders differ
rear wheel bearings differ
clutch cables differ
front wheel bearings differ
shock bearings differ
rear rotors differ
front hub differ
front axles differ

Definitely more work to do but this list is more complete than I'd expected it would be by now. Seems most engine parts differ which was surprising. I'd been told they were the same except for the top-end. Also the clutch cables being different was a shocker and I think it might be as simple as one being about an inch-and-a-half longer than the other. If that proves to be true I'll just pack the longer one as the spare for the trip probably. Are the TW cables that much better? Seem to be about double $ most places. One of the bikes has a larger Acerbis tank installed but I'll most likely install the yamaha raptor petcocks in both bikes. Vacuum petcocks have never made sense to me and I've only known of a couple failures personally but I have no intention of fighting that battle in the middle of nowhere.

Guess you have concidered using two 350s, if the boy can handle it. Might need lowering. Don't think there's a lot of difference in size and weight. Power is a little different. 250 makes power at higher rpms, 350 probably has more grunt.
