- Hola! So this Dr350 is taking a lot to get road worthy. Switching the carbs out was kind of like eliminating one more possible error for me. The one in the bike when I got it wasn't awful but it definitely wasn't perfect. Make sure to subscribe to see the rest of the Dr350 Build!!

just bought a similar bike. My first bike and first project. Excited for whats to come and thanks for the Info
Good luck and have fun!!
@@RidinDad how’s she runnin now ? You still have it ?
The make getting old, stiff rubber boots back on the carb really easy, here are a few tips: 1) borrow your wife/girlfriend/your hair drier and gradually warm up the rubber boot for 1-3 minutes. Do not melt the boot, just get the entire boot warm and it gets nice and flexible. Then mount the carb. 2) as a smart extra step, add a tiny (supper thin) amount of silicone grease to the inner surface of the boot where it fits to the carb. Silicone grease will not attack the rubber and will last a long time. The thin coat of silicone grease makes it another 50% easier to get boots on or off. 3) smart mechanics always use both warmth and grease. Easy-peasy, no fuss, no muss.
Good tips!!!!! I have sold this bike a while ago and honestly don’t plan on getting another carbureted bike anytime soon lol
Great video, I have a klx 300 with a 331cc big bore kit that I installed this carburetor, mine is a tm33 bored to 34mm by b&b cycle restoration, it has made a big difference in throttle response coming from the standard cv carburetor!
Nice!!!
I just bought a 94 Dr250 and I'm doing the same thing with it. I got a whole kit from Mike at PowerBarn and I installed it just yesterday. Mine needs a bit of tuning since the kit is set up for the 350. I think my accelerator pump isn't adjusted correctly, because when I quickly open the throttle it just bogs, and if I hold it it dies. Slightly slower throttle twisting and the bike sounds good and mean. Can't wait to dig into it this afternoon.
Awesome man!! Happy tinkering lol
I’m doing my 90 dr250 now and am having g the same issue you were. What was your fix to stop the bog and get a quick response throttle?
@@Alawicous The accelerator pump on that carb is non adjustable. In order to tune it, you'll have to either get an adjustable rod, or get creative. My bike had issues after about 1/2 throttle maintaining steady rpms, so I ended up selling the bike after a couple months of frustration. I believe that carb just provided too much air at higher rpms to properly regulate fuel for that engine. I would've rather spent more money and got a better overall bike than continue to mess with that one. That's exactly what I did, and sold the dr250 lol
@@TheGamersRace I have had this bike for 10+ and just decided to rebuild the carb and since that it’s been a thorn in my side. Before that the bike was unbeatable and extremely dependable. Now I’m contemplating selling this and my Z125 for something else. UGH!!! What did you end up getting?
@@Alawicous My original carb on my dr250 was damaged, so if I had that option I would have gone that route, but it wasn't really repairable so I tried doing the carb swap. Now I have a tw200 and a dr650 for on and off-road, and a crf450x with a street title, but only so I can jump between trails. It's not very good on road.
A pumper really wakes em up, especially with a cam n pipe. I put a CV pumper from a Nighthawk 250 on an 86’ XR200 and boy what a difference.
Yeah I heard so many good things about the pumper. Unfortunately that wasn’t the issue and it already had the pumper on it anyway. But that bike is gone. Way too much of a hassle for sure
@@RidinDad yeh you can only dump so much $
That was my issue lol. Probably could’ve got it running pretty good for pretty cheap in the long run but it needed all new seals all around the engine because oil was leaking out of everything and it had been abused so it just wasn’t worth my time
NOT sure if this is helpful or not, but wondering about the issue with the float bowl screws stripping is the need for using a JIS screwdriver instead of a standard Phillips? Recently learned about these and had been using Phillips and stripping screw heads for years.
Yeah I have a JIS
Do you not need a manifold spacer for yours to fit? I bought the tm33 kit before and it included a cnc machined spacer but I remember when trying to install it before it was a major pain and a tight fit unlike stock vacuum carb which has space to come out. I'm gonna try getting that carb going this season cause I think I finally mastered jetting my stock carb to my exhaust and airbox mod.
Yeah there was a spacer/adapter that is in there. And you’re right lol there’s barely any space for it to come out. Huge pain!!
Well heck, switched out pilot to 40 and main to 140 on mine. Runs like crap. Will try to switch the pilot back to the 37.5 and see how that works. Backfires like Wednesday morning after taco Tues...
😂😂 that sounds like some serious problems
Bout to do install, I do not have the spacer with my tm33 carb sadly. Gonna throw some cardboard cut for mean time if not tight within boot. I’ve rebuilt top end to a wisco 385cc bor up, any suggestions for tuning before rippin my hair out?
Not at all man. Sorry lol. I had this bike for a very small amount of time
just bought one for my xr250r 1996 cost me 291 gdp pounds had to order from mikunioz but happy days
Should be a nice upgrade!
@@RidinDad hopefully for the price was paid haha
😂
@@RidinDad I’m here again and yea carb is amazing does need to be set up tho
Sweet! Good deal man!
I’m thinking about getting one of these, did the adapter come with it or did you buy it separate?
It came with mine because the car but was already swapped when I bought it. But you will have to buy it separate I believe
did the same swap, did you have to rejet? pilot is 37.5 and its a bear to start. It will start if I hold throttle 1/4 to half but shouldnt have to do that...
Mine never had the stock jets on it & it had a bunch of other issues so I just sold it as is. Never got it truly running good so I'm not sure what jets would have been most appropriate
Hi great video. What's the part# for the carb and where can I get one?
I don’t remember the part number. It’s been a while. I believe I stated where I bought from but I didn’t I apologize. I don’t recall the company either.
Do you know of a carb that will replace a Mikuni 42A21 pumper carb on a 1987 Suzuki DR200? I've been told since I just trail ride that a CV would work?
I mean I think it should? I’m not a carb genius. Only know what I know from this bike and from reading a ton of forumns and stuff. Pumper carbs generally have better quick response for the throttle which is what you’d want more of for off roading. I would stick with a pumper personally. How come you wanna switch?
@@RidinDad I bought the bike used and the carb was apart in a bag, very dirty and missing at least the pilot jet....I don't know if this matters but I finally got it cleaned and its a 42A20, then inside the bowl there is a K ? From what I have read and the pictures, its supposed to be a 42A21 so I need to figure out if this is the original carb or not now....smh.
I hear ya man. If you do some forums searching you should get the answer. I don’t have any better answers for you unfortunately. Just my opinion to stay with a pumper carb for sure though
@@RidinDad I plan to...found the jet I needed...can't wait to hear it run!
Good luck man!
Got 91 Dr 350 s can't find carb do u no where I can get 1 thanks
I do not. Sorry. I’m sure if you google enough you’ll be able to find either an oem one or aftermarket
@john andrae Did you ever find a carb for your bike im also looking for a replacemnt i have a 1990 dr350
where do the clear tubes go
To be completely honest man I don’t even remember anymore. I haven’t had this bike in About a year and I have no idea. Sorry man lol
@@RidinDad okay thanks
what adapter are you using?
Not sure. Came on the bike when I bought it
@@RidinDad do you know whare i can buy them i bought the mikuni but i dont have adapters
I do not. I’m sorry
@@yarin5952 check eBay I got a adapter set for my dr. It came with a peice for the street bike as well so you don’t have to switch air boots
