    DR350SE transplant questions

    At this point in the game I'm now in the break in of the motor. I was running it at about 3k for 10 to 15 minutes then cooling down for a few hours. I would check the plug and then do it again. After about 3 days of this I started to get into the power band of the 450. WOW! If you want more power from the DR350 the big bore kit is the way to go. I started with a 48t then the 44t then the 40t now I'm settled at a 38t rear and a 15t front and it will just power wheelie 1st and pop up on the shift to 2nd. I found a chinese 125cc 6speed gear indicator, mounted it and spliced in the wiring. Now I have a 1-6 display working. I'm currently running 2.5L of oil but have the capacity of 3L. The oil cooler doesn't even remotely get hot just a little warm. But I havbt beat on it yet either. Loving this motor swap! I think with the new gears it will cruse at 80-90mph no problem. I also have a early DR250 bottom end I've been looking at building for the better transmission ratio.

    The CDI I picked up has a programable timing curve. That being said, ill be sticking with the stock settings for break in and see if it needs be be more aggressive later. I finished the wire harness with all the stock plugs. After butchering the 350 harness I was able to match all but 2 wires. This way I'm able to start a wiring diagram that will be easier to follow as the chinese were not consistant among bikes. We have 2 of these bikes and I found that the color codes don't match at all.

    DR350SE transplant questions

    Ok, now I have my stainless exhaust built. Unfortunately I had to use the crappy stock Chinese muffler because my perferated stainless pipe got lost in London somewhere??? Oh well I will mod the muffler to breathe a bit better her after break in of the 450 big bore kit from Kustom Kraft. The cdi is hacked in with crazy lose wires going everywhere so I'll need to build a custom wire harness tomorrow. (Happy Veterans day BTW) and hook up the gas tank with filter. But it runs. And it runs so well! I have a 32Tm with +3 main and +2 pilot. The starter is weak but it's a knock off. I'll have to get a much better starter and battery. I know it a heap, but I'm working to make it look as stock as possible. The police are so corrupt here that if they see it has been modified they will try everything to take it and make it their own.

    DR350SE transplant questions

    I agree about they DB killers being junk. I took the principal of using chambers and fiberglass matting for this one. I'm almost positive that I will grind it open or plasma cut a door in it to modify it. I just have to keep my mods annotated so I can build another one next year. I figure building one every season not only give me a way to kill some free time but to keep the same basic design and perfect it with the experience of a season of riding. Also since it gets 45c here its way too hot to ride so why not spend some time on the welder in my makeshift shop, after all I spent the entire summer tearing down the motor for rebuild, big bore, head work and powder coat. Then I have to create the motor mounts and mod the wire harness. The last thing to do is the CDI. The new digital CDI I bought says that a kickstand defeat wont work so I now have a stock DR harness and a kickstand switch to splice in.

    DR350SE transplant questions

    Thanks, I know the 350 likes a little back pressure to get the most out of it. I have a variable flow flapper from another bike I have been working on how to integrate. However at the end I may just make a low profile downward facing disc style like the super trap. I don't think just the muffler alone will provide the reverse pulse that I need. Now once the perforated pipe arrives I'll have everything I need to give it a try. All that being said I still need to receive my 350SE CDI and figure out what wires I 100% have to make connect and what wires I can defeat because the donor bike doesn't have many latched safeties.

    DR350SE transplant questions

    Well, the oil tank is complete. However the location I'm at it took me a while to get argon for my crappy DC TIG welder. Once they had the 10m^3 it was $1200. I was thinking of all the cool custom stuff I could have ordered for $1200. But what is the fun in this? This entire project was to kill time until I return to the US, so i guess its worth it in experience. Now I'll make the underslung 3 pass type muffler. That wont be near as tedious as the oil tank. I must have filled that thing 20 times with water till it passed the 2hr dry paper towel test. At it sits it will hold 2.5 liters at mid sight glass level. Then it will have all the hose and oil cooler volume as well. That DC TIG is hard to get use to after using AC for so many years.

    I think the oil tank can sit nicely where the stock air box was under the seat. I will use a couple of baffles in the tank and then put in a oil catch can as well.

    That's what I'm thinking. There is not a lot of sitting still so air would be rushing. With a thermo switch I can make it automatic and would only come in when things really get hot. It's still in the build phase so it might or might not happen. I'm running a decent gel cell battery and all lights are LED for the lowest power draw. I'm modifying the neutral switch to display all 6 gears. The stock donor bike had this capability. Today I'll break out the plasma cutter and cut up my oil tank parts and the sheet metal for the custom muffler I want to build that hangs under the bike line a buell silencer.

    DR350SE transplant questions

    Thank you for the diag. I think I have a rough draft completed for the oil tank. It will be slightly higher than the head of the motor. I have 2 -8AN lines from either side of the tank combining to a single -8AN fitting going to the oil pump. This way no matter the motorcycle position it wont lack oil. I havn't planned on it but I'm kinda liking the idea of a fan on a thermo switch. I just don't know how much my battery/ DR stator can push on a short ride. I can go almost across the entire country in a few hours at 80mph. Lol

    DR350SE transplant questions

    My harleys use the same type powdercoat. It's a 50/50 debate on it. I like it and have pwdercoated a few back in the early 2000s. The oil cooler I have is a 10 pass type which is a lot bigger than than the stock dr350 or even the dr650. Fingers crossed on it being here as the heat does get 120s here. This motor wont be pushed as hard as it would in the dirtbike as it's all flat land type roads. I'll be sure to get a oil temp gauge for my tank and route it up to the controls to keep an eye on it.

    No you dont add 80/90 to the oil. You put it in the sparkplug hole. This will seal the rings/ piston, just long enough to get the engine to run. I would not try this as your compression check will tell the tale for you.

    '98 DR350SE won't start, help :)

    One old school dirty trick was to put a bit of 80-90 gear oil in the cylinder before the buyer gets there. This will bump the compression enough to get it to run. I am in no way saying that this happened but I've seen it done on old cars, in fact my dad and I had it happen to us. Once it starts it will run but has a serious lack of power. It puffs out some smoke like it has old cracked valve seals. If I were you, don't jump to any conclusions, just check your cold cylinder compression as that is the easiest thing to do. If you see you have compression then do the valve adjustments. If your using starting fluid it should be very easy to light off, just be careful as too much of that stuff can wash bearings. Also if I recall the SE model has a kick stand safety switch.

    There are all kinds of tricks to get a motor to run for a very short time. Not saying you got duped, just saying there are shady people out there. All in all, if the motor has air, fuel and spark you should get at the least a different noise out of it when kicked. Not knowing how strong the kernel of the spark is and the compression of the cold cylinder, it will be hard to say if it will run.

    You will need to check the valve adjustments. It wouldn't hurt to go to the auto parts store and get a compression gauge to see if the motor is even capable of lighting off.

    DR350SE transplant questions

    Hello, I'm new here and have been searching google images for good info for my DR350SE transplant project. I understand that its not a true DR however I have had a DR650 for some time and the DR platform just cant be beat for the type of environment Im currently in. The area I'm deployed to doesnt really cater to bigger motorcycles. In fact the largest cc for sale here is a 150cc. I have a Chinese knock off of a Ninja 300 that I bought new. The little 150cc motor just didn't have the kick I needed so I went to my old favorite motor the Suzuki DR. My first choice was the 650 however I dont thing the frame will hold up to that kind of power so I found a 1996 DR350SE. I rebuilt the entire motor/ transmission with new bearings and seals. Did all my powder coating and reassembled. Now that the motor is complete and custom motor mounts are built I need a little help with oil line routing. The obvious issue is that I dont have a DR350 frame with in frame oil tank. So this led me to start to build a under seat oil tank. As far as I can see there is a supply that is at the oil pump at the bottom of the block and a return then the vent. All my lines will be custom made using -8, -6 and -4AN fittings the oil tank will have a vent that uses a catch can because the vent wont be as high as the DR frame tank. Does anyone have any drawings of the oil lines and offer any advice as to what I may be missing as far as oil goes. I also have a larger oil cooler than stock to help shed some extra heat. Once I finish the oil I will be onto the CDI. I bought a 1994-1999 CDI unit that is digital and a kickstand safety switch to adapt to my bike. I have a larger voltage regulator that can be mated in to ensure I have plenty of usable power to run all the lights and such. The exhaust is still being worked out. I'd like to run the stock pipe but I picked up an older supertrapp that might get put on just so I can tune it for the type of driving I'll be doing which is short to medium roads that are not in the best condition which is why I went with the continental trail attack tires.
