    DR350SE transplant questions

    Quick question for you guys. The motor is strong as heck. It's almost broke in, I'm starting to go on 30 min rides at lower 4000 to 5000 rpm. I'm hitting 60mph easy at 5000 rpm in 6th. The question is the sound. It just sounds very gear driven. My 650 didnt sound like this however it wasn't electric start. I'm wondering if it the extra gears meshing making this sound. It almost like a 350 Chevy with a gear timing set. Do you guys have this out of your DR? I've tried to find YouTube videos of DR350se motors but as luck would have it a lot of sound is washed out. Tomorrow I'll try to get a video with a good sound clip.

    That 450 was made so easy. If you get with Mark over at Kustom Kraft he knows these motors well. He shared what parts he uses with me and they are a lot of the parts I use in my 3.2 mile road coarse car, so i know it will take a beating. He even offered me a JE forged to Weisco forged piston. I run JE in all my cars so ih was happy with that. The sleeve was done perfectly, I couldn't find anything to complain about. He provided his recommendations for breakin. I didnt have to clearance the case or anything. Just install as normal. I've ridden a few dr350s and this woke up that motor. I'm sure there are other big bore kits out there but I have personal experience with this company. Not to mention I never saw the barrel I sent him because it was just some used one on Ebay. He checked it out and let me know it was good to go. He did the work, let me use pay pal and then he even shipped it to my deployed country. No many shops will do that because it's a pita with forms and such. I've already sent him other jobs from here.

    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.

    DR350SE transplant questions

    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.

    '98 DR350SE won't start, help :)

    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.
