Ok ok, before you think I'm crazy hear me out. A company called Ecotron offers a universal EFI kit and small engine turbo. The EFI kit has been fitted to a DR650 before, so I think it would work with the TE610. The company offers the turbo, along with an oil pump, oil cooler, and accessories such as flanges and bolts and whatnot, so my idea was to tap into the TE610 external oil line that runs from the bottom of the engine, then run the oil through the pump, then the turbo, then the cooler. If there's enough pressure maybe I could add an inline oil filter as well. Then the freshly filtered and cooled oil resumes the normal route and dumps onto the crankshaft. By using the engines oil, I would be able to cool it, filter it, and increase the capacity, which would be a huge improvement over the current setup. Ideally this bike will be a daily driver and I've read how hard that can be on this engine. I have many concerns about my plan, number one being whether or not I inhaled too many gasoline fumes yesterday disassembling the TE610. Number is two the dual exhaust and it's turbo compatibility. Obviously adding two turbos is insane (as if adding one wasn't already ridiculous), so I would have to plumb it in where the two pipes combine, but I'm not sure if the single pipe diameter is small enough for the turbo. Another concern is the compatibility of the plumbing in the oil pump with the engine and it's power consumption (not to mention the power consumption of the ECU). The oil pump draws 1.3 Amps, the ECU draws 2-3 Amps I believe, which would be a draw on the stock stator. But if I use all LED lights then perhaps it is possible. Something else I'm worried about is the size of the throttle bodies. Ecotron offers an EFI setup in 38 mm and 42 mm throttle body sizes, but I'm sure this could be remedied with an adapter. If turbocharging the bike ends up being as ridiculous and unfeasible as I think it will be, then at the very least I would like to look into the possibility of adding the external oil cooler, pump and filter and possibly still the EFI system. I've done some research, and while I can't find anything remotely like this, I have found quite a few threads talking about adding external oil pumps to the old pump-less huskies but no-one ever seems to go through with it. I'm willing to be a guinea pig, but I'm not going to attempt something that might be theoretically impossible. Here's some of the threads I found in the research: http://www.thumpertalk.com/topic/729425-electric-oil-pump-on-a-husky/ http://www.thumpertalk.com/topic/291552-tc610-everyday-use-no-oil-pump/ http://supermotojunkie.com/showthread.php?89243-Adding-an-electric-oil-pump-to-an-older-Husky And here's the Ecotron EFI kit and turbo: http://www.ecotrons.com/products/400cc_to_800cc_engine_fuel_injection_kit/ http://www.ecotrons.com/products/small_engine_rhb31_vz21_turbocharger/ And here's the EFI kit on a DR650: View: https://www.youtube.com/watch?v=n8tvQ42DIvY I should mention that I also own a DR650, so worse case scenario is I could swap the EFI system over if I can't get it to work. Lastly, this is all a lot of work, time, and money, all headed towards the primary objective of extending the life of the engine (which sounds counter intuitive since a turbo is being added, but is accomplished through oil capacity, circulation, filtration and cooling). One option that should always be considered is at what point would it be smarter to buy a newer Husky engine and adapt it to my bike? Not only would I get the newer technology but I could have an electric start too. However, I've had problems locating complete engines online.
I'm very familiar with the ecotrons fuel injection on dr650s. I am a moderator on drriders.com. I'm not familiar with the turbo however. The ecotrons has come a long way from the beta version that we helped finalize. MXROB was a big key in making the big bore ecotrons systems work. I wouldn't hesitate on the fuel injection but personally I think a turbo would end in frustration and disappointment.
My AJP uses a Dephi system that is semi universal. Manufacturers buy the stuff, program the ecu's and make lots of adjustments for their needs. I have to say I am VERY please with the performance and running. It is nearly perfect, no glitches or stalling or any issues at all. Runs fantastic bottom to top. It's as good as anything else I have tried and better than the Mikuni stuff by a long shot. Cool tech out there these days. http://www.delphi.com/manufacturers/other/powertrain/small
Sorry but this is way over complicated. No reason for EFI, just purchase a large lectron carbuerator and run the turbo outlet as close to the intake manifold as possible. Suck through or draw through carbs are very very very very easy to tune and will make 70-80% of the power that the efi stuff will. On top of that you get the intercooling effect of the fuel being atomized into the turbo cooling it. No intercooler needed if you run e10 or e85. Tuning is simple jet swap or needle adjustment on a lectron. You could do this quickly and it will be awesome. The only thing holding me back is the fact that honestly I dont need a turbo on any of my bikes, and it would shorten the reliability of the bottom end while adding weight.
Judging by your guys' responses, maybe I'm not totally crazy after all Hey! I'm familiar with MXROB too! What a legend. Would love to get my DR650 going on EFI too. I'm definitely on the fence about the turbo, my main concern being the adaptability to the Huskies exhaust. Oh cool, I tried searching in the vintage section but couldn't see it anywhere, was it any of the ones I linked? Interesting! Did yours come with a crank sensor? Over-complicated is definitely something I'm worried about with the concept, and my aim is to hopefully make the bike more reliable, rather than more powerful. So I'll probably nix the turbo idea and stick with just the oil cooler.
the KABOOM factor and ability to get parts for the hoosk would tell me no... if you have the funds to do it right, it would be a fun project on something more common. alot of stress on a single tho. and it wouldnt be worth doing for a 10hp gain.. i bet doing a setup with the lectron would rock and sound sweet..the external powerjet adjustment would be a godsend
I had lawn mower with a dodgy carby when I was a teenager... I tried to "fuel inject" it with a 12v battery, the windscreen washer assembly from my car and bits from a spray bottle for the "injector" It ran for about 5 seconds then flooded hahaha. All in good fun
I've heard quite a bit now about this lectron carb, I visited the website but couldn't get any solid information on the advantages to the carb. But I'm not too worried about power gain, I think the bike is powerful enough as-is, but I would definitely like to add an external oil cooler/pump if possible to help the reliability. Haha that sounds like an awesome project, I wouldn't know where to begin starting from scratch like that.
in a nutshell, no jets to replace, only 2 circuits, accuracy, clear float bowl, mild to moderate increase in economy, externally adjustable "main jet" circuit, taper bored, increased top end...there is a slight loss of bottom end "hit", most riders that arent into supercross welcome this, there is virtually no overlapping of circuits so carb works very cleanly. hard to describe but it was kind of a motorcycle zen moment for me.
Interesting, sounds like the cost/benefit ratio greatly favors the lectron, installation sounds a lot less intimidating than EFI as well. I'm still interested in an oil cooler setup, but wanted a bigger capacity than the cooler ecotron offered, so I started looking on ebay, but all the motorcycle coolers were surprisingly expensive, or very low quality/capacity. So I started looking for atv oil coolers, which had a much better selection. Finally I settled on a Honda TRX350 oil cooler at a good price and a size I was happy with. I did, however, purchase the oil pump from ecotron because it was a reasonable price and had a good flow rate. I haven't decided on the oil filter yet. All my searches for an inline oil filter brings me to inline fuel filters. Also, my plan is to implement both oil pressure and oil temperature sensors in the external oil addition, so ideally the oil filter manifold would have taps for these sensors, but I doubt I'm lucky enough for such a thing to be on the market. Ideally I would get the bike back together in stock form, run a flow rate sensor on the oil line and get the data. Then install my oil pump, filter, and cooler, and get new flow rate sensor data and compare the two. I'm going to look into sensors to see if I can find a reasonably priced one. At the very least, I intend on adding a section of clear vinyl hose to the oil lines by the oil pump, this way I can ensure that oil is indeed flowing. The clear vinyl hose is extremely temporary, however, and the bike will not be allowed to reach very warm temperatures, simply a proof of concept.
Plenty of aftermarket oil filters for Classic British bikes which normally only came with a bit of gauze! I have one on my TriBSA
Awesome! Thanks stormer254! Those were some pretty serious homemade modifications on that first motor.
Just got the oil pump, oil cooler, and new fork seals. Full steam ahead! Now I need to get the oil filter and I think I'm going to install a one way valve so that the oil pump and filter stay immersed in oil. Also still need to figure out how to get an oil pressure/sensor in there.
Has anyone here rebuilt a bottom end? I'd love to get in there while I have the bike apart, but it's very intimidating.
Great reply. MEGA - If you get interested in a Lectron more give Kevin a call at LEctron, he has decades of experience with all sorts of weird installs. I'm sure he has seem many a turbo bike and will know what it will like.
