Turbo oiling problems

OK, ive got a gs750, with 850 barrels, fluid clutch , usd's n monoshocked etc etc.
More mine than suzuki but c'est la vie.. Next stage in the transformation is underway but is proving problematic. I need to supply a nice steady suppy of oil to the turbo at about 40psi, and the gs is a low pressure high volume system, I want to piggyback another oil pump onto the motor and use it to pump/scavange the turbo, ive tried electric oil pumps n stuff and theyre just not practical for everyday use. Already got a high electrical load with the fuel injection fuel pumps n stuff ive rigged up. And to be awkward I'd like to keep the starter, heart failure sets in trying to kick it over, just cant get the speed into it when the oils thick...
Anyway, anyone done this? if so, what pump did you use to achive it? where did you mount it to take the drive off the motor?
Any help gratefully recieved.
best regards.

Geez, and I thought my GS was a stripped down bike since I stripped 60 pounds of it!! :lol: :lol: :lol:
You don't even have a front brake on it!!! (just kidding, good luck with the project).
 
brakes

I thought I could stop with just the engine braking 8O
Actually theyre off because Im making a adjustable mechanical antidive linkage with some monster calipers...
Pic from 97 , old gs's dont die they just keeps evolving...
 
That is one interesting project you have going on there! I would suggest one of the new variable vane turbos that do not require an outside pressurized oil source.

Cheers for the suggestion hap, but the aerodyne's and the like are way way way over what I would spend on a single part for this project. Total project cost to date is under ?800 (bout $1000), including purchase, and thats been spread over 6 years or so. I cant bring myself to blow ?3000+ on one part. Im thinking now about machining up a blank plate for the alternator side, and driving a mechanical pump from a car + a belt drive to a alternator from that side, but I'd still like to keep the starter clutch, dilemma's dilemmas eh? :roll:
 
Since I don't know anything about turbo's I can't comment on that but why would you build an anti dive unit for the GS when there are several GS models out there that have it and maybe you could adapt it to yours. Unless as you stated about some other part it is cost prohibative.
 
where did you get your headlights?? I may have to do some juggling if I cant fit the clip ons above the top triple on my GS (89 GSXR1100 front end) . I was hoping to keep the stock front fairing to keep the costs and labor down but maybe I should just get a late model front fairing and fix it. then modify to fit but like I said labor labor labor. anyway that would necessitate the new headlights. either way I would like some sources for headlights. I am partial to the twin units. they could look grat in a R6 or R1 or CBR fairing. ahhhhhhh but I digress. thanks and any info would be great. :twisted: :wink: later, tome to ride.

hlights n antidives

hlights n antidives

Jay: Im building MECHANICAL anti dives,
1) because they look cool and work reliably (although my other project has electric anti dives from a gpx600r that run off the brake light switch, so reliability isnt really a issue)
2)because no one makes anti dives for white power usd forks like I have (theyre about 8" over stock lenght of the gs forks).
3)The only way to have twin discs up front is to have them mounted on the anti dive arms since there is no brake mounts on the left leg as standard, and I didnt fancy welding them on. And Im sick of trying to source a right hand fork leg lower for these forks. Hope I dont bend em stuffing it into a hedge or something.....
4) Why not :D (I think this applies to most of the bike!)
Re the lights, theyre off a aprillia of some description but they take the large bosch style bulbs that come in 6v and 12v variants, so both dip and main unlike a lot of the after market setups that just usually give you one light for high and one for dip.I had some "streetfighter" units previous to these and the light was rubbish, and the build quality was appalling, often at journeys end you would find the bulb in the bottom of the lens the fit of the holders were so bad. Same deal as all those "custom" rear lights...
Theres just a small alloy bush spacer between the two units and theyre bolted solidly together .Theyre mounted to the top yolk (english for triple clamp I think) by some (robust!) homemade brackets. You could get two lights off pretty much most small bikes that have a headlight bowl and bolt them together. If you pick bosch type bulb models you can pick and choose your bulbs from a specialist bulb supplier. If you go that route, dont forget to go overboard on the brackets, theres nothing more annoying that riding at night with your beams bouncing round because of bracket flex, and your mates will hate you for it too...
