bruteforce

I've set my fuelpressure to 3 bar. Have the injector company told you at what pressure they test them?

If the emulsion tubes are loose, there must be a problem with the fitment of the mains. In my 34mm carbs there were brass rivets under the mains to make sure the tubes were "pulled" down into place. The bike ran fine before, why change a winning team if they're only dirty? I can get them ultrasonically cleaned for little money, no problem.

Why not try the ATEcu? Arttu has loads of experience with those. And it's a very good price.

No, it's a draw-through setup modified to EFi with the intercooler added to it

Hi Greg, See my new topic in "members" part of this site. Subaru unit is a plain bearing type turbo.

Great build, thank for sharing

Be warned though, don't just skim away as I found piston height to differ on gen one busa pistons. MEASURE

It's 1195cc guys cuz of the short-stroke crank. Needed to shave 1 mm off the top of the block to get decent CR though.

Pressure is not an issue as the oil gets pumped back into the crankcase, and the flow is also not very large. It needs to be able to withstand the heat of the turbo oil as a first priority.

Crank-end pump such as Emtes example didn't work for my bike- turbo too low as they hardly self-prime. I used the Facet electric pump in the end, bought two to also have a spare. Never needed it. You can place it anywhere as it self-primes. You will need a catchtank under the turbo as a fair amount of oil drips from it after shutdown, with the risk of overflowing the turbo.I made a vent on my tank so this can't happen.

Without. I've been thinking about this too, being that on a GSXR the rider is over the handlebars more than on a GS.

That's a top tip, thanks!

So if I'm correct the weight over the front will be about 108,9kg. I'll work from there. Forks aren't in bad shape at all, only the lower fitted adjustment screws are corroded solid. May need to replace them. What I am thinking of is buying an upgrade spring/oil kit from WP or other top brand, that is a little more affordable than bringing it to a suspension specialist to have it setup completely customised.

@KATANAMANGLER Sure, Just PM me your address

Hi boys and girls, Sorry for my late reply, I got sucked right back into work you know. A big thanks to all of the OSS crew, you are all great people and very hospitable to someone like me that you have never met before. We had great laughs and I learnt a lot. I was particularly interested in majortom and meanbean as they were running their turbobikes on the track. I actually have never thought of running it in another fashion than a straight line. I'm not really the motorcycle-racing type but if you put me in a go-kart I usually set all riders back at least one lap. This proves absolutely nothing except that I apparently know what racing lines are and probably should just have a go at Cadwell trackday next year on the TurboGS. (OR I buy myself an old Slingshot and have a go on that.) Now I only need to do some thinking on making the turbo a little more corner-friendly by providing more ground clearance and some crash protection maybe. Will defo be back next year!

As I have an oilcooled 750J/K front end on my TurboGS and would like to upgrade this a little, I was wondering if my 550 based bike is heavier over the front than the original GSXR 750 was. I do have a big turbo there but no fairing so it might out-weigh each other Has anyone measured what the real-life weight distribution (so I mean with oil and some fuel on board) is on a standard GSXR750 J/K?

Hi Gixer1460, I have the standard bolt-2washers-nyloc nut on each arm, and run fresh standard spec (coil) clutchsprings. This should be OK. I DO have a little notching in the basket as it's a 30yr old motor. In the meantime I have gotten 2 spare baskets that I'm dreading to put on because I fear whining noises from non-matching main gears.

Fully correct remark Mr. Gixer1460!

To report back to you, the clutch slipping problem certainly is a lot improved. Only did a couple of hundred miles on the bike so let's give it time to maybe get even better. Now I only get slip at heavy loads (boost) in 5th.

JK, I get the impression you haven't checked deckheight then, as the pistons apparently were touching the ceiling with the 1,5mm spacer plate? Any idea what actual CR might be? I would make sure of that so it won't blow up because CR is still too high...

If your header is slightly warped it will leak at the gasket again. I'd check that again first to be sure. I'd then take the camcover off just to have a look if there are no loose tappets (if any), if OK then pop the sump off to search for debris.

Yeah, I always take too much stuff with me but then I'm rather taking a set of dry clothes too much than walking around wet... Apparently I will get a small feature in augusts' Practical Sportsbikes magazine. I was spotted packed like this with a clearly "ridden" dirty bike. They were surprised that I got there on the turbobike "all the way from Holland"- it's only 100 miles guys, the rest is done by boat....

Ready 4 Cadwell! TurboTouringMachine

Camtiming one tooth off?

yes was calibrated at install, worked OK before and works OK again now
