yeah, Inazumas are fun. check the Tank, the 750 have tank rust issues and the tanks are the hardest parts to source, near unbtainium. France and Germany have biggest communities and forums for them welcome to oss.

found the perfect fitting one for my 1980 gsx1100e in Germany, like the sporty lines very much.

the 750 Zumas are known for tank rust, that could cause your float needles to stick open / not close completely. Check for tank rust, do you have a fuel filter before the carbs? You should find original spare carbs, as the 12 and 7.5 using the same. About airfilters... with airbox and stock exhaust headers the Inazumas are very picky about airfilters. Must fit OEM airfilter (with the foam)/ airbox / headers to make them run properly, or else require Dyno time.

Found a New Old Stock Giuliari seat on that site in red to replace the torn original seat, makes it faster imho. Also played with the lid of the airbox. First replaced the deteriorated original foam, just to find she didn't like that at all. The removed the lid completely and now she revs out nicely. Touring two up thru Austria again ATM, apart from two lost and replaced header bolts, she's faultless. Gonna need source a heated garage to dig deeper thru the winter and try the newly arrived 530 chain set with longer gearing. cheers

Have a couple Inazuma 12s. The pump is needed to empty the reserve. Without the pump the reserve is pretty much left in the tank.

Looking at jt sprockets site i found front ones for Hayabusa and Bandit1250 fit, the rear ones from the oil boilers; havent installed yet, so not 100% sure.

new rubbers are on, first time running Kendas with inner tubes on a road bike. Head bearings replaced as well, made the steering much better. She got the original airbox, gave her a new airfilter in hope she would run better as there's not much after 5000rpm and above 6000 it's terrible and revs only with great reluctance. from the oil boilers I know they won't run well with aftermarket airfilters in the airbox... anybody knows if that's similar with the aircoole engines? Because I didn't get a OEM one and I think it's either that or timing or what else is common to these engines that causes them not to fully / clean rev up under load? Will try without the fuel filter next. Any input is greatly appreciated. cheers

all ok, figured it out... these old ladies got some new (to me) tricks lol guess it will slide out easy now with these end things removed.

currently in the process of rear wheel removal to fit the new rubbers... The rear axle is on same height as the left side exhaust... is it really necessary to remove the whole exhaust to get the rear wheel out? Or maybe the foot rest assembly can be removed to allow the exhaust enough wiggle room to get the axle past it?

Returned to Europe after 17 years of Asia and was welcomed at a friend's home in Austria where he kept a gsx1100e I bought unseen 9 years ago. The bike stood in a shed for all these years and probably a couple more before I that. My visit to Austria was originally to restore a slinghy that I left with friends in Switzerland after my last holidays back home and was in need for some tlc. On first look the gsx appeared quite complete, but in barn find state... seat torn, back brake stuck, front brakes not working, tank has some damage in the red-orange paint, mainly around the lock, and a good amount of rust sprinkles all over her. ...and that hiddeous front lamp in 70ies TV design... ...it was love at first sight. Pulled the carbs off and threw them into a ultrasonic bath, new battery and she started back into life. Rear brake needed some fiddling, but finally unstuck. Front brake master was exchanged to a gsxf part laying in my friends parts bin, forks and shocks arent leaking (yet), changed brake fluid, passed Pickerl ( Austrian MOT), insured and drove her 1200km from Graz to Zurich and back to install newly arrived head bearings and airfilter. Today checked the valves, needed minimal adjustment, cams are all good. Tomorrow she will get new tires (old ones are 15 years old lol) and some fresh oil. It's a great bike to work on and there will be further improvements as time and money allow. the GS and the gsxr fighter are my mates, he's nuts as well lol.

Busa pistons ordered. Fuel return hose need check up. Thanks for info, updates once my mate comes for a visit again with the new pistons.

Yes. And hi.

Great, thanks @Duckndive

Looking forward to see this project. Just came back from a 3 day tour with my 12. It's no comparison to any blandit, have 2 x 1200 Inazumas and had a b12s bevore, that's now parts donnor.

Not bland at all, rather like that one.

Agreed, that's why i would stay with the originals. My 40's ran surprisingly well, mid and top range. Contrary to everything read here. Guess i was lucky.

@Gixer1460 OK, thanks. Highest boost I seen indicated was just under 0.5 bar at about 6000 rpm. According to proboost the kit should produce a maximum of 0.8 bar.

Inazuma 12 swoping the original 32mm Keihins to 40mm Mikkaroonies from gsxr 1100... Been there, done that. It works. Question why would you do that? I did it because i changed damaged headers to unrestricted, stepped headers from Holeshot (Dale Walker) and with them i wasn't able to dial in the original carbies. In retrospective i should have just gotten another stock header and done. The Ina 12 in standard trim got best low down torque from all oil boilers... My working set up was: Airbox removed 4 metal mesh pod filters Mikuni 40mm from a gsxr 1100w with their intake rubbers (can't remember jet sizes) Standard engine Unrestricted exhaust system with stepped headers. No fuel pump. (tank wouldn't fully empty anymore but no biggie) Inazuma 750 doesn't have fuel pump, the 12 needs a pump to empty its tank. She ran and sounded fantastic (loud as hell) with that set up, but is changed now to flat slides. Good luck and have fun with your Inazuma.

Boost gauge is a decent glycerin filled one. Yeah, boost is obvious, was just tricky to watch gauge, and rev counter on public Thai roads. Can altering BOV setting reduce max boost or does it just influence turbo spool up time?

Absolutely stunning work. Wet dreams stuff. Following.

@clivegto Thanks, will do that. Project will rest for remaining of these holidays. Next holiday new luck, will update what we get with turbo pistons. Cheers

Merry Xmas friends Sitting in a garage in Thailand and trying to get a Proboost turbo kit working on a Inazuma 1200 (same set up as blandit 12). Looking for information on how much fuel pressure should be coming thru the malpassi regulater. Currently 0.2 bars fuel pressure at idle. Bike kills pistons between 6000 and 7000 rpm (see pics). Boost gauge indicates between minus 0.5 bar at idle and 0 bar boost at pistons killing rpm. Scratching heads. Any info and ideas appreciated. Cheers and sawasdee krup.

All Inazumas 12 do have 32mm Keihins. They go well with airbox. Torque wave riding. Best rubbers are for any of the 40 Mickeyroonies. Inlet tracts must be grinded to suit the bigger rubbers.

Sad to hear Magni died. Very special bikes indeed. Even smaller then the gsx1200 Inazumas. I contacted Magni a couple years ago about an exhaust system, they will do, good people to deal with, but my bike went more towards streetfighter then cafe racer.
