Hardassfunk Posted September 7, 2019 Posted September 7, 2019 Just purchased as a lil project to use next year. Gsx750W fitted with MK1 B12 engine.Need a fuel tap so far. Anyone have any idea if there's an airbox that will fit with the B12 engine? 1 Quote
Blubber Posted September 7, 2019 Posted September 7, 2019 I think @Shilland @legolamb have done similar things. Might even have been @Fatmama If you search for inazuma you will find more information regarding this specific swap. Enjoy Quote
Duckndive Posted September 7, 2019 Posted September 7, 2019 they did build a 1200 Inazuma so I would guess if you can find one being broken the air-box from it would solve the problem Quote
Hardassfunk Posted September 7, 2019 Author Posted September 7, 2019 Thanks guys have done a search for inazuma rather than GSX750W and given me the info I need.Standard airbox and B12 carb to airbox rubbers should do the job 1 Quote
Shill Posted September 10, 2019 Posted September 10, 2019 I did the conversion this year with a mk2 B12 but went for dual pods with a stage 3 DJ kit and dyno setup. If I knew there was an easier way to get it running with airbox I might've gone for that as a first step and saved a bit of expense, but can't complain with the result, making a pretty useable ~115bhp. Cheesemonkey also did a mk2 and modded the stock airbox to suit I think. I was going to write up my project at some point - it's definitely more straightforward using the mk1 engine, I think the harnesses etc match up easier. You mention needing a fuel tap, if it's the clearance you need, you can space the back of the tank up a little and get enough room, it's barely noticeable. I understand people use a Fazer as a replacement in some cases as well. 2 Quote
Hardassfunk Posted September 10, 2019 Author Posted September 10, 2019 Thanks guys.I purchased the bike already converted.The fuel tap lever was broke thats why I need to replace it,looks to be standard Inazuma Fuel tap tho,tank never had any spacers to the rear and seemed to be no clearance issue I have read couple of threads and seems Inazuma airbox with Bandit rubbers works Quote

It was a bit of a nightmare! I'm afraid I don't have any good advice really for this, it was a pain in the arse - each time the engine went in or out it was me and two mates supporting it and trying to wiggle it back and forth to get it around all the right points, with lots of swearing (we did it twice because I wanted to check the electrics etc were working before I committed to drilling the frame). The new lump is taller so it is a bit awkward. My process: TAKE OFF THE BREATHER BOX ON TOP OF THE VALVE COVER! To get it out, removed the side rail, sat the engine on a trolley jack on a bit of wood, nudge it forward a little, sideways a little, until it comes free. To get it in, laid the bike on its side on some old sofa cushions and sat the engine roughly in place, then lots of back and forth to get it located properly. There was a load of it moving slightly, asking "Who's got the weight???" and the answer usually being it's caught on something and it's stuck. We also bashed the hell out of the coil mounts. I guess the old hands have a better method or knack, I don't know if the Zuma is more awkward than other transplants or if I just don't have the feel for it, but it was not an elegant process. Also we were in a small garage with minimal tools and lighting, so if you have a good place to work it's probably easier! Edited September 26, 2019 by Shill Quote
Hardassfunk Posted September 26, 2019 Author Posted September 26, 2019 Anyone have an idea if the airbox can be fitted with engine in frame? Quote
Shill Posted September 26, 2019 Posted September 26, 2019 I don't know for def so worth a try (esp with all other stuff removed), but I'm pretty sure it won't fit due to the depth of the box between the frame/under the seat. Quote

Thanks for the info I think I,ll go down the sump and pick up off, cam cover off and bare frame route.... Quote

That sounds wise I think - would've been way easier with more stuff removed and resulted in less scratches! Quote
