Hi all, first post here, wanted to share some progress on a current project and check if there’s anything I’m missing. I’m putting a mk2 B12 engine in a 2001 Inazuma. I'm new to this kind of lark so discovering a lot of stuff as I go along.
Current plan is:
Mk2 engine, PAIRS removed (thanks to previous owner)
Hydraulic clutch off the B12
Mk2 carbs
Original Zuma 750 loom and CDI (I have the B12 ones if needed)
K&N ovals (+ jet kit?)
Exhaust tbc – bought the B12 headers and may try to re-use the 750 link pipe and can if they will match up (the 750 has a Blueflame can)
Tank raised a bit with spacers at the back, or pingel tap for clearance
Need to drill out the 10mm mounting holes to take the 12mm mounts
Electrical stuff – so yeah I didn’t appreciate the difference between the mk1 and mk2 electrical system when I went shopping for 'a B1200 engine'. The zuma seems to be based on the mk1 Bandit, meaning various connectors are different to the mk2. Based on a couple of threads on here, I understand it’s possible to plug the mk2 engine into the mk1 loom, by switching over the neutral switch, pulse gen+oil sensor assembly, and alternator. If I do this, I figure my Zuma CDI will be ticking over as normal without knowing any difference. An old thread about this transplant mentions someone running a B12 with the 750 Zuma CDI, and I also understand from a guy on facebook the 1200 Zuma engine can run happily with the 750 Zuma CDI, so I’m not expecting any major issues. I really want to avoid changing the loom as it then has a knock-on effect on clocks, switchgear, ignition switch etc. Q: Am I missing anything here? Will running the 750 timing have any serious detrimental effects on the 1200?
Fueling etc – So I’ll be running the B1200 engine with aftermarket can (I realise the blueflame can may not exactly have ‘race’ credentials) and K&N ovals. Q: Am I right in thinking this is a pretty standard off the shelf ‘stage 3 kit’ setup? What’s the advice out there on the best setup or jet kit for a Bandit mk2?
Crucially, if the consensus is it will need some proper dyno tuning work to run properly, am I best off skipping the DIY re-jet and just handing it over to a pro? What’s the cost for a proper dyno setup? I'm not looking for drag bike power here, just something useable and a bit fun.
Sure there’ll be other issues as I go along, will report back on progress Biggest Q of all: Would I save myself a lot of grief at this point if I just get a mk1 B1200 and CDI, plug into my existing loom, and save all the arsing about? I'm at the stage of carrying over the bits to the 1200 engine, so given another weekend I can probably get it connected up and see if the proposed combo works.
Cheers!
Matt
