Hi. I have looked up various posts on engine swaps do have the basics that most are interchangeable but require a varying degree of other parts / work to complete
My f4 750 track bike is now actually going well. I posted about a year ago with handling issues and fuelling.
I now have Maxton front and rear and one of X bikes ECUs. The handling is still a little compromised but it’s good enough to track day and the odd race.
The power is now though a little low (circa 110bhp).
I’d like a 1000 but I’ve put £ thousands into this bike and do not want another bike in the garage as I dont have space.
I have a line on a 312 motor which send like the best one but also seems to have more variation than the generation 1 1000s.
As I have the motec eco and it’s not a road bike I think Chris will be able to getting the fuelling to work etc with my loom, maybe cutting and shutting a few connections etc.
I see the throttle bodies are larger on the 312, will my 750 bodies bolt on accepting that I’ll lose a bit of power (which I don’t mind) or do I need the 312 bodies and if so will they then fit my air box etc?
I am assuming I’ll need a new exhaust but is that correct? I’ve a standard 750 header with Sil silencers at present. I imagine I’d get better gains a with a 1000 race header but if I can start out with my exhaust and upgrade later that would spread the cost
I have a Febur race rad on mine. I’d like to swap that over as it was expensive!
I have a mechanical slipper clutch fitted in mine (really was essential for track riding), I would like to swap that in or will the motec Ecu co trail the 312’s bleed system?
Chris at X Bike’s has my bike at the minute and would do the swap if I went ahead with it. I am sure he could make it work what ever but I’d like to know in advance what I’m letting myself in for and also which motor would be the best donor when balancing what needs to be done vs performance.
I am not keen on the 910 option as the power gains are not significant enough to justify the cost.
My 750 motor is fine so this is a luxury not a need, but I feel I do ‘need’ the go of a 1000 ?
I have asked Chris these questions as well and I’m sure he may have them all but I thought I’d ask the forum also as it seems you have done it all at some point!
Thanks
Pat.
