jimbob43 Posted July 4, 2019 Posted July 4, 2019 Is a 750 dot head a straight fit onto a 1200 bandit lump, getting a frame built so got plenty time to do an engine, dont want mega hp, but was looking at fast road cams and fcr,s, for the moment Quote
Swiss Toni Posted July 4, 2019 Posted July 4, 2019 I think FBOAB was getting 150BHP with just the head & cams on B12. He'll be along shortly to confirm ... or not! Quote
fatblokeonbandit Posted July 4, 2019 Posted July 4, 2019 Not quite Tony, I have done a coupl in the past and the gsxr DOT head with cams gave 130 ish with pod filters and decent exhaust, after dyno setting up.. Excellent bolt on hp , most people say now you must dial in the dams, I did mine ages ago and didn't really know about that do I bolted it all together and rode it, they rev much quicker but loose some midrange, but fun fun fun,, good of luck finding the head and cams cheap nowadays though, Quote
wraith Posted July 4, 2019 Posted July 4, 2019 Just did it on my gsx1157et project engine, bolted strait on no messing. I haven't dialled in my cams (I'm using gsx1100f cams) just used the standard b12 cam sprockets, all turns over ok will see what it's like when running. 1 Quote
Foz Posted July 4, 2019 Posted July 4, 2019 Dot head on a bandit does give a few clearance issues due to the carb angle. I did read that Mr upperton said the dot head doesn’t flow anymore than the bandit head so you could keep the bandit head and raise the compression to get the same result in theory Quote

jimbob43 Posted July 4, 2019 Author Posted July 4, 2019 Given the choice what cams would i use with the dot head, just fast road cams nothing over the top, 750 1100 or 12,s Quote
wraith Posted July 4, 2019 Posted July 4, 2019 All depends on what you want? Top end bhp go for gsxr750j/k. Any of the gsxr750/1100 will give you good top end bhp over b12 cams. If you want just bottom end torque keep the b12 BUT these will not give you a good bhp. Or you could go for gsx1100f power screen cams that are a more all rounder cam.I This is a very basic over look at cams don't forget if you dial in your cams that helps but as to what settings to go for someone who knows more then me will have to answer that one. Myself I'm using the gsx1100f cams as I like the way they work in my 1127 motor the power is there from the start and I don't need to get up in the revs to get the power. Quote
fatblokeonbandit Posted July 5, 2019 Posted July 5, 2019 The whole point for me of doing this convention was the cost, it was over ten years ago, I got a complete 750j motor for £35!! The gearbox was shot so not worth fixing... I bolted the head and cams on and it went like fek. Today you have to pay several hundred pounds for a good DOT head and the correct cams, so it could be cheaper to get some reground cams and a head job... Quote

I,ve been lucky, i,ve been given a complete dot head engine, so i dont mind paying for some cams 1 Quote
wraith Posted July 5, 2019 Posted July 5, 2019 There was/is a dot head with cams on eblag starting bid £150 don't know if it still up for sale or if its ended. Quote

wraith Posted July 5, 2019 Posted July 5, 2019 (edited) Gsxr750k but it's ended and it was £175 + £15 post but looks like it had no bids so it may get relisted. This head has nothing to do with me just passing it on Edited July 5, 2019 by wraith Quote
