fuel injection

[pgnz]

yep they're 36mm and a couple of mm's different in spacing but they plonk straight into the xs11 manifolds,

(to be fussier lightly skim a mm or so off the inner side of manifolds 1 and 4 with a dremel or suchlike- that's right inner on 1 and left inner on 4)

got to also slot the airbox mount holes to move the airbox forward a few more mm's

(forget about using ditzy pod filters on cv carbs) also got to fit a matching throttle cable connection, a choke cable connection and go up on jet(keihin) sizes..  for an XS11 around 38 on pilot jet and around 130 on main jet..

to run vac advance, plug to a manifold thru a restricted(0.5mm) hose,  means it'll tick over at idle sweetly at about 15-20 deg advanced versus stock EPA idle advance of around 5 deg..  btw the zrx carbs are snappier and smoother and more responsive than the BS34's you notice a difference straight away

so will the carbs of a zrx1100 fit? if so then it might be cheaper for me to look out for a second hand set thats ok.

these fit ,  a bit of tweaking and they run primo on an xs11

..though those ones look too crappy for that price..

i haven't looked at the FJ or XJR system. the GSXR throttle body is what most people are using. my main reason for wanting to go injected is that all 4 carby are flooding bad, so caby kits x4 and 3 of the floats were full of fuel, the carbs still leak badly even after i had fixed the floats and set the height, then all 4 carby diaphragms have holes. when you add up the cost to rebuild the carbys its a lot of $. on the up side the body's are in good condition. i would like to stick with carbs its just means the bike is going to take a little longer to get on the road.

The thought has crossed my mind to look at the FJ or XJR EFI systems??
Any thoughts??

Jazz, here's a quote from a thread on the uk site from Shappers, owner of the bike in the third link down in Christians post plus the video:

I just don't have enough time to spend on it and to sort out the fuel injection system I fitted. I always need to relearn it all and reprogram it just for a simple ride around the block. I don't even own a laptop with the required COM port anymore!

Well I made a watershed decision this week to just take it all off and to fit a set of carbs. That way when I get a spare hour or two I can just fire it up and go for a ride instead of struggling with my notes and wondering which fuel map is going to get me running.

and a link to this thread - CLICK

He has abandoned the megasquirt system and reverted back to a set of ZRX1200 carbs due to the fact that his bike sits for extended periods (he lives in Finland, hence a very limited riding season), so if you're looking at using your bike sparingly, I'd say have a good long think about your options, plus maybe send Shappers an email for his opinion, as he's been there, done that.

thanks for the links
it was good to see a parts list broken down with the $ too.

it might be fun to play with 1 day ....when i win tatts and leave work.

Hey Jazz,

Have a read of this blog on XS1100 EFI (from the .com yank site)

the threads I've seen on xs1100 fuel injection have all been geeky long-winded waste-of-space, deadly-boring affairs about megasquirts/programming/diagnostics/worm charts/textbooks/over-priced parts/constant troubleshooting troubleshooting/always something wrong/playing up/re-programming/more diagnostics/ more twiddling/ more flowcharts & digits/running like crap blah blah/if running at all... mediocre results etc...they all fade to oblivion.....  throw some modern carbs on instead...

[Jazz]

just putting it out there, has any one played with putting fuel injection on there bikes. i have found some people on the net that have used the GSXR600 throttle body's and an after market fuel computer to control it.
any thought on doing this?
