Bike throttle Bodies

[Billy_smith]

I;ve been given a set of keihn throttle bodies off a bike with the wiring a custom airbox the lot. i plan to make a ally manifold at work for them, but was wondering wether anyone on here used these and a megasquirt ignition? any info or advice off anyone on here would be much appreciated cheers

I cant see any probs using them im using gsxr 750 k4 bodys on mine with megasquirt n spark on my zetec and it goes very well.

thanks mate should work ok on me pinto then How much was the megasquirt mate and where sis you get it from?

[mr zefect]

I bought mine for 150 quid off some one on here years ago but it came as a kit and i had to solder all the componants myself and i had to modify it to run spark on edis it wasent that hard to do and theres lots of help on the internet. Have a look on ebay i think you can buy ready made with spark output already buit in with out the need to use edis unit just plugs straiaght into the coil pack for about 250 quid but dont hold me to that.

cheers m8. wot size diameter are your throttle bodies? mines are about 43mm. Do they sound gd?

I'm going to be using GSXR 600 throttle bodies on my XFlow. I think they are 38mm. I think the Megasquirt website gives some advice on what size of throttle body you should use. http://www.megamanual.com/index.html on the "injectors and fuel supply" page, about 3/4 of the way down.

 

I've been advised that Extra EFI is a good place to buy the Megasquirt in the UK. Not necessarily the cheapest, but good quality and service. http://www.extraefi.co.uk/ I've not bought my ECU yet, so don't have any personal experience with them. I've been too busy sorting out the practicalities of the sensors and fuel supply system.

cheers mate thanks 4 th advice

I think mine are 48mm and they taper down to 42mm at the bottom not sure as i havent messured them for years. As for fuel pipes sensors etc i striped a 1995 escort xr3i that i was given for nothing and took both flow and return fuel pipes and push conectors and took as much as the wiring and plugs for the injectors water temp + mat sensor so i dident have to muck around with dodgy terminals and it all goes to the megasquirt realy board that i would recomend geting as it makes thing a lot easier. As my tank had no return i welded one on to the tank and put a bigger flow pipe in it and i use a range rover fuel pump that has to be lower than the tank and xr3i filter. You will need to use tps sensor the one on the bike tbs will be fine and you will need to weld in a bung for o2 sensor on your manifold so you no how its fueling i use a wide band lc1 sensor and controller and dash gauge so i no whats going on while driving and tuning.

Any probs just pm me and i will try to help.
