Thank a lot for your advices

Hi I believe my rear coil is breaking down when hot, I have seen coils off an st2 and an st4 cheap on ebay will these run my 907 ok, thanks all re Alistair

Just an up date. I have started pulling the bike apart and found what appeared to be an oil leak. the oil was black and very light. on closer inspection it looks like it has come from the exhaust manifold on the rear cylinder I removed both plugs and the rear cylinder plug looked a bit oily compared...

Cheers for the advice I did the tank filter and hoses. But funny you say plug leads only a guy at my local gym said it sounds like a plug gone down. So maybe best to look at leads and coils first .

Hi all finally got the bike running this year after 12 years lay up worked on it all last year tank hoses. Injectors. Plugs. It runs very well when cold but once warm it is very stuttery when held at low throttle between 1000 to 4000rpm it also stalls regularly when dropping off the throttle. The bi...

Got It sorted . It was the coolant sensor . Starts first touch of the button. Cheers all. Also the coolant that I lost while fixing it apheared to be a green colour. I haven't seen this before and only have red or blue can I use one of these or is it important to track down some green. Cheers again ...

Cheers for all the help . I was working on it last night and found it kicks up pretty fast if I hold the throttle full open when cranking but stalls just after starting. repeat this and she then fires up and runs fine . I will check what's been suggested by the posts on here . Once again thanks all ...

Hi all, I have been trying to find whats causing my 907 to have to crank for ages to get it to start when cold. I first thought the regulator was at fault but on bypassing the injectors found it held 3bar for hours, so hooking the injectors back into the line I found a steady drop to 2bar, right so ...

Just removing my injectors from my bike its a bit dark in the shed and cant seem to see away of getting the rubber fittings on the air box (that connect to the throttle bodies) past the injector rail, do you have to remove the rail first before getting the airbox past or is there an easier way that ...

Yes sparks seems ok I have hooked up a gauge just off the end of a pipe that exits the fuel tank delivery I flicked the key till the pump reached 3 bar then turnned off the pressure it held for hours. I then took the pipe off the exit side of the injector rail and hooked it up so the fuel bypassed t...

Cheers for the reply what do you you think my best course of action should be to trace the problem I thought about blocking fuel line somehow before it reaches injectors to see if pressure is held by pump just a fast flick of the key to get near 3bar and see if it holds. What do you think. Thanks ag...

Hi all I have been having lots of problems recomisioning my 907ie it had been dry stored for over 10 years until last year, I got it running last year after a good clean through and fresh fuel and it was spot on started first touch and ran well it was ok for a month or so. I then couldnt get it to s...

Thanks for all info I haven't had time to do anything with the bike yet, but I also found that the fpr off a sierra rs cosworth from the 1980s looks a fit and there are aftermarket adjustable pressure ones available so i might investigate further, cheers all

Thanks for the replies just a question there is a small pipe routed from the regulator to the the intake what is its purpose, only aftermarket regulators I have seen haven't got this outlet and have only a supply and return. Thanks again re Alistair

Hi all where would the best place be to get hold of a fuel pressure regulator for a 1992 907ie in the UK
Cheers re Alistair
