Yeah, no worries on the Specialist Components ecu... euro 4 I need up and running again though. Just not had time to look into it further.
So did I.! After racking up quite a few rides on it since, it’s definitely better but it still gets a bit snatchy & stalls occasionally on idle. Not as bad as before, but still not quite right.Deano, I thought you'd sorted your idle by fitting hose clips?
How did you block yours peebee?A strange thing happened when I blocked mine off, it stopped any oil going into my overflow bottle and zero oil in the airbox too even after hundreds of miles. ?. I still have to balance the twistgrip until it warms up to give it a tickover which doesnt take long, but if you have ever owned a 'Goldie' with a inch and a half GP carb with a sodding great bellmouth and no filter and NO tickover at all it's no great hardship , it's a genuine Britsh trait. When it's warm you can adjust to get a perfect tickover every time.
I would say no. But just a aluminum dowel cut down on a lathe to the dimensions that iwilson posted . Should be relatively straight forward for a machine shop to do ?
Look at this iwilson link :
As you seem to have the body off, how about just filling the whole passage with RTV silicone ? (It's also reversible).Thanks Tony. I see that he had a machine shop make the bung out of PU30 as a temporary solution, and it was fitted from the top of the throttle body where the IAC hose was connected.

Icrken had the throttle body tapped and used a bolt to compress a rubber plug in the hole.

There are a number of variations of throttle body in respect of hose connection points alongside the connection point for the IAC hose. Icrken's has an extra connection on the left, Iwilson's doesn't appear to have any extra connections whereas mine has two extra. I guess they had something in mind for these although I'm not aware of them being used.

I think if you use good quality silicone it should be ok. It's upstream of the injector nozzles and if you fill the cross passage and the air feed hole, it will be a sort of upside down T so shouldn't go anywhere. I'm afraid I'll have to defer on the MAP question as my bike doesn't have one either.Thanks, I was wondering about something like that. Just looking for advice based on what worked for others as I didn't want to risk anything that might end up inside the engine. I'm toying with buying one of the throttle bodies on eBay which could then be tapped/drilled etc.
Just out of interest, where does the MAP sensor connect to in order to get the pressure reading? I don't have a MAP sensor but I'm wondering if that's what the extra hose point(s) were intended for.
Norton Euro4 manual show the MAP sensor tube connecting to another "new" spigot in the left throttle body bore close to the injector .Thanks, I was wondering about something like that.

I got a piece of brass bar, made it the right diameter to fit into the aluminium casting and shaped the end to comletely block the passageway and left it long enough to come halfway up the tin tube. Then very carefully poured some araldite into the tin tube to hold the bar in place. The brass was such a good fit that no araldite got past into the passageway and it has never moved since.How did you block yours peebee?
