A little Help Please.

Bike was running ok pulling like a train then the other day first time out for a while every now and again the revs suddenly dropped off when at low speed and would stall if I did not blip it quick. Once running out on the sweepers and revving hard she felt fine never missed a beat, but as soon as I was at town speed under 3000 rpm she would try to stall. I have sorted the idle trim and got it to just about within the correct area, so I then stripped off the tank and air box to maybe put normal plugs back in as changed to iridium a while back to see if that was the problem, or maybe renew then coils... when I noticed this in the pictures below. Could this be my problem a hole in the pipe that comes off the throttle body and goes to the idle air control valve ? Would this contribute to the motor wanting to stall at lower revs ? I will replace these corrugated pipes first before I start buying new coils etc......All thoughts gratefully received, thanks.

You have put your finger right on the problem: Perished IACV (Idle Air Control Valve) hoses that are letting in air. It's a pretty common fault.



Heatshrink is a good fix. Here are a couple of other temporary fixes:

Absolutely the problem!
OEM hoses are expensive - pick up some vac hose at your local motor factors (auto parts store to US types!) - should be able to get it by the foot (get 3' at least)

You will want to revert back to your original mappings after replaced - all you've done is put more fuel in to match your leaking air volume so it will be rich when you correct the air issue.

Thanks both Deano and DEcosse, for you quick response. I will renew these, with some more substantial pipework. Hopefully then after adjusting back the idle trim as you say DEcosse, we should be running fine fingers crossed.

NJC955, While the cost and performance value of the iridium spark plugs have been debated, they're not going to cause any problems. A coil failure most often will throw a code and illuminate the MIL.

Depending on your mileage this maybe an opportunity to measure and record the valve/cam clearances. Reinstalling the cam cover is the worst aspect of the procedure.

Brad

PS If this is the first time you'll reinstall the airbox, make sure the throttle body clamps are quite loose to properly seat onto the throttle bodies.

Hi Brad, Yes had the air box off earlier this year to fit the iridium plugs and to fix number 1 coil clip, so I remember what a bugger it is to squeeze the airbox back into place. With regard to the mileage mine has only done 6900 miles in its life, I just do not get the time to ride or even work on her, infact this year I have covered 700 miles, bit different to 25 - 30 years ago when I was a motorcycle courier plus only had bikes as transport (The good old days) so with such low total mileage I would imagine the valve/cam clearances should be ok ! At what mileage should they be due a good check and adjustment ? However for future reference how does the cam cover seal, is it with a gasket or a re-usable rubber seal (which I would most likely replace anyway as the bike is now 12 years old).

NJC, The cam cover has a reuseable seal. The seal isn't difficult in itself, just the cam cover passing through the coolant hose forest to put into position. The cam/valve clearance check is recommended every 12K miles.

First major service 12,000 miles / 20, 000 Kms. And yes, if removed carefully, the gasket is reusable. Silicone needs be applied at the following spots:

All sorted now, fresh hoses in place went out for test ride, and now running lovely.......except now like DEcosse stated I will now have to re-adjust the idle trim as she is now again not happy on warm restarts.
