Yes , that’s the one, the overflow drain is blocked solid just above the nipple which means water sits in that cavity after rain or washing the bike and runs into the fuel tank the moment you open the lid. I am unsure whether the nipple screws out because mine is offering quite a bit of resistance. I’ve tried soaking with wd40 , poking snipper cord, compressed air to clear the blockage with no success. I don’t want to damage the tank if the nipples aren’t removable.

Hi Docc I’m referring to the fitting / nipple on the underside of the tank where any fluid around the outside of the filler neck drains. There are 2 fittings that have 6mm hose attached to drain fluids and allow the tank to breathe.

Hi In the way of an update. After I had exhausted my options/ limited knowledge I took my bike to an experienced MG mechanic. I got the bike back running nicely albeit a slight hiccup around 3000 rpm. He used the original tps and replaced the slightly perished inlet rubbers but didn’t really have any one thing he had found wrong. Fast forward 6 months and a couple of thousand trouble free kms , and one day the exact same on again off again misfiring is back. This time I noticed a couple of things I’d dismissed first time around. I’d just refuelled and noticed fluid run into the tank when I popped the lid whilst on the side stand. The drain under the lid is blocked and when I washed the bike water pooled in that space under the lid. I have drained and flushed the fuel system and have the bike running properly again but I am having trouble clearing the drain. The fitting on the bottom of the tank ( I am guessing it’s a one way check vale ) is very tight and I don’t want to go too hard and damage the tank. Does anyone have experience / advice removing this part? any advice is much appreciated Regards Tony

Thanks again for the interest and responses gents. I’ll check that out MartyNZ , thanks for the info and I’ll keep you posted. Tony

I suspect you’re right Docc , it was sourced off eBay. It was cheap and sounded like it fit the bill. 😒

Yes @gstallons , this is an old cat diagnostic lead not ideal but serviceable. With the tps in my hand but connected the minimum reading is 204 mv . With very slight pressure using a screwdriver in the slot it will get down to around 150 mv.

Hi , Thanks for all of the responses and information provided. I’m using a modified caterpillar test lead (pictured )which is not ideal and may have contributed to my confusion. After testing the old TPS using the info above it is definitely faulty and doesn’t have the range as described. The new TPS has the full range to 5v but the lowest reading is around 200 mv whilst mounted. ( ie the slotted holes run out of adjustment. I can get 157 mv with very slight pressure once the screws are removed. ) I might try to elongate the screw holes slightly to achieve 157 mv. I will have more time over the weekend to work on the bike

Thanks for your responses. I had the idle screw backed out and the link arm disconnected. RH throttle completely closed , key on and engine kill switch on . I am not getting anything above 2 to 4 mv . This is a new tps which is getting the same readings as the original. 🤔 Appreciate any further thoughts.

Hello Hoping to get some ideas / expert knowledge from the v11 brains trust. MY 2000 RM started missing , running very roughly and blowing excessive black smoke ( both cylinders ) recently. I nursed it home and I’m trying to sort it out as the local shops aren’t very keen on working on an old guzzi. After changing the plugs and fuel filter I tested the air temp and engine temp sensors which were fine. I decided I’d work my way through the “decent tune up” which is excellent by the way. My problem is when setting the tps I am only getting between 2 and 4 mv at my multi meter. I have tried 2 decent multimeters with the same result. Has anybody had this experience ? I thought I would ask the question in case I am missing something simple. Any feedback would be much appreciated. Regards Tony

Thanks for that , I ll be looking into it in the new year. Much appreciated. 🙂

Hi Can anyone identify the pipes on the Scura ? I would like to fit something similar to my RM . Are they original or after market ? thanks in advance

Thanks for that footloose , just the KTM and the v11 , the others were bikes that caught my eye around town. A lot of serious knowledge in this group, I look forward to checking in from time to time !

Thanks for the heads up boys , however apparently I don't have the correct device so my partner has suggested this method. https://flic.kr/p/2iQKDaA https://flic.kr/p/2iQNxPn I hope this works .

Correction build #227 not 221. Still working on a photo.

Hi all, number 221 resides in Mildura Australia , recently purchased from Perth . I can't seem to attach a photo atm. It's saying my photo is too many MBs . Any advice would be appreciated.🙂
