Mark, there was a little dirt in the bottom of the tank but not much to be honest, the filter system looks very good on the 4rt so doubt much has got through at all

Right, all back together last night and took the old gal out for a spin up the road at lunch time today, probably ran her for about 40 mins in total. Ran perfectly, no signs of a splutter or cough at all? I checked pretty much all the connectors on the bike and cleaned then, although to be honest they all looked like brand new inside, the only other thing I have done is by pass the bank sensor. I'd already put a new plug in after the Vic so did'nt put another in. Fan seemed to work fine so I hope the problem is the sensor (which isnt needed anyway). Not 100% convinced as the bike did run perfectly for about an hour and a half on Sunday after I had whipped the fuel pump out and cleaned it, but hopes are still high she's a goer.

Probably take it out again Saturday morning for a longer spin and if ok will enter the trial as is, Gizza will have his spare tank on hand incase the stalling rears its ugly head again.

I found that I needed to ride 30 mins or so at low speed - Ie up a long brook section and then it would start to miss when opening it up to climb out the bank or ride off to next sections. Maybe low fuel use low air speed passed engine creates worse case senario.

I could also get it to play up by putting it on tickover and covering tank up with a blanket. Once it starts it is quiet repeatable.

Hope its not the pump tho and good luck for the weekend.

Thanks Jim,

Might try some low speed stuff at the quarry Saturday then and see what happens, running on the road seemed ok though

Whilst cleaning the electrics I did the suspension linkages as well, I've had the H&D dog bone in Gerts for a few months now and it it looked the same the day it went in, still grease in there and moving perfectly

Something else I noticed on Sunday was when I took the fuel line off there wasnt a washer under the bolt? is this correct? looks like maybe there should be one? not leaking though

Ok, did the trial at the Yennards today, kept my tank and pump on to see what happens and if removing the bank sensor was the problem. Bike ran ok for first three laps, although had a couple of fluffs, started playing up after that so swapped my tank/pump over for Gizza's. Rode to the next section and noticed the bike was'nt quite right and whilst in the queue heard the fan touching the radiator again? Fan eventually packed up soon after so now have a good idea its a bust fan causing the problem not the pump. Will order a new fan tomorrow

Got new fan and thermo from Munch today, (thanks mate) would have come yesterday but our posty was ill so the temp took it back to the depot going to fit tonight and give the bugger a good run tomorrow afternoon. My spanners have never seen so much action since the Caby, all dust and cobwebs have been worn off, lets hope I will be tucking them away again come weekend.

Bloody hell bet he was shocked

All back together today, new fan and Thermo fitted, old fan was definatley ****ed, new one span alot different and easily. Ran her for about 30 mins with no probs, but it usually takes 1-3 hours before something coughs, fingers crossed for Sunday

Fingers crossed for you as I've been through the intermittent problem scenario

Thanks Jimmy, will let you know how she goes

Long story made short, If you have F---'ed the fan with a stick, then I don't even want to know how "she" goes!

Twisted b----ard!

Berko Trial today, was going to use my tank but decided to use Gizzas so I could at least finish without swapping over if there was a problem. Bike ran all day but was trying to stall quite often especially whilst in a queue? tickover quite high, runs nice and smooth then dies abit and picks up again? didnt actually stall but did this a couple of times in sections on slow no throttle turns. Will try my tank at Yennards next Sunday and see if its the same thing, running out of ideas now as Gizzas fuel pump is a minter so can't be that

Is it like the kill button being pressed for a second and then released.? Only on tickover or minimum revs.
