Dt rich

Hey no I haven't changed the pick up as its fairly new any way I have wiggled all the wires and put a new ignition on I'm pretty sure it's electrical problem aswell ill try another pick up when te rain goes away. I have checked wireing it is in a bit if a mess but no wires broke or pinched except a brown one that goes in To the headlight not to clued up with elecs tho but I see that broken before It started this problem. And I did not think the power valve would corse that much trouble as only moving about a mil or 2 thanks for clearing that up To put a feeling to it feels like your running with the choke on (which I'm not)

Nope no oil or anything else leaking its all lined up properly aswell ill try get it on a video later and post it

It is pinned open but pushes out I mean literally pushes out of the side of the barrel only a tiny bit but only does it when it is bogging out ad I want to set it up but I need the little plastic pulley that goes on the end of the power valve then I can do it got servo cover cables and all wires are on the bike

No worrys if you get any luck let me know please same as I will let you know

Hey glad to see I'm not te only one with this problem And I've read that post about ten times now don't really help me to much thanks tho It might be going to a shop tomoro if I can get a deal on some cheaper labour if it does ill post what the problem was if they find it (don't like paying labour but run out of things to check) I have tried a different magneto as got 2 spare bottom ends and still done same thing so don't waste your money just yet as I still think its some thing simple

Could the power valve make the bike do what it's doing? As the power valve pushes out of the barrel only by couple of mil but were I haven't got the servo it should not be moving at all?????

Was not the jet tried a 210 and done exactly same thing :s

Okay I will try that today was running fine with 240 before this started and I knew from the smell the heat to touch and temp gage nearly on red usay sits just off of cold. I see what your saying about bogging motor as took petrol tank off yesterday started bike and it was ticking over for like ten minutes with no petrol tank has never done it for that long before Thank you for your help ill keep you posted and have a read on your spark plug and temp post

Standard is 210 and runs rather hot so put a 240 in it which runs lovely spark plug a nice brown colour Think in going to have to pay some labour as I'm not getting any where I'm tinkering on it all day every day

Still stumped new carb new coil new spark plug cap new reeds new ignition new plug checked exhaust Any one in Kent fancy a bacon sarnie and brew all day haha

Yer I no I am in process of doing the power valve servo just need the pulley got everything else and I live on long straight roads so usually higher up in the revs so it dont bother me no bottom end and yer I have had a look at the expansion chamber looked pretty clean but did not look in silencer could that course this problem it's got a full dep sytem on it Thanks so much for your replys

Yep had carb off and been soaked in carb cleaner and sprayed compressed air through all jets and passages air filter is clean no air leaks and I have played about with air screw no luck there have gone all the way to 2 and half turns out then back in to 1 and half turns were it runs its best I'm completely stumped now when it misses the power valve pushes out a little bit if that makes sense don't no if it is meant to to that (no servo fitted just pinned open) also tried another carb did not make a difference That's why I think it is electrical :s On another note if any ones got the pulley for the power valve for sale pm me please

Nope the power valve was only part of the problem any one else got any ideas I cleaned the tank and Petcock all looks to be working fine

I think I have found the problem thepower valve had moved and was bouncing in and out just a bit of fine tuning

Thanks for your reply I will have a look at that today it is so strange here is a link not my video but exact same problem http://m.youtube.com/watch?v=FRy6i2PnUkk
