Pmsl no worries bud just this is doing my nut in
There is morr infprmation in my project thread

I even removed the air filter placed my hand over air intake and she dies so deffo dont think its a air leak could it be sonething broken in the engine so the piston is running freely with no resitance
-
Its a sliider carb and doesnt have a diaphram i have notice my bike will roll in gear and rear wheel rolls easy
-
Clearance has been checked and all fine no air leaks i can find even removed throttle cable and still revs its nut off its driving me crazy

is there ckearance on the exhaust valve tappet when it's not on cam?
How would i go about checking for clearance ?

Didnt remove the manifold, hasnt been fuel starved, fuel flow is good and yea the fuel cap is venting fine its confusing the shit out of me why its climbing maybe its trying to idle very high possibly thats y it keeps climbing
My gasket on the exhaust needs doing but wouldnt have thought that could be a cause

Time to throw a spanner in the work
The ped i was using for work has started to develop issues (chinnese) so ive had to stop using it and pass her on before she isnt worth a penny so im forced to put the sr back on the road unfinished i wish i had another option but needs must
Engine is back in and all electric are wired up but i this the netural sensor has gone so i cant test fire the engine

not sure mate, with imports you are subject to customs charge and if not pre paid, post office will charge £8 for collecting the money
Just checked online I would need to pay 20% vat and 3.7% custom charge so probably not a good idea as if probably need a wheel from across the pond too

Cheers drewpy
Can get one off a 250 for same price do you know if it would fit I've done some research and looks like most of there parts are pretty much interchangeable but I'm not 100% sure on that and dont wanna pay postage from the States on sumit That dont fit

Looks to me like a welded plate, so for what it's worth cut it off and take it to your local welder and get him to replace the plate with some nice shiny steel. Better still leave it on and get him to remove it and then he can see what needs to be replaced, yes by the way almost certainly structural.
I can replace it for £30 do you think it would be cheaper then the repair ?
Or I might get a 250 swing arm then I could fit a larger rear wheel on

Evening guys
I've run into a little road block after starting work on the rear swing arm I've found some bad corrosion on the underside
I've was wondering if anyone would know if I could cut away the whole bottom panel or is it structurally integral and cheaper to replace then have repaired?
