agree looks like silver rims ,head and red mudguards and red side case make it a 350 ,peg mounts have been modified so possibly just had frame painted

maybe try putting one of them small flexible cameras inside to have a look , like you say its had umpteen differnt caps so must be something happening inside the tank , would be interesting to see how it went running only on a front mounted tank like the hebo one which you can see through

i wouldnt use plugs with a resistor and try a strobe light on it with plug in cap on to detetmin if still sparking under compression

adding a drain to your airbox would be helpfull

could you get it welded at an engineers or try getting a new lower from lampkins and swop it over

BOYSENS WORK BETTER THAN ORIGINAL ,OR MAYBE TRY RESTRICTING AIR INTO AIR BOX AS COPE SUGGESTED PROBABLY OVER CARBED

boysens maybe ?

i would also try adjusting the timing it can make a big difference , i take it the air intake is all standard

use a car battery on the floor does not need to be connected to the bike ,and connect to ht lead

TRY A STROBE LIGHT ON HT LEAD WITH PLUG IN IF OK TRY A COMPRESSION TEST

especially in sunderland

looks like the hole is worn or damaged , you could get a small 10mm head size nut found on most vehicles that have a washer part of the nut , turn upside down sit in hole and weld it in ,or weld nut to small strip of steel sit in hole and rivet plate to frame

mine has started doing the same thing comes on then stays on its not normal , i am suspecting the thermostat is faulty but not yet looked

if the rear shock is damping ie not like a pogo stick its probably ok if your on the heavy side you could tension the spring up

the bolt threads into a steel threaded insert nut , if you can get hold of a gas welding torch you can have a small flame to heat this nut up also a socket type allen socket used on a hand impact wrench would work good but as above fit socket and bray it in to also get some shock through the bolt before attempting undoing

from what i gather it must be the steel lever type which as you say you lift it and the plunger goes down for on , this should have an effect so it is either choke on all time or off all time ,, also the mixture screw should cause a difference when adjusted , so a carb overhaul is due , but check air filter first

around 1500 as they are far and few between there aint many parts about not sure if one on ebay recently

more than likely piston slap

think my uncle walter used to work for them , they offer good value for money

You now need to bleed it properly then restart put into 1st whilst pushing it forwards go up through gears with clutch in rear brake on and off untill it clears or rock back n forth in 5th gear engine off clutch in untill it comes free

You might after drain the oil and put the correct amount back in . You might find a differnt filter will fit if you give a trials supplier dimensions very good bike but bit heavy . Also try steve goode in wales

you have to of disturbed something or put something together wrong poss needle not in correctly ,does throttle feel ok ,, if so check spark

Price would be ok if as described i would get in touch as its a dealer and hes described as mint at the least you could do with a casing from them

WHAT WAS THE ITEM NUMBER

what year is it , i think 06 on they had chrome forks as did the 200 as a pose to black , i think the older techno do feel more responsive than the equivalent rev3 but check if its got a flywheel weight ,, maybe ring lampkins with frame number
