Seems to have good compression and I done crank case seals last week I thought might be piston related so I just placed an order for a 70cc big bore kit

Never had a Bonneville I had a 59 tiger 650 twin until 1981 and a BSA a65 650 twin but the 1st bike I had was an FS1E when I was i6 and a Suzuki gt185 when I was 17 lol

yet oldie59, on 6 days rest now (work shifts) so will be looking again, Trade wise I'm a HGV mechanic, Give me a 4 stoke derv engine and ill do it blind folded, only 2 stokes i've done was when i was in my teens, Going to show my age now 2 stokes had points and the piston was the only valve, and the carb bolted to the barrel, lol no reed vavles and no CDI's lol

Yes the coke works fine, fuel not getting to the cly has been the problem all along, that's why I have done all the seals, gaskets, Reed valves and new carb,

This might help you MOT Manual free the link is https://www.gov.uk/government/uploads/s ... es-1-2.pdf Section 2 - Page 2 Method of inspection - Item D Reason for rejection - Item D

I think your fine that it will be classed as a small motorcycle if it has no restriction and not a moped, so the MOT regs are different from that of a moped, like lighting, tyre treads an so on, best check

You might think I'm mad but its a Chinese bike I have a Chinese 400 Skygo (copy of a Yamaha virago) and it will not start if the Side Stand is down, Turns over but will not start until I flick it up - bit of a pain in the butt as its not got a main stand so working on it was a pain until I by-passed it

Its got a new automatic electronic choke

the bike has a auto choke on it both on new carb and the old one. Plug gap is to the gilera specs

I have a 2003 Gilera DNA 50 that i just cant seem to get running, I have a strong good spark at the plug and have tried a few thing on it but still no good, Air filter is clear, Fuel pump and fuel Tap are fine , exhaust system if fine, The timing you just cant get wrong (unless you forget to put the key in when you fit the flywheel) and the fuel is only 5 days old I have also just just fitted, the parts listed in the hope to sort it out, 1, New spark plug 2, New 17.5mm carb 3, New reed valve 4, New Inlet manifold 5, New Base, and cly head gaskets, 6, New crank case gasket 7, New Crankshaft seals, and when I say new I mean new not second hand, all the above i have tried with a gravity feed fuel tank, and with all the vacuum pipes blanked off just in case of leaks and i have tried it with and without the exhaust on, I'm now out of Ideas, The only thing I have NOT tried yet is a piston, rings, barrel and head as I have compression on it, If I hold my hand over the intake before I changed the parts I could get it to fire but that's about it and its the same with the new parts Thanks Andy
