After finishing the fuel tank and putting the bike together it was apparent that there was a significant issue with the running of the bike. It would not rev out cleanly, and would bog down when cracking the throttle. After lots of investigation and learning about fuel injection systems, I realised I needed to introduce a fuel return valve, that would return fuel back to the tank from the fuel rail once 3 bar had been reached. For this I butchered the original SV650 fuel pump and adapted that pressure relief valve for the purpose. I was confident that this would solve the issue… but sadly it didn’t! In the end after much head-scratching, beers, swapping out injectors from my wife’s SV and many other dead ends, I tried a new set of spark plugs, and the problem vanished. Now there’s a lesson in trying the simple things first.
Having got all the main bodywork parts together, and the bike running, it was time to give the bike it’s first road test. Without yet having all the parts done yet for carrying the rear lights and number plate, the only possibility was for an off-street test. For this we took the bike to Slovakia, and two days at the Slovakia Ring circuit.
So, the bodywork was finished and painted in preparation of the big outing to Slovakia…
