Hi all,

I'm having problems with my SV and wondered if anyone had experience anything like it before or could offer some advice? It would be greatly appreciated!

I have a 2000 SV650S, 30,000 on the clock. Data tool system installed. No mods.

I started having troubles a few months back whilst riding, with the engine 'sputtering' or 'jumping'- It feels like I am pulling in the clutch and quickly releasing it again. It started off happening at higher speeds (50mph+) which was quite unnerving, but eventually started to happen at lower speeds.

This then progressed from frequent 'sputtering' to complete cutting out of the engine either whilst on the gas or off. So i would have to pull over and wait a few minutes a) for the ignition button to respond, and b) because it stank of petrol so can only assume it flooded in the process....

So over the past few months its been in and out of the garage and had: cleaned spark plugs, new spark plugs (ran well for a day and then back to the usual!), and most recently a new ignition barrel (the electrics were checked throughout the bike apparently and there was a fault in the ignition barrel- we knew there was an issue with it so thought this could be the cause).

I'd had it back a week since the ignition barrel had been changed and thought it had been cured, but a couple of days ago again at high speeds it started sputtering and backfiring as though it were miss-firing....and then at low speeds....and today has been an all time low! It must have cut out 4 times in the space of 100m. Each time i went to start it again initially the ignition switch wouldn't fire it (as though the immobilizer were still engaged) and then it would fire up with a backfire and die straight away.

The guy I take it too thinks the immobilizer magnets (?) could be worn and causing it to cut out, so I think if I take it back to him that will be the next thing he takes a look at/tries to remove. I've been wanting to sell the bike so I can get another one but feel I can't pass it on to someone in the current state unless I sell it for pennies.

Any thoughts?

Thanks for your time!
