In need of some help totally stumped. I have a 07ds650x all stock except uni airfilter. I was riding for a good three hours then it just stopped wouldn't start backup towed it home. Took it to dealer multiple times thinking it was carberator they agreed messed with it . Had it running picked it up took it out ran for around an hour or so then just died again took it back they said carborator was bad. So i bought new one they put it on also adjusted valves rode it around said it was perfect picked it up rode again an an hour or so it died again seems to me like its dieing when it gets hot because after it sits for awhile it will start back up an run for alittle time then do it again.totally lost what should i replace or look at any suggestions would be greatly appreciated thanks. By the way first post if you can't tell

i had put a big gun cdi on my 04baja x. it ran n then all of a sudden shut down. then ran when it wanted. then shut totally down. then ran on off on off. like burnout---nosedive---burnout---nosedive... then I replaced it with a dynatek.

 

Thanks for idea. I have a stock cdi now can anybody tell me what a good after market cdi would be? I plan on leaving ds mostly stock maybe few small things. Any help would be great. Thanks in advance.

 

A BigGun CDI is your best bet. You won't need the Vortex if you plan on staying mainly stock but the BG will give you a little more performance.

Check your grounds. May need to strip some of the paint where all of the wires gather. Check your voltage. 12 while sitting. No lower than 9 while starting. 14.5 while running. The DS likes a fully charged battery. Gremlins otherwise.

Do the OMR stock carb mods.

That vent line that wraps around your fuel tank and gets pinched or kinked on ocassion is where I would start. Causes the exact symptoms you describe. Regulator/rectifier, grounds, battery strength, are where Ilook next.

 

Thanks aceisback... are there different different big gun cdi s?? If so which model is a good one?? Thanks

 

There are two for the DS. Make sure you get the one without the pig tail. Specs are the same, just a difference in the connection. All over freebay for around $130 shipped.
