Hi. Can anyone help/suggest what's wronge, i will be very gratefull. I class myself asa noobie, but have been riding a while.

While riding my CBR600F 1989 at about 70mph (going thru a speed camera - bloody M25!) my engine cut out. I dropped it down a gear and bump started while going along. It happened again,with a massive backfire, and it felt as if my throttle cable wasn't connected, but it definitlyis, because all of a sudden the engine would pick up. It continued to cut out, and start again from me dropping down a gear and releasing the clutch.

It seemed better if i kept the revs high (over 7000rpm), and with the choke completely on. Only cutting out when the revs dropped (bloody speed camera's, bloody M25, bloody lorries, bloddy M4, bloody bus lane on a motorway?!?!?!?!?)

Eventually it completely died. But i did manage to get it going by bump starting it, with a little help from a friend.

Right. A few things that i have done recently that may have led to this problem.........

As per many previous blogs, my battery hasn't been charging when riding so i've been having trouble starting my bike (r and r, or other prob's), and i haven't sorted it out yet. I've just been bump starting it, and leaving it on the top of a hill whenever i stop. But i dont think this is causing the problem? Am i wrong?

Also.

After getting some crap advice from a friend (he said i can use any coolant/antifreeze?!?), i topped up my coolant, without checking whether it's the right stuff. Can someone tell me what the right coolant is to use, and whether this might have caused the problem i explained above.

Any comments will be much appreciated, and anyone who takes the ****, i dont mind so long as you make me laugh.

The motor issue sounds like you need to replace your R/R and see what that will do, I recall my old 92 EX500 did this when the charging system went.

for coolant, if it says its safe for use in aluminum motors, you're good to go.

 

I think most coolants will work, as long as there not 100% water; since the block is aluminum, it will oxidize. As for the stalling, it can be the R/R, the bike will die at random times, including while you are riding it. Then sometimes it starts back up, sometimes it wont.

 

rrasco and hurricane rider, thanks alot for your words, much appreciated.

i realy hope it is just the rnr, i thought it might have been something else major. just spent £400 squid getting it thru the mot so low on funds.

thanks again, i'll let you know how i get on once i've replaced the r n r

 

Make sure that nothing is clogged. IE: The Air filter, Fuel filter... You could also be running lean too. Make sure your carbs are adjusted right.

 

Thanks bojak.

 

To anyone that's interested.

My new parts arrived - r and r and a new stator. while removing parts i realised that a hidden fuse had gone. i replaced th fuse and all is good. the battery is charging after every ride, and no other problems.

i now have a brand new r n r and stator for sale if anyone wants them. email me tigseyjnr@hotmail.com

thanks for giving a ****. Tigs

 

You have email waiting for you. my luck is just awful enough that I"ll probably burn up a regulator or stator somwhere out on the road.
