Hi, I'm in the process of getting a '99 600F4. Everything looks good (to my novice eyes), Low miles-5900. The present owner said it has sat for a while in the garage & gas was old. I test road it & the thing idles fine it's just that when you give it a little throttle it dies. Only way to make it go was to get it to about 4000 rpm. Result - seller is having carbs cleaned.

My questions are:
If seller road bike like this, could any other, more expensive problems been caused by ******* the bike to keep it going?

I had to really overclutch to avoid launching out on one wheel - is the F4 clutch a wet or dry clutch?

and

Could the stalling as soon as you give it a little gas be a bigger problem other than clogged carbs?

Thanks in advance!

 

You'r carbs aren't Clogged per-say. But really the jets are stuck some what in a high position stoping the amount of fuel it need to run from entering to float bowl. tha's pretty much tha "jist" of it. Also I wouldn't run with the old gas, it's gota be dripped out tha tank and the carbs gotta be rebuilt. VERY IMPORTANT-- when the you see the carbs again try to check the gaskets. Any air leaking in/out will help it stumble some more so make sure they're good. If I'm wrong or missing something someone correct me.

 

I thought the F4 series were fuel injected.

 

They made carbed F4's in the earlier years. since its been sitting a while and the gas is old, cycle out the old gas out and try again. Was the bike cold or warmed up?

 

In 1999 and 2000 they made the F4. In 2001 Canda/USA got the F4i. In Europe it might have been sold as the F4 Sport.

The i was for fuel injection. With the Canadian/USA F4 it had a banana seat the F4i had the double seat. In Europe the F4i also could have a banana seat it seems.

 

Thanks for the responses -

We let the bike warm up for about 5 minutes all the while having it die like that as soon as giving it a little bit of throttle. But it continued to do it even after riding a bit.

So it's a safe bet to say the symtom is due to the stuck jets here right?

Well, if not - hopefully it will be evident when it comes back from the shop & hopefully I'll get honest explainations - just don't want to pay for something that's supposed to be in really good shape and turn around to find out I bought a project bike.

~paranoid~

 

Along with fixing the jets, replace or clean the fuell filter just for good measure. Let us know how it turns out when you get tha bike back together.

 

Put your hard earned money into something that runs right,, there are plenty of bikes out there for sale! DON'T buy one that don't run good, your looking for trouble, unless it's dirt cheap..... sellers will tell you anything to get your cash and leave you with endless probs'
Would you buy a Bike or Car from a dealer with fuel probs' I think not.
If the seller can't be bothered to sort her out tell him/her your not interested.

 

Yea cuz ur advice really helps his carb problem..lol.. not true anyway dirt cheap!!! thas a shady deal.

 

Hey guys, I thought carbs needed to be redone about every other year anyway?

It's not coming dirt cheap - $4K - but if it comes back running right, what's the risk?
