Help Hey, need help with my 1997 GSX250f

Hey i bought a gsx250f 2 weeks ago and its been 1 problem after another, the main things that are the issue that i'd like help/advice with are...

Carby: the idle goes "hunting", I have pulled the main parts of the carby apart and cleaned as much as I could (I didn't want to totally dismantle it without a diagram handy), also a few times ( only when hot I think) and I try to take of at a a set of traffic lights and when the bike should start to take off it loses ALL revs, when it does eventually take off it feels asthough the hole 16.5 rev limit is the same as having 2k revs. the fuel filters look very clean, although i have not check the mesh filters connected to the petcock. Also if anyone can help set the air/fuel mixture.
How many km's does everyone get out of a full tank of fuel?

Valves: while i'm changing ripped gaskets and re-doing coolant and everything I thought I mays well check valve clearences. I found a tutorial on here which Is a great tutorial but the way the lobes sit I think it may be out of timing, can anyone help me to work out if its in timing and if it is to put it back right.

fuses: i'm not so worried about this one as i think its just a faulty connection but a fuse has randomly blown a couple times. did anyone else have this issue?

fork seals: i'm changing the fork seal as they are both ripped. Does anyone have a tutorial?

overheating: It seems as though its getting too hot, i am doing a coolant and oil change, is there anything else i should check out or change?

I do have experience working on my other bikes and i am very handy with tools so that is not a issue, its just i dont have the knowledge on this bike and i dont want to take it to a mechanic as i've had bad experiences. I did buy a mnual online but it is a very poor photocopied version which you cant see the pictures or read all the words.
I even got a mobile mechanic to do a pre-purchase inspection and he cleared everything (except idle hunting) saying it was a good bike which is why i paid the higher price, but he missed 3 obvious fuel leaks, and obvious oil leak, and the bike only had about 800ml-1000ml of oil in it. not even showing on the eye glass.
My name is chris, i have a gsx250f 1997, its a AWESOME bike, and appreciate any help. Thanks
[ I will upload pictures this afternoon]

 

Thanks for the input, is there another way of balancing carbs or do i need to buy a carby balancer? (if so i'm looking at these 2 ....

what do you think?)

I'm checking leads tonight, i've already bought new plugs but i'm going to inspect the gap on the old ones anyway.

Are you saying the pilot air/fuel is factory set at all the way in then 1.5 turns out? cause mine was set at all the way in then 3 full turns out.

What part of the float do i measure to check correct float height?

As for timing, the only thing i could find in the manual was on 3-51 (i'm having troubles uploading pic), have i missed information in it somewhere else?

Thanks, Chris

 

i was going to put a switch in for the fan to be either ON or sensor (how it is now), but now your saying battery drain might be an issue i might hold off.
Last tank i got about 50-60kms (not a spelling error), i wasn't down to reserve but i filled it up with about 9-10 Litres. With the fuel/air screw is the further you undo it (anti-clockwise) making it richer, and the further in it is (clockwise) the leaner it makes it? cause mine was set to the whole way in, then 3 full revolutions out. from what kiffsta was saying it sounds like it may have been very rich, and both my fuel sensor bolts (underneath tank) had a small leak, and 1 float bowl in carby was leaking. All the fuel leaks are fixed now though

 

here's the only thing I could find on timing. Is there any more info in there?
thanks

 

Cheers man, i bought one off ebay but it was alot worse copy then this. And i'm happy donating that money to gain access to it

 

looks good, defiently will!!

 

ignore this, i found more under "tappet clerance" and my timing looks good compared to above pic,

Same one as i was looking at, http://www.ebay.com.au/itm/4-Column...003198?hash=item43b0803d7e:g:bNIAAOSwdvpWDaCL. i'll get that one. Cheers mate

 

Thanks, i sent them a e-mail about express postage. Its the same price as on ebay anyway.

 

when changing the spark plugs, one of the leads came out of the boot, so i trimmed it back but it didnt feel like it wanted to go back in. Is it the standard leads you can trim back or ONLY aftermarket leads?

ok guys.... bike will turn over but not start. timing is good/ carby is good/ spark plugs is new/ battery is good/ compression is good on the 2 outside cylinders 150psi, with my compression tester i cannot access cylinders 2 and 3. HOWEVER i am getting oil on 3 out of 4 spark plugs. Any idea why i would be getting oily spark plugs with good compression and what else could prevent it from starting. Thanks

 

i think my left side coil does the 2 left cylinders, right side coil does 2 right side cylinders. so your saying the left side does outside cylinders, and the right coil does inside cylinders. is this also for a 1997 model
