so I was rebuilding a kfx400 and once I put it all back together I messed up the timing and wouldn't start so I took it apart fixed the timing put it back together then it started up sounded good and then died, now it just sounds like the starter is working nothing else ??? does anyone know what...

do you know if I can just un do the box and point it down towards the ground like other bikes ? and no I did not but I had already bought I richer jet bc I have a yoshimura pipe on it right now and it's running really lean

so I decided to buy a k&n air filter because I wanted to take the air box off of my 80 and when I was taking the air box off there's a little hose connecting to it coming from a little box on the frame that goes to another hose in to the engine ? I'm imaging it's just a excess oil or something...

I'm only replacing the float needle because I can't seem to find the seat anywhere and I'm not really sure how to get it out even if I did get one and I think my float height might be the problem because the way I had it wasn't moving enough and getting stuck open so I made the float height...

I have went through 3 float needles now???!? each one ends up deformed at the little rubber tip and I can't figure out why does anyone know because when it does this it doesn't hold gas and just floods the engine

figured out the problem , the float needle valve was bad it was stuck open so I replaced that then it worked for a solid two weeks but then somehow it got like sucked inside where it sits and the rubber tip got mangled ???? so I had to buy another one and it worked but just today it died once...

I checked the reeds yesterday because that's the only thing I could think of and they weren't cracked or anything and I couldn't see any light through them so I think they're okay. and I haven't checked the compression but I just rebuild the top end probably two weeks ago so my guess would be...

I have a 99kx 125 and recently I power washed it and drained the gas and put fresh gas in it- 35:1 and then started it up and it was just idling then it bogged down and died. so I tried cleaning the spark plug and no chance of starting and then I tried starting fluid and still not starting and...

I had it warming up just idling in my garage for maybe 15 minutes , then went out and had it about 3/4 throttle when it died and would not rev at all. yes I know and it was running really rich which is why I got new jets. I have cleaned the carb about 5 6 times since I had it, and everything was...

have not done leak down test but there isn't any noticeable leaks, I have everything torqued properly with brand new multi later steel gaskets I think it was. I went down on the main jet and up on the pilot, the pilot that was in there origanily was a 40 and main was 155. . stock main is 158...

so I got a 1999 kx125 and I was gonna ride it one weekend and I got it warmed up and as soon as I got it in first gear and went about 5 ft it bogged down and died. so I bought a rebuild kit for it *needed it anyway* so after I had got the bike working again with the new piston I decided to go...

I know I post a lot guys but don't get annoyed just yet. When you remove a flywheel along with the stator etc.. is there timing? if I were to completely take the flywheel off and change the seal is there a certain way you have to put it back together or can you just slap it on ? Thanks

I doubt anyone would know but does anyone know what the left side crank seal size is ? Thanks anyway

They do use an actual gasket but I just want a temporary fix . If possible. Also you can get the crank seal with a nail and screw , not the best way but it'll get it done

And what size jet should I get ????? Idk the sizes. Also could I lower the jet needle clip?

can I use permatex high heat gasket maker to fix the leak between the split of the cases ? And when replacing the crank seal is there timing on the flywheel? That's what confuses me

it is leaking from the crank seal. Only when it runs. It have a fmf not stock. And yes it is keHeinAfter running I thought it was running rich because it would bog when it hit the throttle fast. So I bought a hotter plug but I took the one out and it was dry and kinda white like a lean plug...

The float height is correct. It is set on 16mm. I have cleaned the carb recently and got it as best as I could. Fresh air filter. Not sure what a plug chop is. Could you explain ? And yes the carb is stock. I have v force 3 reeds fmf full exhaust. Air box lid off. That's it about engine parts...

So I had found out my 85 had been running too lean... And wasn't getting much gas; probably why it wasn't starting. Also found out I have a stock main jet 125. And Idk how the sizes go. Could someone tell me what size I should get for more gas ? And how I fix the running too lean problem

do you think I can switch my rm85 carb with a blaster carb that is tors eliminated ? Just wondering bc the carb on my 85 is junk and I have an extra carb for a blaster laying around
