Got em. Here are the sizes. 2-123 (at the base of the silencer) 2-132 (at the head pipe/ mid box connection) The part #s are standard Oring sizes found at any hydraulic or seal place. And are readly available from industrial catalogs too. I went with Silicone. They are more resistant to heat than Buna.

The topic says it all. Need some new sealing orings on the 315.

Lots of cross checking has led me to this. Stock Honda CRF250F filter Hi Flo 116 K&N 116 Sweet!

What K&N # is the right one? 112? 116? Is it the same as a Honda CRF250F??

I have this same issue with my 06' 4rt. After a ton of trouble shooting I have found that there is no spark, unless you kick it like you want to kick the foot peg off the bike. 1 very hard kick produces a spark. Any sort of lazy kick, no spark. It drives me crazy. So crazy that I just bought a 315 to see if I like it. What I like is it starts on the first kick. Every time! Once the 4rt is running it does run really good. I have found 2 slow kicks followed by 1 really hard one will start it. If the idle is so high that it is crazy. Yes it does seem to start with 1 kick. But again, other guys with 4rts don't run the idle this high and have no issue starting.

Clockwise is more damping on compression and rebound. Same with the rear shock.

Let me know what you find. What do you mean HT lead? Do you mean the plug wire? So you are saying measure from one of the primary terminals to the plug wire? I have tried the tickover thing. In the past this has gotten it started but the bike is screaming. Probably 2500rpm or more. I do have a pretty fast idle going. And this does help. But does not cure this problem at all. And the reset is key to know just in general. It helps if it doesn't start on the 2nd or 3rd kick at any point. But again....... doesn't solve my starting problem after sitting for a while. Can one of you guys try kicking it and watching the spark on your bikes? And notice how hard you need to kick to get spark and at what point does it spark?

Here is the deal. 06 4rt 65hrs on it. If the bike sits for a week it is pretty tough to start. Once started it runs great. Then it will start will little trouble after it is warmed up. Here is what I have looked at so far. Spark Plugs - new ones do not help Throttle cable- clean lubed and loose. Checked valve lash- In spec Fuel pump- Tested with 12vdc and it pumps instantly Spark- Seems to need a very hard kick to spark at all when testing. If I kick softly or slowly, nothing at all. So I think I have some weak component of the ignition. Bad coil? I have looked in the book and it says to test the Primary coil. I did that and it checks out good. And it also says in the same section to check the secondary coil. But it doesn't say what or where that is. What is it? Any ideas will help
