There is a small "Slit like" Gap around the top of the pipe where it connects to the motor. Is this normal. Or do I need to fix it? Just trying to get her ready for the 1st ride! ;D
Its around the top where its hardest to see "Of course" Idk if this is a problem or not. It may be normal but if it isn't im gunna fix it now.

Looks like they have the wrong (weaker) pipe springs on your bike.
-
What? The springs arent strong enough? they seem to be pretty tight to me.
-
They don't really look like proper exhaust springs too me, they seem really thin.
-
hmmm. What would be a good temporary fix?

So i guess i would have to take the pipe off and bend it down?

They are not the proper springs.
Get some from a dealer, they are pretty cheap.

Yes the springs do need replaced, cheap and easy fix. When you take the springs off, I would also pull the pipe off, clean everything, and add some RTV hi-temp silicone sealer when reinstalling the pipe to ensure a air tight seal. The RTV hi-temp silicone can be purchased at your local auto parts dealer.

Thats what i was gonna mention, some silicone, seals and springs together with a good clean and she be all good..

Everyone's touched it. Quick and cheap maintanence. The springs and gaskets are some of the simpliest you fix'em parts on the bike. You'll get the feel for what your bike needs and how often the longer you ride it.
Now quit nit pickin the damn thing and go ride. :P ;D

I have respect for ya Coop as I do for every 2-stroke fan on this site but you just mentioned to Brapp that they were the wrong springs twice where as the Kiwi said to go get the proper ones from the dealer which I thought that was the most logical advice.
-
...but you just mentioned to Brapp that they were the wrong springs twice where as the Kiwi said to go get the proper ones from the dealer which I thought that was the most logical advice.
Hmm my bad. I assumed when you tell someone twice they have the wrong springs it's implied they should go get the correct ones... ;D :P

guys, guys, guys. There is room for everyone's opinion lol.
Anyways, Pulled the pipe and silencer today and got them both completely oiless. gunna get the FMF pipe and o-ring kit as i heard its the best. About to go to walmart to get some clamps for the exhaust hose "as obviously i had to cut the old ones off :)" And as somebody mentioned before to get some RTV and I did. Picked some up at the AutoZone a few days ago. So everything is nice and clean and will be sealed perfect ;D
-
This week is looking to be a good one! On wed my fmf pipe spring and o ring kit will be in along with the spring puller ;)
And on thurs my new Jersey, Pants, Renthal Bar pads "For the Renthal Handle bars of course :)" My oil plug and some stickers i bought :)
Now for the questions. I figure RTV stuff shouldn't go where the pipe connects to the motor as it may be too hot and with new springs and an o ring is shouldn't need it right? And i plan on using the RTV to get a solid seal where the pipe connects to to the silencer.
-
You can buy high temp rtv.
I just use abit of grease on the new o-rings to help it slide on and seal. High temp grease of course.

No guarantees but that spring on the left is definite NOT an exhaust spring and much too weak. You did the right thing by ordering proper springs.

Braap,
If the "O" rings are fresh, you shouldn't need and RTV sealant. The o ring won't melt, but they tend to go hard after a while and lose their sealing quality.
The goop that's leaking out of your header pipe isn't caused by poor sealing at the cylinder, it's caused by overly rich jetting.
Put on fresh springs and "o" rings, get your jetting right and your problems will be cured for good.

Well, When i pulled the pipe off i don't believe any O-rings in were in there. But they will be in there soon enough. And i wasn't gunna use RTV on the around where the pipe connects to the motor. I was gunna use some for where the pipe connects to the silencer. As for the jetting, Yes i know its too rich. But I don't have the time to jet it myself right now. And being as I have never done it before it would probably take forever. I wonder if there was someone in my area who could do it for me?
