How to replace the valve seals

[smug88]

Hey fellow kat riders.

I noticed when I start my bike up, I get a few puffs of blue smoke that dissipates after a minute, and my research has lead me to the valve seals being shot. First question is, is this something I can do myself (fairly engine savvy) and the second question is, should I do it or have it done at a shop?

Do you have access to a leak down tester? That should help you understand for sure if that's the case without having to pull the motor apart.

this isn't really my area of expertise.

I do not have access to a leak down tester.

So, the leak down would tell you for sure if the leak is past a valve or if it's rings.

Valve stem oil seals do you mean?

Yes, I meant valve stem oil seals

A leak down test is not required unless your valves are burnt out or damaged I call it a compression test done dry then wet "With oil" to look for compression loss .As to replace the seals I dunno.
I did wonder if they can be don't insitu using the piston at TDC and use a tool to compress the valve and remove the colletts to get the valve spring off and replace the seal.
I have never worked on the Kats so I carn't help...sorry.
