Checking/adjusting valve clearance

[tnarg]

Just a quick question, those with 4 strokes how often are you checking your valve clearances?

[Paul in NZ]

Depends on the engine, use and ease of doing so...

Old GS1000.... Every 20,000km I suppose....

Old Triumph... Every 5,000km

[GR81]

just as well he is talking about a '06 kx250f then!

[4stroke]

depending on use.. motorcross prberly every 10 hours
trail rideing i do mine every 20 -25 hrs some people may do them sooner.
what does the manual say??

[Buddy L]

i checked mine at 14 hours didn't need adjusting as the tolerances were well within the limits, ill check again in another 14-15 hours

Modern 4st MX around 10-15 hours of racing.

Old 4st enduro around, ummm, 4 years now...
May have to check them sometime.

My DR650 around 450-500 hrs or so but was still within spec.

06 KX250, if you are racing, approx 15 hours, trail riding approx 25-30hours,

Depends if you are a top 5 finisher--if not 20 hours if so after every meeting

Just another reason to love 2 strokes.......

Like when I was serious about my R/C off-road electrics. I would strip, clean and rebuild the motors after every race.

Cheers guys just making sure im on the right track with my servicing.

I check mine every oil/filter change but im pretty paranoid when it comes to my bike (the bikes doing my head in , time I went to a 2 stroke .YZ250 here I come.......)
