How long till you need a need clutch...

I know that is a relative question but aprox. how many runs will you get off a clutch? Does it help the clutch by putting a fan on it in between runs? I've seen people do that but i always figured the oil is supposed to cool the clutch down. But i wondered what others thought too.

The clutch can last...........But there are many variables.

Variables such as.......

1) OEM plates v. Aftermartket plates
2) Barnett springs v. OEM springs
3) Using good petrol & maintenance practices
4) "Dump"......"Feather/Slip"......"Ride" the clutch

As an example our "E" has more than 110 passes on the clutch. The clutch is still in good race condition........But I will be replacing the clutch cable w/ the motor R&R. The parts, etc. used:

1) OEM plates
2) BARNETT springs
3) MOTUL 5100......E-TECH 100 (since December 2000)
4) All pilots; (brother) Chaz, (racer) Joe Silva and I "slip/feather" the clutchl.

This combination has proved very "consistent", "fruitful" and w/ minimal "breakage" for use. YOUR RESULTS MAY VARY!

Hope This Helps!

Thumbs down How much do you slip you clutch...

If it's not slipping...

Keep it...

When you rev the bike in gear, (it's slipping & getting hot.)

I inspect the clutch every time I change the oil...

If it looks good, I put it back in...

If it looks like it slipped, then chances are the springs got hot & the clutch will need new springs, if the plates are worn, get new plates, clean the steel unless they look really burnt, then buy a new clutch...

Inspect the basket & hub for cracks...

I still have a stock clutch, but when it's time to upgrade, I'll look at what Johhny is doing, it sounds like it works...

I just put a Muzzy clutch in my buddy's ZX12, but we all know that the early 12 had a bad clutch to begin with for a motor that makes over 150 horse power...

Don't slip it & it will last.
