What brand of bike ?

Most bikes that have a transmission and take transmission fluid lose some of their clutch slip once oil gets hot

Check to see if your pads are glazed. They may be functional when cool but once the engine and fluid heats up they don’t do the job.

Athena kit is notorious for being hard on the Sachs clutches.

Do you have performance pads or anything like that?

Re: Sluggish when warm

I haven't pulled this clutch apart. I have a braand new clutch from i want to say dos but Mike V whereever he is knows about them. It pulls hard and fast. Then if i go back to almost dead stop or use torque the power just isnt there. Great light trails bike. Need to open my exhaust port too because its running like 15mm at the flange which i can easily open to 18mm

Re: Sluggish when warm

I also thought it might have been the plug being heat soaked.

I don't think porting is the answer to your low-end issue. Again I think it's the clutch if the issues is from a dead-stop after running for a while.

Re: Sluggish when warm

Dont forget, an overly rich a/f ratio will become sluggish as motor gets warmer and run fine when cold. One indication of this is a motor that needs no choke to start cold.

Re: Sluggish when warm

Yup it's the clutch. Sachs clutches aren't up to handling power. It's a shame too it's a great engine otherwise.

Super reliable stock but it's nearly impossible to keep a kitted Sachs reliable. Your pads are glazed over dude. And it's just gonna keep happening.

Re: Sluggish when warm

Its cool. Ill run the end of this clutch and install a new clutch.

Re: Sluggish when warm

The clutch was empty. Better but not perfect.
