Fixing the clutch

First trip in to Plentong for 2010

Got my new 2009 spec clutch delivered from Kartpartsuk. My old clutch was totally shot, had to be welded a few times before I can drive. Not only was the new clutch replaced, Jason also replaced all the fuel line to as he said, original Tony Kart.

Counted the chain used, was a 106 using 80 tooth rear sprocket. Same chain for 78 tooth sprocket. Looks like 106 is the sweet spot for chain now. Darn, I bought a 102 chain.

Adjusted brake position to reduce the lag. Meaning, when I step on the brake, there is less movement before the brakes actually does its work. Hopefully, it will give me a better feel on the brakes.

Adjusted throttle stop positioning as well. After the throttle is all the way down, I felt the cable can still be pulled a little more. So adjusted the stop nut so that the pedal can go down a bit more.

After that, it was just cleaning and cleaning. There is a citrus cleaner from 3M that looks interesting, will try it to see if it can clean out those tires marks.

Anyway, with the new clutch, does not mean its better. There are still a lot of reports on the 2009 spec clutch breaking. Have to re-look into my braking. Maybe the Rotax Max cant allow me to brake so hard like the other engines. Cant have this new clutch breaking on me this year. It took a 25% chunk off my karting budget for 2010.

Next Race. 7th February.
