Grind Away!

Mad Dog Bianchi · 02-May-2005, 09:48

Just took a ride to see the Japan Indy 300 at Honda's Twin Ring Motegi. They have built an oval there for Indy cars and Nascar. Pretty fast, pretty loud. Anyway, the STs4 was a pleasure to do the 360 km round trip, but I am a little bothered by the semi-grinding noise that comes from around the rear suspension when leaving a stoplight. Had the same kind of noise on my Gilera and never figured out where it came from. It occurs in concert with the front supsension rising and the rear subsiding. Any ideas??

Typical noise a ducati dry clutch makes when it needs cleaning out.

You mean after only 2300 km...My Gilera doesn't have a dry clutch, but makes the same noise. Maybe I should stop dropping the hammer at every stoplight....LOL
How did your move go Paul?

Hi again. The move went well, its the last time i do it myself though! Still loads to do including fitting a new bathroom suite and building a shower!

2300 km isnt a lot to be honest but i have found that if you are a bit keen with the clutch then it can make that noise quite easily. Mine is worse two up becasue i use more revs. If you are used to jap clutches that are mostly fit and forget then i guess its possible that you could have generated enough dust in that time to make it slip a little.

yeh, STs kinda get a glaze+dust combo coming. Use it as a prompt to learn better clutch control

I replaced mine with the 48 tooth setup. Soooo much quieter and no grinding yet.

I found a 14 tooth front sprocket helped quite a bit as well.
