Posted: Fri Aug 16, 2013 9:56 pm Post subject: DB Heavy clutch |
|
|
Maybe this is old theme, but I found out this workaround quite recently. DBs like almost all ducats have heavy clutch and after few drives trough town you end up with bigger left hand than right
There are several clutch slave cylinders to reduce lever force, but this is also simple workaround for lighter clutch. You can add washers to under screws for clutch springs. Here is Ducati original Performance clutch plate manual, which recommends number of washers for specific model.
I tested this and under 120HP you are safe to use one washer in three springs and two washers on other three springs and you wont't get clutch that slips (track use). With DB 7/8 you should be more carful with number of washers… It is very easy to change washers for track or everyday use.
You don't need to buy Performance clutch plate, you can easily made washers: they are 15 mm diameter with hole 5,5 mm, thickens 2 mm.

I can't understand how anyone could say a late model Ducati/Bimota has a heavy clutch. My DB1 and ST both only require 2 fingers to operate, though I use all my fingers for normal riding.
If you want to know what a heavy clutch is, try a Laverda Jota or a Norton Commando. Back in the 1970s I used to commute 80 kms each day, 40 kms through stop-start traffic on a Commando. I used to win all the left arm arm wrestling competitions back then! |

I'm no mining worker… true, but with this, bike is more manageable and pleasant at slow speeds... _________________ Bimota DB7, Bimota DB5 Mille, Ducati 916, Ducati M900, Benelli Tornado Tre |

Have to say Ducati Dave...if youre running standard Original levers and masters on your Db1...you must have fingers longer than a monkeys.....as they "dogleg" the opposite way round...I've changed my masters to gold series with adjustable levers...but kept the resrvoirs atop the forks....at least my arthritic aged fingers can now reach and its less of an effort (and I'm all for that in later years) continuance of riding without achey limbs and joints...Mind you damp cold UK weather doesnt help..maybe not such an issue for you "upsidedowners" in warmer climes.... |

My 08 DB5R has the wet clutch and it is easier than the dry one! My last bike was an M1100 Ducati and that things dry clutch was a bit tiring after a few hours of twisties! _________________ Spike C.

Shhhh Brian...we're having our longest Driest spell for many a year over here...and this biking season I've racked up some 6,000 miles or so on the various Bims....still continuing...Db1 and Vdue tonight just to try chalk and cheese...
Spike...I see your Db5R still has the Brembo Gold series and not Brembo Radial Masters? Is your bike running a standard Clutch slave though? Even so I would agree the wet clutch Duc engines are smoother and lighter than dry...but the "sound" is part of it for me also..sad but true... . |

I have installed a EVR gold colored clutch slave and it is nice! It not only works well butt it matches the wheels and forks! _________________ Spike C.

Jure my DB5 (I think your too) and my ss900 don't have any washer, only screw and springs.
If you want the clutch more soft you need follow hypermotard instructions, increase the washer _________________ http://bcomebimota.blogspot.it/ |
