    Re: The "UN" Official Derbi GP1 Thread : Brake Pads

    Hi LR,

    Sorry I didn't see your pm/email till now.

    gpsimports.com.au .  Search part # FD.0380 is the front Newfren pads, but I didn't see anything from them if you do the make & model search on GPS for rear brake pads.  It shows many pads, & I think none of them are an exact fit.  HOWEVER.....

     If you search part # FD.0323 on the GPS site it will show the rear pads you need.  I've been using these Newfren ones with no probs.

    www.metalgear.com.au sell rears, part # 30.146 .  on page http://metalgear.com.au/view_model_details.php?model_id=2144  Searching out the fronts is tricky as there's no pic with pad dimensions.  Be very careful if taking a punt on something that's seemingly the correct fit.

    Example:  I've got GoldFren ceramic carbon rear pads, part # 211.  Appears exactly the same as originals.  The GoldFren fronts (part # 233) I got appear the same, but are a wee bit different, & will have to dremel them out a bit to make them fit = risky business, mucking around with brakes like that ! Stick out tongue   Yet to try them.  Think I got the GoldFrens from overseas.

     

    Kind regards,

    Mick Smile

    Re: The "UN" Official Derbi GP1 Thread : Brake Pads

    Hi Guys,

    Can anyone help me with this speedo problem on my GP1? I've pulled it apart and cleaned it to the best of my ability however it continues to read out speradically, eg it just jumps up and down and is unreadable?

    is it a matter of replacing the cable?

     

    cheers chris.

    could be a broken speedo cable. a break inside the outer casing.

    Re: The "UN" Official Derbi GP1 Thread : Speedo Cable

    Hi Chris,

    I guess you mean that it fails to display the correct speed, & your bike is a last version of the GP1?  

    I'll follow this up  when poss with a pic of how I've done mine.  I put some protective sleeve on it at a place where it could chafe.  I've also re-routed the cable slighty, & secured it differently to reduce flexing of the electrical cable.  

    I got mine from GPS Imports.

     

    Kind regards,

    Mick Smile

    Re: The "UN" Official Derbi GP1 Thread : Speedo Cable

    Here's how I've routed the speedo cable.  Removed original chrome clip from mudguard, & made a more open cable tie version.

    Fitted some tubing as a protective sleeve for the cable.

    The white cable tie attches to the inner bodywork, & is not binding the speedo cable.....it's loose.  The speedo cable is firmly attached further up at a bundle of elec cables. 

    Keeping a smooth flow of cable routing, allow for suspension  & steering travel....minimize bends, & no pinching.

    Kind regards,

    Mick Smile

    Re: The "UN" Official Derbi GP1 Thread : Airbox

    When I was servicing the airbox I noticed a tear in the filter.  The tear was located to the left of the "M" of Malossi, & corresponds to a gap which I've bridged with a bit of tin bonded in place with epoxy metal.

    Also, You can see another bit of tin bonded in place.  This is keeping the plastic straight becaiuse it was warped to a crescent shape, & therefore will not align with opposite half of filter box..

    Am I missing something here? Confused  Are yours the same? 

    EDIT 10.4.15  The torn part of filter was completely unsupported/unclamped by the airbox, & so the vacuum would try to suck it in.

    Kind regards,

    Mick

    Re: The "UN" Official Derbi GP1 Thread : Speedo Cable

    Been ages since I posted anything on the forum. Still riding most days and still enjoying every km on Doc. Have made One significant change to Doc recently and thought I would add it to the knowledge base here.

     

    Couple months ago the seals started going on my rear shocks. My mechanic happened to have a used set of shocks off a 90s MX bike that would fit. They looked pretty ordinary, but my mechanic said they would be a 1000% improvement on the stock ones. I don't know about 1000%, but the improvement was and is phenomenal! Doc no longer gets flustered in bumpy corners or on poor quality roads --> more confidence in the twisties and more comfort on the commute. The ride got even more fun.

     

    As an added unexpected bonus, the improvement in the rear has somehow made the overall front/rear balance of my scoot so much better, to the point that if my front fork wasn't leaking oil I would consider leaving the front susp as is. When my next service rolls around I will address the front - stiffen the spring a little, heavier oil, new seals. If that doesn't upset the front/rear suspension balance then Doc will finally reach his full potential and be an even bigger grin-inducimg ride than he already is.

    Ride safe.
