Re: My 2002 Derbi GP1 Scooter Project

When you said you had bought an Ebay kit, I was like... :shock: Good call on the Malossi... :2thumbs: The ebay kit seemed good up until it popped the head gasket, it came down to the head gasket o-ring the kit came with didn't match the o-ring groove on the head. A replacement gasket kit I ordered ...

Re: My 2002 Derbi GP1 Scooter Project

Well the ebay kit popped a head gasket, just under 100 miles. I was heading to work when it overheated, it was running when I turned it off but wouldn't restart. When loading it up in a truck I saw coolant dripping from the exhaust pipe. I all ready pulled the head off, the head gasket o ring just d...

Re: My 2002 Derbi GP1 Scooter Project

Seems as if theres a few aftermarket go-fast goodies available for this. I stumbled across on a few sites. Let us know what you like (and dont like) about these compared to Honda's offerings. I can tell the braking is improved over our good ol' USA standard drums. What else? Yeah the amount of afte...

Re: My 2002 Derbi GP1 Scooter Project

What a nice scooter. Italians make nice designs. :smile: Thanks, The styling is what attracted me to this scooter, they have pretty good performance too. It rides nice but I'm still getting used to the quick take offs from a stop, maybe not the best scooter for stop and go traffic. The drive face h...

Re: My 2002 Derbi GP1 Scooter Project

I've been on a couple test runs and it seems to run okay, but it needs some re-jetting. I'm using the k&n style air filter that came on it but it bogs at WOT, plug looks like its running lean but gets up to around 45mph. I tried to put the modded stock airbox on and now it runs too rich and only get...

Re: My 2002 Derbi GP1 Scooter Project

Greetings: Good thinking on pointing straight to the problem. Usually we end up throwing the wrong parts at it until the problem stops... with the right one. $60 doesn't sound too bad. Are these rectifers made in Italy, Japan or elsewhere? Probably made somewhere in Europe, I think it was a common ...

Re: My 2002 Derbi GP1 Scooter Project

Greetings: Did the fuses blow BEFORE you started the engine, or only after it was running? In the former case, it sounds more like a grounded, short-circuited wire. In the latter, did a new regulator solve the fuses blowing? That's a LOT of fuses... Like, 21? The fuse would pop 4 seconds after turn...

Re: My 2002 Derbi GP1 Scooter Project

I keep blowing fuses just seconds after the ignition is turned on. The engine still runs, but I haven't rode it yet, so I've just been heat cycling it. I figured out the problem was the voltage rectifier/regulator; blew a lot of fuses trying to figure it out. http://i766.photobucket.com/albums/xx310...

It runs, just doing some heat cycles to break it in.

Re: My 2002 Derbi GP1 Scooter Project

I went to install the new top and was torquing the head bolts when a head stud snapped. I was lucky enough to get a easy out to bite and got the remaining threads extracted from the engine block. I'm going to try again tomorrow with just some m6 all thread. http://i766.photobucket.com/albums/xx310/R...
