Hi,

Any recommendation on a machine shop to get my Gas Gas's head machined for a different cam?

I'm not opposed to mailing it out, but something in the area would certainly be handy.

Thanks,
D

Not sure if he can do the work you're looking for, but worth a call.

I've been going to Ron for 7+ years, he does great work and his prices are good. While he focuses primarily on 2-stroke stuff, he does 4-stroke work as well.

Please tell him I sent you, if you go.

Hey thanks! It's nothing tough, just some clearance work to fit a DRZ hot cam (better decompress mechanism)...even a machining newbie like myself could do it with a mill.

What needs to be machined? Is this for teh decompressor? Are you doing a manual one? Where you need to bore the lever hole? There shouldn't be any clearance machining required to put a Hotcam in a Dizzle.

I thought the stage 2 exhaust cam is a bolt on part for the GasGas?

I'm going with an automatic one, to replace the current automatic one. Gas Gas one is known not to be the best and the stage 2 DRZ Hot Cam seems to be the ticket.

Interesting enough side of the Gas Gas head has the same casting as the DRZ where the manual decompressor would go, but obviously no machining done.

Would I be better off with the manual? Never had a bike with a manual decompressor so I'm out of my element a bit on pros/cons. Cost wise it's pretty much the same between the hot cam and all the parts for the manual assembly.

There seems to be plenty of research out there on it:

The only difference between the two cams is how the cam gear is bolted to it

Machined Gas Gas head for the DRZ cam:


Gas Gas cam in that head


DRZ hot cam in the same head

That head is not off mine, but off a 05 450 FSE. Mine is a 03, but I'm expecting the same. The exhaust cam shown in that pic is not right, it's missing the decompressor. What year is yours?

I have an 02. It's a 400, but the heads are the same.

I have a fly wheel extraction tool and know the OE part number (Ringspann) for the starter clutch if ever are in need btw.

It is a problem isn't it?

Mine doesn't even run right now, and I'm not sure why. Need to spend more time with it.

Mine runs really well once it starts, but right now it's nearly impossible to start. 2% of the time it starts on less than second of cranking, the other 98% it just says "No...fuck you!" Funny for a fuel injected bike. They are certainly finicky, but man are they fun when they run
