You mean the rocket key? Some clutches dont have any, but the flywheel side always does. is it broken? remove the flywheel like I said in the other post, seize it with rags and use some pry with flat head screw drivers. use some grease or wd40, dont pry to hard so you dont warp the crank case.

if the rad is clogged, trash it and order a new one. your going to need a puller for the clutch probably.

Love the quad and wow it sounds like a beast and so maybe something with lots of Pawer then and so maybe I go for a blata then? Not Polini?

On the keyless clutches and others they glue them on, that's why they are hard to get off. The crank is semetrical you can turn it either way for clutch or flywheel, so you could turn it over if you have a bad slot on the flywheel side you can move it to the clutch side, and glue it on.

That only works on a 47 or 49cc Cag, the GP3 is probably different on both ends of the crank.

When I got my C1 from Tsun in Canada, took 8 days to get everything right so I could ride it. If you have a China bike, and the factory worker screws it up it just keeps going. I remember the insides of the SS chain guards where razor sharp. Have to do alot of work on these bikes, had to shim the engine mount with SS thin flat washers cause it was loose in the frame & replace bolts,etc.
First tools I got that I did not have already was a dremel electric rotory file and a $40 metric tap and die set, that has everything, easy outs and drill for them, spring loaded center punch and all, use it almost everyday. I tap every female thread on the engine & other places, and replace the bolts w/ M6 x 1.0 x how long socket/allen head grade 5, 8.8 bolts. I have some SS M5 x 0.8 x 50mm bolts hold some of my carbs to the intake manifold, and adding a boost bottle helps also.
On splitting the cases, most have 2 or more small pins keeping everything inline, try prying them apart with wooden or plastic piece that is thin and knife shaped edge. Make sure all the bolts are out of the cases and you might want to find out for sure how they come apart.
