GPZ turbo rattle

Got rattle? I certainly have! I thought camchain at first, turns out it was piston 2 hitting the head due to a very-spun bigend. Bugger.......

Greetings from Hungary! What kind of front suspension you have?

@cilazzr Hi there, its got Yamaha YZF 1000 EXUP front forks, but i think the yokes are custom made so i'm not sure if the original exup yokes will fit.

ouch yeah that doesnt sound cam chain.

have you popped the top and checked valve clearances, and make sure the collets holding the cams on are secure, mine made a similar sound when one had snapped in half..

Sounds great otherwise, love it!

It turned out to a be the slack in a spun bigend bearing letting the piston hit the head! :( Can't grind the cranks as you can't get oversize shells so i'm having to source a new one. Just my luck!

Bugger, never mind my GPz thinks its a 2 stroke, Its burned over 4L of oil in 2500Kms

[InfectusGuy]

Damn, new oilrings and turbo seals then? Either that or bore out to 810cc and fit a garrett t2! :)

Hi there! Need some advice! I've got stock GPZ, not turbo, tell me please about rear wheel. I'm gonna swap it from stock to 17" one on stock swingarm, from what bike should I use the rear wheel to fit it without global cutting and borring? if you know something tell me please, at least the model of the rear wheel. Thnx!!!

if you pull a plug wire 1 at a time you can see if it is it shouldnt knock when it has no spark. and can tell wich cylinder it is.

sounds like a bad rod or spun beariong to me.
