Tuning the 8V

Hi All.

A little advice needed on tuning the 8V. (2010 GRiSO). I have set the tappets and they were out a fair bit. Started the bike after that and all good. Decided to wash the bike top to bottom and wouldn't start after. Spark plug leads are a bit old and spark was tracking to the head. Dried them all out and bike started again. Took bike for a spin and ran OK. Bit of popping and rough idle. Turned off and went back after 10 mins and it would not start at all. Lot of popping and back fires. Finally got running, but shit at idle. I can still here spark tracking.

I am going to change the spark plugs and caps to NGK SB05E (Thanks for the number Pete) and will put together new wire leads for it.

After this is done however I would like to tune the airflow etc and balance the cylinders as setting the tappets does alter stuff. I know there has been a lot of talk about tuning and balancing.

Has there been a thread (and if so can someone point me to it) on a step by step how to for the balancing and tuning. I will only have to be shown once as it was some time ago (30 years ) when I was tuning my GTR XU1 with a stethoscope.

Thanks

Thanks Stake.

I will order all the gear.

Can someone direct me to the latest version of Guzzidiag for the 8V and does it take care of everything ie: TPS resets and maps if need be. I have seen some links for the cables (2 of) and I will order these.

Has someone got a photo of the laptop, cables etc all hooked up.

Got to say that I am loving getting the hands dirty again and working on the bike.

Cheers Mark

Just search for 'Guzzidiag' it's all here. It does require some effort on your part to discover what you need but it's here. Not being unwelcoming or anything but if every new member got a personal step by step the board would fill up with identical posts and we'd all go bonkers!

Really, we'll fall over ourselves to help people sort shit out but there are only so many hours in the day and we all have jobs.
