How many miles have your carbs done?
Good point! I am new to this whole altering jetting etc.

The carbs are like new *cough cough* Only 71,000 km!

You might have hit onto something there :)

Checking through the manual last night, the NC23 carbs you can alter the float level but NC29 are fixed. I may take a look if they're seating right.

The guy I bought the downpipes from got back to me. He was running flat side carbs!

Could try raising the needle by dropping the clip 1 notch.
I tried raising the needle last weekend and it made it run really rough up to around 6000 revs. I tried lowering the needle (clip on position 1) and it was very very fractionally better which gave me the impression it was running rich low down. It was then altered back to position 2 as per the Dynojet setup.

I haven't actually looked at the differences between the standard needles and Dynojet's properly.

The original slide springs have a lower number of winds on them but they both feel similar in strength. They are the same length.

I wish i had my own dyno :grin: £45 for one run at the local dyno is a bit much in my eyes for 15 minutes max. Saying that it would cut my hours down massively!
OTC racing in widnes (01514208781 07841453981) only charges £26 per dyno session (which takes about min of 30 mins inc warm up runs etc) and he is very very good at fueling and setup.
