I'm not compos mentis to make sense..so I'll come and look at this again after I've been to bed....

Basically..no airfilter should make it unusable..as tested by me when racing and a retirement after warm up lap :down:

We'll sort it..

I just need to stop my eyes pointing different directions and tasting of Tyskie... :shock:
Aha :) I was the same...

I reckon (since the carbs pissing fuel occasionally) its really over-fuelling.. akin to having massive jets.

so when the air-filter is removed its made better..

Hehe, was i the only one sober last night?

Anyhoo, Changed all the floats and and valve from a spare set of carbs i had knocking around. Set the float hight to 6.8mm a la Haynes and rebuilt. All is back together.

Now that i have done the tap mod, is the starting procedure(choke, no throttle) the same as there is no vacuum or do i need to feed the carbs manually???

cheers

hello,

Went for a last minute surf break down to Newquay so only just had the chance to let her stretch her legs a bit. She will now pull to the red line but after 10kish rev's looses all umph. :(

I've changed all the float valves and adjusted the float high as above. The front right exhaust port is blowing like a trooper as I'm still waiting for the helicoil to turn up to sort out the sheared thread. How much effect will this have on power?
Also noticed a slight leak from the front head gasket just under where the carbs sit so i guess i will add one of those to the list.

How much impact are these to problems likely to have on performance or does it still sound like a fueling problem??

Cheers

Russ
