Hunking

Gads

Hi all, 851 doesn't like going slow or slowing down and starts "hunking".
Are there better injectors available to upgrade the system,

Have you tried getting them cleaned? Clean injectors are happy injectors.

Mr.R

I agree with Griff, but how slow are you trying to ride your 851?
They never did like being ridden at snails pace as in 30mph or under, depending on your answer I can offer a few other solutions.

if it's well tuned it should run nice at all speeds.

Er..."Hunking"???

I agree with you Brad, I've always kept on top of TB balancing, TPS settings, shimming etc.
However my motor ran it's best/smoothest at low speeds after Chris Steedman custom mapped it and before that it ran better at low speeds after I'd lowered the gearing by going to a 40th rear sprocket...

yes, depends what the starting point is and what model it is.

closing valve clearances, closing springs, eprom, injectors, tune set up, gearing, chain condition.

Gads,
What year your 851? 89/90 or 91or 92 serie?
Did it always that "hunking" ( ? I have difficulties to translate/understand that word, sorry)
Can you explain? Do you mean "jerking" ?
