Dynojet Kit
I have been trying to resolve this massive flat spot I have between 7k and 8k rpm.
The guy I would normally entrust with the work can't do it for three weeks, he has a Ferrari in the workshop where the rollers are installed
"which needs a lot of work"
Jack at Holeshot can do it, but it means taking a day off work, a 200 odd mile round trip in this weather, but at least I know it's been done
properly.
A local bike garage can supply and fit a dynojet kit and set it up for me (although it won't be done on the roller).
Another bike garage will supply and fit the dynojet kit if I take the carbs in to him.
I can buy the dynojet kit cheaper on line than at any of the above three and looking at it the installation doesn't look that difficult. Is
it?
Secoond question is, once the kit is fitted is the fine adjustment done by just taking off the covers and moving the clips on the needle around?
So I could take the carbs off once, fit the kit, put them back on and try it out on the queens highway. If I'm not happy take the covers off,
move the needle and try again?
Cheers
Mike

it can be a bit fiddly lets say a fiddly novice job so be careful and you ll have no probs
THEN GET IT SET UP PROPERLY otherwise youll have engine probs
John cooper could tune carb engines as accurate as any machine by just listening

Fitting the dynojet kit is dead easy, but setting up the carbs is almost impossible, trial and error takes forever, and you need a good stock of jets
and patience. I wouldn't fancy testing the motor flat out (probably several times) in this weather, get wrapped up warm and take a steady
drive to Holeshot.

Does it need a dynojet kit or bigger mains?
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I know I should go to Holeshot, but it's a right pain to organise.
Peteff, I don't know but the dynojet kits come with a range of main jet sizes and needles.

Dynojet kit gives increased fueling in the midrange to combat the lean midrange which causes the flat spot on an open can...
It uses reprofiled needles and atomisers in some cases as well as larger main jets...
If you use the instructions and set it up for a race system, it should be a close DIY job...
You can then get it accurate on the dyno later

Why bother with all the hassle? Even then, it'll still need to go on a dyno afterwards.
Take it to Holeshot and get it sorted. You might only have to take a half day off work.

Kit arrived in the post this morning. Just got to fit it now.
Doesn't look too bad, just got to hope for dry clear day tomorrow to have a few test runs along the coast road.
Wish me luck!

its easy ,you'll do it with your eyes closed.i fitted sheds in 20 mins,,just got to fine tweek it when he takes it out,,but it still could do
with going on a rolling road to get the very best out of it.but if it runs smooth and irons out the flat spots you wouldnt notice much by doing so

'tis fitted. Didn't follow Ox's advice, did it with my eyes open. I know I'm soft but hey. Not very difficult to fit at
all.
Can't tell you if it's made any difference, because it's been raining here constantly for 3 days.

Agreed 100%
Dynojet kits are designed to be fitted by numpties at home, and tweaked later...
Anyone who can build a locost should not fear the dynojet kit
Opinions are like backsides..
Everyone has one, nobody wants to hear it and only other peoples stink!
