Breathing, on the S1, it still feels stuffy.. a Question then? Drilling Baffles.

Mates rd350 [ aircooled] was door also wolfie, we cut 100mm off the baffles and drilled the holes,, worked wonders,

Interesting, I wouldn’t have expected it to make any real diffirence, especially if you’re using packing wrapped around the baffle tube.....

Have you thought about lowering the gearing back to std. I run 1 tooth less than std on the rd front sprocket so that i can use and pull 6th...... otherwise 6th is only usefull going down hill

I presume a nice shiny set of spannies are out of the question.... those Higspeeds look cool on a triple !!

Are the exhausts OK then Gra and not coked up?
There is a lad lives near Ruddy(can,t remember his name) has a stunner of a KH250 and he had the same problem turned out one of his exhausts was coked up.

how did this end up wolfie?

and how much is that for a session in this day and age?

Not sure Al,,,, if you go to the NERDOC bash you may be able to win an auction for a dyno session for the price of a few beers

I don't know anything about anything Kawasaki's but isn't that that transition point between the pilot circuit and the main jet?

In Yamaha's, the pilot circuit has an effect right though the rev range but flat or even misfiring in the five to six thousand rpm range usually points to a pilot circuit issue. Might be worth a look to see if all is clean, as in RD carbs they seem to gum up for a pass time.

I've usually been amazed by much crap comes out of seemingly clean carbs in ultrasonic tank, but it doesn't sound like it will be the answer

The trouble with ultrasonic cleaning is that the dirt needs to have a gravitational escape route once it has been loosened, i.e. if its in a gallery it wont necessarily find its way out.. the best way is to do them several times in different positions... a good blast of compressed air will also help once the shit has been loosened by the vibes..

I think this is one of the reasons that you have to drill out the brass balls from the yam mikuni's… there isnt any other escape route...

yeah its a tough one this because I wanted my yam to have balls but I was told to drill them out

ended up mine never had balls but I drilled it anyway.

a good way of telling which jets are blocked is ride the bike in third gear on 1/8th throttle and let it rev as high as it will
that's the pilot jet
then open throttle 1/4 and try again and that's a combination of needle and needle jet with the throttle slide cutaway also adding its sexy influence plus the pilot tips its lot in as well

then try it at 3/4 or full throttle - that's the main jets, you are trying to rev it right out past the red line and towards the dark side of the moon.
what you are looking for is the tell tale squeak that you have either bats or mice nesting in your airbox
(don't say you have pods or k&n's)

in theory you can take out your main jets and if you only open the throttle an 1/8th the carb will only draw fuel from the pilot and ignore the great big massive hole where the mj was
(not michael Jackson btw)

my first line of attack would be new or clean air filter
new plugs
check ignition timing' and check points for excessive arcing

check you aren't using old fuel that has absorbed water. to test for this drink half a pint and then set fire to your breath. make sure you have life insurance and a recent hair cut.

not revving through could be simply a sign of old age. have you recently checked the bike over for arthritis or dementia?

if you are over rich it four strokes or stutters will go as well on half throttle as it does on full. if this is the case you can do an online bank transfer to my account

ive just spent the last month fine tuning my puchs carburation and it gets hard when you are nearly there as its not easy to detect a tiny bit weak or rich and plug chops are the only way unless you have access to an af meter
you can do plug chops on part throttle half throttle and 3/4
doesn't have to be full throttle or in top gear flat out.

it might not be the carbs ignition or indeed anything wrong with the bike but your wrist

I know its a young mans game but does your wrist get enough exercise nowadays wolfie?

id love to have a go an an h2
I went to buy one of a Scottish guy called neil in wakefield ex racer? imported bikes with rick brett? who had 2 x H2's and an (re5)

I ended up buying my rd350.

virtually every nut and bolt was not tightened properly

it really must be a wrist thing with H2 owners....

we'll have to swap bikes sometime this summer if we get out.
as long as you promise not to thrash the living daylights out of my yam . . . .

ive always wanted an H2 but prices went mad around 2011

ive done my puch m50sports up over the last few years and ive just bought a Paloma moped. pick it up tomorrow. 1960's French thing. thoink only the rust is holding it together

i'm determined to get it going 60mph

me and the lads I go with swap bikes now and then, mostly big sports four strokes

last year was out with a couple of pals plus shag on a classic old blade over in Lincolnshire with its twisty roads

I swapped with my pals ducati 916
he rode my zx9r - which he used to own a long time ago

I overtook shag going into a bend - (it was only his first outing with us and was a bit rusty) and then cranked it over expecting it to go round the bend in style but instead it was stuck at the angle of lean it wanted to go - which sent me across the road towards the opposite verge and no matter what I did (mostly panic and shit myself) the bike was not for turning

it was the most unwilling steed i'd ever sat upon
it only seemed to do what it wanted and you just had to go along with it and learn how to ride it

my dopey zx6r and zx9r's you just sit on em and bully the fook out of them and they seem only too willing to comply

mad innit

maddest experience during bike swap was with my pals zx10 and he rode my zx6r

his was fast rigid and I was scared of it
he said mine was underpowered and boring and real easy to ride
he went round a few bends enthusiastically and then was tooling along at what he though was 95 only to see the needle at 120
he couldn't believe how it insulated him from the road and just seemed to glide along

no hard suspension set ups for me.....

lol modern, my zx6r is 19 yrs old, the zx9r is 21 years old, the ducati is 25? years old

nearly as old as us!!!

the zx6r is my fave bike, the yam is too scary once you get over the ton the 9 has a tiny too much power for my uneducated right wrist but the 6 is ace cos you can just hammer it everywhere (apart from in first gear) and it doesn't lose grip or point to the sky.
at 3 figure speeds you need less of the boneshaker/ penny farthing experience and a bit more insulating so as to enjoy the actual experience

but I know what you mean wolfie, that's why I haven't tweaked or replaced the brakes or suspension on any of my bikes to make for a nicer ride - especially the 350 and ridden them how they were meant to be ridden.
