hot start extreme difficulty

[noobi]

ok, problem solved. set the air screw to 1 turn out, problem was much better. played around with it for an hour or so and found 1 and 3/4 of a turn out to be the best setting. bike was very responsive from no nearly no revs in second, i had a few bails just getting used to the new responsiveness.
thanks for the help everyone, i wouldnt have associated this problem with jetting, but glad its sorted

Ok mate,
You don't know the difference between running rich and lean?
Put a 195 main in and go for a run down the street. The bike should run ok on pilot then chug and splutter and not rev out...... this is how it feels when a bike runs rich.
Now if you dare , drop the main to a 165 and do the same run and see how it feels...
If it pings or feels very responsive work up from there.
Ideally you will get a feeling for it as I did .
So long as you interpret the bike and don't rev the ring out of it you will be ok.
It is a pain in the arse changing main jets but a quick and easy way to get a ballpark on what feels right.
I have a 300 and was running a 180 on the 4th clip from bottom.
Changed from 32:1 to 50:1 fuel mixture( which I recommend), Dropped the clip position to middle and then puit a 200 main in.
Ran crappy.
Put a 170 in , ran awesome but thought to be safe I would put the 180 in.
Still runs great although not as snappy, but for me it is better to be a little richer.
Try it and you will see.
Good luck.
Mark

if its lean, will it pink? too much air?
the top end is rich i think. lots of spooge, or have i crossed wires associating spooge with richness? theres too much fuel for the pipe temp to burn the excess, meaning spooge?
i havent changed any jets. still have a 40 pilot. just the air screw was tweaked.

plus, i dont have jets to africa to test. sorry, so cant do those tests.

Pity mate cos that would tell you.
Spooge and richness is not linked as far as I know.
If you can borrow the jets It would help you.
What fuel are you running at what mixture?
Cheers Mark

40:1 castrol TTS. with 96 or 98 where available
iv read stuff about spooge, it could be the oil mix, but it only happens when im on the main jet lots, not during a tight forest ride.
ill try and source some jets from some motox mates, and do the test.

thanks, dale

I was running TTS at 32:1 and had no spooge on the 300 using the same type fuel.
I still would suggest borrowing the main jets to try.... thats what I did.
They were only about ten buck to buy I reckon but a mate had a whole stack which I used to check.
All the best Mark.
