AnonymousWell, I’ve been doing some work on the 300 recently and testing plenty of new jetting set-ups in the bike. I’m starting to get the feel for it now, so I will shortly do a post in the KTM section with my findings for others to make use of if they choose.
Last night I was in the mood so I:
Put new grips on and lockwired them up
Changed the main jet to a 160
Changed the needle clip position from #3 to #2
Adjusted air screw to suit above
Adjusted (reduced) float bowl height
Changed preload, damping and compression settings as per Teknik recommendation
Changed shock spring from a 69-250 to a 72-250, adjusted preload, high speed compression, low speed compression and rebound in line with Teknik recommendations.
Changed gearbox oil.
Clean air filter oiled and fitted.
Opened up starter unit, cleaned and packed with grease.
New front tyre fitted (ok well I didn’t do that last night, I will get a shop to do it today
)It will feel like a new bike for the ride on Saturday!
AnonymousNice work Boyz, a little tlc on the steeds goes a long way
Boonit, watch out for that Bling fuel cap on the Banana, they cause some trouble they do :laugh: just ask Chop & now KD
They can be a bugger to line up the thread in a hurry, so there goes your possibilities of winning a Pony Express afte a slow refuel
:laugh:

Quote:Moto,Interested to know why you changed the shock spring. Is the 09 the same as the 10. I haven’t had any issues with my 09. In saying that a mate of mine just bought an 10 400 and he had to upgrade the spring too. He is by no means what you would consider heavy. No jockey either, I would guess 80-90kg dry. Maybe the 10’s have gone a lighter spring or maybe I’m just not fussy enough.
I weigh around 94Kg without my riding gear, so with gear I must be at least 105-110Kg. The bike is sprung front and rear a rider between 75-85Kg which means when I swing my fat arse over the bike the sag is nowhere near where it should be.
Not only does this effect how my rear shock reacts to bumps and tracking the terrain etc, but it also increases the ride height of my front end messing up the handling of the bike.
Don’t get me wrong, it’s not like I can’t ride it as it is, it’s just I’m at the point where I want to get it set-up to work with me so that the bike doesn’t deflect when I hit obstacles (front and rear) and gives some level of confidence.
I changed the spring because it was sat in my garage having come off my old 450 otherwise I wouldn’t have bothered. The new spring will help get me closer to the required ‘rider sag’ and also help to reduce the amount of preload on the spring required to get to that point. This in itself I understand will aid plushness in the first part of the stroke
Until I can get Nick at Teknik to work his magic I will have to put up with the shortcomings as I have ever since owning a dirtbike
AnonymousThe KTM manual says around this, however, Teknik (suspension guru’s) reckon going a bit more and this also seems to be the general concensus for the people in the know.
There is a front sag, and it a lot of bikes it’s measured much like the rear which isn’t so easy to do. The KTM manual does it numbers of turns of preload, being heavier than the springs fitted to your bike you should wind them up too. I’ve just set mine to 6 out from full clockwise and I’ll see how that goes.
I think getting the suspension sorted on your bike will really make a difference to traction, handling, comfort and even your energy level. I’ve grown used to fighting the bike and my front wheel bouncing off the ground mid corner when I hit a medium sized rock :ohmy:
Have a look at Nick’s reply to my post in the suspension forum as it will apply to you to if you weigh close to my weight
