tuning

Recently sold my 03 FE400 only to buy another. This one came fitted with a Big Gunn muffler which when repacked although a little loud wasn't to bad and has better power noticeably down low. I removed all the electric start gear as I couldn't get it right with my last one and they start so easy...

Hello I have 550 '05 supermoto and it needs a new piston. I would like to now what can I change to get more power out off it? Some 450 are pulling away from me out off the corners and im not happy whit that. :evil: Thanks Husaracer

I've noticed a few spokes are less tight than others and I'm wondering how to approach tightening them. Should I go by sound or rim trueness or both. Any advice welcome.

Hi Well after reading the doc or most of it I thought I should check my 02-03 FE400E donk out a little better as it seems to be getting harder to start with the button. So I remove and clean the carb, fit the missing emulsion tube under the pilot jet, fit a 175 main instead of the 185...

Hmmm Dellorto 40 on my FE 501 ... In in effort to soften the power from zero revvs, i finally got round to fileing the mouth of my throttle slide. To be fair it seems a bit better, but is now not running right. Obviously i increased the air jet - twice actually and am currently at 52 !! It...

Hi guys since now having my bike for around 7000kms and not changing a thing on it i am wanting some input. I weigh about 100kg with all my gear on etc 1. After changing gearing from 16/45 to 15/45 the big girl now wears me out in the tight when i try to mix it up with the 450s. I liked...

I'm dialing in my demo 550 motard, and I need some advise... I've got the back-side (sag) set and I am happy with the feel of the rear half of the bike. The push is constant and rear swim is predictable and positive. I can push and pull on the back end with confidence... the front is another...

Hey guys check out this link, its all about stiffening your rear shock spring for your weight, it sounds awhole lot cheaper than the 150+ bucks to buy a new one, and it doesn't seem too hard either. Has anyone tried this? http://www.off-road.com/dirtbike/tech/2002spring/

please help, today my bike went into the local dealer for tuning on rolling road. They have changed the main jet and and the slow speed jet? On the air fuel ratio chart at around 6k revs the peak was going way high, weak i believe. They changed the jets to try to overcome this. The graph...

I have attached what seems to be a comprehensive guide to tuning. Might come in handy on my quest to tune my beast and get more petrol into the motor than out of the overflow. Was looking in the Doc but not much info for 600's and the Dellorto. Might be handy for older berg owners. Was...

Well I got my Rekluse for my 04 550 and installed it last night. Bike started right up with no drag at all, idles great and seems to have good hook up (no slipping) however, I opted to keep the clutch lever but it does absolutly nothing at the moment. limp throughout the pull. the bike is...

Here is my reply to an Email regarding a heavy throttle hesitation with one of my Jet Kits. I believe said reply will prove of overall benefit as it is not specific to my product. Hi Giorgio. Completely warm up the engine by riding. Adjust pilot fuel screw plus / minus one turn from...

Food for thought: I own three dynamometers one of which is mobile. Gather enough interest (ie money) and I can be most anywhere. :lol: Dale

hi all guys, a problem has occured with my husaberg fe 600 and its phm 40. it is impossible to make it idle correct, the idle screw behaves more like on-off switch (when i screw it in there is no linear response to the idling speed) and as for the mixture screw i had to screw it all the way in...

I rode my 450 today on my Hare scramble/grass track. To keep the front from diving when decelling, I installed 4.6 springs and ran the stk 80/250 spring in the back. After a few laps I softened the fork compression 4 clicks and the high speed on the shock by half a turn. It seems very good...

My 02 Fc470e starts and runs great at sea level-however where i ride fluctuates between 4500-7000 feet the bike gets finicky and wants a slightly cracked throttle to start, button or kick. it wont idle and when it does idle if i crack the throttle a just a bit it wants to wheeze and die. when...
