KTM Freeride - Fuel Injector

Injectorul de carburant la KTM Freeride 350 - O piesa prea sensibila!

Injector KTM Freeride 350
Din pacate orice lucru bun are si dezavantaje, cum ar fi Injectia electronica a KTM-ului.
Cum ati mai citit sigur pe net sunt multi care au avut probleme cu acest aspect si au fost nevoiti sa traga pe dreapta si sa astepte service-uri scumpe pentru a remedia problemele.

Va povestesc putin despre acest sistem de injectie si sper sa aduc cateva info cum sa evitam probleme in viitor la sistemul de injectie KTM.

Ce este interesant de stiut ca sistemul de la pompa de carburant care se afla in rezervor si pana la injectorul propriu-zis avem instalate patru filtre si site!!!
Deci filtru pentru filtru...LOL!!!

Unu: Pompa de combustibil are in sorbul ei o sita care nu se vede decat dupa ce faci pompa bucati si dai jos sorbul negru din plastic tinut de patru urechiuse.


Doi: Filtru de carburant din hartie in rezervor. Acest filtru, un Mahle KL 97 destinat sa filtreze carburantul este foarte fin, si se poate obtura repede.














Trei: Microsita pe conducta la nivelul cuplei rapide. Aceasta micro-sita a fost conceputa de KTM la 10 microni, ce a dus la obturarea ei foarte rapida si a fost inlocuita cu micro-sita la 20 de microni. ele se deosebesc prin culoare. Cele negre sunt de 10 microni iar cele noi sunt gri. Aveti grija sa le schimbati regulat sau macar se le suflati cu jet de aer pentru a le curata.


Patru: Sita din fundul injectorului Keihin. Aproape invizibila se afla in fundul injectorului o sita care eu inca nu am reusit sa o scot.

KTM timing marks for Cams

Did you ever search the timing marks on a KTM which indicate the correct positition of the Cams in TDC? Well, here's the secret: Loook in the opposite side of the Timing chain for the two marks which have to be both visible when in correct position. If necessary turn you Cam until both marks are visible.

Had a Cam Chain tensioner failure ...

After riding uphill I stopped and laid my FR down. Starting it up again, a rattling sound... end of story. ...fact is the hydraulic Cam Chain tensioner or also called the Timing Chain tensioner of my Ktm Freeride 350 stopped its duty cycle causing the Cam to turn over one tooth. Luckily on tooth didn' t damage the Valves, so the got no hit from the cylinder and didn't bent or even break. That would a been a disaster. This is how the Original KTM hydraulic Cam Chain tensioner looks like: Normally oil pressure is even too High causing too much wear of the chain. Testing my hydraulic Cam Chain tensioner on a flat table, pressing it down it remained blocked. It should not happen after only 70 hours. Conclusion:  I will grab a new mechanic Cam Chain tensioner from Mito Racing and get rid of any trouble and noises coming from my engine. Adjusting the new Mito Racing Cam Chain tensioner is pretty simple. I have put a little HowTo and review here.

How to tension your Cam Chain using a mechanic Timing Chain tensioner

How to tension your Cam Chain using a mechanic Timing Chain tensioner... this one is from Mino-Racing This is the buddy from Mino-Racing which I mounted in my KTM four stroke. KTM uses from 2006 onwards a hydraulic Cam Chain Tensioner which gets faulty after only a few hours. I guess it is mandatory to change the original hydraulic timing chain tensioner with a mechanical one to avoid break downs in the middle of nowhere! In this short Video you can see all action it takes to tension your Cam Chain. You have to pre-tension it by hand first until the Cam Chain is firm and afterward give it another half to three quaters of a turn with the hex. After that you can fix the counter hex and be shure no problems will occur. Check your timing chain tension every 20 hours or with any valve clearance check!
