Hi guys,
I have been running a CCK needle for a while now on my EC300 07 with an 07-08 FMF Gnarly, but will switch back to the LTR.
It runs very well but fuel economy is very bad. In tight enduro with mostly low to mid and very little main jet I can run it on no less than 4 liters per hour. On an MX track it can drink the same but in half an hour
. Riding behind my own bike I can see the blue smoke, but there's no spooge buildup or noticeable load-up. I have tried to lower the needle and go smaller on the main jet, which helped a little bit, but the problem remains.
The LTR has amazing fuel economy and I can get it to run on about 1.5 liters per hour
when riding tight woods. I know it runs fantastic from low to mid and hopefully I can jet it to run well on top too. If anything its nice to know that Les is a quality guy that can give good advice.
Final setting with the # 7 slide is, summer: 42PJ 1.0 turn, CCK #2, 175MJ. Winter: 42PJ 1.25-1.5 turns, CCK #3, 178MJ.
To the best of my knowledge the bike is running well and pretty well set up and with the air filter decently clean.
