wow, I've used my 2007 CRF for 8-9 tanks of fuel and it was a rocket.. If you're sure about putting os tz carb. onto it I may give it a try

BTW, we had no tuning issues with the engines. Also our fast guy Ozgur's HSN was 2 turns out at the end of the day.. Maybe Nano may comment on this needle setting.. Temp. was around 110-115 C..

As mentioned before, we realised that it takes time for engine to heat soak.. It's important to wait it to heat up completely before tuning..

the only problem that a couple of guys here are getting, is that after the engine cools it is very hard to start and bogs bad and once it starts it runs perfect,
I my self have the 07 version and the hsn was alittle lean had to richen it up 3 hours and low 1 hour other than that I really had no problems with the newer carb but with the older carb with out the update screw that I never got it right. but with the os carb I did not even touch the settings prior to installing it I just had to rich the top and richen the bottom and did not have a problem at all ran it all day yesturday and started up every time with no problem..Give it a try see what you think

We realised one more thing, orion glow plug needs much more current than other brands. We also checked needle settings before starting per carb. update insert which was in the manual.

factory settings were a little out of tune and we adjusted per insert and adjusted glow plug driver to max. setting. A little weak powered starter may start other engines but CRF needs a higher speed for starting..

Hi,
can someone give me a good starting setup of the carb for the CRF Cyrul spec on 16% (already have the head shimmed out with only one 0,1 ring) LSN, HSN and spray nozzle?
Orion's settings for the new carb doesn't work fpr me (i think its way to rich)
And also the spray nozzle old spec was a turn out but the new one 1 ???
(with 1 turn out i get it better to work than on 1 out)

Thx

Are you sure you have the new carb? if so the carb insert should be conical vs cup shaped on the old version.

The settings I posted on our website are the settings we use as base settings and they work for us everyday. Obviously you will need to fine tune them but they should be very close. Also these are used along with a good clutch and a pipe that suits the engine.

If you are far off from these I would generally assume that something is not right.

I have the CRF Cyrul spec (with the conical insert)
I'll try again this weekend, and have now used the 47,9 with a fully unscrewed the slide valve stop screw (to get a better measurement)
