Good GasGas 2 stroke mechanic near Portland Or
I need to find a good mechanic for my 2008 EC300. It used to run perfect until I changed the ignition to the EC3 to run my Trail Tech HID lights. After that it has a horrible blubber in the midrange. Trail Tech has gone through it and they say every thing is good. I order the LTR jet kit from GOFasters which really wasn't a kit just a DDK needle and the 2 jets I all ready had. That made it worse. I have jetted it all over the place and nothing helps. I give up and if I cant get someone to fix it it's going up for sale. Any help would be appreciated.

Sounds like you need to just go riding with a couple of guys who know jetting and take a handful of brass, including needles. I'll volunteer if we can coordinate a place to meet.

I am up for going riding anytime. I really don't think it is a jetting issue but I could be wrong.

I know a good mechanic in Portland
Lineman, BOSS or Bozarth Offroad Specialty Service is in southeast Portland. Don't have the number-need to 411 it. Rick is racer and has been wrenching on huskys and ktms since the mid 80s. He knows ohlins suspension etc..He is a top Husaberg dealer, straight out of the shop behind his house. He is real meticulous and fair and will tackle most things.
The settings on my 250 are: needle ltr or the proper brass one, pilot 43, main-180 ,mixture screw-1.5 out. Yours should be vary similar. Oh, and I think needle is in middle. Obviously you are running good gas with proper ratio. is the float parallel with the carb body when upside down? Have you looked at the intake boot or overtightened the clamps on the boot-seen it done. Air leaks downstream from the carb will do weird stuff. Kill switch?(I'm just thinking outloud). Sounds like if its not fuel dilivery it's something shorting out or not getting enough kv to the plug. I think you may be right in your assumption with the electrical. Rick's shop is at 237 SE 83rd ave Portland Or |

Float level is good I have tried many different option of jetting. What does over tight clamps on carb boot do?

Sounds like the timing is off. We had this happen last year when gasgasman & myself put a new stator in the Perry Mountain 24 hour race bike.

I re-jetted it with DDK needle middle position 178 main and 40 Pilot. I also pulled the power valve cover and sprayed some cleaner in there. I took it out for a ride and it pulls real well. I am only a half turn out on the fuel screw. The farther I go out on the screw it starts to blubber. It is not perfect but getting closer. I still thinks it is weird that it ran so perfect before the ignition swap. I was running a 35 pilot 178 main with stock needle before. This is the same jetting Roscoe is running and it ran great before ignition swap.

Leave the needle clip @ 3 position (middle). Then go after the pilot jet to get it correct first. You should try to be in the 1 to 2 turns out range. This allows you adjustment flexibility in the future for temp/humidity changes. Approx. same air/fuel mixture, I would try the 42 pilot. Current setting: 1/2 turn out air screw @ 40 pilot. New setting: 1 turn out air screw @ 42 pilot. Note: pilot jet influences the 0 to 1/4 throttle range. AFTER the pilot jet is good... Then I would investigate the needle clip position. The needle clip position influences a broad range from 1/8 to 1/2 throttle. If too rich, more clip up 1 notch (2nd position). If too lean, more clip down 1 notch (4th position).
