Hard to start
2004 300ec
Is there a shop manual on this bike? Need to get the voltage output for stator. Need to get ohm reading for ingition coil. Spark looks weak. Any help would be appreciated... 2007 HONDA CRF250X CHRISTINI 2004 GASGAS 300EC 1999 SUZUKI MARAUDER 1998 KAWASAKI KDX 220 (SOLD) 1983 HONDA XR200R (SOLD) 1979 YAMAHA DAYTONA SPECIAL 400 (SOLD) 1976 YAMAHA RD400 (SOLD) 1972 YAMAHA XS400 SPECIAL (SOLD) Last edited by TRAILBLAZER808; 08-13-2014 at 01:30 AM.

I got some voltage readings.
For the impluse coil: Red/White wire - ground = 3VAC at idle For the impluse coil: Red/Black wire - ground = 12VAC at idle For the exciter coil: Black/Red wire - Red/White wire = 12.5 ohms For the ignition coil: White/Blue wire - Green wire = .7 ohms For the ignition coil: White/Blue wire - spark plug boot = 19k ohms Can someone verify these readings? Thank you for your help...

Checked reeds they look good.
Put a new carbureator. Checked and cleaned all connections. Compression is 145. Hooked up a used CDI, same problem. Waiting for new Ingition coil and rectifer. I hope thats the problem, a new stator cost $350.00 Why dont GasGas put out a shop manuel like the Japan bikes? Oh, I guess its so the can sell more parts to bike owners like me, that dont have a GasGas mechanic to go to. I hate to say it but Japan bikes get so much more support and they dont break down as much. Last edited by TRAILBLAZER808; 08-18-2014 at 12:01 PM.

Sounds like it needs a new top end, compression test should be giving you at least 170psi.
And I've always found mine to be more reliable than jap stuff..

Here are some threads to read regarding coil/exciter/stator readings:
http://www.gasgasrider.org/forum/sho...ght=spark+plug http://www.gasgasrider.org/forum/sho...hlight=Exciter The search function on this site works pretty well if you only use one word at a time. If you use two words it seems to not care and gets all weird (just like most of us on here).
