I have inspected the engine oil filter and found very little two sections of the filter showed a little metal but not really more than you would expect from a newly broken in bike . The fuel pump continues to run at all times I disconnected the fuel pump removed the plug and checked it for spark: no dice. The 10 amp fuse in the back is fine, I assume that is the one and only fuse on the bike. ' Is it safe to assume that my bike has no spark (and fuel pump runs constantly) because the ECU is toast? I did not check for power from the magneto or check the pulse generator out yet....i guess i just assumed the ecu was junk where can I get the part?,Best to find someone nearby with a D&M kit to test your ECU for communication. If no one is available, your ECU can be sent to Canniboomer to be checked for proper function. If it fails, then he can send a new or possibly a used replacement. Don't forget the Diode update is likely necessary on your bike. ,,,

Apache quad rlx100cc evrything seems ok turning over seems to be not a great earth possibly but main issue is getting no spark i have put in new lead and new plug have checked all wiring starter is...

Check kill switch and lanyard kill switch if it is equipped with one. CDI may be bad. This is very common on small engines. Could also be the coil. My money is on the CDI! good luck.

Clutch pro

5w of oil difference is not the problem but using hypoid oil in the trans case will. Change the fluid and make sure you have the clutch adjusted correctly I believe it is 37mm from clutch cable boss on the block to the point on the top of the clutch pivot arm where the cable attaches. ,,

Need help 450 mx

I am new to the forums and I am currently looking to buy a 2003mx 450 It is street legal with CA plates and he wants 2200 for it. When I go check it out is there anything specific that I should look for? How reliable was the motor in the 03's? I am not sure what other questions to ask. I would appreciate any help. edit: also does $2200.00 seem like a good deal for this bike? Make sure it was street registered before the cut-off date in 2004. For the rest I'd do a little bit of reading on this site on the updates needed. At $2200 it's a good deal. ,

Who to go ingine rebuild

and have done more working on the bike than riding the bike. Unfortunately I'm back in that position again of the bike not running after getting it running last fall then overheated and wouldn't start again. I think that I'm going to spend the money to have someone go through my 450 mx and rebuild and update some of the internals. Was thinking of just bringing the entire bike to someone and that way I know it would be ready to go when I picked it up. The bike is in Boise (would be pretty easy to get it to ATK), but am working in Seattle area during the week right now for a while longer. What are the options on this and who would you recommend? ,Since you are in Idaho I would recommend Blackwidow. They are a site sponser. ,,,

Slow deceleration in neutral

it revs fine but then backs down to idle slowly. Cdsracer mentioned that his cousin's in SoCal also does this.... Is it due to the different dirtbike clutch basket size? Any idears? Something simple maybe?Mine both drop right back down. Sometimes a slight hover at 2200 RPM or so then settles at 2000 RPM (usually only before motor has fully warmed up) ,,,
