Missing compression my man, fuel,air spark,good bbq.No worries

Right, but what has the OP done to his bike to mess with his bike's compression?

fuel air compression/ timing

If no comp your a wet fart

go back to basics . you need intake /exhuast. don't be poring raw gas on rare steak. God only knows, ets help him. missing compression and why I have seen people line up ring end gaps on major thust faces and wonder why oil is blowing out the ass end

Brendan.c check out rmdra.ca

So today after work I got back on it! I tried checking everything listed. I didnt make any mods or do anything to mess with my timing, so that should all be fine.

I started by checking the spark, I pulled the old plug and replaced it with a fresh one, held it against some metal and I do have spark.

I removed my new air filter and checked to make sure I had nothing behind it blocking the intake and as I suspected, it was clear.

I then checked all fuel lines coming from new tank. All lines looked and felt good but to be sure, I unplugged the line from the bottom of the on/off/res. valve and then opened it, fuel went everywhere. SO all lines are free flowing.

I then drained the fuel out of my tank and put about a gallon of fresh gas in. STILL NO LUCK STARTING!!!

I removed th eexhaust and checked to make sure nothing was blocking that, all clear.

I then tried unplugging the new headlight thinking it may be drawing too much power. Still nothing.

After trying and trying and tryign and th ebike just cranking and cran king, I finally got somethign. The bike backfired!!!

THAT WAS THE EXTENT OF IT!!! MY BIKE STILL WONT START!!!

ANYTHING????????????

Thanks, MAXX

Give the air cleaner a shot of starting fluid. If it starts for a few seconds and then dies, it means you let it sit too long and will need to clean the carb jets.
