2001 Yamaha TTR90 hard to start cold

I have a 2001 Yamaha TTR90 that used to start on the first kick. It sat for 4 years. I cleaned the tank; took the carb apart, soaked in Berrymans, cleaned w compressed air; new plug; cleaned air filter; adjusted air and idle. Now, once started it runs great, but it takes forever to get it started! It'll kick over first time for about 4 seconds then die abruptly. Then just keep kicking for about 10 minutes til it finally catches. Any ideas? Thanks!

My guess would be that you have dried out seals/gaskets taking away from the overall compression. This will either get better with use as everything lubes up or you will have to replace all that are leaking.

    Could this still be true even though I used fogging oil in the cylinder before turning it over initially?

Hard to start cold


Check the choke functions correctly and that the idle mixture is correct. If that fails strip and clean the carburettor.

Bike sat up for 3 or 4 years. recently cleaned the carb, changed the plug and oil and bike started. Tried starting it recently and it wont. Seem to be backfiring sometimes when kicking it over.


clean plug .. although new plug if old fuel or unbalanced carb it may quickly foul. if this works you may need help to work out whats causing plug to foul.

4 strokes are notorious for having a hard time with hot start. use your hot start choke every time, change your plug, and clean your air filter. if you are still having a problem check your intake valve clearance. .10 to .15 mm is the tolerance on the intake side.
