A forum for owners of Yamaha TTR250 trail and enduro bikes!

Hi Ivan and welcome to the forum!

Probably best to use 3rd gear else the wheel will lock up.

I guess you are keen to get the TTR going but if it isn't running properly when using the electric start then bump starting will be a lot of effort with the same result. 

As the TTR has been standing for a while there is a good chance the carb may have gummed up - particularly the pilot jet. However it should start and at least tick over on the choke 

Also make sure the air filter is clean and not disintegrating after storage.

If you haven't already done it, run some of the fresh petrol through the carb by undoing the drain screw at the bottom of the float bowl. Use the best fitting screwdriver you have and put on plenty of pressure before trying to undo it else you will round the head. The petrol should run out freely. If it doesn't then there is a problem with the float or in the fuel lines or tap.

Try starting it again after doing this. If it still stalls when opening the throttle you will need to get the carb off to clean out the jets.

Let us know how you get on

The lower the gear, the higher the engine speed for any given road speed you can achieve.. Therefore the rear wheel is more likely to lock up in lower gears. There are a few factors to consider .. If you live on top of a 1 in 3 hill, weigh 18 stone and have a few mates to push, you might get away with first..

As as Brian says sort out the basics first.. You only thing you gain bumping is possibly a better spark as you dont have the current drawn by the starter motor.. I would favour jumping off a car battery rather than puffing myself out and having to push the dam thing back up the hill.

ps If you do jump off a bigger battery dont get carried away and run the starter too long..
