Just got myself a TTR, has a staintune, snorkel taken off airbox, header pipe restrictor has been chopped off, is there any other ways i can make it quicker for cheap, i just want that extra umph
First thing to do is check that what you have at the moment is good i.e. air filter clean and properly oiled, correct spark plug fitted and that it is clean and properly gapped (check the colour whilst it's out), valve clearances, it has clean oil and filter (doesn't make it go better but lasts longer!).
Some hints and tips to "uncorking" here but, as Pete suggests, more ceecees is the way to go for more power.
