hi all . im new to the forum and also just purchased my first yamaha ttr250 2005model . wanted to know is there anywhere i can get a fmf q4 for my bike and also the jets to re-jet the carb . also i went for a little bit of green laning today and the engine was getting very hot any ideas on what i can do to have the bike running a little cooler ?? . any info would be great . thanks
I have two TTRs with these pipes on and no re-jetting was required.
However, if you made changes to your airbox (opening it up in some way) then it may be necessary to adjust the needle clip position or go up a size on the main jet.
Jarrah's advice on possible causes of over heating are good
Thanks for the links to the fmf and jets. Will be getting one very soon . Yes guru Wales is very good for off road Iv got miles and miles of the stuff . And still can't get enuf of it . I'm going to go with the fmf I seen a ttr with one on and can't wait to get one after the sound on it . It was the fmf q4 wasn't to loud and sounded just perfect so I'm going to go with that . Thank for the advice both appreciate it
