Aftermarket Tfs flamearrestor on 1999 ts640

07-30-2008, 03:04 AM

I purchased a 1999 Ts640 2 years ago and upon reading all the information about best performance bang for the dollar I decided to get a Jetinetics TFS tall flame arrestor per reading Group-K TS 650 performance mods. I am overall happy with the top speed (49-50 mph) but would like to improve the accelleration and throttle response (holeshot). Group-K test results showed a good improvement in both accelleration and throttle response with this flame arrestor. I see that the stock carb only has a low speed adjustment and no high speed adjustment. The stock jet sizes are (low speed jet #70 & main jet #135). Do I need to replace both jets? or can I get by with a low speed jet change and adjustment?

Thank you
