First I would like to thank all that helped with the rev limiter questions. I set my timing up as far as it will go and that made a little difference. I still have some problems though. The bike runs good when the temperature is 50* out, but really runs bad (the cutting out thing as before) at 75 -up. Is this a jetting problem? For those that did not see my other postings my bike is a 95 Targa LX with a 70cc kit. The 15mm Amal has a #45 main jet. I raised the needle to both mid and hi grooves, top groove works best. Plug is a NGK #-7 and is a dark brownish-gray, oil is still rich. On warm days it runs okay for the first few miles and then starts to cut out AT TIMES after 7 or 8 miles. It does not cut out all the time, it's more of a in and out kind of thing. On cool days it runs very well and only cuts out slightly after 12 or more miles. What do you all think? I really need to get this fixed, but I could sure use some suggestions. Ride Safe...Butch
