[tecatesr330]

where to start? ok i went riding sunday put gas in the tecate from the same can i always use.(the tecate only gas can).and im not sure if it was mixed or not still not sure but i almost all the time mix it at the pump.i know .any way after i poured in the gas i rode for about 1 1/2-2 hours.the bike ran really good. and thats when it happened.the bike just died.i kicked it over to make sure it was not locked up.even though it was a little hard to kick it started.so i shut it off and went home.didnt take it apart yet but worst case need rod bearings and piston available from cwr.but while the cylinder is off should i get it ported?what dome should i use?i beleive i have a 25cc because i told corey i wanted to be able to run pump gas even though i run most of the time 104octane cam2. i can get a 23cc or 21cc i have a cool head with changable domes.and how will this stuff hurt or help.it is a sprock racing 330 long rod w/full fmf.and 39tooth rear sprocket and im not sure if i should go to a 40 41 or 42 tooth.if any body has any info please dont hold back.any info is better then none.i will take off cylinder tommorrow and let you guys know what i find thanks guys.

What do you mean "it just died"? Like lock up the rear wheels died or like ran out of gas died? It started so thats a good sign, it won't do that with a hole in the piston or missing the piston skirt. First thing, check compression. If its good, I would point fingers at the electical. Tecate's original electical sucks.

As far as what you should do...
Yes port it, the big bore gives you more torque but not much in the way of power, porting will wake it up.

Leave the head alone, to much compression and your playing with reliability. I am guessing you have one of Corey's billet heads. Those are nice!

Take the FMF out to your driveway and run over it several times with the biggest truck you can find. A stock head pipe will run better. Really! Look up Rockhound motorsports on EBay, I know he has a couple of DG pipes. Ideally you would go with a custom big bore pipe but that runs some large coins.

I am a dune rider that loves to climb. I run 13/46 gearing. Mikey (Rockhound Motor sports) runs 13/48 on an ILR330 Tecate. PBI has the templates but you have to order them through you local dealer because PBI only wholesales.
