Jetting for the coast

[honda250r]

I might be going to the dunes on the coast in a month and i was wondering what jets i should get for my trx250r to rejet it for the coast i Currently run a 155 main and a 48 slow jet my altitude here is about 3,600 ft so let me know what you guys think

Thats going to be tough to tell but, I'd take mains from 160 to about 168 and a 50 and 52 pilot with you and tune when you get there

i run a 165 main at sea level, and i havnt fouled a plug in 8 rides. Since your going down in altitude, your jetting will be leaner. Id just drop a jet size or two to be safe!!

Ahhh. Wrong answer. When you go down in altitude you have more air, needing larger jets. If you drop a size or two, you better bring a new piston cause yours will have a nice new hole in it in about 20 min.
