Hey all, just looking for honest opinions. I recently purchased a 1989 TRX250R. It has a K&N Filter & Outerwear Precharger, Keihin 39mm PWK Carb, Boyesen RAD Valve, Pro Design Cool Head, PTR "ELIMINATOR" Pipe and Quiet Fat Boy 2 Silencer. I am 6'5 tall and weigh about 255 lbs. Do you think I would be good to go to ride the Oregon dunes on this bike without blowing it up? I only worry because of my weight and the resistance of the sand on the paddles. I don't want to blow this bike if a t all possible. Please let me know your thought when you have time. Thanks, Pete

As long as it is jetted properly, ride it like as much as you like.

I agree with Huntertools. Make sure that it is jetted properly before you go. If you are unsure, make is very rich and change out the jets once you get there. You should take along main jets 150-185 with you. Then just change them as needed.

You should be fine just make sure it's jetted good, what paddle are you going to run?

Skeans1 - I have a set of 9 paddle haulers and a set of 8 paddle Sand Stars. I am thinking the 9 paddle haulers would be to much hook up on the sand.

rablack21 - Thanks for the advice. I am not sure what you meant when you said "If you are unsure, make is very rich". Are you saying it should be rich or not? Thanks bud.

He meant jet it on the rich side to be safe and jet down as needed

Since my carb is a Duncan Racing, pre-jetted Keihin 39mm PWK Carb, I wonder if they have a jetting / elevation chart? Anyone know?

Cheap easy way to get some main jets is from Eddie Sanders with his jet wrench. Paddle 9 might be do able or could hook too much it's personal preference I like bite but I'm on the other end of the scale for weight. Another good option would be some Sand skate 2's if you can find a set they hook good as well as have some slip.

Take the float bowl off & see what main & pilot you have first before you get more jets. I weigh 180 & my bike has a similar setup with a 185 main jet. If you get jets stick to the upper 170's & 180's for the mains & 45-52 for the pilot, that range should get you dialed in out there.

You don't need to worry about your weight. I am 6'2" and 280lbs and I ride my 310 hard in the dunes. I run 9 paddle haulers and love them. I agree with the other fellas here that you should #1 figure out how your carb is jetted and #2 start off rich and work your way down. Good luck and happy duning.

I'm fat to lol I'd prefer the haulers over the Itp sand stars. The sand stars are a lot heavier than the haulers
