Faster Blaster - The Long Lean Run From The Border

The response - No, I did not do it. Jason was not able to travel to Glamis with us last Thanksgiving so he never got around to bugging me about making his bike faster. I'm wondering if he's going to call me soon though since Easter is coming up fast.

The last time we were there together he melted down a piston while cruising back from Mexico. If you've ever done the ride to Mexico from Glamis you know it's a long, flat boring ride if you take the dirt road. It requires cruising at (on my bike) about 7000 RPM for about 25 miles. You have to be jetted right for that kind of riding. What changed on the way back from Mexico was the speed at which we were traveling.

On the way to Mexico we were going about 6500 - 6800 RPM in 6th gear. My motor was running about 1170 degrees (f). On the way back we stepped it up a bit. I was taching about 7300 @ about 1210 degrees. Since Jason was cruising beside me I think the additional speed necessitated the installation of a larger main jet in his Blasters carburetor.

To make things worse, my brothers (Bill) motor went lean while towing the dead Blaster (burned the exhaust side of the piston away just enough to prevent the motor from running). Since we also had a Jeep with us on that ride, it towed his TRX while I towed the Blaster. Screw the dunes (at that point). I went down the highway at 7500 RPM in 6th and under the additional load of the Blaster and its passenger actually made my TRX run a few degrees cooler since the throttle was opened that much further.

Sorry to hear about your mechanical problems during your Glamis trip. Jason'll be back around soon, looking for some Blaster "Easter Eggs"--just let us all know how it works. We learn an awful lot through practicing the art of just listening. Those LT80 racers that are sandpapering the insides of the stock plastic are fully 33% (that's ONE THIRD) lighter than stock overall. They are into acid dipping "non-critical" (?) parts to save weight. They use glass fish tanks, garage sale stuff, to dip the parts in. When a part has a threaded hole, they can (and do) coat it on that spot, to protect it from the acid bath. They drill lightening holes in things and then salve them in with plastic filler and re-paint. The idea being to hide it and plastic filler is lighter than steel.

Mechanical problems I can deal with. Though a little tougher to repair out in the middle of the desert - certainly ot impossible. I know many people who have wrecked a top end (leanout - seizure) driving the road to Mexico. Since there's so much less drag on the motor, and you're not using paddles out there - a rejet is required. The throttle position while cruising at 7000 on a hard pack road is very different than the same RPM cruising on sand with paddles. This difference is enough to melt down many a motor. A couple (or more) jet sizes up on the main will prevent it from happening.

I like the idea of lighter parts. However since I'm not a professional I haven't gone to those extremes. I like the idea of a stock looking bike though. I wouldn't cut the fenders or make it look any other way. That's just a preference though. I hate the look of the larger fuel tank I put on my TRX, but I made that exception because I hate more to run out of gas. Additionally I added the hood from an 89 TRX to get the additional headlight - I like to go fast at night too. The other thing I think of that's heavier (and quite a bit so) than stock is the High-Flight Desert seat I have. My knees used to get so stiff after riding that I started to hate to get on the thing for long rides. I added the seat to let my legs stretch out. It helps a lot. I messed up my knees when I was a younger riding and racing motorcycles.
