I have a 2001 Volusia that's been rejetted (not by me). I've got a uni-filter and slightly drilled original pipes and no pair-valve. Everytime I ride on the expressway at over 75 mph I can only go about 15 miles before the bike starts to bog down and lose power. I'll pull it over to the shoulder and wait for a few minutes, then continue on at about 70 mph but usually look for an exit and take side roads the rest of my trip. This has been happening for about 2 years (and after the rejet). The bike can go all day at any speed under 75 mph.

I'm at a loss at what to look at first. Any ideas other than starting from scratch and re-doing the rejet?

Thanks for any assistance. Steve

you may need to increase the size of your main jet. the main jet handles the throttle when it is wide open. do you know the jet sizes you currently have? it may just be best to do the re-jet from scratch so you know it is right.

i would recommend rejetting to these specs
Aftermarket or stock pipes (baffles or debaffled) & Uni filter or K&N (airbox mounted):
150 or 155 main, 37.5 pilot jet, dyno spring, dyno needle on 3rd notch, mix screw at 2.5 - 3 turns. Adjust idle knob as needed to reach 1100 rpm.

Cory, I'm in Okemos now, just off the Okemos Road exit on 96. I didn't go to State, but my daughter does. I bought a rejet kit a few years ago that Carbon_One used, but I can't remember what the sizes were. It's plain annoying to not be able to ride confortably on the expressway, and I've just put off trying to fix the problem. My nest step is to take it to Groves (that's where I bought it) or Full Throttle. Maybe I'll even attempt to do it myself (plus it will help me convince my wife that I need that new set of wrenches from Sears!)

I'll have to check out the post about the Monroe rally to see if I can make it.

Steve

If you don't get it sorted out by the 16th bring it over to [email protected]'s and we will tear into it. I have most of a jet kit setting here I'll bring along.

Ride Safe,
Rex

... it is possible they went to big on the jets when you had it done ... I noticed this (almost) same problem with my '02 when I rejetted to the Thunder kit and tried bigger jets than what they recomend ... sounds/reads like the other guys are onto the same issue ... though the good news is it sounds like you have the correct pilot jet installed ...

... what's your bike do when you jump on her hard from a stop?? ... and don't say bounce ... lol ...

When the power loss happens, reach down and open the choke up about 1/4 of the way. If you gain engine speed you will know that you are running to the lean side on your main jet. You can also move the e-clip to the 4th position this will give you more fuel also. Might want to check the fuel line leading to the carb, it may be kinked.

Danzig, I tried the choke the last time it was happening and it didn't affect the bike at all.

RevBill, there's never been a problem with acceleration or starting without leaving the choke out for extended periods of time, so I know that most of the rejet is working fine.

I've been so concerned about the problems in the highway that I've rarely gone on one for the past 3 years, so I'll go over the fuel lines and hoses again with the tank off and see if there's a kink or something's not quite right. I'm going to print out the pages from the Rusks website and take a look at the carb and see what's going on.

I appreciate all the ideas.

Sounds like a vent problem, not enough air entering the fuel tank to compensate for gas leaving. Try the Freeway run with your Gas cap loose.
Oh, be sure the tank's not full.
