rxl help

i have a 95 polaris rxl 650 (efi). i took it in to the shop and they looked it over.they adjusted the clutch and weight and lubed it up. its still a dog. at full throttle it does about 85 mph, it only has 2900 miles on it. it also uses about a quart of oil per half tank?? can any one give me some advice on what to look at or look for?? this thing should fly, but it doesn't. is the oil consumption about right or is that too much. is there and adjustment i need to make?? any one with any info, PLEASE share it with me.

Re: rxl help

Belt worn?

The only other thing I can think of is maybe plugged fuel filter, or Bad sensor some where and the computer is compensating. I've seen my buddy's do 95 with TWO people on it, so something is definetly up. Did the shop check the computer to see if it was putting out error codes?

Re: rxl help

yeah, they replaced the belts, i checked the comp and no codes, im running injector cleaner through it, de-icer, high octane fuel. i dont think its as simple as adding more weight to the back?? im at a loss here, i have no clue what the problem is. with a 120hp(i think) it should do well over a hundred. my only real concern is it uses alot of oil?? have any suggestions??

Re: rxl help

Ummm...Oil consumption. Check the oil valve arm. The design hasn't changed much over the years, and I just put a new throttle cable on this summer and had to adjust that oil cable myself. I know it's a bitch but take the airbox off and have a look at the timing marks on the arm and pump. On carb sleds they line up at no throttle and then again at wide open throttle. Yours may be set such that it's flowing alot of oil even at low throttle levels.

The other thing to check is all the oil lines and pump seals, vent lines, tank for cracks, maybe you're losing it not burning it. Are you fouling plugs? If not then this may be the case.

You're right about the power, you should be able to get 110 without a problem. My buds will turn the needle all the way around. He's piped and chipped though. But my stock carb 650 got 110 last year soooo.....

are you the original owner? If not did the previous owner mess with the gearing and take it off stock?

Re: rxl help

I agree on gearing stock was likely 20-37 or so. With no codes set your going to have to keep looking. God forbid but you may want to check piston skirts. Also oil pump on these machines inject at 100:1 at an idle and then change to 40:1 at half thottle. This equates to 16 oz of oil per 5 gal of fuel or 1 quart per 10 gal. While you have the butterfly assembly off checking the piston skirts check pump adjustment. There is a hash mark on the pump that should line up with one on the lever with no pull on the thottle lever (at idle), adjust accordingly. If a little rich don't worry about it .. better safe than burned down.

Hoe do you get the code out of it?

Re: rxl help

There's a light somewhere on the edge of the box someplace that flashes out codes.

FYI my buddy had an injector go bad on his 92, and he got a bad bog. I haven't read your post but I know you say it's flooding, I'd start with testing the integrity of the injectors. You may be in a situation that only the dealer can help you with.
