Will do. Not exasperated with it, it is a low mileage 14 year old bike, only 1.5k avg miles a year, which means it didn't get used much, I put 8k miles on my first bike first year I had it.

And I got the bike for a great price. 2500 for the bike, 300 for a set of pull off wheels with new tires. Even if I had to rebuild the engine it'd be cheaper than all the other bikes I found.

And barely any rust really, just a few small spots.

I'll check slide tonight, won't be able to do sea foam until next week though. I'll drain the tank and fill with fresh gas. Suggest no ethanol? After I run that tank through I'll take it in for servicing, or should I do that first?

Also, what issues does too much oil cause?

Thanks



You won't need to worry about rebuilding the motor. They're noisy bikes as far as motor noise goes, but they're about as rugged as a hammer.
Drain the tank at the petcock under the tank, and set the petcock on reserve when you do it. Put a piece of 5/16 on the bib on the petcock after removing the line there, and dump it into a container.

If your checking the oil with the bike leaning on the side stand, it'll probably show over full. To check it, the bike should be run until it's at operating temp(ridden for 20 minutes or so). Allowed to sit for a few minutes, and the bike needs to be upright when checking it.

Ethanol tends to cause issues with heat related carb puke more troublesome. It shouldn't make any difference for a tank or so.

Sounds like the main jet may be gunked up. Beyond half throttle, the other carb circuits shut down and the main jet does all the heavy lifting, which would explain the condition you described. May even be a little water in the float bowl; it wouldn't hurt to drain the float bowl. If you want to be certain, collect the gas from the float bowl in a clear plastic bottle to see if there's any water. It will be pretty obvious, like salad dressing.

Like skwearpeg said, best to drain the tank and refill with fresh gas. 16 oz. of Seafoam is a lot, most people only use a couple oz. per tank, but for a full system clean, or a "shock treatment" as it's sometimes called, it couldn't hurt. Also, the bike may smoke a little from that much Seafoam, but don't worry, it *will* clean everything out. Don't change the oil until *after* you run the Seafoam.

As for the oil level, make sure you're checking it properly. R*s have a semi-dry sump, so there's a funky procedure for checking the oil level. The bike is supposed to be fully warmed up and you have to stop the bike, do *not* blip the throttle or rev the motor, let it idle for 15 seconds, then turn off the motor, level the bike, i.e. off the side stand, and check. But even then it can be a bit of a crap shoot to get an accurate reading.

If you have read any posts on here about checking the oil then you already know it's a crap shoot. You could check it 5 times and get 5 different readings. The only way to know for sure is to do an oil change with 4 quarts. These bikes typically use no oil and leak even less. Use a good synthetic 4-stroke motorcycle oil, follow the oil changing guidelines in the tech section, and forget about it till it's time for the next oil change. Who knows how long the oil in it now has been there. If the PO wasn't forthright about other things, it's best not to take his word on anything he told you. These bikes are really tough, and will take a lot of abuse. Once you get it dialed in you'll have a very reliable bike that will give you years of trouble free service with just a minimum of preventive maintenance.

Do what SKWEARpeg says....he helped me out quite a bit a few weeks ago on my carb.

For sure check the diaphram and drain the old fuel. You may have gunk in the float bowl which is impeding the flow of fuel. Once you get good fuel and have run the seafoam through it, if it still has issues check your plugs to see what color they are. If they are black it's running too rich, if they are white likely it's too lean. That's when you verify what jets you have in it. Maybe the PO couldn't get it to run right or just let it sit.

Ok. Slide is moving.

I took a video, but no idea how to upload.

Anyone willing to send me a pm with a cell# I can send this to to be looked at?

+1 on the main jet being gummed up.

Are you seeing fuel come up around the needle in the throat, when you roll the throttle? Is there fuel squirting out of the brass access nozzle in the throat(the horizontal one)?

Have you drained the bowl and tank and replaced the gas yet?
Have you done any Seafoam yet?

I am seeing unsteady fuel flow from the needle.

No, haven't been able to drain everything yet, had a fam emergency and had to drill out one of the bolts holding on the cleaner
