Top Speed 47mph

Today i was out doing task and wanted to see the top speed of my rebel, i was surprised it only hit 47mhp. It was on a flat road with no hills. From all the post and information i seen it's at least hit 70mph to 85mph could something be wrong with my engine?
I'm 220lbs

:::Update::
I just checked out the filter and it had black stuff in it from the tank. It looks like it did its job but would that have stop it from going over 47mph?
How to clean this filter out or do i need to buy a new one?
Also could any of that rust got into the engine and damaged it?

compressed air may blow out the filter contamination..

Yes a restricted filter could cause fuel starvation resulting in poor speed
unlikely any engine damage could be done by rust other than clogging carburetor fuel passages..
With any filter that shouldn't happen.. install a new one keep old as spare..

I prefer a big ugly paper filter over sintered metal filters due to the larger filter area..

mine is very similar filter off brand from the idiot national chain auto parts store..
Wix is a good brand I often use their oil and diesel filters
You will find turning the petcock at an angle will keep hose from kinking

Now for the tank.. A good citric acid internal cleaning using a hand full of Square nuts or DG Decomposed granite pebbles to agitate/scrape the rust..
Than seal inside with Caswell Gas Tank sealer.. or hot tanked which takes off paint too.

To be honest I ran over 2 years having to stop every month or so to blow out filter on road side due to severely rusted tank.. pita when your in fast lane..

the little cone-shaped filters are disposable dirt-bike filters, I buy several at a time and keep 1 in the tool-box on board the bike.

loosening and turing the petcock 10-20 degees outboard does indeed work for making the filters fit better in-line.

I do have a question about putting grist in the tank to remove rust (nuts/bolts/rocks/decomposed-granite, 5 year old fruitcake, etc...), how do you get it back out? Maybe my tank is peculiar, there is a collar at the fill port so turning it upside down will only trap the stuff, likewise the petcock port has a collar extending into the tank to allow sediment to settle at the bottom-back and not get sucked in when you hit really-empty so shaking it rightside up won't work either, and the 'hump' down the middle that allows the tank to sit around the frame is so close to the bottom of the tank fill collar I can't even see down into either side to see if it is rusted or not, much less reach any kind of tool or vacuum hose to suck out the grist.
I had some particulate matter in my tank, and just flushed it with a garden hose, then a fair amount of work with compressed air and a hair dryer to make sure it was bone dry. Not ready to try dropping stuff in there that I can't imagine how to get back out again?!

water and compressed air.. dry in 100 degree oven or summer sun...

1938-40 Coleman 35,000 Btu handy gas plant I restored has 1" filler tube that extends 4" into 3 gallon tank... had to use Square nuts so magnet could be used to remove them.. the Rebel inner tank lip isn't that great a challenge.



I've used the grit or nuts on several kerosene and gas lamps with great success

when I cleaned the rust in my tank, I used a small rubber drain plug to fit tightly inside and just a little sticking over the filler hole, and i screwed a small piece of chain about 2' long to the bottom side of the drain plug. I filled the tank with muratic acid, and installed the drain plug with chain attached, then shook the everlasting stuff out of it, and let it sit for an hours with the acid still in it, then gave it another shake, roll, twist, and any other type of movement to get the chain everywhere it could possible go. and that worked great for me, after i rinsed it out several times with water, and then a final wash of acetone, i coated the tank with red-coat brand sealer.

this is the inline filter I use, basically because it's very short, and I like the color of it on my bike.
