Never can have too much power!!! If ones good two MUST be better - Right?
The one crank/rod set up were seized as one and had to be replaced. Just put a new stock setup in.

Edelbrock question.

This is for the XR250 eddie, but it's pretty much the same carb.

Anyway, let the XR sit for a few months and failed to drain the carb. So went to clean out the bowl and realized the gas ate away at the black mesh-spongy screen in the bottom of the carb. I just took it out, and reinstalled everything without it. Bike starts fine, but am curious what exactly that mesh screen is for, and should I look at getting another one?
My edumacted guess is that it screens/traps/catches particles in the fuel, and stops them from circulating in the bowl.

Any insight?

OK upon your guys suggestion a few pages back I tore the carb off my bike to clean it. Turns out the needles are clean, but its using the stock needle sizes with a pipe on it! 125 main and 65s is stock right? Damn previous owner told me the bike was jetted! No idea why he ran the bike like this...


The bike stalls every once in a while on idle (scary for me as a new kick starter in traffic ) and backfires/pops when I let off the gas. The mods on it are a Uni filter and a FMF titanium pipe. Also say if I am in 3rd and run it out and shift into 4th, as soon as I peg the gas there is a second or two of hesitation. At first I assumed the bike was running quite rich but it has to be lean has hell correct? When cold the bike will die if I give it full choke as well.

I am going to check the plug soon too so I can get an idea if it was lean or rich...

My altitude is near sea level (under 1000ft) and temps are around 70-90f during the day (Bay Area CA.) I am thinking 170 or 175 main and 68s idle. Does this sound good with a pipe and filter? Where is a good place to order the jets? I assume the bike will run better after, but will it have more power too? I am not sure what is "normal" power wise. Should this bike wheelie if I grab a lot of throttle in 1st? I have sumo wheels and a 15t front sprocket and it does not seem like that is possible with my 220lbs ass on the bike as it is now.

My plan while I have the carb off is to check the valves and other tender loving care to my new to me BRP.

EDIT: Are there any other parts I need to order to "uncork" the carb?

Jetting should be 175 main,b53e needle in 3rd groove from the top,68s pilot jet.Make sure it has the correct intake manifold-the oem manifold had a restriction in it.Take a hole saw and saw out the middle of the baffle in the pipe.A aftermarkit pipe will help.If you run 1 of those airbox screen kits from xr's only you can jet up to 178.Also try a 1996 xr400 cdi box.

I'm in Elk Grove and run a 165 main and 68s, but I always head for higher ground when riding the thumpers, never really ride around the low elevations.

Good uncork article:

Being a California bike you might have the smog stuff still on it, eliminate that junk too.

Oddly enough the smog pump is gone already. So at least that is done. I have ordered the parts from service honda. I am quite excited to see this claimed 27% increase in power . I was pretty happy with the bikes power as is!

It just ran like poop. I am enjoying so far how easy this bike has been to work on. This is the first time I have ever taken a carb apart. Does not seem that bad... We shall see when its put back together. HAHA.

Uncork the Pork

Been working on my new XR650R. Good news is the bike was literally brand new (just 56 miles on an '03). Bad news is it never got ridden. So, it needed a little TLC.



Pulled the gas tank off. Unfortunately it had gas - or what used to be gas . It'd turned itself into low grade black tar heroin. No saving the petcock. $50.


Carb definitely needed love. I got nervous seeing as how the petcock was beyond repair. I got ideas. Actually, aside from another rock of black tar it wasn't too bad. Well, I had to Easy-out the Pilot and replace the float valve. Of course I upped the main & pilot and needle per the official "uncorking" steps. She's good as new.


While you got the carb off, gee whiz $10 will make a difference.


While she's apart, might as well yank the smog pump off this virgin.


What goes in must come out. OK, perhaps this is considered "Fong Ho" by the purists, but it sounds bitchen - just ask the neighbors two blocks away.


Hey, where's this supposed to go?



Got a little more fine-tuning to do, then I'm planning a royal flogging. Been riding an XR650L, so really looking forward to this. Normally ride a CRF450R

Ok now, how in the heck did you do that? I don't even see blinkers for the light inspection.

So what the hell. I took the top off the carb to spray some carb cleaner down the top. When I went to button it back up the damn gasket is now too large to fit.


Take a look at this picture: http://i.imgur.com/sSy8H.jpg

I have the gasket in the freezer in the hopes it will fit better when cold, but I doubt it.

EDIT: MEH Gasket kit ordered. Holy crap 25 dollars shipped. Is there any place more reasonable than servicehonda?

Medisyn,
Put that gasket in the sun, then in freezer - it'll be fine. A lick of grease between your fingers before you mount it will do the rest.

+ Rob also,
I'm just asking, and "Duh!!!" is also an answer - the two plastic pop-out plugs in the airfilter-housing are removed already? You'll find them in the rh-top when you take the rh-plastic off, or rather you should find two large holes there. I'm asking because you still have most corking stuff on it by the looks of it, and then a bigger main jet won't do the trick if it can't get air.


Edit: U2 should also remove the small springloaded choke flap mounted in the choke baffle: flap, spring, screw, the lot goes. You may want to buy a fixed-mounted substitute, XRsOnly have these, but you need them only in very cold climates I think, mine worked fine without. And, whilst you're at it, set the floatlevel to 19mm (+1mm), this prevents pissing fuel when parked on the sidestand.
You'll need to do a lot more than this though, google "xr650r whalesnot" and see what comes up LOL

Willing to sell the seized one for CHEAP? I don't actually need the crank, just the counter-balance drive gear.

1. Very interesting. Definitely didn't remove plugs. That's what the instructions meant by remove rubber & 'plastic.' I took out the snorkel & of course the 2 hoses on top (and smog pump).

2. I know what you're talking about, but didn't know to remove it. XR's Only is less than an hour from my house. Almost went there Saturday, but it was like walking on the sun outside.

3. OkeeDoke on the float, and there was a tad of dribble, but it seemed to go away, so it was on a "monitor" status.

4. Do tell... Will Google "xr650r whalesnot." Actually I wanted to do the Borynack stuff right out of the gate too, but can't find it anymore.

Thanks for the tips.

Thought that might get your attention. Seriously though, all that stuff will be back on before I go down the street. I'll make sure it 100% conforms. I've had it over a month and haven't even ridden it yet as I want it to be all right.

Must have an inside line? I'm selling my XRR right now because I don't have time to jump through all the hoops for a plate and it's just sitting there collecting dust.

Whalesnot refers to whatever Honda put in the forks.

You did? Put them back, that stuff's meant to be there, worse, your engine will inhale unfiltered air through the now-open holes. So btw, the 1 hose is the breather, the other a cap on an unused hole, to seal it - sure you had 2 hoses?
Anyway, the 2 'plugs' to be removed: 1 is plastic (the most-forward one), the other maybe too or rubber, can't remember which shoulder I chucked them over- but they must both come out. What you're left with is two rather large holes (only separated by a narrow pillar I seem to remember) through which the engine draws air from under the seat.

Edit: PM me with an email-addy so I can send you loadsa porn, boobs, viagra etc... oh, sorry wrong forum :) I've got the Borynack fork-file as a Word-doc saved, just under 700Meg. If you've got an Inbox large enough not to reject it I could send it to you. Mind pls, coming Wednesday I go ride, will be back Tuesday, so don't fret if you don't get it instantly.
Edit2: never mind, it's under 700KB, so it'll go anywhere.
