I didnt mean it wouldnt work I meant they are different the tm38-85 from the tm40

plug and play indeed its an easy conversion no matter what flatslide you use

good luck!

Hi Christian, if yours does not look like mine then there is a fair chance it may be part of your problem, if you look closely at the hole on the right you can see threads in there but on this 38mm carb there is nothing screwed into it BUT on my 41mm TM38 sitting on my shelf there is a jet screwed into it which would reduce venturi suction at the main and needle jet possibly causing a flat(bog) spot.
Do you have all three holes open on your carb?

Im thinking about at least doing the side vent mods much like the xr650r guys do

It time to let my bike breathe I guess and I could just get another sidepanel or a used one if I dont like it

I think my hrc cam and flatslide could use more juice up top so maybe jetting fatter AND giving it more iar could help

maybe just maybe
I thought about the sidepanel too (the one which acts as filtercover) but decided NOT to do that.
Reason is since you move your leg around a lot on the bike there would be a chance you'd block off the holes which again would cut off airflow, next to that, when riding in open plane you'd might have change in airflow in case of strong side winds..





I'm gonna dyno it next week.. finally

Does all that chopping REALLY make a difference???

I am only asking because I think that any hole in the airbox larger than the cross-section of the intake runners is pointless, as the intake runners can only flow so much air. And with all the chopping done to the airbox, the possibility of getting a gutful of water into the engine is increased.

I could be wrong, but that is how I see it...

wow what a ride

soooooooooo

got it jetted right

my flat spot or bog comes from bad jetting not from missing any circuits or passages etc...

but thanks for the tips.

this was confirmed yesterday

I had one of my best rides to date...I rode 30 miles of beach or so right to where my boat is jajaja

Met up with some friends and talked crap till sunset and more

the rode street home like a madman up to san salvador, ran out of fuel 2 times and used up super secret reserve and made it to the one gas station that was open just in time

flying 90mph down the beach playing with the water and birds and lofting the front wheel over the little dunes on the left was magic...must of looked crazy to the fisherman and kids that were waving at me like nuts while I was doing it but MAN

what a thrill

no pics, just the ride in my memory jajaja

PS. JETTING changes were this

needle clip to richest setting(makes sense since the dual headers flow better and use a bigger main on stock carb) change from middle clip.

mainjet up to a 230 instead of a 220

Didnt check oil temps cause apparently I was hauling ass too much and the thernometer cap flew off into the wind! jajajaja

anywhoo

a ride to remember

christian

94 XR600R throwing parts at it, still wont 'rev'

I bought a 95 with a blown motor. Put a motor in it from a donor bike. Previous owner of the donor motor went through the carb 3 times thinking he had carb issues. He ended up thinking it was electrical. That motors stock besides bore 3 over.

I put that motor in my bike. Cleaned the tank, petcock, new fuel line. Clean the carbs (stock jets), replaced every seal, new air filter (uni), stock exhaust with baffle removed and new gaskets. I've tried 2 different cdi's, 2 different stators, 2 different pulse generators, set the valve clearances. I even went back and readjusted the right exhaust valve just past tdc to make sure decompression lever wasn't interfering. The wiring harness and ignition coil, spark plug (new) off the bike with the blown motor.

Results. Bike idles but dips. I can ride it on on 1/4 throttle and walk through all gears and it pulls great. Start to give more throttle and it "bogs" "hicups" "skips" "pops". The spark plug is black and I see dark smoke when I try to rev it. I've tried everything on the idle screw from all in to 3 out. Seems the same. It will die if I turn the idle screw all the way in.

Any thoughts? Think maybe the timing is off just a tooth or so? Maybe cam chain stretched?

Thanks in advance for taking the time to read this..

I've read a lot of his comments and threads. Simply amazing. I wish I was on the other side of the country! Read your thread too from a few years back when he coached you on the rebuild. Good read!

hell show up in a second

but here are some questions he might ask

what jets are in your carb and what needle setting and are the jets and needle stock

have you done a compression check

verify your timing

check valve clearances

good luck and welcome to the xr6 club!

My Yamaha Warrior ATV did the same thing to me except it was also leaking fuel out of the overflow. Turned out the needle and seat were bad so it was getting too much fuel in the carb.
