TM38 settings (with 38mm bore)

I hadn't looked for a while so I pulled the slide out to get the settings for you and found I had been dusted via the filter box somehow, need to investigate further but this donk is coming out for a new crank anyway, this is the mid eighties crank I put in to get to an ADV gathering last August that successfully knocked its way for 4000klms to Cape York and several rides since, bloody tuff engines. Answers below in orange.

ok here are my questions:

what needle clip are you running? 6FJ40 needle with clip at top groove, throttle response would be better at 2nd or 3rd but I use this for trials type riding and like it soft.
what exhaust and or headers are you running? Stock headers and muffler without baffle.

do you have stock cam? Stock cam.

Im running a 220main but that is because the hrc cam needs less fuel at wot and mid...I need to put the 230 back in and play with the needle. 12.5 Pilot and 230 Main and the Carb bore is 38mm, air screw 2 turns out.

I had a flat spot midrange that just developed(jetting takes a while) jajaja
I had a killer flat spot on my 02 650L with the TM38 flatslide but it has been bored to 41mm, I found the needle clip at the top so I moved it down to the middle and changed from a 12.5 pilot to a 20 pilot, it has a 230 main, I figure I could go back to a 12.5 pilot now but it was terrible until warmed up the way it was.

thanks

oil cooler is next for me
Mine is sitting on the bike but not connected yet.

thanks so much for the help
My pleasure.

christian

I got mine from Ballards (not the cheapest), sent me one that was too short, they wanted me to pay to send it back before they sent the new one down !
Very worth while upgrade. I tried a few pads and settled with SBS. Roost.
Hey mate, thanks for the info (you too, deejay_xr).

Because I didn't want to buy the wrong size hose and bolts I was just going to do what deejay_xr suggested and buy my own stuff so that I can size it correctly myself. But then after reading what RoostMaster said about the need for it to be ADR-compliant etc (whatever that stupid standard they've made up for in Australia) I thought I would just contact the company to see.

A few emails later and we have found that the newer hose and bolts should be identical to older ones so should bolt up fine, which was confirmed by elsalvadorklr too (thanks!).

The company I am considering buying through, Venhill, seems to be pretty well know in this scene and are DOT/ADR/TUV approved, like the ones Ballards sells which i believe are Goodridge. I had only heard of Galfer before as that what made Dad runs on his BMW's.

Anyway, I'll let you all know if I do grab them and see if it makes much difference.

Cheers,

John

EDIT: Just found these guys too: http://helperformance.com.au/store/p...oducts_id=8431 for $54 AUD it seems like a pretty good price. Might check Ballards to see what there prices are too.

update

brake bleed a complete success and I have better lever feel...however I still need new pads, doh!

bad news is change in needle clip has brought back the famous BOG flatspot.

uuuh

so I had it at second from bottom and went to 3rd clip it made it worse so apparently my bog there(if im not brain farting here) is from not enough fuel not the other way around

I will reverse this tomorrow and go 2 clips the other way...

thats pretty much how my jetting goes nowadays, i change this way...

if worse I go 2 changes the other way, if better I leave it or go back one

screw plug chops

jajjajaja

peace and thanks to all for the help especially kenno

I have a non bored tm38...not 41 like xrsonly sells

my needle is leanest at 6fj41

Air jet removed?

I have 3 TM38 85 carbs, one is 38mm and two are 41mm and they all have the 6FJ40 needles, the 38mm carb has a Q-2 needle/main jet nozzle.
Do you still have the air jet fitted? The two carbs that are running good have them removed but the carb on the shelf still has the air jet fitted but I don't know how it runs.

No air jet fitted to the 38mm TM38 and the bike suffers no flat spots

I had the sudco FCR41 on my XR I had it jetted rich, but every single time, bring it to tdc just a little past one kick of all 140lbs of me and it ALWAYS fired off and never needed the choke. Had instant wheelie torque right off idle. The snap everyone talks about with the fcr carbs is exactly right, once you get it right it is awesome. I had to swap the AP to a crf style to shorten the pump duration (not adjustable) but man that thing ran gooood....

Just sayin if yall are running the stock carb on these beasts time to step it up.

I bought the TM40 but have not started the bike jet. What's the story with the air-jet? I have a pilot 30 and main 140, 100mm piston...

could you show pics of the top of the airbox? what you did to cut it up?

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
