TE/TC TE300 passes the test

We rode an event yesterday that is the toughest local 1 day fun/extreme ride checked in at 0900 signed out at 1650. The new bike got some new scratches and my new gear got some tears.... but we made it through all the AA stuff and finished, this was the toughest of these yet but the skill level of entries has increased we had 41 from 105 (way overbooked)finish this year. I would call this years event relentless. Every time you would hit a flowing trail you would come around a corner and be confronted with next gnarly steep climb or rock infested wash. The bike worked great with minor exceptions, rear sag is to low/deep as I mentioned...as far as the front spring ...for now I will only change the rear spring, the front was working great. My carburation or carbby needs some adjustment I got between 10-15 mpg... ran out of gas near the end of the second section, after the first section put about 2 gallons in and that was "only" a 35 mile section, the second after lunch section was about 40 miles, I will pull the carb and check float level, I all ready rejetted by the book setting for altitude and temp to the next leanest setting. One of the organizers of this event is mr 300 and has ISDE and many other years on KTM300s, he will send me his data, I fully trust him we ride the same stuff.
Important Also anyone know the proper index of the carb on these 300 motors, the manifold has a molded in mark but when you align the carb to this mark it looks suspiciously off level, the bowl points towards the chain.

There was a good amount of industry/pro rider/legend rider participation and swag as usual.

Sounds like an interesting time in many ways and you have something to build on for the next race ... 15 MPG sounds awfully low and scratches on my bike and rips in my gear, are SOP ...

I ran out of gas at 42 miles with stock jetting on my 250. Changed my jetting and had a half tank at 30 miles.

I think shes leaking from the float bowl like Kelly and I mentioned as well I will pull the carbby. Tim do you know about the molded in mark on the manifold? It looks like a proper carb alignment mark, but if I align the carb to it it seems way tilted, I did not pay attention to the factory index position, if they Kato factory have the float set for that marked angle install and I rotated it more to level more gas will fill the float bowl and probably over flow. I dont have a shop manual

I didnt , I just put mine where it looked right. I leaned my bike over until it dripped fuel and it was quite a ways over so I left my floats alone.

we can now get back to the ride itself when h cam and fotos come in I will try to post, I did not wear my h cam, on this ride there is just too much stuff going here for me to have had another thing to worry about. But i did see some h cammers as well as our regular foto takers

Mine also fouled a plug with the stock jetting. I pulled the plug and it had a NGK 7 in it , thought that was a little weird . All I had was a NGK 8 , replaced it with that and runs just fine.

My #1 worry was running stock tires with tubes!!! But i figured 99% of the guys are using tubes, so I would just join the conga line with tube changing gear in the trail pack...I will get my mousses installed this week. it was just a "little bit" rocky out there.

on a Beta note there were quite a few Beta 300RR and race versions and one 498(whoa) Betas really come up off idle very very clean...those guys were just chugging up stuff , we had 2 in our crew as well as our local dealer friend on his 300 for hardcore enduro/extremo stuff out of the box...that 300RR is badass, my TE300 will be tuned into that style. Thats my benchmark

Yes the 7 is the spec plug. My stock jetting was 40pj some n series 3 taper KTM needle and a 168 MJ

Tim I have a mantra never to change factory heat range plug settings, but that's just me, ( 7 being hotter then 8)

I hear you but being the 8 was colder and that was all I had I did it. I have never seen a big bike with a seven

LoM I am happy to have the simplicity of a carb again, it will just take some very minor personal settings for me.
I will most likely have 2 carbby sttings my "Altitude/heat lean setting (90% of my riding) and my Dez/Nat H&H setting (sea level fatter WOT setting, prob OEM manual sea level setting)

as for FI I liked my Mikuni FI much better than my state of the Keihin MX/offroad stuff, I always wanted an accelerator pump for the Keihin FI, I even thought seriously to install a FCR carb onto the TXC310R.....

Motosportz Im thinking it has to do with EU standards for the OEM homologated corked up street legal versions of the 2 stroke enduros, relating to the plug heat range thought.
