It's a holiday weekend here in the states...  Who it riding this weekend???

My wife is traveling to see her family and leaving me behind...   :(  So I'm planning on making the best of it and planning on a solo rife Friday, and a group ride Monday...   :D ;D ;)

It seems as though you found the problem...  keep an eye on it and keep up informed.

I agree with Ron... you're getting pressure into the system from somewhere...  I'd replace the head gasket.

Flettner I always enjoyed following your TPI research (even it much of it was WAY over my head)...  Looking forward to see what you've been working on...  Please post when you can.   8)

The week prior to race day, it rained... and it rained some more.  It did clear up on Sunday (race day)  but the track was a muddy mess...  I did not ride the track, but instead setup at a few hills during the pee wee races. They needed assistance to get up some of the hills.  For the adult races I helped with scoring and time keeping. 

Here's a video someone from the race posted.  The soil a the park is mostly clay...  so when it get wet, its like riding on ice.  The video doesn't give the true perspective as to how muddy / slippery it was...  Although as you'll see many had to stop and take a break, as the extra effort required really sapped the strength of many riders.

Looking forward to the weekend as I will be working a cross country race.  I worked one last year and really enjoyed myself.  I especially enjoyed helping the little guys / gals on their little PW's.  We had one little guy who fell over while trying to get up a little hill, several volunteers jumped in and picked him up, put him on his bike and got him up the hill and encouraged him to continue on...  He was almost in tears and scared, but we got him going again and he finished the race.  I happen to see him and his family after the race and congratulated him on finishing...  the smile on his face was priceless.  The thank you from the parents was heartfelt as they saw us pick him up and get him going again.   

In the adult classes, I helped several downed riders, and even had a guy ask if I had a spark plug as his was about to foul.  Of course I did... as I about to pull the plug out of his motor, I see the issue and mention to him to turn off the choke.  I put in my fresh plug, he turns off the choke and it fires up 1st kick as a 2 stroke should...  he thanks me and takes off...  he found me after the race to thank me, and wanted to pay for the plug...  I think I can cover the $2.00 for the plug...  he was so embarrassed about leaving the choke on...  :o   

It's been a little wet, but hope it dries up by Sunday.  I'll be on the track following the groups looking for those that need assistance.  Looking forward to a fun day

Just an update... as I thought about the quad... when I got it, it had a leaking crank seal which I fixed.  Since I was still running the same jetting of course that would make it running rich.  So I took a chance and turned out the air screw to over four turns.. it was running better.  So I dropped the needle by raising the clip to the 2nd notch and set the air screw at 2 1/2 turns... better... turned it out to 3 1/4, even better.  Now it has just the slightest hint of a hesitation. I think I’m going to leave it for now as the motor need some time on it before I make any more adjustments.  I’m just happy to finally cracked the jetting issues.  It now does run pretty good... at least for a quad.

Just an update on the 2 stroke quad.  Just a reminder, Polaris Xployer 400, with piston size one over.  I’m struggling with jetting.  I’ve gone back to factory settings.  Idles great, but bogs when coming onto the main. If you feather the throttle you can work through the big and she’ll run well... it’s difficult to access the carb with the air filter boot in place.  If I pull the air filter, no bog, revs out with no issue, no bog, no hesitation.   Put the air filter back on, and she struggles.  I’m thinking it’s too lean with the air filter in place..  I’ve adjusted the clip position and have tried turning the air screw in and out with out much success.

One other thought...  this machine in oil injected.  When I put her back together, all I had was bel ray premix, not 2 stroke oil for oil injection systems.  I’m wondering if that could be the underlying cause...

Help me out guys, I’m stumped

Awesome...  I think the 1st pic says it all...  to me it says No worries, I got this...  8)

I find myself in a in a strange situation...  My kids are grown and having kids of their own. As we all know spare time is precious with a young growing family. My son's baby is 1 month old, so he'll be lucky to get out a few times this season. My riding friends sometimes find it difficult to find the time to ride...  so I decided if I want to ride more (which I do), I just need ride solo...  I can usually hook up with someone at the trail head or sometimes even on the trail, but lately I've enjoyed going it alone. I've found sometimes there's nothing's better then finding a fun section and riding it over and over, testing out different trails / different lines / different sections without thinking about the group or riding buddies. When bouncing off trees, I can rides with out thoughts of making sure my riding buddies are able to clear this obstacle. I will concede when solo I do back down the pace a bit and will take the easier trail, I've found that I seem to put in more miles when solo... yes I admit it's on the easier trails, but I'm still busting down the trails...  Isn't that what it's all about.    ;D

Just as a safety measure when riding solo I do carry my phone and have a few friends near the riding area that can bail me out in-case of an emergency.  I also wear my helmet blue tooth communication device and can make a call with just the push of a button on my helmet.

How many other ride solo?

Took her out again over the weekend...  A buddy (typical 4 stroke rider) came along...  While I'm hitting the bigger hills at warp speed and coasting up the last parts of the hill, he's the type of a rider that waits until his back tire gets to the hill climb before he gets on the gas.  This things a tractor and should just power up the hills... yea, sure... and he can't understand why he struggles on the bigger hills.... momentum is always your best friend....  So it was a ride where I'd ride ahead, stop and wait, sometimes turn around to see where he was, or I'd scout the trails ahead looking for the easier trails so we could continue riding.

Didn't put in as many miles as last time... but still got to enjoy a day on the bike

The new bike is simply amazing.  So smooth...  I think the grunt / torque is not quite at the level of my old 380, but pretty close and so just much smoother. The power comes on quickly, but not where it's like a light switch.  It's not abrupt in your face power, but very controllable. This engine has a counterbalance which is supposed to reduce vibrations...  I can only say, it just feels so smooth.  The new grips were a big help.  I had very little hand numbness, (so little I can't recall any) it was well worth the pain of switching grips.  I lowered the tire pressure a bit,the front end felt more stable, the rear was better, but I'm still not digging the tire.  It too new to just ditch and purchase a new one in the brand I prefer, but it was better than the last time out.  E-start.... I have absolutely fallen in love with s-start.  When you are in the woods on a weird angle, and your're tires and to balance and kick the bike...  I just stab the e-start and braapp away.... At this point I'm actually happy with the stock gearing, which is odd as I always adjust the gearing to fit my style... Usually I add a tooth or two the the rear, (the 380 was the exception I geared it up a little).  On this 300 I think they got the gearing right.  The brakes are top notch. You can stop on a dime in all conditions with confidence.

I'm going to hold off on the idle screw adjustment as it's a pain in the arse to do, and I really didn't have an issue with it this ride...  Yes it's a little low for my taste, but it works so I'll leave it alone (for now)

Braapp on gentlemen

So glad to hear / see you've landed on your feet.  I'm even more chapped to see you have regained the burning desire to roost everyone without regards to race / sex/ gender / spode-ness .  Welcome back big (err smaller) guy welcome back.

To be made honorary president of MIRA (Mentally Ill riders of America), that my friend is a bucket list achievement... Coop is smiling down and saying roost em all....

Finally got the grips swapped out.  In all the years I've never had a set of grips that were that difficult to remove.  One thing I do like is the clutch side utilizes a sleeve (looks like a throttle tube) that helps reduce / remove the vibs from my hands.  Unfortunately, getting a grip designed to fit the bar, onto the tube was a nice challenge.  Being old school and cheap, I've not used grip glue in a number of years.  I always use my wife's hair spray.  (No, its not mine, I'd need more hair for that to be true.)  The hair spray allows me to slide the grips on, but when it dries, it leaves a sticky residue which keeps the grips in place.  The throttle tube grip was not too difficult.  Slid into place without too much fuss.  The clutch side was a bit more of a challenge. But after a few choice words and a lot of force, the grips are on, and the hand guards reinstalled. 

This was supposed to be the easy mod...  :o  Next is the idle screw.  I'm hoping I can loosen up the thread lock and adjust it to where I want it.

Thought I’d pull off the grips 1st... something simple... NOT!  Every squeare inch / CM is glued with some kind of super glue.  The grips are fighting me every step of the way... I will not give up... I will win.  I’ve had to resort to using brake cleaner to help dissolve the glue... WHAT A PAIN IN THE ARSE! I’ve never seen grips with this amount of glue holding them on...  grrrr 🤬🤬🤬

Purchased new pillow top grips, and I've been looking into an idle screw modification.  In their infinite wisdom, KTM set the idle via a set screw which opens the throttle body slightly (the same as raising the slide in a carb).  Of course they've lock tighted the screw, so idiots like me cannot adjust it. KTM says to increase the idle to open the air / fuel screw.  I do not want to lean the bike out more, as based on research, I've found the fuel / air mixture is just slightly lean.  Many have modified the idle by either replacing the set screw with one from Slavens or by simply turning in the set screw, thus raising the idle.  This mod also allows you to turn in the air screw a little as well, making the bike spot on to just slightly rich.  The issue with the mod, is the set screw has such good locktight that even with heat it's difficult to move...  Many have gotten over aggressive with the screw and stripped the head (which now will require a machinist to remove the screw), while others stated that with a little heat and persuasion it wasn't too difficult...  so with crappy weather this weekend, I hope to dig in and see what I can see...  I'm sure mine has enough locktight so its now fused itself to the throttle body...   :P
