Broken head or valve cover bolts still an issue??

Recommended Posts

I was up riding the other day and my buddy had a crash on a big uphill. Being the good friend that I am, I went up to jeer and humiliate him before helping him pick his bike up. When I went to help him, I laid my bike over, on the hill, as I have done many times, with the seat facing up the hill. (Like I said, I have done this quite a few times on really steep hills, as the bike is almost standing upright by laying on it's side) When I started my bike, there was a ton of smoke coming off of my motor and out of my exhaust pipe for about 1 minute. It almost seemed that some oil got up in the cylinder, and out on the header. I have heard of the broken head bolts and thought that this problem was cured for the 05's. It's a 525EXC and any help would be totally appreciated. I even wondered if the vent hose had maybe got a hole burned in it and leaked some oil on the header pipe, however, that would not explain the oil coming out of the exhaust. Anybody got any ideas?? Thanks for any help !! :):)

Did it stop smoking after a minimute or two? If so I think you had it leaned enough, maybe the engine over full of oil? that some oil went up the crankcase vent and got to the carb, engine ingested it so it smoked for a bit. That is a better problem then re pouting the hose and have the crankcase breathing unfiltered air.

To check the bolts, just above your sparkpug there are two bolts going down into the engine, just make cretain they still have heads on them, if they don't oil & smoke would have increased.

      Looking for something a little lighter and faster to supplement my xr650l and I think this bike might fit the bill. I'm hoping there are some owners here who can give me some insight into the typical experience with this bike. The question I'm most concerned about is how many hours these engines last before needing a rebuild with normal trail riding? Also, how do they handle in technical terrain? How about on the road? 
       
      The machine I'm looking at has about 75 hours and 1,500 miles on it, all stock other than a lectron carb, and comes with some dualsport lighting not installed. The current owner's asking price seems pretty high at $4500, but he seems to be a communicative, eager seller, which is practically unheard of in Upstate NY where the vast majority of dirtbikes on Craigslist are owned (or "owned") by rednecks trying to flip them. I'm willing to pay a little more than market value for this reason.
       
      Thanks for any input!

      Hi all,
      I got a set of the Axis passenger pegs to fit my 14' 500 exc. The bike does have the alloy sub-frame, but I'm curious if anyone has used this set up with success without destroying the sub-frame or their wife/gf? 
       
      Short trips like errands and rides out to the coast for hiking. 10-15 miles on the longer rides, and likely 0 miles on the highway, as she is not super stoked about riding. But our job kinda doesn't allow multiple vehicles. Yachties. Also shopping a sumo set up at the moment too. 
       
      Thanks folks!!

      Recently,I took a trip out to Colorado for some R&R on a family vacation. I brought my riding gear and had planned on renting a bike, but I was too late and at least what I looked at, there was no availability for my timeline. Bummer, since I'd not ridden the rockies in over 4 years, something pretty special when you live in flatlanderville (Florida)! 
      But, behind the scenes, a couple of TT'ers were at work! Through TT, we recently hired a fine, young gentleman to head up our advertising sales team,( @Freemotion ) and he pulled some strings with a local who had a well equipped  KTM 450XC-W that is his back-up machine. His new love is a 2019 KTM 300 TPI and it was gorgeous!
      So, a HUGE thanks to @Freemotion for greasing the skids in getting me a skoot and to @G 9.5 for generously lending out his bike to basically a stranger. The weather was great, so was the company, and the riding was epic as far as I'm concerned. I'm still a bit humbled by the generosity, so I wanted to share a story that I bet isn't as uncommon among the riding community as one might imagine.
      Dirt bike people rock! 🤘

      Hello TT peeps. I currently have an 11' Ktm 450 exc which i am converting to sumo. Still on the fence about getting cush drive rims or standard rims. Not too much info on what cush drive does for wheelies. I know its smoother on the tranny and chain but will it make much of a difference with slower wheelies/stunting? I had a DRZ with standard rims and slower wheelies were very choppy and almost impossible to control smoothly. Any advice/tips/help will be much appreciated. 
      Also.... will 5" rims be pushing it for chain rub? Should i just stick with 4.25"?
