head

head gasket failed on the rc dealer said when i bought it that if i had it serviced with them even though they knew i was going to track it they would honour warranty, i had the ecu flashed by them as i put a pipe and air filter on it 60 mile later the bike almost doesnt start and then over...

Hi all, running a 2014 390 as a race/track bike only and having head gasket problems, just had the head machined due to normal warp issues with early models. Just been to a track day and the head went again in the last session, no noticeable overheating issues after doing cooling mods, ( better...

Left side. Is it supposed to be unplugged like this? What is it for anyway?

being that my left mirror broke due to a tip over. I took the rest of it off and took out the bolts until I buy a new mirror. Now that I have a replacement mirror I cant seem to find the bolts I took out. Thought about going to HD to get a set then realized the head and stem are a different size...

I started racing my KTM at the beginning of 2016 and the bike has progressed along with the season. I started out basically stock and the most beneficial mod I've made since the beginning has been the the suspension. Recently I installed the Cometic head gasket to prevent blowing a gasket (which...

Got Her back form repair with a New Akrapovic race system and a Double bubble wind screen. Love this bike. Hope It keeps from blowing another head gasket because I was going nuts not being able to ride.

A bit of a clunk developed in the steering head so I decided time to check the bearings. Guess who was not even finger tight, and it even had loctite on it. Just a warning--check and make sure it's torqued and has loctite. Spec is 52Nm or 38.4 ft/lb.

We took on the NEXX line, because we were BLOWN AWAY with their latest line. These helmets stack up against Arai and Shoei in every regard.Unfortunately, helmets just don't fit our business model, so we're blowing out our remaining stock. We have one each, of the units below. Both size large...

What’s the cause of the blown gaskets? Is there any check that could be done to prevent it? It looks like when it happens the damage is all over, cylinder, piston, valves, head. Does anybody know the estimated cost of rebuilding the engine from that?

Sold, thank you.

At 15,684 miles I decided I had punished the KTM's mill long enough. I broke down and adjusted the valves. Of course, this required the acquisition of Harbor Freight's 1,000 # motorcycle lift that taunts us with that $299.99 coupon each month in the back of the MC mags. It's sweet! It all went...

Just finished this 'light' build. Same bike in both graphs. Bike configuration is; stock exhaust, K&N filter, open lid, with a PCV. The blue curves are the stock engine, with before mentioned external mods, tuned. The green curves are with thin gaskets installed, head porting, valve touch up...

We normally have access to, and can carry all brands of product, but choose to carry only those items we believe in and are passionate about. Such is the case with NEXX helmets. If you're unfamiliar, these are world class lids, at a quality level seldom seen. They're packed with premium features...

Anyone had any problems with their steering head getting loose?

2015 Entry-Level Sportbike Shootout - Motorcycle USA The KTM is actually heavier than the Honda, although far better. Strange thing I'm noticing in all these reviews is that the Yamaha R3 seems to be all over the place depending on who reviewed it. Some say the brakes and suspension are...

I'll just post this here for you guys. Beginner-ish Sportbike Shootout + Video Quick background on me... I started off with a deposit on an RC 390 back in march but shopped bikes heavily while waiting for it... Ended up with a new R3 last week partly due to the street price being $1500 -...
