I have a sikk-MX trail bike. And tried to extract a snapped bolt....snapped the easy out inside the bolt casing/shell(I drilled a hole through said stick bolt). I cant figure out which 52.4mm cylinder head to replace it with. Does anyone know? I also cant figure out the headlight wiring to my tusk headlight...if anyone has any schematics for that...please help. And does anyone know what larger/largest size tire or rim will fit on these bikes? Cuz these tires are pathetic.

Hey everybody, let me start this off by apologizing for not only beating this dead horse, but pulverizing it into a thousand little pieces. I have a 2007 WR450f and I am converting it to a supermoto. I've purchased a tusk wiring harness, Headlight Head Lamp Bulb Socket, turn signals , flasher relay, horn, brake switches, a handlebar switch (with hi/lo, horn, and turn signals) and I also have a keyed ignition switch. I decided to order all of these parts because they are the same parts as the guy from THIS VIDEO. I did this so I could just follow his steps and not worry about anything. The first issue came up when I found out his method of using that headlight socket to get power to his relay wouldn't work because 1) His bike is newer than mine and uses a different headlight bulb etc and 2) It appears his bike has a headlight relay and my '07 does not. He uses that relay to cut the power to his electronics just by using the factory push on/of switch. So killing power to the electronics without a switch isn't possible because I dont have that relay...okay thats fine. I wired my stock headlight to the hi/lo beam on my new handlebar switch and it worked just fine for a bit...and then it would only work on the low beam and when I turned the switch to hi it would turn the light all the way off....not sure why it worked fine one minute and the next minute this happened but OKAY I can live without hi/lo beams. Here is what I did step by step with links to what I watched/looked at to guide me. I took off all my plastics/gas tank etc and ran the harness through the bike. I installed the handlebar switch, horn, turn signals, ignition key. I wired the new headlight socket up but had to take that out and rewire it back to stock (kind of?) and in doing so the hi/lo worked for a minute but then only hi/off worked. I plugged in the turn signal, horn, flasher relay plug from my handlebar switch to my TUSK wiring harness. I took the wires coming from my stock tail light and ran them through and connected them to the tusk wiring harness. Plugged the turn signals into their respective places on the harness. I then connected the tusk wiring harness to my battery using the supplied connectors and double checked everything was in the proper place etc etc. Turn on the bike....NOTHING works. I mean nothing (except the headlight) Before I put the blinkers and everything on I had already hooked up the pressure switches to the front and rear brake and had it working fine. After I switched the brake pressure switch plugs into the tusk wiring harness the brake lights didn't even work.... THE FUSE!!! After I got over being bummed nothing worked... I started going through everything to see what was wrong and the little fuse thats included with the TUSK wiring harness was blown....but why? I followed instructions from the TUSK install video itself...why did the fuse blow?! Do I just get a new fuse and try again?! The only differences between this video install and what I did is I didn't use their "kit tail light"I kept my factory one I just cut their harness plug off and wired them individually and I also didn't get front turn signals only rear ones. ANYWAYS....Since I wanted to go riding the next day and needed my brake light and headlight working I unconnected everything and put everything back to how it was when I started (after I had put in the front/rear brake pressure switches. I am now (not before) getting my headlight power straight from the battery (I think) which is spliced into the brake light with the pressure switch wires. As of now the headlight works, the running tail light works (very dim) and the brake light works (very bright). I know someone is going to say I need a stater/rectifier upgrade but according to everybody, I dont. Lots of people have done what I am trying to do without those upgrades and using the same parts I have but for some reason I am just coming up empty with this install. At the end of the day all I REALLY want is a working headlight, brake light, and turn signals. If someone can tell me step by step instructions on how to either A ) Make everything work or B ) Make my headlight, brake light, and turn signals work...I will be forever grateful. I am honestly willing to send you money if you can help me figure this out.... Again, I am so sorry I know how much people hate old problems being brought back but I genuinely need help. I am not an electrician and know only the VERY basics so after I follow instructions and shit still doesn't work.... I am just lost....PLEASE HELP ME I DONT KNOW WHY THIS IS SO HARD FOR ME TO DO!!! Here are links to each part, video, and diagram I used: Install Videos: Video I used to order parts from/attempt first install from Official TUSK enduro kit install video Handlebar switch for headlight hi/lo  (I used the diagram they show in this video and it worked at first but then only worked as on off/hi beam switch) Parts: Wiring harness Turn signals Flasher relay Handlebar switch Brake switch x2 Horn Ignition Key Headlight socket (not using anymore but was installed at one point without bulb)

I am converting my 2005 Honda crf250r dirt bike into a street legal supermoto but have run into a problem. I used the tusk lighting kit and upgraded stator to do the conversion. Everything is working on the bike, turn signals, computer, taillight, on/off switch, ect. except the headlight!! I simply cannot figure out how to wire it to the tusk harness. Since its a race bike, it didn't have an existing headlight. The headlight I bought is the Poliosport Halo. Included are the diagrams to the headlight and the handlebar switch. If someone could explain how to go about wiring the headlight I would really appreciate it.

Hello all, New to the forums but not too new to this bike. Long story short it was stolen 6 years ago and finally recovered 8 months ago. I have also moved across the county in the last 6 months for a new job. I was mostly wondering what all could be done to make this a decent adventure/ dualsport bike. I do have a new mikuni 38mm pumper carb on and I currently have it set up for around sub 2000' riding. I was wondering if I were to take it up into the mountains at around 6500' if I would need to rejet the carb at all. I am a complete novice to large mountains as previously I was on the east coast. Also wondering if anybody has fabricated a crash bar for the gas tank and a rear luggage rack with supports for some panniers. Anything helps, TrendyB
