    Great bike it's not a track bike but on the trails she can't be beat.
  3. I have a 2013 DRZ 3x3 MRD/SSW 39FCR Hot Cams stage 1 in/exh What should I expect when I do the big bore? Is it going to be a WOW change? Or just another incremental change? I would imagine a lot more TQ in the low end and mid range? How much of a higher RPM difference? Basically overall, is this going to be a change that transforms the bike the way the exhaust/carb did?

    It has been a good bike to won for me. Plenty of power stock. I did add a big bore kit to it for this year so we shall see how that benefits.

    This bike has come along way from the stock POS Suzuki puts out, but really a solid mild bike turned into a ROCK SOLID fire breathing monster! I'm sure that I left some stuff out but it's been fun transforming this bike into something that I'm proud to own, and a big THANK YOU to all here at THUMPERTALK for helping me make this bike happen!

    Great fun, owned for 7 years and very few problems
  8. I've seen this topic pop up a few times, so I thought I would share my findings. Just over 12 months ago I finished off my 440-kitted XR400 that was fitted with brand-new Kibblewhite valve springs, titanium retainers, Wiseco/Hot-rods 400EX crankshaft (love the electric start!), Kibblewhite black diamond valves (standard size) and a stage 3 Hotcam. I used a 4-play 440 kit from eBay that came with a pre-bored cylinder, a Wiseco 11:1 89mm piston and a Cometic gasket set. I had the head reconditioned and fitted with new stem seals and springs at my local machine shop. The head had a very slight mark from the head gasket firing ring so it was skimmed 5 thou, media blasted to clean it up, valve seats recut and then reassembled. Aside from this I did the rest of the assembly myself on my bench, following the workshop manual instructions for setting up the stud heights in the cylinder. I reused my old studs and rockers on the new assembly. I then got the motor running, eventually swapped over to a Mikuni BSR42 and took it out hard trail riding and commuting on the bike as my sole transport for the last 12 months. I have clocked up 260 hours/12,000km on the XR in that time, doing anything from very tight trails banging the bars off trees to hours on end sitting at 110-115km/h (70mph). I average about 5L per 100km (47mpg) with mixed riding as a commuter. In that time the bike was severely overheated once on the trail from hell (we managed 2km in 4 hours), to the point where the oil started to burn and smoke out the breather. It was quite down on compression after that, it turns out it had a partially blown head gasket. It still pulled very hard though! Which brings us to now. These photos are after the head and piston went back into the machine shop for a clean up. Unfortunately I don't have any before pictures due to time constraints except the first one (I am in the process of moving whilst rebuilding the XR). The piston has had a light buff on a wire wheel to remove carbon, the head has been stripped, valve seats recut (they were showing wear - to be expected after 260 hours of use. Especially considering it spent a lot of time >8000rpm!), new stem seals fitted and bead blasted once again. The bore has been honed and was found to be 2 thou out of round. This is somewhat to be expected given how severely it was overheated. Total cost to bring this motor back up to spec was $250AUD including all machine work & a set of rings and it's ready to go for it's next big trip - a 20,000km trip around Australia If anyone has any questions regarding building a 440, the electric start conversion or otherwise I'll be happy to help. I'll hopefully have some photos & video of the bike up soon once it has been edited. Night and day difference between a stock XR! Camshaft is showing a little discolouration but has no scoring or gouges that can be felt by hand - I was expecting more wear than this. 260 hour old piston. Broken in hard! Note: Piston has had a clean before this photo but the skirts are un-touched. Top of the piston after a quick de-carbon. It will be replaced at next tear down. Piston has some marks from blow-by past the rings but isn't showing any signs of fracturing or scoring. Reassembled for round two Head cleaned up and ready to refit. I have no idea why one of the valves is a different colour either - it's how I got them from Kibblewhite. So there you have it - 12,000km/260 hours in 12 months. $250AUD and it's ready to rock again. Aside from replacing 2 sets of friction plates I have not had to touch the motor aside from normal maintenance.

    Bolt on and go The largest displacement bore kit available without the need to bore engine cases Kit includes aluminum plated cylinder, BBR motocross-grind camshaft, piston kit and gasket Add 26mm carb kit for the best performance gains

    Big Bore Kits

    I was reading Ramz site and noticed he has the first 283cc big bore kit that was produced. He mentions a larger kit is in the works too. I'm guessing since the head isn't shown in the big bore pictures that it is getting ported too... Then he posts picture of 2 packages that look like new cams... He has something special up his sleeve.... Details would be great. Thanks

    Great commuter with some longer road potential hampered only by the lack of a 6th gear and a rather small tank. 434 Cylinder Works BB kit and 39mm FCR carb helps bring the motor up to a very composed 80 mph cruising speed quickly and will sit there as long as your tank or your butt lasts. 320mm Brembo disc and calliper up front will bring it to a halt at G's exceeding what your stomach can hold in.
