    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.

    Great bike it's not a track bike but on the trails she can't be beat.
  6. 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?

    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!

    Cylinder works BIG BORE kits?

    Hey just wondering if anyone has any experience with this and if they are somthing to stay away from? They look very inviting on ebay and for the price....

    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
  11. 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.

    Love it, it gave me some problems before the rebuild but now it's better than ever. Big bore gives it crazy bottom end and the cam makes up for that loss off the top. Awesome bike all around.

    Great bike, has 77mm 277cc kit in it.
  18. Hello to all TT's I have created a page on facebook called "Clean Rebuilds" because the garage section of TT is not available. I have posted a few videos and pictures of bikes I am currently rebuilding. I am NOT selling anything here and this is NOT a business.There has been a bit of interest so I thought it best to point out a few things. I am not a qualified engine rebuilder or mechanic, and this page is NOT a how to "step by Step" guide on engine rebuilding and reapirs. It is purley informational based on my experiences. I am not seeking power or prestige and certainly do not profess to know everything. This is just a hobbie for me. My motivation behined this page is that I will be learning as I go and I hope you can enjoy and benefit from some of my experiences. I have been working in and out of the automotive indusrty for 20 years. For the last 10 years I have been working as a sales / estimator and engineering design, for our family engineering buisness. Currently alot of my work is commerical heating, ventilation and food drying processes. I am also not qualified here but have gained skills along the way. I have only recently got back into bikes after a long stint of night life work. Everything I repair is information gathered from either the internet and other engineering books but mostly I buy and work from the specs in the aftermarket repairs manuals. I hope you enjoy the page and can benefit from some of the tools I have made and lessons I have learned along the way. Thanks and have fun! https://www.facebook.com/CleanRebuilds

    Big Bore Experiences

    I'm curious as to what your fondest/ most memorable experiences with your big bores are. Now, I'm not talking about your 144, 265, etc. I'm talking about the bikes real men ride CR500s, KX500s, and what-have-you. Yes, being roosted by one does count as an experience Mine would have to be all of the conversations that mine has started while I was at the track, as well as when it threw me 8 feet when I tried to start it.
