    Great bike, the handling is second to none. The bolts seem to be pretty cheap but overall this has been a great bike for me!

    Big bore + cams

    My 01 E model is definitely due for a major service and i'm sure that the cam chain will need replacing and the valves shimmed among the other regular bits to get done so it's got me thinking about going big bore and upgrading the cams. I wanna get some opinions on my thoughts and the below upgrade kit I've found this on ebay among a few others, I've linked this one as it has JE piston which seems favourable based on everything i've read. http://www.ebay.com/itm/231190733204?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT http://www.ebay.com/itm/231190733204?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

    compression on new?

    Quick question... I had 150psi on old rings in my yz144 and just put in a new wiseco and TiN ring and kicked it over and got 120psi. I'm guessing I'll need a couple hours of break in time to see actual cold crank comp?

    Athena big bore

    Anybody ever use the Athena big bore kit on a 2102 RMZ450? How does it run? Vibration? Mapping? Clutch?
  11. The story begins with simple installation procedure of a BIG BORE kit that we ordered from USA . The manufacturer (CYLINDER WORKS) and the dealer send us the correct kit and so far so good !. The bike is a KTM 250 sx-f ,2011 model and bellow there are some photos for you, just to see how careful I am throughout the process . ........ I change the valve seals and the exhaust titanium valves and springs with the PROX steel kit and make a little polishing on the intake and exhaust ...... Put the cylinder-piston on and always with guidance from workshop manual and correct clamps... .. AND READY ... Until now we where happy !!! We start the engine ,and everything seems to be ok! Began to make the first ride and…… DISASTER !!! The engine start bleeding OIL from the hose-tube !!!!!!!!! I thought its normal if it is one-two drops but unfortunately didn’t STOP . We did one more ride to see what happens and still BLEEDING. Back to the WORKSHOP. DO YOU HAVE ANY SUGGESTIONS OF WHAT TO CHECK OR DO ???

    Suzuki DR-Z400S (2007)


    I love the DRZ. It is a pig and not the best performer, but I will rebuild this bike over and over before I ever sell it.

    Suzuki DR-Z400SM (2006)


    2006 SM model - Bought it in 2008 with 1800 miles, use it for commuting and riding on the weekends. Easy to work on and LOTS of stuff available for these bikes to make them better. Stock they are sort of a pig. Dropped a valve @ 71982 miles, had almost 60K on the Stroker crank and BB... Can't ask for much more from a single cylinder dirt bike. Several different motors and configurations over the 88K miles. Currently back with a stock bore and "E" cams. Still runs great and fun to ride, I miss the extra torque from the BB and BB/Stroker.

  15. Hi, everyone. I'm new here, so please pardon me if this is against the rules in some way. To get straight to the point, there is a big bore kit I would like to buy, but I need partners to go in with me. A little background on my project: I started with a 1992 TW200, and using the conversion information from users of tw200forum.com, I began to make a TW250. First I changed out the transmission, clutch, and crankshaft, among other things, with those from the 225 line from Yamaha (TTR225, TTR230, XT225). Then, when planning the top end, I came to know about Engines Only, otherwise known as XR100.com, who make performance upgrades for a selection of dirt bikes, one of which is the TTR230 (http://www.xr100.com/ttr230.htm). For those of you unfamiliar, the TW200/125/225, and the XT/TTR 225 series, as well as some ATVs, have many interchangeable engine parts, so the kit offered for the TTR230 on his site could potentially be a bolt-on upgrade to those bikes listed above (any below 225cc will probably have to have crankcase hole enlarged), and the piston alone could be a stock-bore, high-compression upgrade for an 08-12 XT250 with 16mm pin (call him to ask about clearances). The problem, and reason I'm coming to you for help, is that he has had very few customers wanting the kit lately, and is considering discontinuing it. His custom pistons are the key to the whole project, because they are the only 74mm Yamaha piston available with a 16mm wrist pin, and a compression ratio of 11.5:1 (stock is 9.5:1), and apparently, they only need 91 octane. The place he gets them requires a minimum batch of 4, so if I can't get enough people together, he probably won't consider ordering. I've posted this here, TW200Forum, and AdvRider in an attempt to round up a group of buyers, and to drum up business for the seller, because he's a nice guy. If you would like to ask questions, I'll answer what I can through PM, but you can also call or email him through his website: http://www.xr100.com Thanks everyone, and nice to meet you, John.
  16. Modifications: FCR 39mm, Stage 2 Hot Cams, MRD Z Pro full exhaust, 3x3, steel braided brake lines, fan switch, DRC taillight. I high sided and had to replace the top triple clamp and stabilizer. The Zeta Handlebar Clamp kit (triple clamp and SX stabilizer) went on nicely. The DRZ ignition plate required a little modification to bolt onto the new Zeta Stabilizer or relocating the ignition switch could also be an option. I also had to replace the barkbusters. As I began shopping I compulsively ended up buying everything I could. Zeta levers and barkbusters, Zeta bling (gas cap, tire caps, oil caps, engine covers, DRC bolts, Carbon Fiber Guards), wide footpegs. More photos coming soon. Modifications purchased but not installed: Cylinder Works 434cc Big Bore Kit with Vertex Piston and JT 39T steel rear sprocket Before After

    DR350 Top end rebuild?

    Gday, Has anyone ever done a top end rebuild on a dr350 or even just the rings?? My dr350 blows abit of smoke which is from most likely worn rings, i ride it pretty hard so i dont blame it Would anyone know how much $$$ for the whole top end rebuild or just the piston and rings or even just the rings I might do it DIY just to save money, any advise would be great Cheers toby
  18. I have been doing my homework for the inevitable big bore kit to go into my L. Came across a kit that just got announced. http://www.prweb.com/releases/2014/01/prweb11477156.htm So this is just an announcement, and the website does not yet reflect the kits, much less the different stages available. This kit appears to be different from the other options in a couple ways. The three main options I see right now for big bore kits are the following: 1. B&B Cycle 305cc kit. Runs a 12:1 compression ratio piston. http://www.crfsonly.com/catalog/product_info.php/cPath/290_292/products_id/5146 2. The Takegawa kit, which comes in at 305cc, with a 13:1 compression ratio piston. They also have camshafts available. http://www.takegawa.co.jp/products/detail.php?product_id=2651&category_id=412 http://www.takegawa.co.jp/products/detail.php?product_id=304&category_id=412 3. The newcomer: Millenium Tech. Only 285cc, but sports a 14:1 compression ratio piston. They include a CNC ported head in the Stage 2+ kits. There is also mention of cam selection. (see link in original paragraph) So with that said, what do you guys think? I know we have had several threads discussing big bore kits, including the invaluable CRF305L owner's thread, so I am mainly focusing on what this new option provides. The head work and the higher compression ratio really have gotten my attention. Correct me if I am wrong, but I seem to remember reading about the head on our bikes sorely needing attention... A complete top end package could be pretty darn attractive. The price will determine how many beers I need before I find it attractive.
