    Hello all BIG lovers&#8230;<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
    So, some more details-
    For now I haven&#8217;t done any modification with the engine and carbs' (will prop' replace them to mikuni fcr) the air filter is an open uni filter with the original air box (with some modification). <o:p></o:p>
    The bike dry weight (the real weight- not like Suzuki&#8230;) is- <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:eek:ffice:smarttags" /><st1:metricconverter w:st="on" ProductID="170 kg">170 kg</st1:metricconverter>.
    Next to come- changing the rear of the bike- swing arm, rear frame (to aluminum), wheel hub and rim (original is so heavy!), led lights and more&#8230;
    15-20 kg less and I will be very happy.
    Because of some small problem 10 years ago (the bike is 1993 model) I had to open the engine (about 80K then) and decided to give it a full overall. The bike has now more then 200K on the same engine!!!
    Excellent bike!

    the pic' is from about 2 years ago and it's not updated.........(many changes since then)

    it's great bike and great work!
    I feel inspired now to buy second DR and turn it into that kind of machine.
    My current DR just have to be long-distance 2-up capable, so lots of stuff I can not get rid of. But I think I should buy second one and turn it into 160 kg offroader.

    Please keep us posted, it's really inspiring!

    One question - for front forks - did you have to make custom yokes to fit or you used CRF tripple tree?

    thanks,

    i used the CRF tripple tree and worked the CRF steering axle to fit the BIG. they are allmost the same (same length, and lower bearing)...i was looking for a very rear bearing (top bearing) that will save me that, didnt find...
    the front wheel is the original and the caliper was adjusted to fit the CRF fork.

    some pix from the way later on.

    and- hello elephant man :freaky

    Can relate to those motorcycle analagies but you probably wouldn;t like it here in NZ we dont have anything nuclear here:kboom

    How have your mods affected the DR on the road,:ricky for example losing the fairing, and did you notice a performance increase with the loss off wieght

    1998 European Season Ended
    Our European season ended with a very nice 21yr old German lady named Katja Poensgen winning the championship riding a BMR-Suzuki. She achieved this by winning 4 out of seven races with one second place & 2 DNFs.

    The BMR-Suzuki she rode is a very interesting tool. It may have started life as a DR800 motor but that was long ago & far away! It's creator is Rupert Bainzel, and apart from a lot of bottom-end work, the motor features a machined-from-the-solid top end, with an Apfelbeck type of cylinder head where the valves are arranged radially, with exhaust & inlet ports placed diagonally. As you can imagine, this calls for some hairy machining of cams, they are conically ground. It's watercooled and fuel-injected & gives over 90BHP from 741cc at 8000 & peaks at something like 9300rpm. Since this represents a BMEP figure of something in the order of 215psi it is a considerable achievement.
    Of course, this didn't happen overnight, it's taken some years to develop it to the present pitch and I know that Rupert won't even think about how much it's cost!

    I think if remember right they also got rid of balancer shafts too.
    That's what I read on Inet about it. They also mentioned that attempt to use aftermarket cranckshaft was failure (aftermarket or self-made item could not survive race) and they came back to original cranckhaft which suprisinly had no probems or failures.
    There is still Turbo as an variant of boosting power.

    Hi All,

    Proud owner of a '93 DR800. I've drooled over this bike since I was a little kid and my dad brought home a Suzuki brochure. Spotted one online for a decent price and had to have it! I bought it from the 1st owner, he's owned it from new and has really spent some money on the bike. He now regrets selling the bike, he bought a new BMW and a few months later he said he wished he'd never sold it...

    It's had the head flowed, stage 1 crankshart, K&N airfilter, Laser Produro open exhaust (with custom baffle), custom welded toolbox below bashplate, heated grips.

    Net result: 62bhp.

    I love this bike, of all the bikes I own it's the most fun. My Tiger is better for road & long distances, but for slamming through corners, nothing beats my DR.

    Will put up some pictures when I'm back on my other PC...

    Don't think I'll ever sell this bike, I'm getting the frame powdercoated, probably next year...

    JB

    if you have a dr800 and you think off selling and buying a new xt660z...save your money and upgrade your BIG!!!
    he's much much better and you will have a lot of fun on the process.
