Hello all BIG lovers…
So, some more details-
For now I haven’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).
The bike dry weight (the real weight- not like Suzuki…) is- 170 kg.
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…
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

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

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

Hi Manos we are honoured, you have been a member for 2 years and we get your first post, I quess better try and answer well

Details as below


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!



Engine



Based on DR Big Single Cylinder Four-Stroke



Capacity



741cc



Valves

Hi and thanks for the info. Not much available on the net Iím afraid.

Yes, Iíve been a member for quite some time now but havenít posted for various reasons, which I donít think are important or interesting enough for publishing. Thanks for the welcoming note.

Iím from Athens, Greece and I ride a Honda CB1300.
I also have an NX650 Dominator which is presently in pieces and will be heavily modified. This is part project and part experiment.

Thanks again

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.
