DR750 & DR800 owners thread - Page 39

Bluesman, the carbs are off a 1991 gs500. I have aquired a fuel pump for a 850 Tenere and will be trying it out tomorrow so ??????
I will try for pics and answers

OK.....so the decompression lever will pull back and then "click" into an OPEN position.

When the engine starts, the lever automatically clicks back to CLOSED?

Is this correct?

I was assuming that one would have to hold the lever open and then release it at the proper time.....it seems that is incorrect.

Also it is recommended to stop the engine with the decomp. lever. Is this correct?

Thanks,
Ray

Yes to both questions

Thanks for the help....just a afew jitters since I've not set eyes on the bike yet and don't want to do anything stupid .

To change topics - Has anyone seen or have links to photos of the DR750/800 Dakar bikes? I've seen many photos of the bike in the Dakar section of ADVrider but it's always with all the bodywork on.

How close is the production version to the race version? I understand that many modifications have to be made to allow a bike to finish the Dakar, but in the case of my Transalp/Africa Twin, the race version was far from what was offered for sake. The engine was entirely different etc. I'd like to know how close (or far away) the Suzuki bikes are from the racers.

bluesman · 02-21-2009, 02:50 PM

I have collection of all photos I could find with bodywork removed of real Dakar Zeta and various versions. But I can not attach them here it seems...I can drop it to your email if you need them.
Main difference in Dakar bike seems to be 820 cc bored out block, right engine casing cover slightly different and kick started installed.
Obviously there is more, i guess different gearbox ratios, different carbs and intake.
In terms of frame - dakar Zeta did not have rear subframe at all as such. It had huge plastic (may be there was some metal too) pillion with 2 fuel tanks and seat.
Also it have different airfilter with very good protection from sand and intake side seems to be in front of rear wheel with large filtering element facing rear wheel.
Different headlight and cover for it (can be bought on Stefan Hessler DR shop online), sump guard with what I think it water but could be oil. Bike have more clearance and really short exhaust.
Or I just email you photos I am looking at now and stop imposing somebody who knows something about it

my information on DR Zeta is all from Internet, photos and books.

I think now for me (short guy) my 800 and stock 750 feels same weght-wise. So, if you get 800 - unbolt stock exhaust just right away

I´m in the procces of removing stock exhaust but dont know wich direction i should go.. buying a plug & play pro duro, marving or something similar is way too expensive to me due to exchange rates, so i´ll have to buy some titanium or carbon slip on from ebay, they usually sell cheap if you are good searching. ( I got an almost new yoshi carbon TRC for my gixxer for 50 USD

)

wich inlet diameter do you think i should go for? 1.5" 2" 2 1/4" ? i believe the header is 1.5, right?

bluesman · 02-22-2009, 08:22 AM

Well, header is 1.5 but do not go for end can of 1.5.
Go for 2 1/4 and weld adaptor on header or link pipe. I did that using Benelli Tornado tre can and happy with results
Why? Because 1.5 cans are not ideal volume-wise for huge mono like DR.
And avoid carbon. Please please, avoid carbon. And if possible - avoid "thin" and "superlight" exhaust.
I have collection of photos from our DR colleagues with blown to bits supertrapps, carbon exhausts etc. - DR pulses are too much for carbon.

Try to get stock exhaust can from laaaarge displacement sport, sport touring or roadster bike. One of finest ways to go - make and Y-link pipe and buy couple of oval stock aluminium end cans from Ducati Monster 900+. If you do that - I bet your bike will sound beatiful and engine will breathe OK.
