Hi Guys

Don't suppose anybody's got a spare 750 wiring harness laying around.

Mine's in a bit of a pickle. Looks like i'm gonna have to make a new one. 170+ from cmsnl and can't even get one from a dealers in the UK.

Hello Eugene in Singapore,

try the German DR Big shop for carbs. Stefan offers a worldwide Suzuki-DR-spares-service and should be able to help you.

His shop is at http://www.dr-big-shop.de/

If a Windows Internet Explorer-message pops up, click on 'Ja' (this means yes in English). Maybe you don't have this problem if you use another browser. If you get this message, too, and clicked 'Ja' the page will be built up all-the-same. I haven't recognized any draw-backs up to this moment when doing so.

The button with the Union Jack for the English version doesn't work as this site is still partly under construction. But in the grey part on the left, the last button at the bottom, there's a translation-help where you can choose the English language by clicking the arrow.

And, please, don't expect an answer within the next week (maybe it lasts even a bit longer).

Stefan is trying to put his big yellow Rallye-Big on top of the rostrum again in the over 170-kg-class of the Rallye Dalmatia!!!

If you're not successfull by following the above steps ---> pn me and I'll get you in contact to Stefan.

Kind regards, Bambi

135 main jets.
Half of the UNI airfilter taped to reduce airflow.
top speed: 131kph on GPS
cold start knob pulled: 136kph on GPS

135 main jets
Airfilter untaped
top speed: 110kph on GPS
cold start knob pulled: 115kph on GPS

I suspected the problem was in the carb vent tube. I had put an oiled foam filter in the end of the tube there. Unfortunately removing it did not have any remarkable effect.

So, do you think I should try going for bigger main jets? or would it be waste of time because CV carbs just do not work with non restricted airflow (not enough vacuum).
Damn I can not afford a set of flatslides right now...

Wait a second. My SR43 did EASILY 150 kmph on GPS and topped out at 162. With supermoto wheels and luggage it was 155. I mean real speed, GPS. Something not right.

ok, a short update:

i've retimed the camshaft after turning the rotor 360 degrees (out of 720 obviously), just so it would sit in a different spot of the camchain, realigned the markings, and surprisingly the marks are sitting much better now. with the tensioner off they are nearly horizontal. odd. rob was this your theory to rotate it to the next tdc? i must have misunderstood before...

then i've replaced the orings and realigned one of the inlet rubber seals (between the carb and the intake) that was sitting upside down and didnt let carb to sit in properly.
i then checked oil level and drained a good cup of excess oil.
reset the valve clearances.

checked everything - put in my carbs - runs excessively rich.
checked choke cable - no luck.

put in my brothers carbs - runs good. let it work for a few minutes - still runs good. put a bit of gas - runs good. put more gas - runs good. little puffs of smoke come out, but i blame it on the amount of fouled carbon deposits in there that ive been building up with all my tests. the header pipe was getting a tad of glow, very minor after working for like 5 minutes.
I then checked the mixture with a lambda sensor - it was spot on.

At this point i have decided not to play with the CDI's. Back to the carbs.

Although i have cleaned them already, i want to do it all over again. So, what should I soak them in? Coke? :) It's a pitty that i dont have access to a n ultrasound bath...

PS I think with the amount of problems I had on the bike diagnosing multiple problems becomes an impossible job :/ a process of elimination as you say...

Blue, a 4 or 5 weeks ago I saw 164kph real GPS speed on mine, too. There was stock air filter with triangle cut out and 130 mains this time.

Now I have UNI foam filter which is less restrictive, similiar to Stefans latest design. I've tried 130, 132.5, 135 mains. It is obvious the carbs are getting too much air. I'm gonna find some bigger jets and try again.

PS Long shot but worth a try - anyone has a set of second hand TM36 flatslides for sale please give me call. I already asked Stefan, but he doesn't have.

Try adding some duct tape to the airbox opening to reduce the size until your main jetting comes into balance.

At least then you aren't running too lean on top. You don't want to damage that beautiful new piston.

Mait, i reckon you should go back to the stock filter setup until you can afford flatslides. 163kph is pretty reasonable if you ask me
like Ray said, don't damage that piston. i know you have a spare but you're not getting mine back

Mait 130/132.5 no bigger and drop the needles back to original height, I prefer the 130 myself , blue had 132.5 and I think the same exaust can and was happy on the 43, after doing this start adding the tape about 20mm at a time and it will come good.

Wundis , am I right saying you have put back in the old camshaft and after realigning one inlet manifold the bike is fairly good .
I know you are sick of working on the bike but if you just put back in the new camshaft and don,t touch nothing else, also this will save the new rockers 130 bucks worth .
If it runs terrible like before then you know it has the wrong regrind.
If it runs OK then the inlet manifold being miss aligned was the main problem and your carbs too

no, putting back the old camshaft was just an idea, im not going to do this, since as i said it being restored will eat my brand new rockers.

its running on new camshaft now, and runs pretty well with my brothers carbs. my carbs run horible.

so i expect my next post to be full of closeup carb pictures. ill try not to make it look like cheap porn.
what should i soke them in? conventional carb cleaner is boring, and I don't have access to an ultrasound bath.

Wundis I have always used only gasoline and compressed air. Depends what kind of dirt you have in there of course.
