looks the goods. the only issue i can see, whether or not it matters is that the filter is flowing backwards with the mesh to outside air and the foam element towards the carb throats, giving the bigger surface area on the inside, though i think the pre filter should sort this issue out. i like it.

Rob, would you use this setup with flatslides or would you be looking for more air again?

OK.

I think I understand it now. Nice job.

It would be helpful to know what part number UNI filter you used.

Excellent job as always. What other secrets do you have sitting on your bench?

Simon , I looked at it and thought the same thing but trying to pull the foam off I think its not possible it too well made anr the foam looks like its moulded in the polly ends.
the foam is fairly open so it breaths actually to well and I would not use this filter for dirt riding by its self so the inner filter or sock doubles the thickness .
The main filter is what I use on the yellow bike, with the same sock sretched over the outside as the whole set up is in a ally box that I made.
Just that the air flow of the 2 is in reverse.
IF I was going to use pumpers so to get the max performance and wanted to use the standard plastic air box I would also do the top air box mod as well as all of this together might affect BST carbs in there standard form
Give me ring and I can explain it a bit better.

Fearing for the worst I pushed the e-start button, and surprisingly the engine turned, but was turning with a weird noise.
Considering that the bike has 50kkm on the clock, and the previous owner "restored" the rocker arms (not sure what that means though), I was almost guaranteed that the problem was rocker arm-related.
And my crystal ball was not wrong......
After months of waiting for parts, drinking beer and some work my Big started up "after half a turn". I was astonished.
5 minutes of pure joy and excitement followed <= this is the emoticon for this

Anyhow, i let it work for a minute or so, it was giving some dark smoke - ill check on that tomorrow, probably oil from repairs everywhere...

Some new parts:
New camshaft
New rockers
New valve seals
New balancer chain
New piston rings
Some bearings, bits and bobs, seals there n there, base and top gaskets
Carb float valves
K&N air filter upgrade
Exhaust sorted out

something else i'm pretty sure i forgot to mention.

Anyhow. i'm glad it works.

If the smoke remains tomorrow, I'll get worried and really upset, as this is my first bigger Big repair. Moreover if its gonna be blueish - im fucked, as new gaskets were used and it will mean that ... ah who cares, i'm celebrating today. I'm glad I managed to do this all by myself, only help I got was to measure the cylinder/piston/rings for wear and to look into the valve head.
I plan to get some pics ready, but they are really shameful (big was dirty) and irratic - it was hard to get pics done with greasy hands (plus Im using nokia, which takes 2 minutes to focus one shot).
Keep you posted.

Wundis, Things will have to bed in so take it easy on the throttle for a couple of takes of fuel , the rings need to wear in to to old bore.
I hope you used genuine Suzuki valve stem seels.
well done so far.

I will have to look into what I used for the internal sock part from them the memory is fading .

Thanks, Robo.

Wundis.....

Best way to seat new rings it to warm the engine until oil comes up to temp, then take it for a 10 minute ride. Go up through the gears using moderate to heavy throttle. Then use the engine to decelerate back down.

Don't hold high rpm or constant rpm.....just accelerate and decelerate. Being too gentle will not help the rings seat.

Let the engine cool a while then do this again.

Then change oil and filter.

Next do somewhat longer rides but don't do long droning stretches of motorway. Let the engine cool down after 20 min or so. You want heat/cool cycles. You want variable speeds to force the rings out against the bore but not holding one steady rpm. If it were me, I'd do another oil/filter change after about 100 miles or so.

There are lots of articles on new engine break-in.

AS for going up through the gears and up to the normal riding speeds its good.
some foam contacted to the side cover would help in front of the opening or similiar like Ray tried a bit of plastic from a bottle to cause a vacume to the opening.
Another thing that is worth a try Shane would be to drill some holes in front of the snorkel but leave the snorkle in and try, maybe the best of both worlds.
Thanks Rob. I use the bike daily at the moment and for the last two weeks and for several weeks to come this includes a trip up and back to my cousin's farm about 200 kms away. I've put a bigger case on the back and its great to take the tools up with and can go straight from road to farm laneways.

Bearing pullers

Hi guys,

I've got four bikes here, the newest being a VStar 650 from 2000. So now I'm thinking about things like wheel bearings, steering head bearings etc. Now I know I can use things like hammer and punch etc but I would like to use the tools that make it easier. What do you guys recommend for things like blind bearing puller sets, wheel bearing service sets, steering bearing race removal tool, and so forth.

Thanks,

Shane

http://trevorjordanmotorcycles.com.a...uki_search.php

glad i can buy starter bits individually. $1012 for a starter motor

Rob, i'm still waiting on brushes. this will be the deciding factor on whether i turn up on the on again, off again ride!

Great job Wundis nothing better than a machine you have built starting and running I put a camshaft and rockers in my 750 and had put plenty of oil around then when rebuilding, it smoked for a few minutes aswell but will be fine when the excess oil burns away . Just thought i would also post a link to a shop i got some heavy duty tyres from !! they have somw good stuff may be of interest

i'm confused now :/

it starts fine, works fine for 20 seconds, then starts to work like a hit n miss engine + black smoke out of the exhaust.

i've measured the float level with calipers - the lines are perfectly paralel, the level is at 14,7 mm. float level setup was made by following this link

i thought the k&n filter might be the faulty bit, but no - the stock filter does absolutely the same thing.

now when i measured the float level with the transparent hose the first time (carbs off, fuel in, tidy measurement taken) the results were +-0mm.
Now I checked the fuel level after I shut down the engine - i got surprising results, both floats were way up, like +7 mm up. how is that possible? if I bend the adjustment tab on the carbs to compensate for the +7mm , the lines won't be anywhere near parallel.

i somehow get a feeling that the new replacement needle floats (oem) have weak springs and are not able to hold up the floats in the middle point, vibration does its job and the small springs get pushed in, thus raising the floats and flooding the carbs = ergo the black smoke and shitty run.

guys, i'm stuck and i need advice. buying another set of needle valves is a true robbery. bringing back these - dont think it will work like that.
