Lunchbox and Jetting, Quick questions!

[Jayke]

Ah right that's cool then, figured black, carbon, rich. Haha that's my judgement. And no not yet, I think Tuesday I will be taking a look at them. Gonna bring out all the stops on that damn screw . Although I might actually do it now. 6pm may be a tad late. Would you recommend using the bleed screws to get the fuel out even though I'm only checking needles?

If you're leaving the carbs on the bike, then there's no issue with leaving the fuel in the bowls.  If you're pulling the carbs or removing the float bowls, then you need to drain the bowls.

But yeah light black soot is perfectly fine; heavy dark black soot is rich.

Right got it all back together with no fuel leaks
Got it running to a nice temp but found the tickover was a touch low so adjusted it to around 1200 rpm and it ticked over perfectly  .
Took it for an 80 mile blast with my mate and everything is fine. Its pulling hard in every gear from stand still to red line
So all is well few issues such as not setting the throttle cables correctly and having a bit to much play but i can sort that whenever and my clutch needs adjusting but thats nuthin to do
with what ive done  just basic maintenance.
So my set up is :- 20/65/147.5 , 3 turns out on mixture screws , needles raised by moving e clip down one notch , idle screw adjusted half a turn.
05 gs500 fitted with delkavic full stainless system with k n lunchbox , k n free flow oil filter , castrol 4t power 1 racing oil
And ngk iridium spark plugs.

Ps lunchbox sound evil on full chat lol

[Jayke]

Thank you rado, looks like it will most likely be Tuesday I mess around with it.

And great to hear crasm, will have to order myself a 65 soon, although not too many problems with the 62.5, but better to go with a known working setup ;p.

How about top speed, did you test it? How about the pull after 60-70, mine feels pretty dull, won't go past 80, although there was an almighty headwind, so that wouldn't of helped!

If im being picky i might turn out the miture screw by half a turn to  3.5 turns just to see what happens but other than that i am chuffed with it!!

Jayke - was on national speed limit public roads so only  went up to 70mph     . . . . But it got there very well

Find a spot without cops or speed cameras 

Around here the speed limit is 70MPH as well; the stock jetting got to 95 MPH just fine, but slower acceleration after 65MPH.  Rejetted with stock pipe got there a lot quicker.  New pipe and upgraded jetting has a lot more bark to it and feels a bit more powerful in town; haven't really tested it on the freeway yet.

95 mph on private land / road right?? Your certainly not imploying you break the speed limits on public roads on an open to anyone forum are you??        

[Janx101]

lol yeah +1 on that !! ... all testing should be done on a empty road when no one is watching ... errr... trackday session or drag strip ... which is what i do everytime!!!! 

[radodrill]

TBH, only on 2 occasions have I had the bike that fast; I mainly keep pace with the rest of the traffic.

And all the testing can be done within the speed limit; just use a lower gear  and best during low traffic times.

[Jayke]

Well if you get chance see how the pull is at around 70, mine is none existent pretty much lol!

Just be safe when you do, in the meantime, I'm gonna order 2 65 mid mains and on Tuesday I'm going to do the needle.

Hope all goes well and I finally have a bike that runs as intended lol! - This bike has been nothing but trouble since I've had it, anyone who doesn't know/hasn't read my other topics, the previous owner did a 'full restore/rebuild' which by what I think means messed with everything from the ground up, with 0 knowledge. Even less than me lol!


Getting there though!!

At least one thing he didn't mess with ... The carbs.  Although, the screws were probably in so tight that he gave up 

And looking back, I've read all your previous threads; even the one that turned into a flame war about gas even so I tried to steer it back on topic 

[Jayke]

Very true lol! Contacted motocarb this morning, they already shipped my 65 jets out on next day delivery, fantastic!

Kinda off topic: is there any way to make sure the back wheel is aligned correctly? I've seen a video where they used a laser tool to do it, but I don't have that. Surely there's a ghetto way to do it, though! Any ideas?

The idea is to have you front and rear sprockets lined up.  There are a number of ways to do that, and ways that existed long before a laser tool lol.  Laser tool is probably the best, and most precise way, but isn't necessary. 
Some people just count the threads on the end of your chain adjusters that stick out of the rear of the swing arm.  That can be very close, and a way I would recommend to others along with checking it out by eye that it looks correctly aligned too.  Some people just eyeball the sprockets from the rear of the bike, others aid that with a string.  There is a tool made by motion pro that clamps onto the rear sprocket and has a little rod that sticks up to help align it with the front sprocket = eyeball aid... Some will do all of the above.  There's probably more ways out there too.  It is important to have good sprocket alignment and it will save you a bunch in chain/sprocket wear, but try not to make it into a rocket science.

Could you not just use the notches in the swing arm ?

After riding mine in stop start  traffic today ive noticed at pull off with very low rpm and slipping the clutch that its a little hesitant before 1500 rpm but totally fine all through the rest of rhe rev range  is this just the pilot not getting enough fuel?? Would say another half turn out of the mixture screw work?? Im at 3 turns cuerently so adjusting it to 3.5 turns out?  or would i need to step up to a 22.5 pilot jet??

[gsJack]

After aligning wheel using marks on swing arm, or amount screws stick out, or just eyeballing it, I check it with my metal yard stick. I lay the yardstick across the rear tire with extra length forward just below the chain and look down to see if chain and yardstick are exactly parallel.  If not fine tune the adjustment.  I turn wheel a couple times checking to eliminate possible tire irregularities.

I only check wheel alignment when putting on a new chain and don't disturb it between chains.  Chain adjustments are made by taking equal turns on the adjusters a half turn at a time.  Wheel can be removed for tire replacement without disturbing wheel alignment adjusters by hanging chain aside over the swing arm.

Meh.. the plate and notches are OKAY, but they aren't by any means exact... There is just enough play on the plates, that I'd employ several of the above methods in addition to using those.

Notches on the swing arm can be used but are discounted by many because the free play in the index plate has a lot of slop that can throw you off.  I did it that way for a long time before checking with the yardstick by carefully eliminating the free play and it worked out well.

With chain still loose snug down the axle nut a bit so nothing else is loose and put a block of wood under the swing arm from behind up against the bent over edge of the index plate and tap forward on both sides of swing arm.  That will rotate left plate clockwise and right side plate counterclockwise and make the adjustment readings quite accurate.  Keep everything snugged down until chain adjustment is complete and axle nut tightened.

Currently I'm at 4 turns with a 22.5 pilot    Buddha says they can safely be set up to 5 or so turns without the risk of them coming loose.  But I may get a 25 and try that out

[Jayke]

I noticed that too crasm, asif the revs  are kinda spluttering in way. Asked a friend and he said it was normal,  don't know about that, though!

Thanks for suggestions by the way guys. Much appreciated :p

I no what you mean about the index plates theres stupid amount of play in them. I was playing with the idea to see if other bikes index plates fitted better than the crappy gs's.

Radodrill - 4 turns on a 22.5 pilot? Bloody hell !!
Saying that my bike was 4 turns out on standard jetting so might give 4 turns out a try
When i get 5 mins , still got to reset throttle cables and adjust the free play in my clutch leaver so might do it all next weekend
