got a set of 36mm - part dyna moded - set up on dyno for a std 1100L motor with a noisy exhaust and twin KN filters - if you want to play with them - see how it runs to help provide a bench mark - i'll not need them this yr given the pace my projects are not progressing so yir welcome for a "borrow"
-
i'll vouch for cam float on a gs1000 - observed as previously noted - move the bike from side stand to upright and it comes and goes - my foggy memory from a long time ago is - sounds like a random dull knock, where as a worn bucket has more of a consistent higher frequency rattle
-
MS006 with 55mm stack length is what I use - interesting discussions in this post, the question " can anyone show actual erosion / debris wear " running unfiltered - or effect of air entry restriction into the stack - can only offer my own experience I've observed screwing up the carburation by fitting tea strainers to stacks on 33mm mikuni smoothbores - possibly could have tuned it out but simply run without - great - run same set up with and crap I've not observed short term wear damage - forsure I'd presume long term accelerated wear but actually gauge this ? dunno - recon a wet carb left to let fuel creep into the head/bore probably causes more damage Erosion wear shouldn't be an issue, if I recall port flow is optimised at around half erosion velocity - ok there will be accelerated flow across valve seats as valves open which could cause wear but its not something i've observed Carbon build up that then gets displaced - clean air in - make micro deposits inside combustion chamber - rattle this about and flow it out the ex - the best filtered air ending up contaminated is std practise carbs! - big yes, erosion yes, sticking due to fine debris yes - basically filter for the benefit of the carbs - definitely yes free still air at stack entry coupled with smooth radioused entry ? this is not bike specific, this is common gas flow - laminar versus turbulent flow issues - and its back to the gas velocity for effect - the higher the velocity the greater chance of turbulence = pressure = less flow - valuable fine tuning stuff which may show only when up at the high flow demand - will have more effect if you run smaller ID / longer stacks - ok so more important on say 33mm carbs versus 38mm feeding the same engine - - basically this is inline with why a plenum or airbox

jees thats huge - thanks
-
interesting i'm also looking to extend a set of slabby 750 forks - what do you gain by fitting the power screen stanchions / thanks
-
most enjoyable to watch this develop, the F1 lurking in the background - now in process of going through this build post
-
pop in past huntly with the frame and i'll weld it up for yi - cost yi a 4 pack of rowies - 2 each - if you don't have transport I can pick it up next time up Elgin way
-
i'm probably miss reading the pic but it looks like you don't have steering lock stops ? - if not - you could add these to the oil cooler bracket design
-
that's daft cheap -long live china - a few cuts with a hacksaw and a half decent jubilee will clamp em up - if needed, probably when the thread for the grubs disappears
-
oilyspanner gets my vote - more ignition during part throttle / load via a programmable ignition - fitting a throttle position sensor ( easy these days) coupled with a crank position sensor ( or cam) - my experience with a 5 deg fixed advancer on a gsxr1100L motor - yes a bit more sparkle but no more than a touch leaner on the main jet - kinda like "dyno says X jet - bum says prefer a tad richer"
-
as your keen as mustard to get out there - suggest you give it a good spray over with ACF50 - will help to keep it as clean as it presently is
-
wow! - everything - you are creating something special there
-
imagination is free, however woman were invented when blokes sat on the fence toooo long for the ladies - no derogative intent intended
-
as said by all, dam't fine tribute and it possesses a touch of magic, looks like the carbs grew to match the inlet ports - mind passing on the engine build spec
-
i'm liking the whole set up- the adjustable offset and the way its pinned both top and bottom - thanks for posting the detail
-
one thing to watch out for on any older (used) bike engine ref: ignition is for any wear where the ignition rotor is pinned to the crank - any feel of movement before you nip up the bolt can easily cause a 5 deg shift on base timing value ( the pre set ignition advance is relative to the base value)
-
och yir just up the road - used to run and party with a few lads from Elgin area - mind that was back in the days when a GS1000 was main stream and a TS250 was for beginners i'm getting close with a project that will need a fresh paint - would you be interested
-
Scotland + got a great attitude with bikes + yi can paint - - gets a triple fae me - where in Scotland are you ps no laughing - got a lot of respect for those who give it a go - good on yi, even if its half baked its still better than a cheque book charlie
-
can't nail it - its kinda a cross between Dennis the Menace and a touch of the Papa Lazarou about it certainly got a look
-
what a breath of fresh air seeing folks doing / discussing proper stuff on a bike forum - I can imagine maybe 3 typical replies you would get on other ones 1) whats a sprocket or 2) ohh I wouldn't be doing that - all sorts of horrible things are going to happen if you do 3) cool - where can I also buy this cam timing you speak of
-
aye fond memories flat oot on a mates gs750 ( i'd just stepped up to a TS250) fook this things scary quick then another mate went past on his GS1000 sooo life's progress by passed the 750 enjoy yours
-
once you've got decent handling to your liking ( sounds like you do ) - on my list next would be a decent set of carbs - a set of smoothbores in replacement of CV,s - £400 marginal but should be enough to go fishing for 2nd hand set - good thing is you gain on immediate fitment plus they add to any future development - and they are cost recoverable when you come to sell on
-
without knowing your reasons why and what i'm in the johnr camp - if your not into track days - still focus handling and tyres - stuff for free is drop the forks 5 to 10mm, for not a lot adjustable dogbones to let you play with rear ride height, a 3 tooth larger rear sprocket to give you some free performance and if yir tyres are good then look for a half decent rear shock
-
aye Tony, the templates work when you know where your going and you can jig bend in 3D and replicate parts to an exact template when you have a curved cross brace that is going to miter into 3 different locations or your shaping tube by eye in 3D from a 2D paper template - a nibble here and a nibble there as you work the pipe in is the only way I can get it to work lacking the patience to design on paper, then build jigs to enable transfer of design into metal - i.e. think twice cut once - na, cut once, cut twice - scrap it and start again until it works
-
recently had same clash of brake with hub issue - got a disc made for not a lot that was 20 mm bigger OD - sorted ( using the gsxr 240mm disc hanger versus the 220mm ) only benefit i've found ref: eccentrics = handy rear ride height adjuster - quite handy but a bit of flaffing about with chains and sprocket selection to make it work
