[how wide is bandit swing arm]

cheers guys so a gs thou is about 225 so its 5mm to make up :-) just measured a busa and thats abit more than 225 so some to loose :-)

thanx chaps

[how wide is bandit swing arm]

aye up all quick question how wide is the bandit arm at frame ?

cheers

[swing arms are like the bus]

got a couple of lm shock links along with allsorts of bones etc :-)

[busa rods/pistons yeah again :-)]

yep mate the way forward haha

[busa rods/pistons yeah again :-)]

yeah will do , just confusing people say differing things hmm cheers again chaps got all bits so ill pop in shed and use an old 1216 1127 set of mullered barrels to get a look at this whole spacer issue haha

[busa rods/pistons yeah again :-)]

if so then the spacer will be needed as the gen 1 rods are longer :-)

[busa rods/pistons yeah again :-)]

hmm so thats standard rods with busa pistons ? no other alteration to barrells ,

Be cautious just using gasket to determine squish. An uncompressed gasket maybe 1mm? but when compressed 0.5mm? but recommended safe squish is about 1mm (allows for rod stretch / avoidance of pre ignition) - some race engine builders go as tight as 0.5mm but really not advisable) So ideally you need the piston to be 0.5mm below deck height and allowing compressed gasket.

Busa piston with dish compared to std. GSXR piston with raised crown makes big difference in CR.

cheers guys :-) soooo what im gathering from here is that 1mm squish on a fully built torqued down motor is good ? no problem with valve to piston clearance ? will do a full plasigauge test on a dry motor but im looking 1mm down to max .5 , its not being built to comute to work so just for fun and ive noticed the spacers do come in varieying thickness if needed , getting some good feedback on this much thanks lads :-)

[busa rods/pistons yeah again :-)]

and your also saying that correct squish is roughly the thickness of a gasket hmm barrels back and lets see , my calcs should put the piston more or less flush with top of barrells with no spacer so nowhere near 2mm i rekon :-) cheers matey

[busa rods/pistons yeah again :-)]

so what were saying is the actual shape of the gen 1 piston ( dished ) reduces the compression even when at correct squish ? so if running na the extra cc,s are at cost of compression right :-)

busa rods are stronger than std gsf/ gsxr rods.... usualy a choice made by the builder when a turbo or n20 is on the menu .  dropping the pistons on the std rods will net you low 8’s on the comp figures.... not really a performance upgrade if going NA .... 

yeah i get this but the busa  rod is roughly the same difference as the piston difference so should cancel each other out the only reason i see from fitting a spacer with both gen 1 rods and pistons is to drop compression which i dont want :-)

You'll need a spacer as with the longer rods the pistons pop out of the barrels - though that would be obvious?

so why use busa rods why dont i just keep the standard ?

[busa rods/pistons yeah again :-)]

waiting for the barrels to come back and dry build it is :-)  ( still carnt see the point of a spacer ) surely someone has done this !!!

 

[busa rods/pistons yeah again :-)]

aye up all got all the bits to do the yorkshire ( tight twat ) 1216 this time , im sick of being told differing on the spacer !! piston is shorter lower comp for turbo on standard rods but im running n/a so got the longer gen 1 rods so why are people saying i need a 2 mill ish spacer ? that in my eyes takes away the point in putting longer rods in ? pardon me if this a thick question or has been answered many times before :-)

[mistral head]

yeah i got in touch with em , well the people who where them stock valves but flowed , were supposed to be the top guys in the time , cheers

 

[mistral head]

aye up all picked up an 1127 head in a deal with lots of other bits bottom end etc a while back , the head had mistral gas written on the side in white marker , thought nowt much of it has had alot going on at the time but then decided to check up on it , has been worked defo contacted mistral they said as it was just a head they had no way of checking back on there records but did say it could have been them , just wondering if any one had any ideas of how to check valves normal size i think carnt remember will check in a bit and take some piks if anyone can help cheers

[frame id stamp]

No not yet like you say the symbols look Japanese and are symbols not numbers don' know no other I'd visible on frame

does this type of frame stamp mean anything to anyone ? cheers

[srad rear wheel in boiler swing arm]

Haha but why me my engine is oil cooled I feel like !!!!!! Well I feel hurt 

[oil or water]

But at what temp does oil boil hmmm

[oil or water]

Yeah like that hahaha 

[oil or water]

right so at what point does my turn from an oil burner to a water boiler !!!!! the heart of the machine is an 1127 m series but !!!!! yeah this is the one the frame is wp wheels etc srad i would think that i,m still oil but who knows what the mongrel will take after hahaha
