After looking through countless forums for jetting advise for a 1040cc draw through turbo setup im doing. I found a few mentions of the 2.3 float needle being a must. I ordered all sudco had to offer for float needles left to right (2.3,4.2,4.5) and the 2.3 was by far the smallest of the bunch which leaves me scratching my head a bit. Is there some kind of regulating effect the 2.3 gives with a fuel pump that makes it viable? Seems like the most counterintuitive solution and i'd really want to install the 4.5 float seat which has the biggest hole. Keep in mind that the needles themselves are the same between the bunch I checked that already

This engine won't see more then 11,000 rpm I suspect. The cams are stock as well so it definitely has enough spring. I was just thinking from a strength standpoint but the decreased weight makes sense as an advantage. What are you guys running for head/base gasket sealents? I'm running an o-ringed block with a copper headgasket as well as an aluminum base plate and caught between a few solutions recommended by friends. I was recommended permatex copper spray, threebond 1207b, or gasgacinch so far. I'm leaning toward threebond 1207b for the headgasket and gasgainch for the base plate though I heard gasgacinch is good for headgaskets as well. Any thoughts?

Draw through manifolds have the boxy shape because of the lack of space as well. Not to mention you want the fuel to stay suspended in the air which becomes harder the longer the intake track is. I'd be interested to learn the effects of a split plane draw-through intake vesus single plane. The old ATP kits usually had a split plane just at the inlet whereas the Mr.Turbo manifolds were generally single plane all the way through.

Draw through setups really died out when fuel injection came into play. There are very few draw-through turbo's made today especially to fit a 750cc engine. Though there are older solutions that would work quite well namely the Rajay's. A Rajay B25 would be what you want they are good for engines up to 1000cc and can efficiently flow up to 20lbs. I have one off a running bike if you decide to go down this route it's an ATP badged unit as well which are hens teeth these days. An HSR42 or a Super B/E would suit the setup well. Either can be setup and work quite well just try to avoid the Bendix carbs if you decide to go with an older style setup they make the bike a chore to ride on the streets.

No Class- Clutch basket currently is out, so oil pump isn't currently spinning with the drive-train. I'm going to chock it up to reusing the oil seal on the counter-shaft(09285-20006 part number) and deforming it a bit when pulling it off/reinstalling. The transmission spins smoothly once it's moving just a bit of resistance to get it spinning. I appreciate the quick response. sorry to repeat the question but does anyone on the forum have experience using stock retainers with heavy duty APE valve springs? Most likely will keep the stock retainers just curious to hear of any horror stories associated with them. Currently waiting for the cylinder to get back from the machine shop, barrels are already bored for the busa slugs but i'm having the block o-ringed using stainless wire. I told the machine shop to aim for 0.006inch raised off the deck which is about 15% of the copper gasket's 0.043 inch thickness.

Cheers mate thanks for welcoming me onto the forum. Just finishing up the shortblock for my turbo bandit 1216 build. Upon getting the shortblock together and all torqued to spec I noticed the transmission has a bit of resistance when turning. The final drive shaft spins freely with play but the shaft the clutch basket runs off spins with a bit of resistance. I'm curious if this is just normal or something to be concerned about I rebuilt the transmission entirely as my previous 3rd gear had voids in the casting near the end of a tooth or two. Also just got the head squared away, lapped all the valves and put new seals in as well. Also put in APE heavy duty springs. The stock retainers are a bit thin are they up to the task?
