Stop guessing and get it setup on a Dyno.

Or just let gearing comander work it out for you

What do you mean back cut valves?

Because I have loads of power

It would definately help. Although I am living proof enough horsepower does make up for a lack of talent.

Looks to me that you can see on piston 2 where valves have been hitting it

Beat me to it.

Dont believe everything google tells you. The power figures quoted back in those days were wildly optimistic at best. Everywhere got the same spec engine and if anything the US were lower powered sometimes because of extra emissions stuff. My point was whenever you look at Dyno figures they generally seem to give higher readings for the same spec of bike in the US for sone reason, possibly using different correction factors or crank figures. Its not like theres some hidden magic tuning secrets the UK doesnt know about. Not that it matters, its just a number on a bit of paper

What base fuel pressure are you running? Also worth setting tge floats to 16mm. Worth trying to run the bike with gravity fed fuel, will show whether its fuel pressure related or a carb issue

That explains it, they are Merican horses, always seem to need 20/30 more of them than in the UK for the same spec of motor.

Your mechanic sound extremely optimistic, or talking crank figures.

Google gearing comander Put all the details in, and play about with sprocket sizes. Will give you all the info you need

General consensus is dynojet needles are a pain in the arse for turbo use, best off sticking to standard. You probably could get them to work but would take way more dyno time than setting up using standard ones

Dunno about motogadget stuff other than hearing its good. Ignition wise i highly reccomend Ignitech TCIP4 full versions. Fully programable and have loads of other features like shift light, quickshifter capability, start limiter etc. Pretty cheap too Give me a shout if you want any more info. I get a really good discount, have got them for lots off OSS people previously.

They do work on pressure. Thats what a vaccum is, a difference in pressure between different parts of the airflow

If they are gsxr 36's you want to get the propper shorter plastic tops, using the bandit ones is a bad idea, the slides open too far and apart from messing the fueling up, the needles can come out of the tubes and jam on the way back down. Gsxr tops on bandit carbs stops the slides opening fully too. Need to have the right tops for your carbs, had the same myself before and found out whilst on dyno luckily, not on road

Why would I be constantly turning it off and on, i have a pretty constant feed to my turbo with a matched constant scavenge. Electric pump loke I use only have one speed, ON, thats its design, and its,warranted to operate in its on condition, your implying "flat out" running isxin some way goimg to affect its reliability, it doesnt, its just working as intended. Much like electric pumps used in billions of applications the world over

Electric pump doesnt have flat out, just on or off, exactly what its designed to do. Engine rpm is largely irrelevant, turbo gets pretty much the same oil flow through it all the time, just a case of matching your oil in to what the pump is taking away. Imo thats easier to do when your not having to deal with constantly varying pump speeds

What Ive never understood with these pumps is how you get around the fact they are constantly changing the volume they are scavenging. Turbo is getting a relatively steady flow of oil through it and needs a pretty constant rate of scavenge. These vary massively with rpm, way I see it thats not going to work properly either at lower rpms or higher, either not scavenging fast enough or too much and sucking turbo dry. Realise loads of people run them but personally I will stick with a simple electric facet pump

Will get those cases dug out for you and hopefully make trip up when we are allowed. Might need my bits back off motor too, going to start getting my slingy together

Looking good mate. Glady your doing something different with it

Ive got a little bailey dump valve on mine, and you can hear that going off a bit at slower speeds anf mid revs, not a huge noise but its reassuring to know its working as it should

Nope, prefered to have a brief moment of smoke on startup to let me know o had oil to the turbo

100 size mikuni main jet i ended up with

If I was building a propper race bike I wouldnt want to use one without a fair bit of bracing. But for what they are, and how they are mainly used they are great, did a track day on mine and it worked well enough in much the same way a bandit does.
