Yes but then no one seems to worry about that anyway and that why everyone is buying big bores. If people were really concerned about building an engine technically right we would all have strokers with smaller bores to allow for max transfer port volume. The good side about a big bore is you...

Are you adjusting the low speed mixture screw or the low speed jet. It sounds to me that your trying to compensate for to big a low speed jet\ two low a pop off pressure by turning in the idle mixture screw. Try fitting a smaller low speed jet and then you will be able to feed more idle mixture...

Yes you will need to match port the sleeve/ sleeves Good news on the welding , sort of a win there. I am sure the new cylinder tat team scream are doing are 900cc, may be best to send a message to chuckie on that. The advantage of going bigger sleeve is it will clean up any damage after its been...

If you pull the cylinder off and send it to ajsp I have some one up here who should be able to weld it for you

I'm with you . Same results. Frustrating as all hell

You should be able to get that welded up no issues at all. Just need some machining afterwards. You will have to clean up the ports where the weld / damage has hurt them as well. Might be the right time to put in there bigger bore sleeves they make. Im not sure of the damage to the cases but...

Oh and I wouldn't go over 5mm with the stock cylinders if I was you

I would look at buying a stroker crank If i was you. Much easier and cheaper in the long run

Seeya soon, Lukes a top guy you will have fun riding with him.

Sea world on the gold coast

I used to kneel when I first started to. hahaha He makes it look so easy

He is riding rickter hulls at the moment

Pickup a stator and a ignition coil while your there

Yes its worth while doing. you will not get a massive gain but you will get a gain

I dont see what I am running really makes a difference but since you asked. Yes I was running a 8mm dasa but I sold it and put in one of my ported stock cylinder surf port jobs. That way I can demonstrate it to my customers before they buy an engine off me. I only bash the crap products gil.

Agree with that , but as long as its got repeatability that one dyno can be used to measure alot of engines on the same day. Its when you try to measure different engines on different dynos its of limited use. If you have a look every one is talking about a dyno testing day for all engines. I...

Yeah it would be a great way to do it, figures on the dyno. Then all in the same hull for a riders impression. Awesome way to get real world info for prospective buyers. Having that info can only help push us further forward in development to get the most out of the engines. I would be right...

I will correct anyone who writes stupid comments in a thread I am active in. I have also commented alot of times on how good you cad work is.If you look for the negative you will find it however Just because you can draw a part on cad does not make you an engine tuner. It clearly doesnt make you...

Try and get the ones from the 5mm cylinders you sell with 8mm port timing in them. you can lift ports up. kinda hard to port them down

Great skills there Numbers do sell engines, have a look around at all the car advertising you see on tv. they are always talking more power. watch top gear the hp is the first quoted figure. Im sure they have very smart marketing people working for these firms The facts are there has been so...
