can you post some pics?

Chris, is the roof of the rear boost port at the same height or lower than the transfers? Thanks again. What's your paypal address, so I can send the $$$ over and you can then ship the cylinders today.

I'm really interested too. Can I see some pics?

ok, exh and transfers are ok, but what about the boost port? as long as the roof is lower than the transfers, we're good to go. do you take paypal? would you do $200 shipped? i called you this morning, but no answer. i did leave a message. did you get it?

I will give you a call around 10 or 11am. Thanks chris.

ok, i'm really interested. can you take some measurements for me tho? what is the measurement from cylinder deck to the roof of the exh, main trans, sec trans, and boost port? i want to see if the timings are outta league for me etc. also, the bore is totally ok to run? also, if i buy them and they show up not as advertised or they won't work for me, would you refund? thanks.

do the pistons come w/the cylinders for $200? thanks.

i still get a kick outta guys that think compression testers are what's used to determine the octane needed for a motor. you need to compare total volume in cylinder (full stroke volume + deck height volume + head volume, which is all volume above the piston, when its @ BDC) to the trapped volume (all volume above piston @ TDC) to determine octane required. there's a few more little factors, but that's the main one.

depends how much you shave and what the new UCCR is. you could shave only .010" and have UCCR go up to "here", or cut .040" and have the UCCR go "HERE". know what i'm saying?

cool, i probably order a set up then. thanks for the feedback. they fit just fine in the stock intake boots and airbox boots?

so, how did those carbs perform for you? i found some on ebay as well, and was interested in buying a set too. just wondering how well they work, before i spend the money.

If its deto, it will show itself on the domes and piston crown. The domes will have all these little specs/pick marks on the squish band face. It will also appear to be sandblasted.

tim, if it were my choice, i would run the forged wsm's w/the added boost port. just my .02

depends on what your are doing w/this atv......woods riding, dune riding, etc. can you put up w/a little less bottom end, but way stronger top end, or would you rather keep as much of the bottom end and have a mild mid-top gain? that's up to you. i know when we put tm28 mikuni flatslides on my buds shee this summer, i noticed a bottom end loss. i kinda didn't care for it at first, but when i got used to it, then it wasn't bad.

yeah, i would like to see those pics larger. is that some sort of jig, for your 90deg handpiece? pretty cool. looks like you got good lighting in your work area.

IMO, i think you'll notice a bottom end loss, w/the 30mm carbs, raised exh port, and lower compression, that only requires 93 pump gas. but it will rock from mid-top.

i ran your numbers tim lutz and here is what i got..... exh 187.44* main and sec trans 122.3* boost 110.8* 32.57* blow down ***this is assuming a .4mm deck height*** it should run pretty fair/strong for you. if you raise your main transfers up another .5mm, it will change the main transfer duration to 125.03* and blow down to 31.2*....IMO if you go this route, at least raise the boost port to 43.5mm from deck and that will give you 119.52* duration. i have always loved this .5mm staggered port setup.

When I get home in a little while, I will run your port heights in my software and see what durations you are at now. I personally like the staggered porting. Right now my main and secondarys open at the same time and my boost next. My shee is 188* exh, and 124* transfers, giving me 32* blow down and the boost I think is now at 118* duration. When I pull my cylinders off again, I'm going to raise my exh port, to give me 190* duration and I'll raise my main transfer only and enough to hold 32* blow down. That area of the secondary transfers that you are talking about, is what's called the "hook". Depending on how sharp the "hook" is, it will depend how the charge is aimed and where it will end up. Rule of thumb is that a sharp hook that aims towards the exhaust port is for top end and ones that are not so sharply hooked are more for bottom-mid.

Awesome!! I give two thumbs up, for giving a TRUE accurate description of octane boosters. Finally someone gave the real low down on octane boosters.

Hey Tim Lutz, if Brandon @ Mull Engineering is busy or whatever, I got a guy in Oregon you could send your head to. Contact me if you want his info.

A +4mill stroker is the smallest stroker kit available. Nobody makes a +2mil stroker crank for a banshee.

sorry, i didn't see that. thanks again tho.

What ever happened to the pics you were going to send me of the cylinders?

Snope, I'm assuming that DG bumper is gone? I never heard back from you.
