BANSHEE HP

You can't rebuild a stock basket, they use rivets instead of bolts

Yah I dont know whats wrong with posting links, I was able to with my phone but obviously its not like the link should be.

Almost to our goal of 100hp on gas. (not sure why the video links dont work but click the picture for the video)

Heli coil works just fine

29L was a vitos 110mm rod and plenty strong even with the big ends milled down... 29L/R is the wang 115mm long rod. When has any banshee rod besides the 29l/r gave ppl any problems? Even when the wang rods snapped in the middle, the big end of the rod was intact.

So whos in what site? I see 3 cabins and 6 sites reserved, lets put a list together and add to it as they get filled. Main reason is that last year some ass holes built a mini quad track next to my site, lit my picnic table of fire, kept me up all night with shitty music. So Im not looking to camp near them guys.

This was a stock stroke trail port we did on a bike a few months back. Stock head, 30oko, full air box, fmf fatty with spark arrestors. The green line was baseline, red and blue are after tuning. This is a stock 2006 yfz. Red is baseline Blue is air box lid removed, k&n filter with a pre-filter screen cover, the stock spark arrestor swapped for a vitos higher flow version. The dyno is a dyno jet 188. Basically the industry standard as far as chassis dynos go. WIth new a/f meter this year, new tower software the year before. It reads that same as many dynos around the country.

Blue- big bore shearer inframes Red- small bore oof shearer

Figure most shop rate are $75 per hour, so at least $75+ the $50 timing plate (if they don't charge $70 for it). Or for less than $20 you could buy a flywheel puller, $50 timing plate and be done in under a hour of your own time.

Or send your stock cylinders to us at Driveline performance. Our bore charge is $55 per hole. We can fix your problem one way or another, if only one side is really grooved up we can probably come up with a cylinder to replace it and bore that new cylinder and your other cylinder to the next smallest bore allowable

You see on the smaller bore cub they use the 795 piston. I know they don't make a 68mm 795 but it's what you would use if there were one. Either in zilla killas case we can do either piston.

Your correct they have it listed as the piston to use and with a .012 gasket. So just figure the cylinder is same height as stock but .008-.010" lower than stock with a .012" gasket, the rod is 5mm longer. A 573 is a 6mm offset, so the piston would be give or take .032" further in the hole at tdc. A very shallow stepped dome could be cut so the squish wasn't in the high .060s-.070"

Wsm makes a direct replacement piston for a long rod stock stroke. We can get those. Our pistons are a 6mm offset he needs a 5mm, like a 795 wiseco but in 68mm.

Dynoing Lanes 7mm bike right now... the first pulls are very promising

Neither was I but I've answered the same questions a more than once. Read the thread and look at the pitures.

All your questions have been answered in the posts before yours.

$375, raw unplated, no pistons.

They are low, 120-122*

^ he's got a $2500 engine

They're 30mm at 68 bore the triples are 29mm. 7mm cylinders are 32mm and 33mm triples. 189/190 exhaust on all the strokes as cast.

Were seeing high 70's low 80's and 45 ftlbs of tq from a 421 with 35mm carbs and cpi or shearer pipes with very little intake and exhaust work, other than adjusting the port heights to just under a cub as cast. While talking on the phone with someone today I had to explain how "as cast" is going to be only sold as un-plated cylinders. We wont be sending as cast to be plated, the cylinders we'll sell ourselves will all be ported to some degree. A port job, effectively a "dune" port job will replicated on the cylinders that we have plated and will sell as bolt on kits with our pistons and domes etc. We can at the time of purchase port your cylinders to however you like for an additional cost. Another question I was getting was whether or not there were room for "boost ports"? Today I figured that out. This is the result of about a hour and a half figure out where to drill and how to start them to a ported finished product. Builders that are handy with porting tools like Cam said should really shine with these.

You can't please everyone with one style of porting. Everyone ports and sets up engines different and obviously you can't grow back metal. The 4mm can come in port timing like a serval or cub, since 7 and 10mm strokes are not as likely to be bought as a bolt on setup and more likely to be a full port job to a builders specs they are as cast low port timing. Making changes to the outside casting was going to be quite a bit of money in addition to just purchasing it. In the future that inside pocket will be filled in. And there is a transfer port cnc program in the works to open the transfers with out doing it the hard way by hand.

Order and pay for them and we'll make them... pass it along.

65mm is as small as possible

Was a good time saw some good racing, the rain stayed away and it was a good 10* cooler with some wind coming of the lake huron.
