hey guy thanks for being so patient . i know it has been a while since this post has been created . the motor is back in the quad now i'm going throught the breakin now and then i well have some numbers for you guys . The motor seems to have alot more toqure but wont know all the details until we tune it in on the dyno this weekend stay close
HEY GUY'S I have finally got a chance to rip the new motor and the power is great it seems to have a lot of toqure . I am having some issues with the rings sealing up right .but it does not seem to hurt the power I have taken some extra care to try help the rings seal up but they just dont want to . so I am wating to her from bcs if it would be ok to run on the dyno like that but they did do a great job porting the head it looked real nice and makes good power . I am hoping to see mid 50"s I have a customers bike here that dynod at 48 and this ones is alot faster I will keep you posted in the next few days
which piston and comp. did u go with...im in the middle of a rebuild myself.....went with the CP

QUOTE (kevinpowerski @ Oct 23 2008, 10:43 PM)I'd think it's gotta dyno mid 50s.....big 3 plus cams dyno's just under 50 (yes they are all diff I know the drill)...Sounds sweet for sure!
QUOTE (offroadhunter @ Oct 24 2008, 11:21 AM)I belive that jay used 14:8:1 cp but I will ask him to be certian.as for dyno numbers I have not ran it yet it is having some trouble sealing up the rings but not to worry it is just a small issue > I am super ready to dyno it .it should pull some good numbers the power is awesome and every where . jay at bcs did a good job on the head the web cams he uses are a real good cam .
Stupid question but how can you tell if the rings aren't sealing up right?

Well you can check comp and you can usally see blow by. I was not completely sure if that was it or not so I pulled it a part. I checked the valve seats and stem seals and put a new piston in. I have been waiting for parts from jay at BCS but they never showed up so I fixed my self and it is runninig great . I pulled 52 hp at 5,200 elevation With 34Hp base line I like the webb Cam shafts because it is between hot cams stage 2 and 3 . Bcs customer service was not very good for me but it is easy to make a mistake when buliding a motor . If you want to wait along time for your parts to arrive these are your guys . they did do a great job with my head and it make great power. thanks jay
