banshee9090 Posted June 26, 2011 Report Posted June 26, 2011 (edited) some of you guys would ask me, is there a specific reason for using stock cylinders and a 10 mil now a days There are so many aftermarket alternatives that are cheaper, easier and more efficient I would tell you yes sear , first of all, I m doing this not just as a project to see what I can do the things is I want to learn something some other reason I think most of aftermarket are nikasil excepted twister cyli. if nikasil replated required in the Future , no one in my place can replated if I send it to US it is a lot of money again . One more reason i want to use the parts witch I have it like cool head ,stock cylinders pistons because I think not good idea to throw these parts and buy aftermarket , if I trying to sell it no one in my place will buy these part from me, also I want to feel proud with you again the same what we did with 4mil home project last year, now let me tell you what I m doing, hear we go I resleeve motors with with wsm Heavy Duty 64 -69.5 , the sleeve come up past the deck height 1.3mm just to cover the piston rings, with tow stock base gasket used and a head dooms 22cc machined to accept the piston bore size 66.5 the squish is 0.7mm (0.025)!! if my degrees wheel I download it from inter net is correct I got, blowdown 30.5* -32.5* when the piston rings open exh 201 , there is tow transfer one is 140* the other on is 136* the top ports been not touch yet all I did I matched the bottom of the ports with piston BDC I have run the bike in idle with stock carb, 320 main jet elevation 2000, temp.38c seems to me not bad, but What I notes the crank compression 1s 202.5-203 psi witch not recommended for pump gas 95, I would like to ask your assistant, if the squish would be 0.050-0.060 could that low the compression or I have to buy dooms 23cc 24cc if there is any idea to modify the 22cc dooms angle to low that comp. What did I miss? guys help would be grateful Edited June 26, 2011 by MattSCESC Text was too small. Quote

What did I miss? guys help would be grateful I made the font bigger for everyone's sake. Um.... the pump 95 gas here in Saudi is close to 91-92 in the USA. I know, Im from USA, and I had to retune my Camaro due to the crappy Octane of the so called premium gas here. Sounds like an interesting build. I think most people recommend around 21CC domes on pump gas 91-92? Anyways, Im no Banshee motor expert, I just wanted everyone to understand that your 95 gas is a LOT different than 95 in the US. Good luck, and keep us posted with your results. Quote

RadarRacing Posted June 26, 2011 Report Posted June 26, 2011 IMO before you lowered the bottom of all of the ports you had room to lower the cylinders down to get your durations down to approximately 130 degrees. That is assuming the rings did not go above the sleeve. With transfers of 140 degrees your motor will not rev like it could and should. Depending on which pipe you are using with even transfers as high as 134 degres of transfer duration most motors will not pull up top at all. There would be ways to change your pipe and dome to compensate a little but at 140 degrees you are way off. As far as your dome and compression you will need to add about 4 more CCs to get down to pump gas compression on a 10 mil if you have over 200 lbs of comp. I do admire you for trying to build your own motor and trying something new. If you need the exact amount you would need to drop your cylinders to get down to 128 degrees of transfer durations I can calculate it on my other computer. Quote
banshee9090 Posted June 26, 2011 Author Report Posted June 26, 2011 that is one of things i would try to know ! Sounds cool, but your going to use stock carbs on a ported 10mil? Quote
banshee9090 Posted June 26, 2011 Author Report Posted June 26, 2011 sound good but i can not lower the cylinder even 0.1mm the rings will go out, i think my degree wheel is not slandered i will buy good one and check again, i would ask you what do you mean by ( to add about 4 more CCs) IMO before you lowered the bottom of all of the ports you had room to lower the cylinders down to get your durations down to approximately 130 degrees.

banshee9090 Posted July 4, 2011 Author Report Posted July 4, 2011 well i drop the compression from 200-210 to 158 -160 as per pic the doom has machined to and measured 24 cc i use water to measure how many cc the other doom, is 22cc and the last pic is stuck cool head see the different ! this pic of doom give 158-160 psi stock cool head this doom give 200-210 psi ,do you think guys 158-160 psi OK for pump gas with 2000 ft. elev. ? Quote
LS3 Machine Posted July 4, 2011 Report Posted July 4, 2011 I think 158-160 might be a little high. The pump gas here in Saudi is not very good. Quote
banshee9090 Posted July 4, 2011 Author Report Posted July 4, 2011 I think 158-160 might be a little high. The pump gas here in Saudi is not very good. thanks man that is the same what i m thinking , i will tray to drop it to 140-150. Quote
banshee9090 Posted July 4, 2011 Author Report Posted July 4, 2011 thanks man that is the same what i m thinking , i will tray to drop it to 140-150. alright guys , after break off i got 150-155 psi, do you think it OK for pump gas in Saudi Arabia ? the next work is chamfering the ports, i will show you photos for my project later on, thanks for you guys .

Paulie B Posted July 7, 2011 Report Posted July 7, 2011 Don't know if you thought about this yet but have you taken steps to keep it cool? 66.5mm jugs don't leave much for heat transfer. Outside of that I'd love to rock a 10mil stock cylinder bike Quote

Outside of that I'd love to rock a 10mil stock cylinder bike sorry for late, so far the bike is under observation i would keep an eye on that, i will see if i need to upgrade the cooling system and playing with timing plate or else i will rebore to 68 if needed what you would think is that make sense ?
