Dunno how long for tho as youll go through the hardening. annoyingly twin cam but interested to increase lift etc wouldn i have to lengthen the lobe? or does hacking away the sides of the lobe do that? once ive had my fun with it ill give it away so not worried abotu fucking it Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 19, 2008 Share Posted February 19, 2008 yea some weld them up to increase lift, most will reduce the base circle and run bigger shims. To do this accurately with an angle grinder you would have to be a robot. You wont get any gains if it even runs at all Quote Link to comment Share on other sites More sharing options...
QCADTA Posted February 19, 2008 Share Posted February 19, 2008 No expert but wouldnt grinding the sides out reduce the duration? crazy idea but hey, go for your life and prove us wrong. Quote Link to comment Share on other sites More sharing options...

TYPICALLY HOW MUCH METAL WOULD ONE STICK ON? FEW MILL? Quote Link to comment Share on other sites More sharing options...

Guest vvega Posted February 19, 2008 Share Posted February 19, 2008 used to do it with single cylander go cart motors you reduce teh base diameter by 3mm then take 2mm off the lobe tip that gives you 1mm more lift and a fuckload more duration only did it with rocker motors and single cylander....easy to match it Quote Link to comment Share on other sites More sharing options...

sentra Posted February 19, 2008 Share Posted February 19, 2008 could you do something like build open side of the cam up 10mm, ressemble the head , clay the pistons then grind the lobes back (in place) untill they all have the same clearance. take the cam back out and clean up the ramp? 1 Quote Link to comment Share on other sites More sharing options...
Guest vvega Posted February 19, 2008 Share Posted February 19, 2008 ffs its not that hard you get yourself a dam micrometer grind the base down to a measurement that is referanced off the lob once you have all of them to .01 mm you then do the same to the lob top measring off the newbase circle finish teh curves etc with a linisher then polish then once done useing a carboprising flame on a ocy asetilene plant flame harden teh wearing faces ajust shims and done Quote Link to comment Share on other sites More sharing options...

Mike-e Posted February 19, 2008 Share Posted February 19, 2008 if your silly enough to ask how to do it for gains and not know before hand you wont get any gains even if it magically started again and if its not about the gains and about amusing yourself then shit me, fuck us and just go and do it. scooter/fatchick analogy springs to mind Quote Link to comment Share on other sites More sharing options...

zep Posted February 19, 2008 Share Posted February 19, 2008 Also, record car running before and afterward so we can heard how lumpy they gots. Quote Link to comment Share on other sites More sharing options...
arsnik Posted February 19, 2008 Author Share Posted February 19, 2008 HOW MUCH METAL SHOULD I SPEW ON IT? massive lift ftw just throw about a cm on and work with that. I saw chip foose do it, so it must work. Will work with ~10mm theory Engines already out its teh spare bike (oldschool as!) but have a complete running other one to compare it to. If it ever goes again will take some vid/sound footage There are shit cv carbs that never seal proper on it to. 8 lobes to fuck with = lots of fun theres no way an angle grinder and a welder will get to .01 mil but will get lumpy Quote Link to comment Share on other sites More sharing options...
