Re: Motor Overhaul (summer project)
At WW No earlier when blaine said it cuts the rpm by half I thought he had a lowpro tire!
But with a 140/90-15 its a bit larger! Plus the 16T so I would say his RPM are what 450 or even 500 less on the highways? I wonder what 5th feels like around town! Login or Register to Remove Ads |

Re: Motor Overhaul (summer project)
3rd & 4th was excellent around town.Forget 5th.I wish I could change the gearing so easily on my 454,but it's belt drive.It comes with a 140/90-15 tire.I can go up to a 150/90-15.It don't help that it is basically a sport bike engine in a cruiser frame.At 60 mph it's revving right around 5500 rpm.But that's the nature of the beast.These little engines love to rev.

Re: Motor Overhaul (summer project)
if your using brand new pisto pin bearings i would go for it. i wanted to warn y about port and polishing. i belive that its bad for the carb'd vehicle due to reduced tubulance in the intake track. the air and fule wont full y mix. if i wer you i would do some research maybe go see a machinest and ask ther opinion

Thank you very much geezer I really do appreshiate it! I do not minde anyone chimeing in with anything they think might be helpful on this or any build. The worst you could do is post something wrong, I will be checking everything I wanna do with pros! I was considering one of two things for what your say geezer and belive you me I have considered that cuz even on PFI its the same thing, pretty much only derect injection is where it would help when PP, or forced induction. I would love to source out a 08 or 06 head cuz thats when they made the domechanges to get one more MPG outta the bike, (they ran hotter but since I ahve the oil cooler I fig. no big right) but anywho having two heads and doing the PP myself on one head while still riding the bike. So no cost or downtime for me and then I just switch them, and if its not that great I can always go back and switch them again. Two! I was gonna fab up a 'ramair' intake system on the bike and use those stu[ed little turbonotics things that they say inproves HP and MPG. Thats not why I would want one I want one to make the air swire around in my intake tubing cuz once I PP everything smooth I need something to help mix gas and air. Let me know what ya think :2tup: |

Re: Motor Overhaul (summer project)
wow dude you got it at all angles :2tup: still bottom line i would go see a performance engine builder and see. i happen to kno wthat those swerl things are a scam, they do nothing but act as a restriction. and once the so called "mixed air hits the carb it will go back to where it was and you still wont get the swerl you need for proper cumbustion. i actually went to school for 2 years on automotive and thats where i learned this stuff. if i were you i would make the intake and exhaust ports bigger, gasket match and 3 or if possible 5 angle valve job and thats where you will find more power. as i said if you think im full of it go see that engine builder.
someday ill have a GZ300 i cant wait to i plan on leaving the bke stock looking but getting new emblems made that say gz 300 instead of 250 that would be pretty cool
