how about jeffs porting


Recommended Posts

Well first off you should call Jeff and talk to him about his work. But I have never heard anything bad about his work, nor his reputation. A lot of people will chime in shortly that have had port work done by him. He's buildin' me a Cub right now , so I only need a clean-up port, and I trust him 100%. Talk to Loco, dajogejr, and a few others they will hook you up on the referrals................ :beer:

Jeff reccomended me a dune port when I called and talked to him.

I have yet to recieve my ported cylinders from him, but they are supposed

to be pretty strong. Call him up and talk to him. He's pretty cool to talk to

and can give you all sorts of insite.

PM Gripperz, he's got a dune ported motor and he said it screams.

I had Jeff build me a complete 4 mil, 35pwk, and his dune port, He said he did an agressive dune port due to the way I ride( fast trails and dirt roads ). He also ported the cases. I run cpi inframe drag. So all in a nut shell it gets violant when I get down on it. Scared the piss out of me the first time out, I've givin people rides on it and you can't tell you have that extra weight there, it just helps plant the tires for traction. You bet I'll have Jeff do more porting later on some cubs, I'm real happy with it. You can't go wrong.

My (terribly jetted) 68 mm stock stroke cub got beat twice by a Banshee with Jeff's dune port, stock stroke, stock carbs. I beat him the third time but he got a hell of a hole shot, running 11 paddle haulers. I adusted my jetting, but didn't get to run him again. He shouldn't have been near as close to me as he was. I outweighed him by 50 lbs and I was just getting the hang of taking off with my new 10 paddle extremes.

 

 

However, the motor was damn impressive considering he had stock carbs!!!!!!

Same sorta thing happened with me & Rippen. We both got our engines back about the same time and the first couple times we races Rippen was right with me if not in front of me. That was a long time ago though and we were both off a lot on jetting. we haven't run them again since them, but it was damn close that time.

 

I do all my own work, rippen had all his stuff done by FAST. I'm kinda eager to race him again now that I got jetting where it should be, I'd like to see how my stuff does against a professional builder. I've always been a home-shop guy and only send stuff out for porting, everything else done in-house. Not sure I will send stuff out for porting any more either, I will probably go back to doing my own porting as well, like I did on a few stock cylinders.

 

Jeff appears to know his shit though, I will give him that! Rippens bike runs good! I was really impressed when I rode Rippen's banshee for the first time.

You should ride it now that he has "full throttle" . When i checked his carbs at Idaho i was like "wtf"? Why do you only have the throttle slides opening halfway?? LOL Rippen was like OMG, i cant believe i did that! I had to give him some shiat over that.

Hey now, having the slides only open halfway happens, its not a stupid mistake. :cool:

 

I did it the first, oh, year I had the shee.

Jeff charged me a life time friendship and life time pizza, he really likes to eat. Should have just paid him cash. Man am I broke for life. LOL. You can call Jeff and see what he would charge you, I don't like giving that kind of info out with out Jeffs okay, He did treat me real good though, I'm sure he would treat you right. Give em a hollar, he a real good guy and blast to talk to. Gipperz
