cool cam sprocket bill!billp

PeWe · « **Reply #401 on:** June 27, 2016, 03:04:27 AM »

Yes, no need of timing cam when sprocket is fixed

I saw that a check to verify correct timing was done...

Sprocket not fixed, is slotted so you can adjust, Bill

I think my RC sprocket has the holes drilled in new locations.. 4 additional holes..

Bill/BentON Racing · « **Reply #404 on:** June 27, 2016, 08:54:42 AM »

Early ones were drilled, later ones were slotted.

PeWe · « **Reply #405 on:** June 27, 2016, 10:38:21 AM »

OK, I did not see the slot. Bolt head cover it if it is the photo on previous page. Shorter slot than APE and Falicon sprockets, right?

I thought the same thing PeeWee. The picture made it seem to be fixed. My RC sprocket has a larger slot.

Bill/BentON Racing · « **Reply #407 on:** June 27, 2016, 02:20:00 PM »

Yep, y'all are correct, slotted but not as much as some others! And for what it's worth, on stock marks, intake was opening at 45 BTDC, should have been @ 31. Why you should degree your cam if possible, Bill

Did you start it yet Bill?? Where's the new YouTube videos??

Bill/BentON Racing · « **Reply #411 on:** June 30, 2016, 03:24:40 AM »

You will hear it soon enough! Lol. Yes, she's up and running as of @,6:30 last night! Yippee Kai Yeah, it sounds good! Calling on dyno appointment today, sure do hope it works out. No elec trailer hookups for Memphis. Guess we get to listen to the generator for 3 days. Video later after work, Bill

How many points on the shave and true job

Bill/BentON Racing · « **Reply #413 on:** July 01, 2016, 04:58:38 AM »

Used a different head, Butch Pace one. It was ready to go on, was decked but don't recall how much. Yes , new Cometic copper. 050. Dyno on the 13/14th. Commerce next Friday night for some shakedown passes is the plan for now. Just finished up air shifter last night. Bill

Bill,

Bring that bike to Darlington tomorrow. ET bracket race. You and Donny can throw it on the back of the truck to save some gas. You won't need any wrenches cause the bike is perfect this time around. Anything else, I'll have in my trailer.

Bill/BentON Racing · « **Reply #415 on:** July 01, 2016, 08:37:57 PM »

Gotta put on safer handlebars tomorrow. I'll wait til Friday night. Frank, this is like a new bike, everything has been changed. Better to make sure. Now if Friday works out, may run Commerce on Saturday, Bill

dragracer · « **Reply #416 on:** July 02, 2016, 01:30:08 AM »

Understood Bill. I thought you had already changed the bars out. Also felt this could have been an opportunity for you to mainly make 1/4 mile test passes without the hassle of the Commerce crowd. This event will be going on all day. But I realize its a long distance to drive just to be sure your equipment is ready for Memphis. Nevertheless, get as much seat time as you can. The dyno results aren't going to teach you how to ride that bike, no matter how good the numbers look on paper.

Good luck at Commerce next week. We've only got 21 days left to get right.

Bill/BentON Racing · « **Reply #417 on:** July 02, 2016, 04:40:49 AM »

Frank, I changed them before Rockingham, but not the correct ones. Getting ready to install today, going try to make Friday night early, thanks, Bill

Watched " GOT BRUCE " break the right bar off a set of Z-BARS right off the line = watched my rider Ron Saint break the left side off that type Z-BARS right off the hit, they both got stopped = LUCKY. One piece bars I never seen broke, that welding on those Z- BARS and the chrome plating hide the rusting and cracking on the inside...... better be safe then sorry. Watched a top AHDRA Harley racer break off the triple tree at the big end at Bradenton 2002 and he got that Beast stopped. No bling bolts BILL !!!!!

LOL!

I pictured Bill wandering around the pits picking up other peoples wrenches just to "hold them"!

Bill/BentON Racing · « **Reply #423 on:** July 02, 2016, 07:31:13 PM »

LMAO, I hope I'm in the glow of 10 second passes! Sure feels good to be going next week to test and tune. Hope I'm done with this one for a while. Bill
