Oh man, I invite Slavy to come out to SC & ride the Dragon but then my bikes don't work. OK, pay back time; Slavy finds a photo of me that ... well, it's not exactly my best image. Yea, ok, well what are friends for ? ?
The bike photo is of
REX which was supposed to make the Dragon ride but had last minute issues with oil loss. I have since replaced the valve stem seals and the head is back on, but still need to install high lift cam/chain, etc.
I am trying to get it back together this week but with kitchen makeover work and prep for our 35th anniversary trip coming up next week, time is at a premium.
I decided to not put the big piston in it right now ... short on $$ fun stuff, but will just hold it until I can save up my penny's for Bore-tech's fine work. The engine ran very will before but since then the exhaust ports have been reworked, 0.040" shaved from head/cyl which should yield almost point higher compression, and replaced standard Performance Camshaft with the higher lift version.
I have 3 carbs to work with. Older model 38mm Edelbrock which is seen in the photo; new 38mm Edelbrock with acc. pump, and a 38mm Mikuni with UFO with closed pilot jet, the new version of the Dial-a-jet with bar mount dial selector, and ... ah ... something else but my brain has gone blank for now. Anyway, plenty of carbs on hand to play with.
The photo shows the carb mounted on a 90 deg. elbow but I plan to replace that with a 45 deg mount if it will clear the frame, in order to get a straighter shot into the intake.
I also have a 6" velocity stack, and several filters for the carbs. Some fit here & others there.
After I get a decent road tune on the carbs I hope to get some dyno time at
76 Cycle, owned by John who works on older model HD's. He is one of the good guys from the HD world, and is interested in what I'm doing with
REX.
Anyway, I would like to get dyno runs with each of the carbs, get them fine tuned if needed, and compare those dyno numbers with what I get from the Veypor program.
